o:;:r< ,~ .~") ( ~.~-) C\l o o Summary SUMMARY The San Luis Proposed Resource Management Plan iden- tifies the future management of BLM -administered lands and subsurface minerals within the San Luis Resource Area in south-central Colorado. The proposed plan is a modified version of the Preferred Alternative presented in the Draft San Luis Resource Management Plan and Environmental Impact Statement (RMP/EIS), published in September 1989. A summary of the proposed plan by affected resource or resource use follows. Fluids Minerals Manage- ment Approximately 259,000 acres (41 percent) of the planning area are open to leasing with standard terms and conditions. (See Mineral Decisions Map in the back of this document.) Approximately 342,000 acres (55 percent) of the planning area are open to leasing with various limitations; e.g., seasonal restrictions. Approximately 17,000 acres (3 percent) of the planning area are open to leasing with a no surface occupancy stipulation. Approximately 3,600 acres (lpercent) of the planning area are closed to leasing. Locatable Minerals Manage- ment Approximately 601,000 acres (97 percent) of the plonning area are open to mineral entry and development. Approximately 17,000 acres (3 percent) of the planning area are withdrawn from mineral entry and development. (See Mineral Decisions Map in the back of this document.) Minerai Materials Manage- ment Approximately 599,000 acres (97 percent) of the planning area are open for disposal of mineral materials. Approximately 22,000 acres (3 percent) of the planning area are closed to disposal of materials. (See Mineral Decisions Map in the back of this document.) 0,. Paleontological Resources A continual effort to provide intensive inventory and protection, interpretation, and management of these resources will be accomplished within the planning area. A public educational fossil interpretative site (a large area near Clayton Cone) will be provided within the planning area. Riparian Resources Manage- ment Good to excellent condition will be maintained on ap- proximately 1,400 acres of riparian vegetation within the planning area. Fair or poor condition will be improved on approximately 400 acres of riparian vegetation, and an ap- proximate 15 acres of poor condition riparian vegetation will remain the same. Approximately 1,400 acres of historic wetlands will be redeveloped, and about 1,400 additional acres of potential riparian vegetation will be inventoried. Livestock Grazing Manage- ment About 32,400 AUMs will be available for domestic livestock grazing on BIM -administered lands within the planning area. Of the estimated potential increase of 11,500 AUMs within the planning area during the next 20 years, about 4,600 AUMs or 40 percent will be made available to live- stock. The remainder will be for support of the ecological base and wildlife, if needed. Wildlife and Fish Habitat Management Waterfowl and shore bird populations on lands ad- ministered by BIM will increase significantly during the next 20 years. About 48,000 AUMs will be available to support the wildlife on BIM-administeredlands. Of the estimated potential increase of 11,500 AUMs within the planning area during the next 20 years, about 6,900 AUMs or 60 percent will be made available to wildlife and support of the ecological base, if needed; the remainder will be available to livestock. Stress on big game will be reduced on approximately 342,000 acres of crucial winter habitat. About 73.5 miles and 180 acres of warm and cold water fisheries habitat will be available. S-l
