((a)) The Congress finds and declares that—
((1)) vast segments of the public rangelands are producing less than their potential for livestock, wildlife habitat, recreation, forage, and water and soil conservation benefits, and for that reason are in an unsatisfactory condition;
((2)) such rangelands will remain in an unsatisfactory condition and some areas may decline further under present levels of, and funding for, management;
((3)) unsatisfactory conditions on public rangelands present a high risk of soil loss, desertification, and a resultant underproductivity for large acreages of the public lands; contribute significantly to unacceptable levels of siltation and salinity in major western watersheds including the Colorado River; negatively impact the quality and availability of scarce western water supplies; threaten important and frequently critical fish and wildlife habitat; prevent expansion of the forage resource and resulting benefits to livestock and wildlife production; increase surface runoff and flood danger; reduce the value of such lands for recreational and esthetic purposes; and may ultimately lead to unpredictable and undesirable long-term local and regional climatic and economic changes;
((4)) the above-mentioned conditions can be addressed and corrected by an intensive public rangelands maintenance, management, and improvement program involving significant increases in levels of rangeland management and improvement funding for multiple-use values;
((5)) to prevent economic disruption and harm to the western livestock industry, it is in the public interest to charge a fee for livestock grazing permits and leases on the public lands which is based on a formula reflecting annual changes in the costs of production;
((6)) the Act of (, et seq.), continues to be successful in its goal of protecting wild free-roaming horses and burros from capture, branding, harassment, and death, but that certain amendments are necessary thereto to avoid excessive costs in the administration of the Act, and to facilitate the humane adoption or disposal of excess wild free-roaming horses and burros which because they exceed the carrying capacity of the range, pose a threat to their own habitat, fish, wildlife, recreation, water and soil conservation, domestic livestock grazing, and other rangeland values;
((b)) The Congress therefore hereby establishes and reaffirms a national policy and commitment to:
((1)) inventory and identify current public rangelands conditions and trends as a part of the inventory process required by ;
((2)) manage, maintain and improve the condition of the public rangelands so that they become as productive as feasible for all rangeland values in accordance with management objectives and the land use planning process established pursuant to ;
((3)) charge a fee for public grazing use which is equitable and reflects the concerns addressed in paragraph (a)(5) above;
((4)) continue the policy of protecting wild free-roaming horses and burros from capture, branding, harassment, or death, while at the same time facilitating the removal and disposal of excess wild free-roaming horses and burros which pose a threat to themselves and their habitat and to other rangeland values;
((c)) The policies of this chapter shall become effective only as specific statutory authority for their implementation is enacted by this chapter or by subsequent legislation, and shall be construed as supplemental to and not in derogation of the purposes for which public rangelands are administered under other provisions of law.
