The 53,750-acre Santa Rita Wildlife Area (SRWA) is located south of Tucson in the grasslands on the north side of the Santa Rita Mountains in Pima County. The boundary for the COA is concurrent with the boundary for the Santa Rita Experimental Range, owned by the Arizona State Land Department (ASLD) with shared management by the University of Arizona (UA). The experimental range acts as an outdoor laboratory for UA’s College of Agriculture and Life Sciences.
The COA is semi-desert grassland recently invaded by mesquite, cholla, catclaw acacia, and Lehmann lovegrass. As a result, the semidesert grassland habitat is converting into shrubland. Common wildlife species of the COA include cottontails, jackrabbits, coyotes, javelina, deer, quail, dove, and numerous lizards, snakes, rodents, and songbirds, many of which are SGCN.
Conservation Goals
- Maintain and improve grassland habitats and reduce encroachment from woody plants.

Primary Threats
1. Agriculture
4. Residential and Commercial Development
7. Human Intrusions and Disturbance
8. Invasive and Other Problematic Species
Potential Conservation Actions
1. Land and Water Protection
- Develop conservation easements on public or private lands in order to maintain and protect wildlife corridors.
2. Land and Water Management
- Improve management of cattle and other trespass livestock that may adversely-impact habitats.
- Maintain and protect wildlife corridors from encroaching residential development around the COA.
- Implement the AZGFD-UA MOU Wildlife Area plan to reduce adverse effects of OHV use and other irresponsible recreational activities.
- Monitor and manage woody and invasive plant species that are encroaching on native grassland habitats, including Lehmann's lovegrass and mesquite.
- Reintroduce prescribed burns to increase habitat resiliency and improve quality of native grassland habitats.
7. External Capacity Building
- Continue building partnerships to develop actionable and innovative grassland and range management strategies.
