<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>TIME PERIOD COVERED These data were collected between May-July 2004 by field crews working for California Department of Fish and Game. </SPAN></P><P><SPAN>GEOGRAPHIC EXTENT OF THE RECORDS Vegetation plots occur in two study areas on public lands in Yuba and Tehama Counties in the Sierra Nevada foothills. </SPAN></P><P><SPAN>NUMBER OF RECORDS There are 183 records with habitat attributes measured from 0.05 - 0.10 hectare sampling plots. </SPAN></P><P><SPAN>BASE DATA STRUCTURE The file is a flat Excel table which gives vegetation attributes for each habitat plot. Each habitat plot is represented by two key fields called "SAMPLE_ID" and "PLOT_NUM" which relate these habitat records to bird and herpetile survey data collected in the same year from the same sample points. </SPAN></P><P><SPAN>WHAT EACH RECORD REPRESENTS Each record in the table represents the average values for habitat attributes from plots that can be linked with bird count data from the same points. Average values for each sample represent the mean of average values from 3 habitat plots measured at each point.</SPAN></P></DIV></DIV></DIV>
