Federal Historic Preservation LawsBeginning with the Organic Act (1916), the NPS has understood its mission: “To conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and such means as will leave them unimpaired for the enjoyment of future generations.” The Cultural Resource laws, policies, and guidelines that preceded and followed this establishing legislation have been Congress’s and the NPS’s attempts to expand our understanding of cultural resources and Cultural Resources Management.  Cultural Resource policies and guidelines strive to integrate cultural resource concerns into broader NPS Mission.  They seek to avoid or minimize harm to cultural resources, to identify the most appropriate uses for cultural resources, and to determine the ultimate treatment for cultural resources.
