Live Oak Associates, Inc. 2 <br /> <br /> <br />Methods <br /> <br />The June 2018 survey was timed to coincide with the blooming season for Congdon’s tarplant <br />and shining navarretia. <br />Ms. Peterson surveyed all areas of the project site occurring within the proposed limits of <br />grading and/or landslide repairs, and a minimum 75-foot buffer of these areas, in all areas that <br />provided suitable habitat for these species. The surveys were conducted on foot in such a way as <br />to achieve 100% visual coverage of the site and to conform to the California Department of Fish <br />and Wildlife’s (CDFW) 2009 Protocols for Surveying and Evaluating Impacts to Special Status <br />Native Plant Populations and Natural Communities. <br /> <br />All plant species encountered were identified to the taxonomic level necessary to determine <br />whether it was a special status plant species using The Jepson Manual Second Edition (Baldwin <br />et. al. 2012). <br /> <br />Findings/Conclusions <br /> <br />Appendix A provides a list of all vascular plant species that have thus far been encountered <br />during site surveys. <br /> <br />During the June 2018 survey, grasses on the site were extremely dense and dominated by wild <br />oats (Avena sp.). Grasses were mostly senescent, and plant diversity in all areas of the site <br />surveyed was extremely low, and made up almost exclusively of non-native species, including <br />wild oats (Avena barbata and A. fatua), wild-rye (Festuca perennis), field bindweed <br />(Convolvolus arvensis), black mustard (Brassica nigra) and curly dock (Rumex crispus). <br /> <br />Findings from the survey were negative for the occurrence of Congdon’s tarplant and shining <br />navarretia. Therefore, the project is expected to result in no impacts to these two species. A prior <br />survey in May 2018 ruled out the occurrence of all other special status plant species having <br />potential to occur on the site except for big tarplant. A third and final late summer or fall survey <br />will be required to ruleout the occurrence of this latter species on the site. <br /> <br />Please feel free to contact me at if you have any questions or concerns regarding our findings. <br /> <br />Sincerely, <br /> Pamela E.
