Introduction <br />0 At the request of Trapper Mining Inc. (Trapper), the second year of Phase III final bond release <br />revegetation sampling was conducted on Rangeland Reclamation Block AD&H-AB which was <br />reclaimed between 1996 and 1998 and contains approximately 305.2 acres. The locations of the <br />specific reclamation blocks sampled in this evaluation are depicted on the enclosed maps. This <br />revegetation monitoring effort was prepared with the intention of satisfying the second year of <br />the final two years of the Phase III monitoring requirement of the final bond release <br />revegetation sampling requirements for Rangeland Reclamation Block AD&H-AB. <br />Mr. Kent Crofts of DdE, who has conducted numerous other previous vegetation sampling <br />efforts at the Trapper Mme, adjacent Empire Energy Mine and numerous other sites in <br />northwest Colorado in the past 31 years, directly supervised and participated in all field <br />investigations. Assisting in this sampling effort was Mr. Jesse Petersen who acted as field GPS <br />technician and was responsible for determining all of the transect locations using the Trimble <br />Model Geo XH Global Positioning System. Both individuals assisted with the field sampling <br />and data analysis. <br />Methods <br />Maps, in both electronic and hard paper format of the reclamation areas sampled in this <br />revegetation monitoring effort were supplied by Mr. Forrest Luke, Environmental Manager of <br />Trapper Mining Inc., who delineated to the field crews, the exact extent of the reclamation <br />efforts at the Trapper Mine. The specific sampling methodologies used in this evaluation are <br />those found in the Division's "Guidelines with Land Use and Vegetation Requirements of the <br />• Colorado Mined Land Reclamation Board for Coal Mining" issued in June of 1988 and the <br />"Guidelines Regarding Selected Coal Mine Bond Release Issues" issued April 18, 1995. In <br />addition to these guidelines, the revised regulation changes contained in the 14 March 2003 <br />Colorado Division of Minerals and Geology (DMG) document entitled "Revegetation, Land <br />Use, Wildlife and Alluvial Valley Floors" -,Proposed Colorado Program Amendments, which <br />have been adopted as Section 4.15.11, Rvvegetation Sampling Methods and Statistical <br />Demonstrations for Revegetation Success was used with respect to statistical comparisons. <br />Prior to commencing the field sampling and during the preparation of this report, the Permit <br />monitoring requirements were examined and discussed with Mr. Luke regarding the proposed <br />sampling methods and data analysis methods to be used. Agreement on the sampling <br />methodology used in this evaluation as well as permission to use the proposed program <br />amendments was obtained by Trapper from the DMG prior to initiating field sampling and <br />approved by the Division for use at the Trapper Mine for this sampling effort. In this evaluation, <br />the vegetation parameters of plant cover, production, species diversity and shrub density were <br />sampled. These data were then utilized to evaluate the successfulness of revegetation efforts <br />with respect to these parameters. <br />Transect Locations. To ensure that all of the reclaimed areas within the Reclamation Block <br />sampled had an equal chance of being sampled, the entire reclamation area was treated as a <br />single sample unit and a totally randomized sampling effort was implemented. Utilizing the <br />base map prepared by Trapper, the extreme north, south, east and west boundaries of the <br />reclamation areas being evaluated were identified according to the 1927 Colorado State Plane <br />Northern Zone (NAD 27) coordinate system. The interval used in the state plan coordinate <br />9
