43 U.S.C. § 1901 : US Code - Section 1901: Congressional findings and declaration of policy

      (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,(!1) 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 December 15, 1971 (85 Stat. 649, 16 U.S.C. 1331
      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 section
      1711(a) of this title;
        (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 section 1712 of
      this title;
        (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.
