Would you review the plan and e-mail us a concurrence (or questions or suggested <br />modifications)? <br />Keenesburg Mine <br />2010 Phase III Final Bond Release Sampling Year 2 (this is the same sampling plan as last year) <br />1998 Reclamation Areas (Areas 2, 7, 10, 15, 16) <br />• Total Vegetation Cover (by species) to sample adequacy with a minimum of 15 samples <br />• Total Herbaceous Production to sample adequacy with a minimum of 15 samples <br />• Species composition calculated from cover data <br />• Proportional representation of areas by acreage <br />1999 Reclamation Areas (Areas 5, 9) <br />• Total Vegetation Cover (by species) to sample adequacy with a minimum of 15 samples <br />• Total Herbaceous Production to sample adequacy with a minimum of 15 samples <br />• Species composition calculated from cover data <br />• Proportional representation of areas by acreage <br />2000 Reclamation Areas (Areas 6,19) <br />• Total Vegetation Cover (by species) to sample adequacy with a minimum of 15 samples <br />• Total Herbaceous Production to sample adequacy with a minimum of 15 samples <br />• Species composition calculated from cover data <br />• Proportional representation of areas by acreage <br />Monitoring in Area 30 <br />• Total Vegetation Cover (by species) with 10 samples <br />• Total Herbaceous Production with 15 samples <br />• Species composition calculated from cover data <br />The sample methods will be the same as we have used in the past, an optical point frame for cover with 25 meter <br />transects and data points taken each meter on opposite sides of the transect. Total herbaceous production will be by the <br />harvest method using 0.5 square meter plots. All transects and plots are randomly located within the reclamation areas. <br />We are proposing not to monitor/sample Area 25 this year. While it looks like there are some more perennial grasses <br />around the edges of Area 25, the vast majority of the parcel is cheatgrass. Dan has mowed the parcel to try and reduce <br />annual growth, however there has been no significant change is species composition so far this growing season.
