These data are habitat polygons within a 200-m radius around point locations where wildlife surveys were conducted along 19 randomly selected watercourses in the foothills of the Sierra Nevada Mountain Range from Butte to Calaveras counties. These wildlife surveys included point counts of birds (from 10-minute counts) within 100-m radius circles, and playback surveys of hawks and owls. Bird point count surveys were conducted between 25 March 2005 and 30 June 2005, while the hawk and owl surveys were conducted between 28 March 2005 and 19 July 2005. These data are from 74 sample points along the 19 watercourses. Habitat polygons were delineated from DOQQs and then field verified in July-August 2005.
The data were part of a larger study of wildlife use of riparian habitat along Sierra Nevada foothill watercourses.

It is assumed that the locations of the points and the delineated polygons are accurate with regard to the actual locations on the ground where the surveys were done and the habitat polygons were delineated.
These 74 points are consistent. There are 3-5 points for each watercourse segment which are indicated as such in the data table, and the watercourses and sample points in this data set had at least 3 point counts and 3 playback surveys conducted at each point.
Most of the habitat polygons were field verified, and most of the habitat polygons were completely typed. A small proportion, however, were not field verified or lack habitat stages. Otherwise, all data are complete.
The location accuracy of the delineated polygon boundaries is + or - 10 m.
Habitat polygons were delineated between May-June 2005 with ArcGIS and recent black and white DOQQs. Polygons within 200 m radius of the sample point were delineated. Habitat polygons were field verified between July-August 2005, and corrections were made with ArcGIS.
