1.0 INTRODUCTION This report documents the results of HELIX Environmental Planning, Inc. s (HELIX s) 2015 Quino checkerspot butterfly (Euphydryas editha quino; QCB) survey of the Palo Verde Ranch Project site (project). HELIX biologists performed the protocol survey (comprised of 7 site visits) under HELIX s Threatened/Endangered Species Permit No. TE778195. The approximately 540-acre study area for the project is located within the east-central portion of unincorporated San Diego County, California (Figure 1). It is further located within Sections 1 and 2 of Township 16 South, Range 2 East of the U.S. Geological Survey (USGS) 7.5-minute Viejas Mountain quadrangle maps (Figure 2). Elevations within the study area range between approximately 1,480 feet to 2,250 feet above mean sea level. An aerial photograph of the parcel in included as Figure 3. 2.1 HABITAT ASSESSMENT 2.0 METHODS A habitat assessment was conducted on February 11, 2015 by HELIX biologist Jasmine Bakker The majority of the project site and surrounding habitat is characterized by dense southern mixed chaparral which forms a closed canopy and is inaccessible to pedestrian access. This habitat is unsuitable for QCB and is excluded from the survey area based on the current USFWS Survey Guidelines (USFWS 2014). Approximately 12.9 acres of the 540-acre study area, roughly 2 percent, were mapped as potentially suitable habitat during Ms. Bakker s assessment. The current survey area for the 2015 QCB survey is depicted in Figure 4. The mapped survey area consists of small pockets of bare ground surrounded by dense shrubs. However, large portions of the mapped survey area still consist of fairly dense shrubs which required surveyors to physically move branches in order to navigate the area; areas too dense to navigate were not surveyed during the site visits. 2.2 FOCUSED QCB SURVEYS Seven protocol site visits were conducted by Ms. Bakker and HELIX biologists Erica Harris and Rob Hogenauer (Table 1). HELIX biologists Tara Baxter, Laura Moreton, Benjamin Rosenbaum, and George Aldridge participated as supervised individuals. Pedestrian surveys consisted of walking roughly parallel transects through appropriate habitat and identifying butterflies by sight and with the aid of binoculars. Larval host plants were mapped with the aid of hand-held Global Positioning System (GPS) units, and potential nectar plant species were also documented (Figure 4). Surveyors covered between 1 and 5 acres per hour. In accordance with the current QCB guidelines, the surveys began the third week of February and were anticipated to continue to the second Saturday in May. Specifically, surveys were conducted between February 17 and March 31, 2015. The first QCB in Riverside County was reported at Oak Mountain by Adam Malisch on February 26, 2015 (Quino Biologists United 2015). The first QCB in San Diego County was reported at Marron Valley by Alison Anderson Quino Checkerspot Butterfly Survey Report for the Palo Verde Ranch Project / CAA-01 / May13, 2015 1
on March 12, 2015; however, additional sightings of QCB within San Diego County were limited. Protocol surveys were terminated prior to the end of the survey period due to the on-site condition of host plants and nectaring resources in addition to the lack of regional QCB sightings. Few nectaring resources were observed on the March 31 survey and the number of host plants present was significantly lower than during previous surveys. Host plants and the majority of nectaring plants had already set seed and had begun to senescence. 2.3 NOMENCLATURE Identification of butterflies was based on personal knowledge, museum specimens, the San Diego Natural History Museum website, and field guides by Shiraiwa (2009) and Glassberg (2001). Other nomenclature for this report is taken from Holland (1986) and Oberbauer (2008) for vegetation communities and Baldwin et al. (2012) for plants. 3.0 RESULTS Dates, times, and weather conditions at the start and finish of each site visit are presented in Appendix A. Copies of field notes taken are provided as Appendix B. A list of total butterflies observed during the 2015 protocol QCB surveys is included as Appendix C. The 540-acre study area is comprised of 7 vegetation communities: freshwater marsh, southern cottonwood-willow riparian forest, coast live oak woodland, southern willow scrub, southern mixed chaparral, chamise chaparral, and Diegan coastal sage scrub. Two larval host plants were observed during the survey in various locations: dwarf plantain (Plantago erecta) and purple owl s clover (Castilleja exserta). Host plant locations are illustrated in Figure 4. Dwarf plantain was primarily found along the main access road and adjacent disturbed areas. Purple owl s clover was present in dense stands within natural openings in the chaparral and as scattered individuals along portions of the main access road. In addition, potential nectaring resources (e.g., popcorn flower [Cryptantha/Plagiobothrys spp.], fiddleneck [Amsinckia menziesii var. intermedia], California buckwheat [Eriogonum fasciculatum], and ground pink [Linanthus dianthiflorus]) were observed during the survey. Surveyors observed a total of 273 individuals during the 7 site visits comprised of 15 butterfly species; however, no QCB was observed. While the QCB flight season had a very limited number of QCB observed across its range, QCB host plants and nectaring resources were generally present in good numbers across the region. QCB host plants were generally restricted to several small open areas within dense stands of chaparral and along disturbed areas such as the main access road. Based on surveys conducted in a good habitat condition year, as 2015 appears to have been, the probability of QCB occurring on the site is considered low.
