Introduction
Grazinglands Spatial Analysis Tool (GSAT Basic) is a stand alone decision support
tool utilized to inventory grazing resources and animals (domestic and wild). This
application is used to assess the relationship between grazing supply and animal
demand. It can help determine the best level of stocking to meet the needs of the
land and the grazing animals. GSAT was developed to assist in the conservation
planning process on grazing lands. This tool combines the inventory process of
grazinglands in combination with spatial analysis tools to provide accuracy and quick
alternative assessments for resource planning. This tool offers the land planner a
method to assess the forage supply in relationship to the animal demand. GSAT
offers a simple process to generate new files or access existing files through
Customer Service Toolkit (CST). Reports such forage and animal balance can be
generated as well as a comparative evaluation of each alternative which can be
saved in the customer’s file. Each of these reports can serve as documentation for
required management in agency programs.


   ♦   It can be used by NRCS personnel, Technical Service Providers, Cooperators
       and/or other agencies wanting to participate in conservation planning process
       as part of our grazing land planning programs nationwide.
   ♦   Users can import and integrate client and geographic information from
       Customer Service Toolkit or other digitized sources of information.
   ♦   Determine spatial analysis of water and grazing distribution within GSAT.
   ♦   Inventory and analyze grazinglands leading to a balance between animal
       demand and forage / roughage supply.
   ♦   Create supporting documentation for Prescribed Grazing Standard (528).
       Output in graphic and / or tabular forms.


Note: Instructions on CST and ArcMap for users unacquainted with these tools are
located in the Appendix of this manual.

Chapter 1 – GSAT startup
The user can import customer data from Customer Service Toolkit such as the
planned land units and soils data layers. Refer to Appendix A for instructions on CST
usage and ArcMap mapping in Appendix B if you are an unseasoned Toolkit user.
To export data from CST that has already been completed user should check out
customer folder, click on Tools in CST and select the drop down list and select
Export Customer Data. After the export tool has completed Click OK and click Tools
again, from the drop down list, click on GSAT to open the program from CST. Follow
the directions below to attain a Forage Animal Balance.
   1. When the GSAT program opens the Plan tab is selected showing plan
      information and customer information.
   2. Select the Import from Toolkit button at the top of the window.
   3. A Select a Customer window appears, Select the customer that you have
      imported from CST that you wish to work with click OK.
   4. A Select a Plan window appears, Select the plan you created in CST, This will
      be consplan if you did not rename it in ArcMap. Click OK.
   5. The session.xml file transfers customer data from CST into GSAT. This
      information includes the customer’s name and address (from SCIMS) on this
      page and field geospatial data which will be under the Forage tab.
  6.   Enter a scenario name in the Name field. Be specific as to what the scenario
       is (e.g. “Brown Ranch Benchmark, 2007” or “Brown Ranch Alternative #1,
       2008”). Whatever you enter here will appear on graphs and reports for the
       scenario.
  7.   Select the AU method you wish to use either Air Dry (30lbs/day) or Oven Dry
       (26lbs/day). Whichever method you select, make sure all the data entered is
       in these units: do not mix air-dry and oven-dry figures.
  8.   Select the start month of the plan and type in the Start Year of the plan. You
       can alternatively use January as the start month and let the analysis tell you
       which start month is more appropriate. You can change the plan start month
       any time and check how the reports look (the reports and graphs are changed
       as well).
   9. Click on the Forage
      tab and notice the
      Geospatial land units
      have been imported as
      well as field attributes
      (Name and Acres).

Chapter 1.1 – Conservation Planning with GSAT
GSAT can help you quickly and accurately develop: 1) forage and roughage supply,
2) herd and wildlife demand, and 3) the resulting balance on a planning unit during a
12-month period. The program can be used for conservation planning, contracting,
program eligibility, and status reviews (entering grazing records) among other uses.
Because it can quickly tell you the effects of changes to supply and demand, a
number of alternatives may be developed from a Benchmark to treat resource
concerns.
   1. Whenever possible, gather the resource inventory, productivity, and condition
      information in the field with your client. Production values from soil surveys,
      tech guides, ecological sites, forage suitability groups are generally not
      recommended because they are usually based on the highest combinations of
      management and productivity.
   2. Know what data elements GSAT needs and what products it can deliver and
      prepare your field data accordingly. Work with local experts and specialists to
      develop and enter Resource Data that can be used in your work area
      (animals, growth curves, ecological sites, and forage partition profiles).
   3. Develop a Benchmark scenario to determine problems (and the magnitude of
      the problems) with imbalances in supply and demand. Look at reports and
      graphs to see if the overall balance is positive or negative, and if there are
      months where any of the Accumulated Balances fall below zero; these are
      indicators of shortages in forage or roughage and can indicate resource
      degradation.
   4. Change the Plan Start Month on the Plan tab to more accurately model
      carryover forages and roughages; seldom will the ideal planning year coincide
      with the calendar year.
   5. Review the Benchmark analysis with the client and determine which changes
      can be made that are practical and feasible on the unit to eliminate resource
      problems. Any of the data elements in GSAT may be changed to develop an
      alternative or sets of alternatives. Make changes and check reports and
      graphs as you plan. A few examples of what could be changed include:
          a. Land Unit Layer: fence locations, forage partition profile, land use, add
             fields (acres)
          b. Inventory Sites Layer: Ecological Site/Forage Suitability Group, Growth
             Curve, Yield (productivity), add/modify inventory polygons
          c. Water Point and Water Distribution Layers: add/modify water points,
             change set water distances (change adjustment factors), recalculate
             water distribution layer
          d. Adjustment Layer: add/modify polygons, adjustment factors
          e. Response Unit Layer: modify inventory site, growth curve, forage
             partition profile, adjustment, and yield
   6. Review the Alternative(s) analysis with the client and determine a selected
      alternative or continue planning alternatives. Acceptable alternatives have a
      positive overall balance and at no time does the Accumulated Balance go
      below zero (check graphs and reports).

