• the proposed regulation changes issued on March 27, 2003 entitled "Revegetatwn, Land Use, <br />Wildlife and Alluvial Palley Floors" and formally adopted September 14, 2005 by the Colorado <br />Division of Minerals and Geology (DMG now called the Colorado Division of Reclamation, <br />Mining and Safety RMS) and corresponding documents were used with respect to sample <br />adequacy calculations and proposed statistical comparisons. The con•esponding vegetation maps <br />showing the locations of the two reference areas sampled in connection with this sampling effort <br />are found on Map 18, Ken Mine Area Vegetation. The specific limits of the specific <br />reclamation units sampled were taken from the 2004 Annual Reclamation Report Maps for the <br />Marc Mine Area. <br />Prior to commencing the 2006 field sampling and during the preparation of this report, the <br />Permit monitoring requirements were reviewed and discussed with Mr. Patterson and Mr. Jerry <br />Nettleton, formerly with Montgomery, Watson Harza Inc. and Ms. Janet Binns of the RMS <br />regarding the proposed sampling methods and data analysis methods to be used. Agreement on <br />the sampling methodology used in this evaluation as well as permission to use the recently <br />adopted program amendments was obtained from the RMS prior to initiating field sampling. In <br />this evaluation, the vegetation parameters of production, plant cover, species diversity and shrub <br />density were sampled. These data were then utilized to evaluate the successfulness of <br />revegetation efforts with respect to cover, forage production, species diversity, and shrub <br />density. <br />Transact Locations. To ensure that all of the areas within each corresponding reclamation block <br />. and reference area sampled, had an equal chance of being sampled, each proposed sample azea <br />was treated as a sample unit and a totally randomized sampling effort was implemented. <br />Utilizing the original vegetation maps, showing the specific reference area locations and 2004 <br />reclamation maps prepazed by Kerr and our GPS unit, the extreme north, south, east and west <br />boundaries of each site sampled were converted to the 1927 Colorado State Plan Northern Zone <br />(NAD 27) coordinate system. The interval used in the state plan coordinate system is based on <br />foot increments. Given the typical real-time accuracy of this GPS unit of plus or minus 18 <br />inches, all of the transact locations were field located at a sub-meter accuracy. <br />Once the boundaries of the reclaimed area or reference area were identified, then using a <br />specially prepared computer program which generates random coordinates, the potential transact <br />location coordinates were identified. These coordinates were then entered into the GPS unit and <br />the transact location starting points were mazked in the field. At each transact location starting <br />point, the transact direction was determined by selecting a random direction based on the degrees <br />of the compass (0 to 360.Once the transact orientation was determined, then the 50-meter tape <br />was laid out across the site. All transecis were kept within the sample unit boundaries. In <br />situations where the transec:t placement resulted in the traosect alignment crossing a sample unit <br />boundary, the transact line was backed up for that portion of which crossed the boundary line <br />180 degrees. Where the 50-meter tape could not be placed within a narrow reclaimed area due to <br />boundary constraints, then the transact line was changed 90 degrees at the point where the <br />boundary line was crossed to ensure that the entire transact alignment was located within the <br />area to be sampled. <br />n <br />lJ <br />
