  Who are we?
We are the Idaho Conservation
Data Center


Housed within the Idaho
Department of Fish & Game.


Member of a national network of
Natural Heritage Programs called
NatureServe. Member programs
exist in all 50 states.
  Conservation Data Center
          Idaho Fish and Game

  The Idaho Conservation Data
    Center collects, analyzes,
   maintains, and disseminates
 scientific information necessary
     for the management and
conservation of Idaho’s biological
              diversity.
              Data Sources
Receive data from a variety of sources:

•   Herbaria/Museum Specimens
•   Rare Plant / Animal Observation Forms
•   Published Scientific Journals
•   Unpublished resources
    – Academia
    – Botanist / Biologist field notes
 What is an Element Occurrence?



• An Element Occurrence (EO) is an area of
land and/or water in which a species or
natural community is, or was present.

• An EO should have practical conservation
value for the species.
  Element Occurrence Record
            (EOR)


• data management tool
• has both spatial and tabular
  components including a mappable
  feature and associated data
EO Representations (EORep)


• Are polygons
• Incorporate Locational Uncertainty
• Developed from Source Features (points,
  lines, and/or polygons)
• Can be comprised of multiple features

     Review of Terminology
Element Occurrence (EO) – The area on the
ground that represents what you actually
saw.

Element Occurrence Record (EOR) – The data
record of what you saw.

Element Occurrence Representation (EORep)
– The spatial representation (in polygon form)
of what you saw.
                Data Processing
•   Mapping each location accurately and entering data from a variety
    of sources can be challenging.
              BIOTICS
     CDC data management tool

• Mapper: Enables us to “map”
  locations digitally using ArcView 3.2
• Tracker: Relational database using
  Oracle
• Reporting using Crystal Reports.

Spatial Linework

    •   Whoa, that looks different!
    •   We want points!
    •   This is a mess!
    •   How am I going to display this?
     Why the data look this way

• EOReps are polygons to incorporate
  Locational Uncertainty.
• Locational uncertainty is affected by:
  – survey techniques and equipment

  – expertise of collector

  – amount and type of information
    collected
   High Locational Uncertainty




• EO can occur anywhere within the buffered circle.
• Vague location information provided.
 Medium Locational Uncertainty




As the quality of the data increases the Locational
              Uncertainty decreases.
 Low Locational Uncertainty




Very precise data enable precise mapping
     Why is this so important?



             Project Area




• Querying points returns only 1 EO.
• Querying polygons indicates that possibly
  3 EO’s are present.
Displaying EO Information
  Use the legend to define by unique values.