Chapter 2 - Resource Data
The Resource Data portion of the program stores data that can be used for all
clients. You can create local, regional, or even client-specific data. You can save,
export, and import data from other GSAT users or import data developed by
specialists. Exported files are small and can be emailed easily. The data is exported
in either XML or comma-delimited file types and can be viewed with Internet
Explorer or MS Excel, respectively.
Some data (ecological sites/numbers and growth curves, can be downloaded from
the ESIS database; click on the GSAT Downloads button on the left side of the
screen (http://esis.sc.egov.usda.gov/Welcome/pgESDWelcome.aspx).
   1. Click on the Resource Data button at the top of the page to begin entering
      or importing the Animal, Growth Curves, Ecological Sites, and the Forage
      Partition Profiles that will be used in the selected area. Notice that clicking
      this tab opens a new database that allows you to enter localized resource
      information.
   2. Note: Information for these databases only needs to be entered once for
      each geographical area. It is likely that someone has already entered this
      data for your area. If not, contact your area or state grazing specialist for
      correct data to be used in planning. This information can be expanded to suit
      specific client or local needs at any time.
   3.    An example data set is provided for import under My Documents/My GSAT
        Files/Example Resource Data/.

   3. Enter the kind of animal you will be dealing with in the Name field. Then
      animal kind could be sheep, cattle, horses or any other general animal type.
   4. Under the Animal Class click the Add button to create the animal for each
      animal kind.
   5. An Animal Class window will appear. Enter a descriptive name for the animal
      in the Name blank. If you are dealing with Cattle for the Kind of animal,
      names could be Cows, Cows with calf, Bull, Steer, Heifer, etc.
   6. Select the Sex of the animal.
   7. Enter the weight of the animal.
   8. Choose the intake of the animal as a percent body weight. This will calculate
      the AUE for that animal.
   9. Click OK.
   10.Click the Add button to continue entering Animal groups.
   11.When finished adding animal groups to the list click the Save button when
      you are ready to move to the next animal kind. Note: When you are in a
      particular screen, always use the buttons that come with that screen. The
      buttons at the top of the GSAT program screen are to save the entire plans
      (scenarios).

Chapter 2.2 - Growth Curves
The Growth Curves form allows you to build plant growth curves for the plant
communities (ecological sites or forage suitability groups) in your area. A growth
curve is a graph that details the percent of plant production each month in a year.
GSAT also calculates the accumulated amount of growth but it is not shown on the
screen. The upper portion of the screen allows you to describe the growth curve and
the lower portion of the screen lets you enter plant production percentages for each
month of the year.
   1. While staying in the Resource Data Section, Click on the Growth Curves tab
      to enter data into this data base.
   2. Click the New button to create a new record to enter growth curves. (The
      first time you enter information for a growth curve, GSAT will automatically
      create a new Growth Curve Record.)
   3. Enter the 6 digit ID for the growth curve in the field labeled Code. This code
      should consist of the 2 letter postal code for your state and a four digit
      numerical code. For Example: SD0001. Ecological sites and forage suitability
      groups downloaded from ESIS will have the site or group number in this field.
      The Code and Name must be unique to identify the record.
   4. Enter the name of the growth curve in the field labeled Name. . Ecological
      sites and forage suitability groups downloaded from ESIS will have the site or
      group name in this field.
   5. Write a brief description of the growth curve in the field labeled Description.
   6. Enter the monthly percent of plant growth in the month fields under the
      section labeled Percent of Total Growth by Month. Round these percents to
      the nearest whole number. The total must equal 100 or an error message will
      appear in the window. You can get these percents from clipping studies,
      expert opinions, plant growth models such as PHYGROW, etc.
   7. Click the Save button to save the record when you are ready to move to the
      next growth curve.

Chapter 2.3 - Ecological Sites/Forage Suitability
Groups
The Ecological Sites form allows you to compile a list of the ecological sites, forage
suitability groups, or other land use identifiers found in your area. The Ecological
Sites form stores the data for future use in the program. Note: Only the Site Name
and Code are stored in this data base at this time. Code and Name must be unique
to identify the record.
   1. While in the Resource Data screen, select the Ecological Sites tab.
   2. Click the New button to add a new record. (The first time you enter
      information for an Ecological Site, GSAT will automatically create a new
      Ecological Site record.)
   3. Enter the National Code for your ecological site in the Code field. Note: The
      National code consists of the following:
          a. 3 digit numerical MLRA
          b. 2 digit alphabetical sub-MLRA
          c. 3 digit Numerical site identification

