DOCKET 07-AFC-5 DATE SEP 24 2008 RECD. SEP 24 2008 Ivanpah Solar Electric Generating System (ISEGS) (07-AFC-5) Supplemental Data Response, Set 1D (Responses to: Biological Resources) Submitted to the California Energy Commission Submitted by Solar Partners I, LLC; Solar Partners II, LLC; Solar Partners IV, LLC; and Solar Partners VIII, LLC September 24, 2008 With Assistance from 2485 Natomas Park Drive Suite 600 Sacramento, CA 95833 Introduction Attached are supplemental responses (Set 1D) by Solar Partners I, LLC; Solar Partners II, LLC; Solar Partners IV, LLC; and Solar Partners VIII, LLC (Applicant) to the California Energy Commission (CEC) Staff’s data requests for the Ivanpah Solar Electric Generating System (Ivanpah SEGS) Project (07-AFC-5). These data requests are the result of the workshop discussion held at Primm, Nevada on June 23, 2008.Within each discipline area, the responses are presented in alphabetical order and are numbered for tracking and reference convenience. New graphics or tables are numbered in reference to the Supplemental Data Request number. For example, if a table were used in response to Data Request AQ-1, it would be numbered Table AQ1-1. The first figure used in response to Data Request AQ-1 would be Figure AQ1-1, and so on. AFC figures or tables that have been revised have “R1” following the original number, indicating revision 1. Additional tables, figures, or documents submitted in response to a supplemental data request (supporting data, stand-alone documents such as plans, folding graphics, etc.) are found at the end of a discipline-specific section and may not be sequentially page-numbered consistently with the remainder of the document, though they may have their own internal page numbering system. The Applicant looks forward to working cooperatively with the CEC and Bureau of Land Management (BLM) staff as the Ivanpah SEGS Project proceeds through the siting process. We trust that these responses address the Staff’s questions and remain available to have any additional dialogue the Staff may require.

The proposed Ivanpah SEGS site is located in eastern San Bernardino County, in the Ivanpah Valley, 4.5 miles southwest of the town of Primm, Nevada. Protocol-level surveys for special-status plants were conducted throughout the project area in 2008 and 2007. The location of the site elements is shown on figures provided in Appendix A. Small adjustments to the project boundary were made in 2008; therefore, the 2008 survey boundary differs slightly from the boundaries shown on the 2007 maps. An area designated as the one-mile buffer surrounds the Property Boundary and extends out in all directions from it to a distance of one mile. Reconnaissance-level

    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).

    March 21, 2014

    Welcome to the 32nd Annual Wild Flower Hotline, brought to you by the Theodore Payne Foundation, a non-profit plant nursery, seed source, book store, and education center dedicated to the preservation of wild flowers and California native plants. This a report for March 21, 2014. New reports will be posted each Friday through the end of May. The Mojave Desert is still the place to be this week, although I will include a few more good sights as many of you are starting Spring Break and may want to explore other areas as well. Let’s start with our first report from the Southern Sierra near Sequoia & Kings Canyon National Parks. The park region has had a dry season. Blooming appears to be early and short, but along Hwy 198 near Sequoia National Park look for Western redbud (Cercis occidentalis) in full bloom now. There have been spotty sightings of silver bush lupine (Lupinus albifrons) as well. There are bright orange patches of fiddleneck (Amsinckia menziesii) and the California poppies (Eschscholzia californica) are just starting to appear. Further north at Yosemite/Hetch Hetchy, flowers are starting to bloom, but it is still early in the season. Because of the Rim Fire last year, the only trail available is the one from the dam to Wapama and Rancheria Falls. (The trail to Poopenaut Valley is closed.) In the moist areas look for red maids (Calandrinia ciliata), and a few harlequin lupines (Lupinus stiversii), which are just getting started. Some of the larger pools of flowing water still contain Sierra newts (Taricha sierrae).

LaRue, Jr., the Principal Investigator under a Memorandum of Understanding (MOU) with the California Department of Fish and Wildlife (CDFW) (expires 4/30/2016), Scientific Collecting Permit Number SC-001544, reports results of trapping surveys to assess the presence of the state-listed, Threatened Mohave ground squirrel (MGS) (Xerospermophilus mohavensis) on the subject property. This study, which was completed on the Butte Valley Wildflower Sanctuary (herein “Butte Valley” or “Sanctuary”) in northeastern Los Angeles County (Figures 1 through 3), California is authorized under Permit Number 000972. In recent decades, there have been very few MGS records in the desert region of northeastern Los Angeles County. In spite of protocol trapping efforts since 1998, the only confirmed MGS captures in Los Angeles County have been at several locations in a small area on Edwards Air Force Base (Leitner 2008).

    Vascular Flora of West Clear Creek Wilderness, Coconino and Yavapai

    VASCULAR FLORA OF WEST CLEAR CREEK WILDERNESS, COCONINO AND YAVAPAI COUNTIES, ARIZONA By Wendy C. McBride A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Biology Northern Arizona University May 2016 Approved: Tina J. Ayers, Ph.D., Chair Randall W. Scott, Ph.D. Liza M. Holeski, Ph.D. ABSTRACT VASCULAR FLORA OF WEST CLEAR CREEK WILDERNESS, COCONINO AND YAVAPAI COUNTIES, ARIZONA WENDY C. MCBRIDE West Clear Creek Wilderness bisects the Mogollon Rim in Arizona, and is nested between the Colorado Plateau and Basin and Range physiographic provinces. Between 2013 and 2016, a floristic inventory vouchered 542 taxa and reviewed 428 previous collections to produce a total plant inventory of 594 taxa from 93 families and 332 genera. The most species rich families Were Asteraceae, Poaceae, Fabaceae, Brassicaceae, Rosaceae, Plantaginaceae, Cyperaceae, and Polygonaceae. Carex, Erigeron, Bromus, Muhlenbergia, and Oenothera Were the most represented genera. Nonnative taxa accounted for seven percent of the total flora. Stachys albens was vouchered as a new state record for Arizona. New county records include Graptopetalum rusbyi (Coconino), Pseudognaphalium pringlei (Coconino), Phaseolus pedicellatus var. grayanus (Coconino), and Quercus rugosa (Coconino and Yavapai). This study quantified and contrasted native species diversity in canyon versus non- canyon floras across the Southwest. Analyses based on eighteen floras indicate that those centered about a major canyon feature shoW greater diversity than non-canyon floras. Regression models revealed that presence of a canyon Was a better predictor of similarity between floras than was the distance betWeen them. This study documents the remarkable diversity found Within canyon systems and the critical, yet varied, habitat they provide in the southwestern U.S.
