               Pilot Season – 2008
              Protocol
Clarifications & Recommendations
             Plant Groups
• Foliar (vertically-projected cover) cover
  used rather than canopy cover to select an
  initial life-form class (e.g. Herbaceous
  (100s), Low Shrub (200s), Tall Shrub
  (300s) or Tall Shrub Only (400s))
• Native trees on the invasives list were
  counted as native in the plot classification
  scheme (TNC)
• Others interested in adding dominant
  natives at the plot level? If so, add as
  “optional” component of Option B?)
       Species Identification
• More training & resources needed!
• Over-reporting of Pasque flower (TNC)
• Milkweed confusion (TNC)
• Poa pratensis vs. P. compressa (now
  lumped as POACPX)
• Dead vegetation (not considered by TNC
  in presence/absence)
• Tier 1 only used earlier in field season,
  Tier 2 as confidence increased
         Transect Rejection
• Some previously-established transects
  crossed transition zones in 2008, and
  were not thrown out (TNC)
• See updated “rejection criteria” in new
  protocol format

Data Base
                   Reports

• Average VOR report needed
• Transect level data (VOR, system type, indicator
  species, etc.) not needed on each page of
  transect report – just transect name and date are
  fine.
• Alphabetize invasives within plots on transect
  reports to make error-checks easier?
• Indicator species sometimes cut off from
  transect details reports (if >4 species two far
  right ones cut off)
           Additional Fields
• Version of monitoring protocol used
• Treatment groups or dates of treatments
• Possible to select Option B, but also be
  able to use *just* Tier 1 species without
  confusing anyone?
• “Notes” field was added during 2008 field
  season, but tied to a transect rather than
  to a monitoring event.
   Organization/Data cleanup?
• Rearrange order of drop-down boxes so 5
  most common weeds at top?
• What if data missing, especially with litter
  or VOR? Need to have an N/A?
• When is it necessary to do set-up?
Database Comments for Group
• If data for a transect are incomplete, let
  Sara know it should be excluded from the
  analysis
• Data entry tips:
  – Can start typing instead of drop-downs
  – Tips for data quality checks
