Preservation Guidance

Preservation is the practice of sustaining something by keeping it intact, free from harm, and safe from deterioration. For the National Park Service, historic preservation is the act of protecting and sustaining cultural and natural resources in perpetuity.

The identification and preservation of cultural resources is critical to protecting the nation's richly textured history. Cultural resources include tangible items of historic or cultural significance, such as cultural landscapes, buildings, structures, and objects; as well as the intangible items, like traditional knowledge, practices, and life-ways.

Cultural landscapes have been recognized by the NPS as cultural resources since 1983. Our responsibility for their preservation is equal to other resources, regardless of the landscape type or level of significance.