Chapter 2.4 - Forage Partition Profiles/Pasture
Budgeting
The Forage Partition Profile Form allows you to compile schedules for different types
of land. These profiles tell GSAT how Growth Curves are partitioned: different
portions of the growth curve may be used for different activities. These may be
designed to work over a geographical area or custom made for a particular client.
   1. Under the Resource Data button, Click on Forage Partition
      Profiles/Pasture Budgeting tab.
   2. To enter a new profile record Click the New button. (The first time you enter
      information for a Forage Partition Profile, GSAT will automatically create a
      new Forage Partition Profile record.)
   3. Type in the name of the profile in the Name field. This can be identifiers such
      as All Graze, Harvest Roughage, etc. The Name must be unique to identify
      the record.
   4. Type in a brief Description of the profile such as year round grazing, hay
      cutting, etc.
   5. Click the Add button under Forage Partition Activity to begin adding the
      profile activities.
   6. A data entry window will appear. Enter the Start date and End dates of your
      grazing or roughage practice activity. Select the management activity, and
      then enter the harvest or grazing efficiency percentage. Click OK.
   7. You can add as many rows in the activity section as needed to correctly
      partition the management activity throughout the year. For instance, if you
      wish to get 2 hay cuttings per year in July and October, enter 1/1/06 for start
      date, 6/30/06 for end date, select Harvest Roughage, enter harvest % click
      OK. Click the Add button again; a new window will appear for your second
      cutting. Enter start date of 7/1/06, end date of 9/30/06, select Harvest
      Roughage, enter the % harvest efficiency and click OK. This will get you to
      the first of October.
   8. To complete the year, you will need to add another row, and start date
      10/1/06, end date 12/31/06, and select activity such as restricted use, or
      always available, and enter the % harvest efficiency.
   9. Click the Save button to save the record when you are ready to move to the
      next Forage Partition Profile.
   10.Click the New button to create the next Forage Partition Profile.
   11.Use the Restricted Use choice when you will not graze a pasture or it is not to
      be counted in the plan (farmstead or homestead, corrals etc.)
   12.Use the Land Practice choice when you will remove the forage by something
      other than grazing animals i.e. prescribed burning.
   13.Forage Partition Profiles may be exported and imported the same way as
      Animals, Growth Curves, or Ecological Sites/Forage Suitability Groups. Save
      your files in a way that you will know where, and what they are.
   14.This completes the Resource Data entry. Remember you can always return to
      the Resource Data tab and add or adjust data to maximize client specific or
      local specific resource needs.

Chapter 3 - Client Data
The Client Data section is where you enter the forage and roughage supply and the
animal (livestock and/or wildlife) demand to reach a forage animal balance for your
client. We will go through the various steps beginning with the Land Units, then to
Inventory Sites. We will then go through the rest of the layers (drawn, imported or
calculated) ending up with the Response Unit layer which calculates the amount of
forage and roughage available for grazing. To get started, click on the Client Data
button at the top of the screen.
   1. Open GSAT by clicking START, All Programs, USDA Applications, Grazing-
      Pasture Tools, Grazingland and Spatial Analysis Tool, GSAT. (Notice that the
      User Manual and Quick Start documents are also provided for your use.)
   2. When the GSAT program opens, the Plan tab will be selected. Fill in the plan
      information and the customer information. Be sure the correct AU method (Air
      Dry (30lbs/day) or Oven Dry (26 lbs/day)) is selected. Click on the Save As
      button to save the plan. Note: Whatever you enter in the Name field will
      appear on all graphs and reports. Make the name meaningful; identify it as a
      benchmark or alternative and enter the client’s name, unit name, planner
      name, etc. Notice that the field will hold more text than can fit into the
      visible portion of the field.
   3. Browse to a directory that will be remembered for later retrieval. Be sure to
      name the plan so you can identify it later. The default directory is My GSAT
      Files (created under C:\Documents and Settings\firstname.lastname\My
      Documents). You may alternatively choose to save the file in the checked-out
      CST customer folder. A GSAT folder is created for every new client and can
      serve as a repository for all GSAT-related files, reports, and shapefiles.

Chapter 3.1 - Land Units
The Land Unit Layer allows you to define and describe the different management
units or fenced pastures of the client’s ranch. You can import this from CST, draw it
on the Map screen, or enter it in a simple spreadsheet.
   1. Select the Forage tab on Main GSAT upper tab row then select the Map tab
      on the lower row of tabs.
   2. Select the Land Unit Layer button to the left of the screen. Note: The
      green check mark in the box signifies that the layer is turned on (visible); you
      must click on the button itself so that it is recessed to enter data for that
      layer.
   3. Notice that the .xml files transfer that was done through CST shows the
      names (Field #) of the fields or management units and the acres associated
      with each field. These are done when you apply attributes to each field when
      mapping in CST.
   4. Select the field that you wish to enter data for (either click on the row in the
      spreadsheet or the polygon on the map). The field selected will turn yellow
      on the map and the associated spreadsheet line will turn blue.
   5. Click on the Edit Feature button just above the map and spreadsheet. This
      will open a Land Unit window to enter data for that field.
   6. You can enter a description of the field in the description blank. This may be
      helpful later on describing pastures to a client.
   7. Click field marked Forage Partitioning Profile for a drop down the list of forage
      partitioning profiles that you may select from. (The forage partitioning
      profiles may be found in the Resource Data section of the program.)
   8. The Acres field should be already calculated if you imported the layer from
      toolkit.
   9. The default Forage Partitioning Profiles (they can be changed at the Response
      Unit level as well) must be entered for each field for calculations to be
      completed. If you miss one, an error message will notify you when you try to
      calculate the Response Unit Layer.
   10. After all fields are populated you may move on to the Inventory Site Layer.
   11. Note: It is a good idea to click the Save button at the top of the screen after
      user enters data for each layer. This will save the information to the client’s
      file. The first time you save a client’s file, a Save File window will appear.
      Note that the directory it is saving to is My Customer_Files_Toolkit. User will
      have to give the file a name and it will have a .gsat extension. Remember to
      give the scenario a unique name that will help you identify the file later.

