Critical Habitat Designation—2005

On August 11, 2005, the Service published a final critical habitat designation for 22 vernal pool ecosystem units in California and Oregon. However, we did not designate the critical habitat on a species by unit basis. The maps in this notice are for historic reference only, not for project development.

Designation of Species by Unit—2006

In a February 10, 2006, revision, we identified the designated critical habitat on a species by unit basis.

These are the maps to use if you want a general idea of which species are protected in a specific area. For more precise data, use the Service's national Critical Habitat Mapper.

The pdf version of the Federal Register notice (Federal Register 71:7117) is quite large (2 MB). For your convenience we have broken it down into parts that can be downloaded. See below.

The Plain text version of the Federal Register notice is much smaller (490 KB). It has unit descriptions but no maps.
