METHODS <br /> <br />in field reconnaissance was performed in May, ].9'19 to determine the boon- <br />Cary of the revegetation plot study area, estimate sampling intensity <br />necessary to accomrodate observed natural vari.aibility in vegetation cover <br />and production and fulfill sampling adequacy re3uirements. The revege-- <br />tation plot was randomly sampled to gather production, Dover anti frequency <br />data for the 1979 gmwing season. Native mixe~ri brush and upland sagebrush <br />vegetation types were also sampled during the same season in conjunction <br />rtith baseline vegetation studies conducted at Seneca II Mine. Data <br />frcan revegetation areas are discussed using data from native areas as <br />a comparative basis to provide some indication ~of the degree to which <br />reclamation goals have been achieved (i.e., replacarent of pre-disturU3nce <br />vegetative cover and production). All native area data are presented .in <br />the vegetation baseline report (Mariah Associates, 1980) for Seneca II Mine. <br />b;aPPING <br />Recent aerial photographs taken at a scale of 1" = 400' (May, 1978) • <br />here used tA~delineate the areal extent of the' revegetation plot and to <br />cepict sample point locations. Sample point :Locations were verified <br />during ground truth efforts performed in conjunction with field sampling <br />activities. Acreage of the plot was determinE~cl by standard polar plani- <br />refer tecluiiques. To ensure accurate acreage determination, the plot <br />was measured until measurements varied by less than 58 and the resulting <br />a•,rerage used to ccxcquute acreage. <br />SAAfPLE SITE LiOCATION <br />A random method was used to locate all production, cover and frequency <br />sampling points. This method entailed overla_ling a grid system on the <br />aerial photograph displaying the revegetation plot. A random numbers <br />table was then used to determine grid coordinates and thus sampling <br />points. <br />-4- /^ <br />
