Our mission:


Founded February 1, 2018, the Association for Native American Sacred Trees and Places  (NASTaP) inspires discovery, appreciation, and conservation of culturally modified trees and places held sacred to Native Americans. 

Our purpose is inclusive of:

  • Culturally Modified Trees (CMTs)

  • Modified stones, stacked rocks, and rock art

  • Ceremonial landmarks and landscapes

  • Native American natural science

  • Stewardship of the earth, land, water, and sky

Guiding Principles:

· No one person, tribe, or group has all the answers or is the single authority on Native American sacred trees and places.

· Together, we can conduct better research, identification, interpretation, documentation, education, and conservation.

· We strive for cultural appreciation, not appropriation.

· Our activities are inclusive of all tribes and non-native people who wish to research, discover, understand, share, appreciate, and conserve Native American sacred trees and places.
