Biodiversity in the Presidio in San Francisco

The Presidio Trust in San Francisco, California invites people of all ages to participate in the first Presidio Nature Challenge BioBlitz, on April 28, 2018. The event is part of the City Nature Challenge; a competition between cities around the globe measuring which one can observe and record the most species of plants and animals. The Presidio Nature Challenge inspires visitors to be stewards of San Francisco’s 1,491 acre urban National Park while helping the Presidio Trust in its commitment to increase the variety of living organisms within its boundaries.  More information is here.