Chapter 3.1.1 - Entering Land Units with GSAT
Mapping Tools
To enter data and draw a map using the GSAT Software without using
ArcMap or CST, use these instructions.
Many of the steps are somewhat like ArcMap in the way the user chooses to build the
layers necessary (land units, inventory sites, etc.) to attain the response units for
the area. The Land Units layer is simply the boundary and cross-fencing of a grazing
unit. Note: Use this method only for the simplest scenarios. Drawing multiple land
units (splitting, cutting, etc.) is easier and more accurate in CST. This method works
well though for simple units. Hand-drawn layers are not georeferenced and
cannot be exported and imported into ArcMap!
1. Click on the Forage and Map tabs. Here you will begin drawing the boundary
   layer and or the land unit layer of the client’s property. First select the Land Unit
   layer on the left of the screen. Select the Draw button.
2. A Cross will appear in the white window of the screen
3. Left click the mouse once to set starting point. Move around in a clockwise
   direction and click again to set second corner point. When you are at your last
   corner, double click mouse and line will snap to point 1. The boundary is now
   set.
4. Select the Split feature tool to develop Management Units or Land Units. A
   drawing cross will appear when you enter the white surface of the mapping area.
   Start outside the boundary and left click once to begin drawing the split line. Go
   outside the boundary on the other side and double click to split the field.
   Continue this until all fields are mapped in. Note: Click on the Select Arrow
   when done to avoid drawing extra lines.
5. Now you may begin selecting fields and adding attributes to those fields such as
   the Name, Description, Default Forage Partition Profile, and acres.
6. Attribute the land unit features by highlighting a polygon or row in the
   spreadsheet and clicking the Edit Feature button.
7. Note: You
   must set each
   field to the
   correct acreage
   when you edit
   feature for each
   field! You can
   also use the Set
   Boundary
   Acreage button
   to define the
   total acreage –
   you may still
   need to adjust
   the acreage on
   each land unit
   though.

Chapter 3.1.2 –Entering Land Units Using GSAT
Spreadsheets
To enter data without drawing a map or using CST, use these instructions.
The Land Units layer is simply the boundary and cross-fencing of a grazing unit.
1. Click on the Forage, Map, and Land Unit tabs. Click on the Add button.
2. Enter the Name, Description, Forage Partition Profile, and Acres of the fenced
   unit. Click on the OK button when you are done.
3. Continue entering and attributing fenced land units by selecting a row and
   clicking the Add button.
4. Click on the Save button to save your work.
5. Note: You must enter the acres of each fenced unit: the Set Boundary Acreage
   button on the Map tab will not work with this entry method.

Chapter 3.2 - Inventory Sites
The Inventory Sites Layer allows you to identify different areas of different
productivity on your client’s ranch. These sites can be imported to the GSAT map
from the CST Ecological Site Map or productivity shape files created using Soil Data
Viewer. You may designate your inventory site as either an ecological site, forage
suitability group, or any other label as needed. If there are significant differences in
the productivity within the inventory sites, you can draw these areas in after the
import of the shape file has been done. For best results, make sure you have areas
of different productivity outlined (as polygons) and that you have either field-
collected data or other reliable production data to attribute each polygon. Having
the minimum number of polygons (rows in the spreadsheet) is recommended.
   1. Click on the Inventory Site button on the left of the GSAT map screen.
   2. Click on the Import button in the map section to import the ESD shapefile
      you have saved earlier in CST.
   3. An Open Window will appear. Move through the directory to where you saved
      the shape file, highlight the file and click Open.
   4. You now have a spread sheet and the site delineation lines on the map. The
      acres of each inventory unit are calculated for you.
   5. Note: When this process is done, many times there will be sections that have
      “0” acres. These are slivers that are created, usually under fence lines. You
      can highlight these areas on the spreadsheet and Click the Delete Selected
      Features button to remove these unusable areas.
   6. Select the inventory site you wish to start with. The site will now be in yellow
      and the corresponding spreadsheet line will be blue.
   7. Select the Edit Feature button above the spreadsheet. An Inventory Site
      window will appear to enter descriptive resource data for that field.
   8. Fill in the name blank with the field number, Description of the field (local
      land use).
   9. Click the drop down list for Ecological Site and select the correct Ecological
      Site or Forage Suitability Group for that particular inventory site. (These are
      stored in the Resource Data Database)
   10.Choose the Growth Curve from the drop down menu in the growth curve
      column. (These are stored in the Resource Data database.)
   11.Enter the Yield for that particular inventory site. When all fields in the
      window are complete, click the OK button when you are done.
   12.Repeat for each inventory site.
   13.A Name and Description can be entered for each site if so desired but is not
      necessary for forage animal balance calculations.
   14.Ecological Site, Growth Curve and Yield fields must be populated to get a
      forage animal balance.
   15.Click Save at the top of the Screen when you have completed entering
      Inventory Site Data.
   16.You are now ready to move on to the Response Units to calculate the total
      supply of forage available for the client. Water Points, Water Distribution,


GSAT Basic User’s Guide                                                      page 19
      and Adjustments will be covered later. These resource factors do not have to
      be supplied to get a basic forage animal balance.

