Abstract:
  The vegetation mapping effort consisted of digitizing vegetation polygons using 1950's, 1976-1977, and 2001 aerial imagery in a GIS environment. The polygons are digitized at a scale of approximately 1:7,500, with a minimum mapping unit of approximately 10 acres. The goal of the delineation was to capture areas of similar vegetation structure as they appeared on the aerial imagery, while maintaining a consistent scale. This was notably challenging with the 1950 images due to locally poor resolution of the riparian areas. The 1977 and 2001 imagery has significantly better resolution.
  Six vegetation classes were developed for the mapping effort. These classes were determined to be the highest level of detail permitted by all suites of imagery. For the purposes of this study, only the three woody vegetation classes are summarized as "riparian". The Herbaceous, Channel and Outside of Floodplain classes were not summarized or analyzed by this study.
  It should be noted that, due to the remote nature of the mapping, the vegetation delineation is subject to interpretation errors. While polygon boundaries may be of good accuracy, the vegetation class assigned to them is in many places limited by the resolution of the photography. Efforts were made to verify the spatial and attribute accuracy of vegetation polygons, including checking them against field data collected by the avian study that was recently completed by MSU as part of the overall Yellowstone River Cumulative Effects Study.
  Vegetation Class Codes:
  Herbaceous = H
  Shrub = S
  Open Timber = TO
  Closed Timber = TC
  Channel = Ch
  Outside of inundatin boundary or imagery extents = OUT
Purpose:
  Riparian vegetation boundaries mapped from 2001 color infrared imagery. Approximate mapping scale is 1:7.500. Minimum Mapping Unit is approximately 10 acres. Some areas smaller than 10 acres were mapped if they were distinct and identifiable in the imagery. See the accompanying report for complete details on the mapping process.
