comparison area is approximately 1.3 acres in size. The vegetation immediately surrounding the comparison area is predominately oak thickets, thus any increase in the size of the area as delineated would not be useful in characterizing the non-woody vegetation. The comparison area in the river terrace type is located in an area between the two mine portals between the hiway and the North Fork of the Gunnison River(see attached map). It is characterized by cottonwoods, birch and a rich diversity of native understory species typical of riparian vegetation types. Other river terrace types visited had either been disturbed from mining activities or showed evidence of past grazing use with an abundance of weedy annual and perennial species. The area selected is most representative of the potential for the native cover and species diversity on the disturbed river terrace areas. The site selected as a comparison area in the river terrace type is approximately 1.5 acres. Again, an increase in the size of the area would only incorporate areas non-typical of, the river terrace type and would not provide representative vegetation data. PROPOSED SAMPLING PROCEDURES Sampling is to be performed during June of 1984. The river terrace type will be sampleA after the upland oakbrush type to better facilitate sampling during peak production. The precipitation in the vicinity of the Hawk's Nest Mine was approximately 19 inches in 1983, well shove the normal of 14.69 inches per year(National Oceanographic and Atmospheric Administration, Climatological Data, Jan. 1983-Dec. 1983, Vol 88 Nos. 1-12.). Sampling will, therefore, only occur during June of 1984 and data collected will be used directly for comparison of revegetation success. Field sampling will include the collection of data on total cover by species, excluding tree species in the river terrace type, and herbaceous productivity by life form. Woody plant density will not be collected, since a woody plant density standard will not be set for the area. Species diversity will be determined from the cover data collected. Vegetation cover will be measured from point samples with a point-frequency frame along a 50 meter line transect as outlined in Guidline No. 2 of the Wyoming Department of Environmental Quality Land Quality Division. Additional cover and/or density transects will be sampled until sampling adequacy is met, also following the format described in the aforementioned Guideline No. 2. Each cover transect will be randomly located by superimposing a grid over the comparison area and randomly selecting a grid coordinate to serve as the starting point of the transect. The beginning of the transect will be located in the field by pacing. At each 1 meter point along the transect, the first interception of the needle projected vertically downward through the frame will be recorded. Consequently, a total of 50 points per transect will be sampled. If additional species
