Mount Sutro Open Space hosts a variety of native plant communities including some locally rare plants amidst the remnants of Adolph Sutro's eucalyptus plantation. Once common, under pressure from an increasingly urban environment, plants such as California pipevine, fairy bells, hawkweed, and slim Solomon persist on Mount Sutro, preserved as a permanent Open Space. Mount Sutro offers habitat to the city's wildlife residents including skunks, raccoons, occasional coyotes, numerous species of birds, salamanders, butterflies, bees, spiders, and many insects.
