POST protects open space on the Peninsula and in the South Bay for the benefit of all.
POST is creating a network of protected lands where people and nature connect and thrive. These lands are preserved forever so present and future generations benefit from the careful balance of rural and urban landscapes that makes our region extraordinary.
Since our founding in 1977, POST has protected more than 83,000 acres of permanent open space, farms and parkland in San Mateo, Santa Clara and Santa Cruz counties. Discover more about our process and the areas POST has worked to preserve.

In 2022, POST finalized a new strategic plan to help shape our path forward. After input from our staff, board and partners, as well as a close look at the state of conservation in our region, we landed on three priorities that will shape our work: building climate resilience, preserving biodiversity and creating equitable access.
POST will implement land protection and management strategies that build adaptive capacity and resilience to climate change impacts — including drought, fire and increased temperatures.
POST will protect, restore, steward and functionally connect a mosaic of habitats and land uses across our region that preserve our unique biodiversity.
POST will create and nurture sustainable long-term connections between people and nature, addressing current inequities by centering underserved and historically excluded communities in our work.
