    APPENDIX D.2 Plant Survey Memorandum Athos Memo Report To: Aspen Environmental Group From: Lehong Chow, Ironwood Consulting, Inc. Date: April 3, 2019 Re: Athos Supplemental Spring 2019 Botanical Surveys This memo report presents the methods and results for supplemental botanical surveys conducted for the Athos Solar Energy Project in March 2019 and supplements the Biological Resources Technical Report (BRTR; Ironwood 2019) which reported on field surveys conducted in 2018. BACKGROUND Botanical surveys were previously conducted in the spring and fall of 2018 for the entirety of the project site for the Athos Solar Energy Project (Athos). However, due to insufficient rain, many plant species did not germinate for proper identification during 2018 spring surveys. Fall surveys in 2018 were conducted only on a reconnaissance-level due to low levels of rain. Regional winter rainfall from the two nearest weather stations showed rainfall averaging at 0.1 inches during botanical surveys conducted in 2018 (Ironwood, 2019). In addition, gen-tie alignments have changed slightly and alternatives, access roads and spur roads have been added. PURPOSE The purpose of this survey was to survey all new additions and re-survey areas of interest including public lands (limited to portions of the gen-tie segments), parcels supporting native vegetation and habitat, and windblown sandy areas where sensitive plant species may occur. The private land parcels in current or former agricultural use were not surveyed (parcel groups A, B, C, E, and part of G). METHODS Survey Areas: The area surveyed for biological resources included the entirety of gen-tie routes (including alternates), spur roads, access roads on public land, parcels supporting native vegetation (parcel groups D and F), and areas covered by windblown sand where sensitive species may occur (portion of parcel group G).

    Comparative Seed Manual: ASTERACEAE Christine Pang, Darla Chenin, and Amber M. VanDerwarker (Completed, April 17, 2019) This seed manual consists of photos and relevant information on plant species housed in the Integrative Subsistence Laboratory at the Anthropology Department, University of California, Santa Barbara. The impetus for the creation of this manual was to enable UCSB graduate students to have access to comparative materials when making in-field identifications. Most of the plant species included in the manual come from New World locales with an emphasis on Eastern North America, California, Mexico, Central America, and the South American Andes.
