39 from the 2007 sampling year fell within reclamation blocks not included in the <br />Phase II Bond Release application. Please either update the 2006 and 2007 <br />vegetation monitoring reports to eliminate data from the reclamation blocks <br />not included in the Partial Phase II Bond Release SL-04 application or please <br />remove the 2006 and 2007 vegetation monitoring reports from the SL-04 <br />application. If the data for the above referenced parcels is removed from the <br />2006 and 2007 vegetation monitoring reports, all of the cover and sample <br />adequacy calculations will need to be redone. Please note that reclamation <br />blocks S16010 and S16014 were only sampled in 2006 and 2007. The <br />elimination of the 2006 and 2007 vegetation monitoring reports from the SL- <br />04 application will also require the removal of these reclamation blocks from <br />the application. <br />2. In the 2009 vegetation monitoring report, Colowyo has included reclamation <br />block WP001 in the sample data. Reclamation block WP001 is not included in <br />the Partial Phase II Bond Release SL-04 application (it was Phase II Released on <br />15 August 2001 with SL-03). Colowyo will need to remove all monitoring data <br />from reclamation block WP001 from the 2009 vegetation monitoring report. <br />Please remove all reference to and data from reclamation block WP001 from <br />the 2009 vegetation monitoring report. Please redo all cover and sample <br />adequacy calculations as necessary. Please resubmit the 2009 vegetation <br />monitoring report for the Division's review. <br />3. Based on a review of Exhibit 2 - Phase II Bond Release and Map I of the 2009 <br />vegetation monitoring report, it appears as though transect 37 may be outside <br />(east of) reclamation block WP004 and, therefore, outside of the requested Phase <br />II Bond Release area. Please review the location of transect 37 from the 2009 <br />revegetation monitoring report and verify whether it is, in fact, inside the <br />Partial Phase II Bond Release SL-04 area. If transect 37 is outside of the SL- <br />04 area, please remove it from the 2009 revegetation monitoring report. <br />Please redo all cover and sample adequacy calculations as necessary. <br />4. In each vegetation monitoring report, Colowyo provides a map of the transect <br />locations (starting points) that were sampled for that year. Each of these sample <br />location "dots" has a very large scale. Based on the map scale, each of these dots <br />is approximately 225 feet in diameter (or approximately 0.91 acres). This large <br />size makes it difficult, in some cases, to determine which reclamation block a <br />sample transect is located in (see question 3 above). The Division understands <br />that a larger "dot" is easier to see on the map, but the large size of these dots has <br />added a level of confusion. Please reprint the transect location maps in the <br />vegetation monitoring reports using a smaller "dot" size for the transect <br />locations and resubmit them for the Division's review.
