This COA contains the majority of the Tucson-area sky islands as well as many Important Bird Areas (IBAs) found in upland Sonoran desertscrub. This COA also covers portions of the Santa Catalina and Rincon mountains, and the Rincon Mountain District of Saguaro National Park. Owing in part to the extensive elevational range, this COA contains a variety of habitat types, ranging from semidesert grassland and Sonoran desertscrub to Madrean woodland and Petran montane conifer forest. In addition to its vertebrate diversity, this area contains native land snails of the genus Sonorella and Naesiotus, and possibly undiscovered Pyrgulopsis springsnail populations. Nearly all of the land within this COA is public, which, coupled with its proximity to Tucson, makes it important for ecotourism and outdoor recreation, especially hiking, birding, climbing, and mountain biking.
- Reintroduce fire regimes, where possible, to increase landscape resiliency.
- Control invasive plant species at manageable levels that promote healthy, intact desertscrub, grasslands, woodlands, and forest habitats.
- Maintain and improve status and distribution of endemic SGCN snails and reduce threats to their populations and habitat.
- Conserve and protect a unique example of a sky island ecosystem and the populations of SGCN avian species that depend on them.
- Increase connectivity to other mountain ranges and significant wildland blocks.

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
- Conserve or improve areas for migratory birds identified as important habitats during any part of their annual life cycle (breeding, stopover, or wintering).
- Conduct monitoring and targeted removal efforts to limit establishment and spread of invasive species (e.g. buffelgrass, fountain grass).
- Manage for forest thinning and prescribed burns to create healthy habitats less prone to catastrophic wildfires and resilient to drought and insect infestations.
3. Species Management
- Implement conservation actions to promote populations of SGCN species, including translocations and insurance populations when necessary.
- Conduct surveys and monitor populations of SGCN as specified in work plans and job statements
- Manage habitats for desert bighorn sheep populations, including removing invasive plant species and restoring natural fire regimes.
- Improve management and restoration of agave species to provide resources and migration corridors for lesser long-nosed bat and other pollinator species.
- Rescue (salvage) native aquatic wildlife at risk from imminent threats, and return salvaged wildlife when conditions are appropriate.
4. Education and Awareness
- Develop outreach programs for the public on impacts to wildlife, agriculture, and recreation from introduced species.
- Incorporate citizen science programs to identify distribution of invasives ( SEEDN, iMapInvasives, etc.).
5. Law and Policy
- Work with local governments to incorporate wildlife protections and habitat connectivity into general plans.
- Improve OHV management and enforcement to reduce adverse impacts to habitats.
7. External Capacity Building
- Support partnerships and alliances to promote information sharing, learning, and collaboration.