Chapter 3.2.1 - Entering Inventory Sites Using GSAT
Mapping Tools
When there are no soils or ESD shape files to import from CST, or it is feasible to
draw in inventory sites by hand, follow the instructions below to complete the task.
1. Click on the Inventory Site button on the left of the screen.
2. Click on the Draw button. A drawing crosshair will appear in the screen.
3. User must trace the ranch boundary again to set the inventory site boundary.
   Be sure to stay as close to the boundary as possible to alleviate any extra or
   missed acres in the inventory sites. Follow the same guidelines as in Chapter
   3.1.1 to draw map.
4. Notice that the new inventory site boundary is in Green.
5. To split field click on the Split button. Start outside the boundary line and click
   once. Follow your inventory site (Soil Line) clicking once for every turning point.
   The more you click, the curvier the line will be if this is so desired.
6. Once you reach another boundary, double click on the outside of the line to
   complete the drawing.
7. Notice the lines turn green and snap to boundary after double click.
8. When all inventory lines are drawn, click on the Select button so unwanted lines
   will not be drawn.
9. Attribute the Inventory Site features by highlighting a polygon or row in the
   spreadsheet and clicking the Edit Feature button.
10.Follow directions in Chapter 3.3 on to complete a GSAT plan without the use of
   CST. There are no more drawing actions required with the stand alone GSAT
   Basic (unless Water Points, Water Distribution, and Adjustments are desired).

To enter data without drawing a map or using CST, use these instructions.
The Inventory Sites layer is simply the different productivity areas of a grazing unit.
1. Click on the Forage, Map, and Inventory Site tabs. Click on Add.
2. Enter the Name, Description, Acres, and productivity of the site. Select an
   ecological site and growth curve from the drop-down menus.
3. Continue entering and attributing inventory units.
4. Click on the Save button to save your work.
5. The total of acres of the inventory sites must equal the total acres of the Land
   Units. Note: In most cases the Inventory Sites polygons represented in the
   spreadsheets should be the same area as the fenced Land Units for ease of
   entry. If they are different, either draw the Inventory Units (and Set Boundary
   Acreage) or import from CST.




GSAT Basic User’s Guide                                                      page 22
Chapter 3.3 – Calculating Response Units
The Response Unit calculates the amount of forage and roughage available for
grazing during the planning year. GSAT uses the Land Unit, Inventory Site, Water
Distribution, and Adjustments layers to create a layer that shows all the spatial
combinations of forage/roughage supply. Combinations of land use, fenced unit,
productivity, accessibility, forage partitioning, water distribution, and other
adjustments are automatically calculated.
You can calculate the response units anytime. When developing alternatives you can
re calculate the response units layer after changing fencing, land use, productivity,
etc. and view reports and graphs to see what your changes have been made to the
supply, demand, or balance. Note: If you make changes to rows/polygons in the
Response Unit layer and then recalculate response units, your changes will be lost.
Note: You must have the Land Units and Inventory Units layers created before using
the Calc Rsp Unit Layer button. You may alternatively have the additional Water
Distribution and Adjustments layers created to create a response unit layer with
more detail; depending on your client’s needs.
   1. Click the Response Unit button on the left hand side of the screen to make it
      the active layer.
   2. Click the Calc Rsp Unit Layer button above the spreadsheet to create the
      Response Unit.
   3. GSAT will automatically create this layer using the other layers as a
      reference. Additionally, GSAT will automatically enter all of the information
      that appears in the overhead spreadsheet.
   4. The forage/roughage supply has now been calculated. Click Save at the top
      of the screen to save client information that has been entered.
   5.    The user can make adjustments for forage availability in this screen by
        selecting the response unit. Click on the Edit Feature button. Locate the
        Adjustment field and enter the required adjustment. For instance a 40%
        reduction in forage would be 60% usable forage and the number entered in
        the adjustment field as shown above. More information on Adjustments will
        be covered in Chapter 4.2.

Chapter 3.3.1 - Entering Response Units Using GSAT
Spreadsheets
To enter data without drawing a map or using CST, use these instructions.
The Response Units layer is simply the combination of Land Units and Inventory
Sites of a grazing unit.
1. Click on the Forage, Map, and Response Unit tabs. Click on Add.
2. Enter the Name. Select a land unit from the drop-down menus – notice that the
   forage partition profile is automatically selected. Select an inventory site from
   the drop-down menus – notice that the growth curve and yield are automatically
   selected. Enter the acres of this response unit.
3. Continue entering and attributing response units. Note: You can change any of
   the default selections (although you generally shouldn’t need to while using this
   method). Growth curve, forage partition profile, adjustment, acres, and yield
   may all be changed at the response units level.
4. Click on the Save button to save your work.
5. The total of acres of the response units must equal the total acres of the Land
   Units. Note: In most cases the Response Units polygons represented in the
   spreadsheets should be the same area as the fenced Land Units and Inventory
   Sites for ease of entry. If they are too different, use the drawing tools to create
   a Land Units and Inventory Sites map and use the Calc Rsp Unit button to
   create the Response Units (or import these two layers from CST).

