<br />Vegetatlon Measurements /or Bond Release: New Horlmn Mine NH1 10Aae Sr'te and Revemnce Area <br />516.51b/acre; the reclamation standard is equal to g0% of the mean, or 466.71b/acre. Mean <br />production at the NH1 10.acra sife was 2,060.91b(acre. Because sample adequacy was not <br />reached for production sampling at NH1, the reverse null hypothesis test was used to compare <br />the NH1 mean to the reclamation standard. Table 5 shows the input values and the calculated <br />t-sfetistic, which greatly exceeded the table t-value. qs a consequence, the null hypothesis was <br />rejected, and revegetation for production is deemed complete. - <br />5.0 CONCLUSIONS <br />Vegetation sampling at the NH1 10.acre site and the Dryland Pasture Reference Area in August <br />and eady September 2005 showed that mean cover of live perennial vegetation and mean <br />herbaceous production at the NH1 10-acre site exceed the reclamation sfandards (90% of the <br />reference area means). As a result, revegetation for cover and production at the NHt 10-aae <br />site are deemed successful for bond release. <br />6.0 PERSONNEL QUALIFICATIONS <br />Bio-Logic Environmental is a natural resources consulting firm in Montrose, Colorado, since <br />1992 providing natural resources inventory, research, and management services to government <br />agencies and the private sector. <br />Project Manager and Field Leader for this project was Steve Boyle, Senior Biologist at 610. <br />logic. Mr. Boyle has a B.A. degree in Biology (Indiana University), an M.S. degree in Wildlife <br />Biology (Colorado State University), and 26 years of professional experience in wildlife <br />• research, plant and animal inventory, and conservation analysis. He is performing coal mine <br />bond release vegetation studies for the West Elk Mine, Gunnison County, Colorado, and related <br />environmental compliance work. He has recently led field teams conducting inventories of rare <br />plants and noxious weeds for numerous gas pipeline and transmission line projects in Colorado, <br />Utah, and Nevada. He has been Principal Investigafor for funded research on wildlife <br />populations and vegetation successional patterns at U.S. Army Dugway Proving Ground, Utah, <br />is an invited peer reviewer of the Colorado GAP Analysis Project and the USGS Southwest <br />Regional GAP Analysis Project, and co-authored the Colorado Breeding Bird Atlas. Mr. Boyle <br />was formerly a Research Associate at the Colorado Cooperative Wildlife Research Unit, <br />Colorado State University; Research Technician at the U.S. Fish and Wildlife Service, Fort <br />Collins; District Wildlife Manager for the Colorado Division of Wildlife; Senior Wild!rfe Biologist at <br />AGEISS Environmental, Denver; and a Research Associate of the Royal Australasian <br />Ornithologists' Union, Christmas Island, Australia. <br />Field Biologists for this project were Jim Le Fewe and Ccen Dexter. Mr. Le Fevre, WilClife <br />Biologist at 810-Log(c Environmental since April 2005, has a BS degree in Wildlife Biology and <br />over 15 years of field experience in western Coorado conducting wildlife surveys, habitat <br />evaluations, and plant species identification and measurement. Coen DeMar is a consulting <br />biologist and ornithologist with over 10 years of professional experience in Colorado and nearby <br />states conducting bird surveys, noxious weed inventories, and plant association mapping. <br />B/0.LOgre Envlronmanhr <br />September 2005 <br /> <br />14 <br />
