Pima County Zoning Code Chapter 18.72 (Native Plant Preservation) requires protection and salvage of certain native plants during development. Saguaro cacti, ironwood, palo verde, and mesquite are specifically protected. Arizona Native Plant Law (ARS 3-901 et seq.) requires permits to destroy or relocate protected plants.

City-specific rules exist: Marana, Oro Valley, and Tucson have their own native plants rules that differ from Pima County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Full Breakdown

72 addresses native plant preservation during land development in unincorporated areas. The ordinance requires developers to survey, tag, and either preserve in place or salvage and transplant protected native plants including saguaro (Carnegiea gigantea), barrel cactus, ironwood (Olneya tesota), palo verde, and mesquite. Arizona Native Plant Law (ARS 3-901 through 3-934) makes it illegal to destroy, mutilate, or remove protected native plants from any land without the landowner's permission and, on state trust land, without an Arizona Department of Agriculture permit. Saguaro cacti are the most iconic protected species; removing or destroying a saguaro on your own property is legal with proper notification to the Arizona Department of Agriculture (notification required 20-60 days before removal, per ARS 3-906).

Pima County sits in the Sonoran Desert Upland subdivision, home to the densest saguaro forests in the world near Saguaro National Park East and West units. Buffer-zone properties near the park face additional scrutiny during development review. Xeriscape (low-water, native-plant landscaping) is the standard for new development.

Frequently Asked Questions

Can I remove a saguaro from my property?
Yes, but you must notify the Arizona Department of Agriculture 20-60 days before removal (ARS 3-906). Destroying a saguaro on someone else's land without permission is a Class 4 felony.
What does Pima County require for native plants during development?
Chapter 18.72 requires developers to survey, tag, and either preserve or transplant protected native plants. This applies to all new development in unincorporated areas.