Chapter 3.4 - Herds
This form allows you to define the client’s herd inventory and calculate demand. A
herd can only be comprised of a single species of animals but a single species can be
represented in multiple herds, e.g. three cattle herds, two goat herds and one sheep
herd sharing a pasture. It is important to note that you can simply specify a kind of
animal and the number of head for one class with an average AUE value and stop at
that point if you feel that it is sufficient to characterize demand of the herd. The
program will automatically fill the same number of head in each month and assign
the same monthly AUE value all through the year. However, if you want to represent
more than one class of animal and alter the demand profile of the herd you can go to
each month and adjust the animal numbers and/or the AUE values.
   1. Click the New Herd button to create a new record to enter herd information.
      The first time you enter a herd, GSAT will automatically create a new Herd
      Inventory Record.
   2. Name the herd in the Name Field. Naming conventions should reflect names
      that the producer can readily recognize. If you anticipate splitting a herd at
      some point such as 2 bulls going to one herd and 4 bulls going to another
      herd during the breeding season, it is best to recognize those two groups as
      two separate herds for scheduling purposes.
   3. Select the Animal from the drop down list. (These are the animals and AUE’s
      that you set up in the Resource Data.) If you wish to add an animal kind,
      return to resource data animal’s screen and input the correct data. Return to
      this screen and the new animals will be available for use.
   4. Click on the Add Class button under the Annual Herd Structure, a Herd
      Group Editor window will appear. Click on the Animal Class field and a drop
      down list will appear with the animals that you have listed from the Resource
      Data database for that animal class.
   5. Enter the default head in the provided field and hit the tab key or click
      somewhere in the table. The number of head values will automatically
      populate in each month field for the entire year. Notice the default AUE is
      populated as well.
   6. If you feel the default AUE value is not correct for your situation, you can
      change the value to fit your needs.
   7. If you wish to adjust the monthly values, you may click into the desired field
      and change the value in any month for example growing animals.
   8.   Enter the % forage demand and the % roughage demand for each month.
   9. When all fields are completed to satisfaction for that animal, click OK.
   10. Add as many Classes of animals for that herd as needed by clicking the Add
      Class button.
   11. When you have the herd built, click the Add/Update Herd button to add the
      herd to the client’s inventory.
   12.To add another herd, Click the New Record button and repeat steps 2-11.
   13.Click the Save button at the top of the GSAT screen to save work to Client’s
      database.




GSAT Basic User’s Guide                                                     page 25
You now have the information stored to calculate a Forage Animal Balance. You can
go to the Graphs and Reports Tabs to view calculations. However, if you wish to add
water points, water distributions, and adjustment layers to further enhance the
resource forage animal balance for the client, follow the next set of instructions.

Chapter 3.5 - Roughage
The Roughage form allows you to track and balance the roughage your client will
feed the herd(s). The Roughage form is designed to account for all of the harvested,
bought, or sold roughages that are used and/or available on the unit for the planning
year. You can model roughage supply in AUMs or Tons as preferred by your client.
Note: Demand for roughages is set in the Herds form and is only calculated on this
form.
   1. Click on the Roughage tab to open the roughage form.
   2. Roughage harvested on site will be controlled by the forage partitioning
      profiles applied to Land Units and/or Response Units. A harvest roughage
      partitioning profile must be created and applied for the period growth will be
      harvested for the appropriate management unit. Once a forage partitioning
      profile has been applied to a management unit, the expected amount of
      forage harvested will automatically be calculated in the first row; both
      monthly yields and total annual yield will be calculated.
   3. Enter the amount of stored or previously acquired roughage in the box
      provided at the top left of the entry cells.
   4. Next enter the amount of forage your client buys or sells and the appropriate
      month in which your client chooses to do so.
   5. Note the Demand for roughage, which is set in the Herd tab, Herd Editor
      Window (not on the roughage screen). The demand is for all herds that have
      some roughage demand set (by month).
   6. Select the radio button to show how you want the roughage to be viewed,
      either AU, AUM, or Tons.
   7. When you are through, click the Save button to save your changes. Note:
      The Roughage Summary report is a copy of this screen.

Chapter 4 - Water Points, Water
Distribution and Adjustment Layers
These additional layers and tools allow the planner to do a more complex analysis of
grazing unit resources. Where distance to water affects livestock distribution and
forage utilization, the water points and calculated water distribution layers can show
where distribution problems exist and suggest alternatives for treating them.
The Adjustment layer can serve many functions; use this to describe limitations to
physical access (by livestock) due to slope, barriers, incompatible grazing land uses
(farm stead, gravel pit, water, blowouts), or any other constraint to the adjustment
factor you encounter. This layer may be designed in ArcMap or within GSAT and can
even substitute for the calculated water distribution layer.

