~_ <br />subset of 15 points was selected as end points for cover transects by randomly <br />selecting two (short litres) or more (long lines) points along each of the north-south <br />gridlines. Transects extended from each end point along a randonily determined <br />azimuth. <br />The reference area was fenced in the spring of 1993. For the 1993 vegetation <br />sampling, only the south half (-1.5 acres) of the reference area, which has been <br />ungrazed, was sanrpled. The Division of Minerals and Geology had a <br />' representative in the field who concurred with this decision. It is intended that <br />future sampling of this reference azea will entail the entire azea. <br />i For tine reference azea sampling, a compass was spun to provide random direction <br />and a random number generator (on a calculator) was used to select distance from <br />an arbitrarily selected initial sampling location. The point at the distance and <br />direction from the initial sampling location became the second sampling location. <br />The procedure was repeated to select each subsequent sample location. <br />Cover and production. Herbaceous production was determined by harvesting <br />current year's herbaceous vegetation from 0.5-meter-squaze quadrats. Harvested <br />material was separated by life form (grasses and forbs) and weighed for initial <br />deternunation of sample adequacy. Samples were later oven dried and weighed <br />again. Production data and sample adequacy given in this report are based on <br />oven-dry weights. <br />I For vegetation cover, a transect method has been adopted in lieu of the quadrat <br />~ method used in the original vegetation baseline inventory. This method is more in <br />conformance with the Division's technical guideline for vegetation sampling. The <br />Division approved this change. Vegetation cover transects were located in <br />~ conjunction with production quadrats. Transects were 5 meters long. Azimuths <br />from the point of beginning of each transect were randomly deternined. An <br />~ "optical bar" was used to determine "hits" at 10-centimeter intervals. The optical <br />bar is a franre holding ten specially designed non-magnifying scopes. The optical <br />baz is mounted on a tripod and is used essentially like a point frame. The scopes <br />are aimed vertically toward the ground. The intersection of the cross-hairs in each <br />telescope defines a "point" or hit. Each hit is recorded as a vegetation species, <br />rock, litter or bare ground. Each transect comprised 50 hits. <br />Results <br />Results of the 1993 vegetation sampling at the Meadows No. 1 mine are shown in <br />the accorrrparrying tables.
