The Arizona Site Steward Program is an organization of volunteers, in partnership with public land managers of Arizona (US Forest Service, AZ State Lands, BLM, and other jurisdictions), whose members are selected, trained and certified by Arizona State Parks & Trails (ASPT). The chief objective of the Stewards Program is to deter the theft of antiquities and report to the land managers any destruction or vandalism of prehistoric and historic archaeological and paleontological sites in Arizona through site monitoring.