Chapter 4.1 – Water Points
   The Water Point Layer allows you to specify where the animals on your ranch will
   have access to water. This will help GSAT predict grazing patterns or radii for the
   animals. You can set water points manually within GSAT or import the shape file
   from ArcMap in the same manner as importing Ecological Sites shape files.
   1. Click the Water Point button to the left of the map in the Forage screen.
   2. If you have previously created a water points shapefile in ArcMap, click on the
      Import button, browse to the water points shapefile and import the water
      points; proceed to step 8.
   3. If you wish to create the water points shapefile within GSAT, click the Draw
      Point icon to begin setting your water points.
   4. Locate water sources within the planned land units.
   5. Click once on the pond or tank to set the water point. A small blue dot will
      appear to show that you have set the water point.
   6. Continue finding and setting all remaining water points.
   7. Notice as each water point is set a new row in the spreadsheet appears; you
      can name and describe each point in these fields. You may want to number
      the points or describe what type of livestock water access the point refers to.
      Note: To describe a stream or other continuous source of livestock water,
      enter points along the stream at ¼ to ½ mile intervals; the program will use
      all of these points to calculate water distribution and will not artificially limit
      availability to water.
   8. Select a water point and click Edit Feature button to name and describe a
      water point. Enter the desired information in the fields provided. Note: It is
      much easier to click on a row in the spreadsheet rather than selecting a water
      point on the map.
   9. Click OK when you complete entering the desired information.
   10.Once all the water points are identified, click the Set Water Distance button.
   11.A Water Distance Screen will appear. A default set of numbers will be shown.
      You can change the distance and adjustment factor by clicking in the
      appropriate field.
   12.To add more fields, Click on the Add New Row button and enter the distance
      in feet where adjustments to grazing behavior will take effect.
GSAT Basic User’s Guide                                                       page 28
   13.Once you have your water distances and adjustment factors edited as
      needed, click OK.
   14. Note: A default set of water distances is provided. User should change these
      distances to match the local region.
   15.Click on Calc Water Layer button to calculate the Water Layer. This will
      automatically create the water distance circles for the water layer.
   16.Click on the Water Distribution button on the Left side of the screen.
   17.This also creates new response units. Therefore you must go back to the
      response unit layer and click the Calc Rsp Unit Layer button again to
      calculate the new units.
   18.This will be noticed on the Grazed Inventory Report on Available AUMs and
      Potential AUMs. This will aid in the planning process on where and how many
      water developments need to be added to facilitate prescribed grazing
      distribution.
   19.Note: Slivers will once again be developed along fence lines or Ecological site
      lines. These will show up as having “0” acres. You can delete these slivers
      by selecting the row on the spreadsheet and clicking the Delete Selected
      Features button.
   20.Once you have completed editing, click the Save button at the top of the
      GSAT Screen.

Chapter 4.2 - Adjustments Layer
   The Adjustments Layer allows you to create areas to adjust for lower harvest
   efficiency levels. For instance, an area with a steep slope may be grazed 70%
   less than a flat area. Another example, shown below, is a cedar stand that only
   has 20% of the available forage as the rest of the area surrounding it.
   1. Click the Adjustments button from the Layers section at the left side of the
      screen.
   2. Click the Draw icon to begin setting your adjustments.
   3. Go to the map and cross hairs will appear. Click once to begin your line, click
      again at each turning point. When you are near the end, double click and the
      lines will snap together giving you a polygon. Repeat for additional areas that
      need adjusting.
   4. Click on Edit Feature button, an Adjustment window will appear. Enter a
      description and an adjustment factor for each adjustment area that was
      created. The adjustment factor is entered as a whole number, so an 80%
      reduction would be 20% usable forage as in the case noted above.
   5. Once you have completed the adjustment layer, you will need to return to the
      response unit layer and click the Calc Rsp Unit Layer again to calculate the
      newly added units.
   6. Note: It is possible that slivers will be created for this new Response Unit
      Layer and they can be deleted by selecting the rows on the spreadsheet with
      “0” acres and clicking the Delete Selected Features button.
   7. Once you have all of your adjustments edited to your satisfaction, click the
      Save button at the top of the GSAT screen.
This completes the Data Entry section for GSAT. You may go back at any time and
edit or change the data on the spreadsheets to build scenarios for your client. When

Chapter 5 - Reports and Graphs
Check the reports and graphs frequently; they are automatically updated and change
as you change components of the supply or demand. There are several types to
meet your client’s needs.

Chapter 5.1 - Reports
The Reports tab has seven sub—tabs to choose from and you have the ability to
select the output in AUs, AUMs or Tons just as in the Graphs section. The reports
available are:
          1. Total Balance
          2. Production Summary
          3. Grazed Forage Inventory
          4. Grazed Forage Balance
          5. Roughage Summary
          6. Roughage Balance
          7. Herds Summary
The Production Summary, roughage summary and Herds Summary are spreadsheets
by month of the resources on the ranch that are printable and savable. The
Production Summary is a spreadsheet calculated from data input of the grazable
forage on the client’s ranch. The roughage summary is a spreadsheet of the
roughage table that was compiled in client inventory section. The Herds Summary is
a spread sheet identifying the herds that are grazing on the ranch broken down by
each herd and animal class within the herd.
The remaining reports add have the calculations of the forage/roughage supply and
the animal demands reported by month. The Total Balance report is a spreadsheet
depicting the entire supplies and demands throughout the year. The Grazed Forage
Balance and the Roughage Balance are spreadsheet that single out each supply and
demand. The Grazed Forage Inventory, as shown in the picture below, breaks down
the ranch by management unit or fields.
Within each management unit is the response unit and ecological site or forage
suitability group associated with it. These were calculated in the Forage section
when you calculated the response units. For each of the new response units the
acres, yield, Adjustment factor, Stocking Rate, Potential AUM, and Available AUM are
shown and a subtotal for each management unit are depicted. The potential AUMs
are what the site could actually produce when everything is as good as could be and
the adjustment factor is 100%. The available AUMs are what is actually being
consumed according to the adjustment factor that has been assigned to that
particular area. Hence your concentrated planning efforts will take effect in these
areas.
Note: Reports can be saved in a number of formats; one of the most useful is the
single or multi sheet MS Excel format. You can save a report to Excel and then
create your own custom reports, add graphs, text, etc. to meet the needs of the
client.

