Mission & Focus Areas
The Foundation’s stated mission is to protect biodiversity. Its website describes place-based programs in Alaska, the California Floristic Province, Montana, and Chilean Patagonia, alongside broader work in bird conservation, systemic support for wildlife corridors and other protections, global biodiversity, and environmental education. Its website also identifies education topics including sustainable consumption, international issues, and environmental education.
The Foundation says its Global Biodiversity work is mainly located in Africa and Latin America. Its objectives include protecting biodiversity hotspots and endangered species, involving local or Indigenous communities in stewardship, supporting conservation-related sustainable livelihoods, and developing wildlife corridors. Its Conservation Infrastructure program prioritizes legal, policy, institutional, civic, and scientific frameworks that support durable conservation.
The 2024 grantees illustrate the range of organizations supported. The Center for Biological Diversity describes its work as using science, law, and creative media to protect species and the lands, waters, and climate they need. The Vital Ground Foundation says it works to protect and restore wildlife habitat and landscape linkages and to prevent conflicts between people and wildlife. American Bird Conservancy describes its mission as conserving wild birds and their habitats throughout the Americas. Population Media Center says it uses entertainment media to promote smaller families, family planning, women’s status, gender equity, and global sustainability. These are the grantees’ descriptions of their own work.
