*Every effort was made to ensure accuracy of all GIS themes used. All known errors were corrected. Some themes were created lat in the science process using aerial photo interpretation only. These themes, including foothill riparian woodlands and fresh emerg wetlands, were not subject to field validation. 100% accuracy of all themes is not implied or guaranteed. None of these themes sho be used in lieu of project level biological inventories.