Chapter 5.2 - Graphs
The graphs tabs are set up with several sub—tabs to allow you to get the information
that you desire for a client. Under the Graph tab there are 6 different categories to
choose from. These are:
          1. Forage Balance
          2. Forage Supply and Demand
          3. Roughage Supply and Demand
          4. Total Forage and Roughage Accumulated
          5. Total Forage Accumulated
          6. Total Roughage Accumulated
You have the option of selecting whether you want a line or a bar graph, and you can
select the output units in AUs, AUMs, or Tons. This is strictly a user’s or client’s
preference. Each graph can be printed to add to the client’s plan by clicking the
Print button. You can save the graphs to the customers file by clicking the Save
button. A Save window will appear for user to navigate to the desired folder to store
this information. Saving in the Customer’s CST file in the GSAT folder will be
advantageous.
Note: you can change the appearance of graphs by right-clicking in the title area
and changing colors, fonts, sizes, and even the graph title.

Grazing system A specialization of grazing management that defines systematically
recurring periods of grazing and deferment for two or more pastures or management
units. Descriptive common names, such as Merrill, Hormay, or South African
switchback, may be used. However, the first usage of a grazing system name in a
publication should be followed by a description using a standard format. This format
shall consist of a numerical description in the following prescribed order: the number
of pastures (or units), number of herds, length of grazing periods, length of
deferment periods for any given unit in the system followed by an abbreviation of the
unit of time used. Examples:
• Merrill system (4-3;12: 4 mo.) is a grazing system with 4 pastures, 3 herds of
livestock, a 12-month grazing period, and a 4-month deferment period.
• South African switchback (2-1;3:3,6:3,3:6 mo.) is a grazing system with 2
pastures, 1 herd, and a grazing schedule of 3 months grazing, 3 months deferment,
6 months grazing, 3 months deferment, 3 months grazing, 6 months deferment.
• High intensity, low frequency (HILF) (14-1; 12:156 da.) A grazing system

material from which it was derived in many physical, chemical, biological, and
morphological properties and characteristics.
Soil map unit A map unit is a collection of soil areas or miscellaneous areas
delineated in a soil survey. They may encompass one or more kinds of soil or one or
more kinds of soil and a miscellaneous area, such as rock outcrop. They are
identified by a unique map symbol in a survey area. There are four kinds of map
units; consociations, complexes, associations, and undifferentiated groups.

Stocking rate The number of specific kinds and classes of animals grazing or
utilizing a unit of land for a specific period of time. May be expressed as animals per
acre, hectare, or section, or the reciprocal (area of land/animal). When dual use is
practiced (e.g., cattle and sheep), stocking rate is often expressed as animal units
per unit of land or the reciprocal.
Stockpiling Allowing standing forage to accumulate for grazing at a later period,
often for fall and winter grazing after dormancy.
Stock water development Development of a new or improved source of stock
water supply, such as well, spring, or pond, together with storage and delivery
system.
Strip grazing Confining grazing animals to a specified portion of a grazing area for a

rangeland.
Sustained yield Production of specified resources or commodities at a given rate for
a designated unit of time.
Tame pasture Implies the forages growing on the land unit have been purposely
cultivated by people as opposed to being wild growth of random origin. In permanent
pastures it is often a combination of the two mechanisms and, therefore, a rather
subjective and imprecise term. Synonymous with improved pasture.

Ungulate A hoofed animal, including ruminants, but also horses, tapirs, elephants,
rhinoceroses, and swine.
Unsuitable range Range that has no potential value for, or which should not be
used for, a specific use because of permanent physical or biological restrictions.
When unsuitable range is identified, the identification must specify what use or uses
are unsuitable (e.g., unsuitable cattle range).
Usable forage The portion of the standing forage crop that can be grazed off
without damage to the forage plants. It varies by plant species, season of use, and
companion plant species that need favoring to promote their continued existence in
the stand. The pasture management section refers to it also as available forage.
Use (1) The proportion of current year's forage production that is consumed or
destroyed by grazing animals. May refer either to a single species or to the
vegetation as a whole. Syn., degree of use. (2) Utilization of land for a purpose, such
as grazing, bedding, shelter, trailing, watering, watershed, recreation, forestry, and
wildlife habitat.
Utilization Syn., use.
Variable rotational stocking A stocking method that adjusts the recovery period
between grazing periods to the variable growth rate of the forage species being
grazed. It attempts to offer a uniform forage allowance to livestock each day of the
grazing season through the allocation of forage by sequential grazing of paddocks.
Variable stocking The practice of varying the stocking rate through the plant
growing season with the objective of utilizing forage at a rate similar to its growth
rate. This can be done by either varying the number of animals on a set acreage or
varying the acreage offered to a set number of animals.
Water gap (1) A specially constructed fence across a drainage. The fence is easily
