Sky Island Alliance is a nonprofit conservation organization dedicated to protecting and restoring the Madrean Sky Islands region that spans southeastern Arizona, southwestern New Mexico, and northern Sonora and Chihuahua. The organization works on habitat connectivity, species protection, and community-based stewardship across landscapes that include mountain ranges, grasslands, and desert biomes. It partners with federal agencies, state agencies, Indigenous nations, universities, and local conservation groups to implement science-based projects and outreach.

History

Founded in 1999, the organization emerged amid rising concern about habitat fragmentation in the Madrean Sky Islands bioregion, a transboundary area that links the Rocky Mountains and the Sierra Madre Occidental. Early collaborations involved researchers from the University of Arizona, conservationists from the The Nature Conservancy, and land managers from the U.S. Forest Service and the U.S. Fish and Wildlife Service. Over the 2000s the group expanded its footprint through partnerships with tribal governments such as the Tohono O'odham Nation and the Akimel O'odham, municipal agencies in Tucson, Arizona and Nogales, Arizona, and Mexican organizations including staff linked to the Sonoran Institute. In the 2010s the organization increased monitoring programs alongside academic partners including Arizona State University and the University of New Mexico, while engaging with international initiatives tied to the North American Bird Conservation Initiative and the Convention on Biological Diversity agendas.

Mission and Programs

The organization’s stated mission centers on conserving biodiversity and restoring connectivity in the Madrean Sky Islands through habitat restoration, species protection, and community science. Primary programs include landscape-scale connectivity planning that informs management on Coronado National Forest, invasive species control projects conducted in coordination with National Park Service staff at sites like Chiricahua National Monument, and restoration initiatives on private lands working with the Natural Resources Conservation Service. Other program areas prioritize pollinator habitat, riparian restoration along tributaries feeding the Santa Cruz River, and fire-adapted ecosystem resilience in collaboration with the Bureau of Land Management.

Conservation Initiatives

Conservation initiatives emphasize protecting focal species and ecological processes across international boundaries. Projects target species such as the jaguar-linked connectivity efforts that intersect with cross-border work involving CONANP reserves in Sonora, and bird-focused initiatives aligned with the Partners in Flight strategy. Habitat corridors are identified through partnerships with landscape planners from World Wildlife Fund offices and the Wildlife Conservation Society. Restoration work includes eradication efforts for invasive plants coordinated with the Arizona Game and Fish Department and re-establishment of native grasses with support from the Natural Resources Defense Council and regional land trusts like the Sky Island Alliance Land Trust-related partners.

Research and Monitoring

Research and monitoring combine field surveys, remote sensing, and community science platforms. Studies on species distributions have been conducted with researchers from the Museum of Southwestern Biology and the Desert Laboratory on Tumamoc Hill, while climate-change modeling has been pursued with teams at the Institute of the Environment (University of Arizona) and climate researchers linked to the Intergovernmental Panel on Climate Change frameworks. Monitoring of pollinators and avifauna uses protocols aligned with the Audubon Society and Breeding Bird Survey collaborators from the Cornell Lab of Ornithology. Camera-trap and telemetry projects for carnivores have been run jointly with biologists affiliated with the University of California, Santa Cruz and international partners in Mexico.

Community Engagement and Education

Local engagement integrates volunteer stewardship, youth education, and cross-border dialogue. Programs include volunteer restoration days partnered with municipal agencies in Green Valley, Arizona and community workshops co-hosted with the Tucson Audubon Society and Indigenous educators from the Tohono O'odham Community College area. Educational curricula have been developed in collaboration with K–12 outreach teams from the Arizona-Sonora Desert Museum and citizen-science initiatives linked to platforms used by the National Phenology Network. Public events and speaker series bring together staff from the U.S. Forest Service, academic scholars, and conservation practitioners from regional NGOs.

Organizational Structure and Funding

Governance is provided by a volunteer board of directors composed of conservation professionals, academics, and community leaders, while day-to-day operations are managed by an executive director and program staff. Funding sources include private foundations such as the MacArthur Foundation-style philanthropy, project grants from federal agencies like the U.S. Fish and Wildlife Service and the National Fish and Wildlife Foundation, corporate sponsorships, and individual donors. The organization leverages partnerships with universities including the University of Arizona and with international conservation programs administered by entities such as the Inter-American Development Bank for transboundary project support.
