1989 Coal Basin Annual Bond Tracking - Vegetation <br /> Sampling <br /> Cover sampling was done on the old refuse pile on August 8, 1989. Ten 50m <br /> transects were run on the ortion of the pile which was seeded before 1986. <br /> Ten observations were made at each of 5 points on each transect with an <br /> optical point frame. <br /> Results <br /> Results are summarized in he attached tables. Vegetative cover averaged <br /> 24.2% and woody plant dens ty averaged 267 stems per acre. <br /> Comments <br /> Data for areas seeded from)977 through 1985 is combined since the mine does <br /> not know which areas were seeded when. There is quite a bit of difference <br /> between vegetative cover on some of the areas of the refuse pile. <br /> The cover success standa 4 for this area is based on reference area data, <br /> which was 60.8% during pre 4ine sampling. Present vegetative cover is 56% of <br /> the reference area cover d�ring the pre-mine year. <br /> The woody plant density su cess standard for this area is 100 trees and 500 <br /> shrubs per acre. There ar approximately half this number of shrubs present <br /> (267/acre) and virtually n trees (8 junipers/acre) . <br /> 9804F/scg <br />
