The Presidio Trust has prepared a series of short films highlighting ecology in the Presidio and efforts to identify, monitor, and conserve flora, fauna, and natural systems. The Presidio’s diverse landscape protects the most complete remaining mosaic of natural systems in San Francisco, with a high density of rare and endangered plants, and an unusually high diversity of invertebrate and wildlife species for a park in an urban location. The Presidio is also a very human place where people and nature thrive in harmony. This film is by Melissa Peabody. Copyright 2010, Presidio Trust.
