Critical Habitat Maps
Keyhole Markup Language (KML/KMZ) Files
(KMZ files are zipped KML ones)
Use Google Earth, ArcGIS Explorer, or other programs to view critical habitat units superimposed on a map of California.
If you have one of the above programs set as your default KML/KMZ viewer, you will be asked whether you want to open or download the file.
NOTE: At the present time, we do not have KMZ files for any bird species. If you have a project in a coastal, forested or foothill area, it may be within critical habitat for the marbled murrelet, western snowy plover, northern spotted owl or California condor. See our main map page or use the Service's national Critical Habitat Mapper for these species.

For precise geospacial data about critical habitat, use the
Critical Habitat Mapper from our national website.
For anadromous fish (e.g. chinook salmon) and other ocean species, go to the NOAA Fisheries Service critical habitat GIS Data page.

Technical Notes
Transparency: In Google Earth, you can control the transparency of polygons (the geometric figures representing, in this case, critical habitat units.)
There is a slider at the bottom of the Places panel. Select one of the critical habitats and play with the slider. ArcExplorer has a similar feature.
Terrain: If you are having trouble seeing a critical habitat polygon, try clicking off Terrain in Layers.
