Natural Areas are areas of land which have scientific, educational and aesthetic value by reason of distinctive natural features. In Arizona, Natural Areas have as their primary purpose the protection and or preservation and study of the site’s natural resources.

Arizona State Parks and Trails has 3 Natural Areas and a conservation easement (San Rafael CE). The three natural areas are Sonoita Creek State Natural Area, the Verde River Greenway State Natural Area, and the San Rafael State Natural Area.

What Is The Natural Areas Program Advisory Committee?

The Natural Areas Program Advisory Committee (NAPAC) was created in 1999 by the Arizona State Parks Board. The group was to advise the Board on its Natural Areas acquisition program which was funded by the Heritage Fund monies generated by the Arizona Lottery. The Board charged NAPAC with advising it in areas requiring scientific expertise under the Arizona Heritage Fund statutes. Over the years, NAPAC’s role has evolved to include the development of recommendations and input on Natural Area land management planning, stewardship, and other natural resource conservation efforts within the State Parks system.

NAPAC is composed of seven voting members and one non-voting ex-officio member.  Voting members represent scientific expertise in the fields of botany, ecology, geology, hydrology, zoology, wildlife biology, preserve management or be actively involved in the conservation, scientific or preservation fields.

In achieving its Mission, NAPAC assists the State Parks by providing recommendations, review, and input on Natural Areas management plans, as well as natural resource assessment throughout the State Parks system. NAPAC facilitates opportunities to partner with local landowners, conservation organizations, and other state and federal agencies. NAPAC also evaluates suitability of properties for potential incorporation as a State Natural Area as part of the State Parks system.

NAPAC’s Mission and activities tier to the State Park Board’s Mission and Goals, through sustainable management, planning, research, and development of programs, partnerships, and conservation opportunities.
