<br />iJJ1~88 <br /> <br />use by public and government entities. Disposal of mineral <br />materials would not occur on 4,395 acres within the proposed <br />Rio Grande River Corridor Special Recreation Management <br />Area (SRMA) and 3,300 acres within the WSAs <br />recommended for wilderness designation. This closure would <br />result in a negligible impact because of the low resource <br />potential of this area, its general inaccessibility, long haulage <br />distance to processing centers, and the abundant alternative <br />sites located in the planning area. Total acres closed to <br />minerals materials disposal would be 7,695 (1 percent). <br /> <br />Paleontological Resources <br /> <br />Paleontological resources would be managed only to the <br />extent specified in the Antiquity Act of 1906 and according <br />to general Bureau policy. This would entail minimal to no <br />inventory and afford protection to fossils of vertebrate species <br />only. Educational opportunities would not be developed <br />and, therefore, public awareness would be almost <br />nonexistent <br /> <br />Riparian Resources Management <br /> <br />Good to excellent riparian condition would be maintained <br />on approximately 1,400 inventoried acres, fair condition <br />on 74 acres, and poor condition on 274 acres. Changes <br />in livestock management would improve condition on 70 <br />acres. Land tenure adjustment would result in a significant <br />net increase in riparian vegetation and historical wetlands. <br />Development of historic wetlands for wildlife/fisheries <br />habitat would provide an additional 880 acres of riparian <br />vegetation, which excludes the open water portion of these <br />wetlands. <br /> <br />Inventory of an additional 1,413 acres would allow for <br />recognition and maintenance of riparian values in future <br />action plans. <br /> <br />Because of very limited BLM ownership and manageability <br />problems, IS acres on Kerber Creek would remain in poor <br />condition. <br /> <br />Standard stipulations would continue to be incorporated <br />into oil and gas and geotherma1leases to prevent long-term <br />degradation on 790 acres of riparian vegetation. Some losses <br />of vegetation would be expected due to surface occupancy, <br />but the extent and duration would be dependent on the <br />type of development NSO and seasonal limitations imposed <br />because of wildlife concerns would protect riparian <br />vegetation during the closure periods. <br /> <br />ENVIRONMENTAL CONSEQUENCES <br /> <br />Withdrawals would preclude any mining on 1,150 acres <br />(including Blanca Wildlife Habitat Area) and would protect <br />and maintain the riparian vegetation. Approximately 1,450 <br />acres with potential for mining activity would be protected <br />from undue and unnecessary damage by the 43 CFR 3809 <br />regulations. There would be short-term losses of vegetation <br />and a reduction in water quality, depending on the extent <br />of development. <br /> <br />Mitigating measures to maintain riparian condition would <br />be incorporated into any material sales within riparian zones. <br /> <br />Adherence to existing allotment management plans (AMPs) <br />would maintain good to excellent condition on 1,400 acres, <br />fair condition on 74 acres, and poor condition on 274 acres. <br />Implementation of the Poison Gulch AMP (Ford Creek <br />riparian demonstration area) would improve 70 acres from <br />poor or fair to good condition. Incorporation of riparian <br />objectives into some AMPs would benefit riparian vegetation <br />on the 1,413 acres not inventoried. Any newly developed <br />springs would be fenced, which would preserve small but <br />important communities of riparian vegetation. <br /> <br />Restoration of historic wetlands within the Blanca Wildlife <br />Habitat Area (WHA), the Emperius tract, and South Dry <br />Lakes would produce an additional 880 acres of riparian <br />vegetation. Maintenance of the Blanca WHA would ensure <br />protection of 1,025 acres of riparian vegetation. <br /> <br />Emphasis would be on acquisition of riparian areas. Disposal <br />of isolated tracts containing riparian vegetation would occur, <br />resulting in a loss of IS acres. <br /> <br />Surface-disturbing activities from vehicle use and earth- <br />moving activity on righ(s-{)f-way would cause short-term <br />damage to riparian vegetation. Mitigations would be required <br />to maintain current condition. <br /> <br />Increased recreation use along the Rio Grande River <br />Corridor would cause localized disturbance from trampling <br />and OHV use. Riparian vegetation would be protected by <br />OHV closures on 100 acres. OHV limitations that provide <br />seasonal closures and! or allow travel only on specified routes <br />would protect riparian vegetation on an additional 1,460 <br />acres, including the Blanca WHA. Seasonal closures are <br />often disregarded; therefore, new trails could occur in riparian <br />zones. The remainder of the planning area would remain <br />open to OHV use and this vehicle traffic would subject <br />riparian vegetation to degradation. <br /> <br />Protection of Cleome multicaulis, which is dependent on <br />saturated soils, would preserve small areas of riparian <br />vegetation. Any improvement or expansion of bald eagle <br />feeding habitat would improve or increase riparian <br />vegetation. <br /> <br />~ . <br /> <br />I <br />~ <br /> <br />I <br />Ii <br />I <br /> <br />4-9 <br />
