Presidio Environmental Health Report 2020-2022

The Presidio Environmental Health Report 2020-2022 is a self-assessment of the Presidio Trust’s progress in increasing biodiversity in the Presidio national park site. It tracks five key metrics including native plant cover, threatened and endangered species population estimates, invasive species, biodiversity, and water quality.

Mountain Lake Restoration

The Presidio Trust successfully revitalized the once-polluted Mountain Lake through a comprehensive ecological restoration project, bringing back the lake’s native wildlife and plant species, and creating a thriving ecosystem for visitors to enjoy. See how we’re doing in the Presidio Trust Mountain Lake Update 2021.
