After nearly 20 years of restoration, Mountain Lake is enjoying an exciting new chapter of life.

Take part in the fourth annual City Nature Challenge, an international community science competition to see which urban area can document the most nature.

​Join us for a Presidio bioblitz, where you'll help identify as many species as possible over a short period of time. We'l​l use iNaturalist, a community-powered website and app, to upload and share observations and to get help from other users. Bioblitzes are being held at 16 sites all around the Presidio!​​​​
