Editing Alcatraz (section)

==Natural features==

===Habitats===
A bluff that, because of its moist crevices, is believed to be an important site for California slender salamanders. 

Cliff tops at the island's north end. Containing a onetime manufacturing building and a plaza, the area is listed as important to nesting and roosting birds. 
The powerhouse area. A steep embankment where native grassland and creeping wild rye support a habitat for deer mice.
 
Tide pools. A series of them, created by long-ago quarrying activities, contains still-unidentified invertebrate species and marine algae. They form one of the few tide-pool complexes in the Bay, according to the report.
 
Western cliffs and cliff tops. Rising to heights of nearly 100 feet (30 m), they provide nesting and roosting sites for sea birds including pigeon guillemots, cormorants, Heermann's gulls and western gulls. Harbor seals can occasionally be seen on a small beach at the base. 

===Vegetation===
Historic gardens. Planted by prison guards' families, they are now overgrown and have also become a bird nesting habitat.
