Federal Laws Significant to the Natural Resource Career Field

Below is a list of federal laws related to natural resource management. These laws are covered in many introductory natural resource classes because they provide a glimpse into the foundation of the National Park Service's (NPS) constitutional authority, as well as the laws that created and strengthened it. These laws also represent highlights from key environmental legislation that contributes to the preservationist nature of the NPS. This list is not meant to be all inclusive; numerous laws can be found outside this list. To learn more about federal laws that affect the NPS visit the Natural Resource Catalog page to find a law and policy course that meets your needs.

Service-wide laws, such as the National Park Service Organic Act and the National Park System General Authorities Act, used to reside in Title 16 of the U.S. Code. However, Title 16 was becoming large and disorganized, as it included laws from multiple land management and other federal agencies. To address this, in December 2014, Congress created a new Title 54 of the U.S. Code, that includes only laws applicable to the National Park Service. Read the full memo about the move here.

With the Wilderness Act Congress established the National Wilderness Preservation System by setting aside certain federal lands as wilderness areas.

National Environmental Policy Act

42 U.S.C. 4321-4347


This landmark environmental protection legislation's basic policy is to assure that all branches of government give proper consideration to the environment prior to undertaking any major federal action that significantly affects the environment.. NEPA requires all federal agencies including the NPS to:

  • Prepare in-depth studies detailing the impacts of and alternatives to proposed "major federal actions";
  • Use the information contained in such studies when deciding whether to proceed with the actions; and
  • Diligently attempt to involve the interested and affected public before any decision affecting the environment is made


General Authorities Act

54 U.S.C. 100101(b) et seq.


Congress redefined the National Park System to be "...any area of land and water... administered by the Secretary... through the National Park Service for park, monument, historic, parkway, recreational, or other purposes."

Congress stated that all units of the system are united in one system and that the system is to be preserved and managed for the benefit and inspiration of all the people of the Untied States. This act makes clear that, in addition to the unit-enabling act, the Organic Act governs all units.

States take the lead but must not fall below the federal standard.


Clean Air Act

42 U.S.C. 7401-7671q


The Clean Air Act (CAA) is the comprehensive federal law that regulates air emissions from stationary and mobile sources.
