This Important Bird Area (IBA) lies in the floodplain valley between the Patagonia and Santa Rita Mountains of southeastern Arizona and contains some of the richest remaining riparian habitat in the region. The Fremont cottonwood-Goodding’s willow forest within the preserve is a rare example of what once dominated Arizona’s river and stream corridors. Sonoita Creek provides for a wide array of diverse species from endangered fishes to butterflies and birds. An exceptionally diverse assemblage of riparian associated bird species have been documented, including nesting gray hawks, yellow warblers, Lucy’s warblers, Abert’s towhees, and Bell’s vireos. The Preserve is visited by thousands of people every year seeking to see and experience its rich natural diversity. Also within this IBA is the Tucson Audubon Society’s Paton Center for Hummingbirds, a premier birding destination. The Nature Conservancy actively manages the Preserve for its wildlife and habitat values, and the site serves as an outdoor classroom for several innovative environmental education activities.
Conservation Goals
- Maintain and enhance habitat integrity and diversity, and unfragmented habitat that provides adequate forage or prey, cover, and water for healthy wildlife populations.
- Conduct monitoring and targeted removal efforts to limit establishment and spread of invasive species.
- Maintain and increase surface water quality and quantity to improve rare riparian habitats for wildlife, both common and SGCN.
- Maintain hydrologic research and monitoring and ensure groundwater pumping does not adversely affect the subflow zone.

Primary Threats
3. Climate Change and Severe Weather
4. Residential and Commercial Development
6. Energy Production and Mining
9. Natural System Modifications
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).
- Work with public partners and private landowners to maintain/improve surface water for wildlife.
- Conduct monitoring and targeted removal efforts to limit establishment and spread of invasive species.
3. Species Management
- Maintain riparian habitats to support populations of western yellow-billed cuckoos and other SGCN.
7. External Capacity Building
- Facilitate and fund collaborative organizations to support coordinated management of the watershed.
- Partner with the mining industry to ensure environmental responsibility with any potential projects and minimize impacts to surface and subsurface water regimes.
