Between the Galiuros and Pinaleño mountains, the Sulphur Springs Valley is typical of the Basin and Range topography as the valley is an expansive grassland and desertscrub habitats that separates small mountain ranges of the sky islands. The area is home to a wintering population of sandhill cranes which relies on the surrounding agricultural lands for forage. The historic Sierra Bonita Ranch offers significant habitat for grassland birds as well as American pronghorn. Like other grasslands in southern Arizona, encroachment from woody plants like mesquite have potential to convert native grasslands. The Valley also acts as an important travel corridor for wildlife, linking areas south of I-10 with remote mountain ranges to the north such as the Galiuros and Winchesters.
Conservation Goals
- Remove invasive plant species in order to maintain the native grassland habitats for SGCN.
- Improve habitat connectivity in this vital north-south corridor.

Primary Threats
1. Agriculture
3. Climate Change and Severe Weather
4. Residential and Commercial Development
8. Invasive and Other Problematic Species
9. Natural System Modifications
Potential Conservation Actions
1. Land and Water Protection
- Develop conservation easements on private lands in order to maintain and protect wildlife habitat and connectivity areas.
2. Land and Water Management
- Remove non-native, undesirable, and/or invasive wildlife and plant species that may be encroaching on unique grassland habitats. Monitor the success of removal efforts.
- Remove barriers to improve landscape connectivity of this important north-south corridor.
- Develop alternatives that would improve connectivity across I-10, a major landscape barrier in the area.
- Improve water retention and reduce groundwater pumping to maintain quality grassland habitats.
3. Species Management
- Research potential of reintroducing black-tailed prairie dogs to the area.
5. Law and Policy
- Improve regulation of groundwater management.
6. Livelihood, Economic and Other Incentives
- Engage private landowners to partake in various conservation programs on agricultural lands to improve habitats for wildlife.
7. External Capacity Building
- Collaborate with partners to develop and implement management plans, conservation agreements, recovery actions, and research.
