Vegetation Monitoring for Phase III Bond Release HG Mine, Routt <br />Co., CO <br />INTRODUCTION <br />Eour small areas will be sampled in July 2004 to assess the adequacy of revegetation. <br />Three of these areas are shrub enclosure sites that total 7.5 acres. The fourth area is a <br />small site associated with a repaired highwall slope that covers slightly over one acre <br />Methods to be used are set forth below. Sampling will be conducted by ESCO <br />Associates Inc. <br />METHODS <br />Sample Locations and Number <br />Each of the three shrub enclosure areas will have five randomly located <br />cover/production/shrub density samples and an additional five shrub density-only sites. <br />The very small highwall repair site will have three randomly located <br />cover/production/shrub density sample transects placed in it. <br />Cover Sampling <br />Cover data will be collected along 50 m transects using a point intercept method in <br />which data are recorded as interceptions of a point with plant species, litter, standing <br />dead plant material, soil or rock. Intercepted plant matter produced during the current <br />year and still standing are tallied by species. Litter will be considered to be any organic <br />material that had fallen, or had begun to fall to the soil surface. Standing dead will be <br />any dead plant material that was produced in previous years but which is still standing <br />and had not lodged or broken off to become litter. Inorganic materials greater than 1 cm <br />in diameter will be considered rock. The cover sampling points will be optically projected <br />using aCover-Point Optical Point Projection Device developed by ESCO Associates. <br />The 50 m transects will be randomly located and oriented in the reclaimed and reference <br />areas. Apre-determined number of points (100) will be collected at each transect and <br />distributed evenly along the transect. A pair of points will be collected at specified (one- <br />meter) intervals with points sampled on opposite sides of the transect 0.5 m from the <br />transect. <br />6/27/04 1 ESCO Associates Inc. <br />
