Moxa Arch Vegetation Classes

This dataset was developed for the purpose of wildlife habitat modeling
contributing to the cumulative impacts assessment portion of a Environmental
Impact Statement for the Moxa Arch oil and gas development area.

A vegetation classification was derived from a supervised classification of
EOSAT Landsat Thematic Mapper (25 meter data from a scene recorded on June 30,
1994) for the Moxa Arch area of southwestern Wyoming. USGS 7.5 minute
quadrangles covered by the vegetation map include: Church Butte, Church Butte
NW, Cow Hollow Creek, Fontenelle, Fontenelle SE, Granger, McCullen Bluff,
Moxa, Sevenmile Gulch, Shute Creek Lake,Verne, and Whisky Buttes.

Spectral band ratioing of the Landsat Thematic Mapper was used to distinguish
between the various vegetation types. In all, eleven types were
distinguishable: low density sagebrush, high density sagebrush,
greasewood/mixed shrub, saltbush/playa, playa/barren, riparian scrub/shrub,
riparian forest, wet meadow, industrial, agricultural wet meadow, and water.

V. Herren, BLM Kemmerer Resource Area Office, conducted ground truthing of
the vegetation classifications.
