APPENDIX 3.4-A - BIOLOGICAL RESOURCES DATA Attachments to Rincon del Rio Supplemental Biological Information CNDDB element list for nine quadrangles USFWS lists for nine quadrangles (some combined in one list; footnotes not included) CNPS on-line inventory query results for nine quadrangles (exported to Excel and superfluous columns of information deleted to make a page printable at an easily readable scale) CNPS online inventory results for 9-quadrangle area centered on Lake Combie (quadrangle containing the Rincon del Rio project site) Several of the species that appear in this list are not represented by occurrence records in the CNDDB. Absent other species-specific information, List 3 and 4 species cannot be shown to meet standard for significant impact under CEQA.
