Chapter 3 Results: Environmental Setting the sides of the Friant-Kern Canal. The Friant-Kern Canal is potentially under the jurisdiction of the USACE, the CDFG and the RWQCB. Calloway Canal and Emery Ditch are waterways within the BSA that contain non-native grassland species similar to those described above for non-native grassland. No open water was observed in these waterways at the time of the survey. However, these areas have features, such as a discernable bed, bank or channel and an ordinary high water mark, that indicate they are potentially under the jurisdiction of the USACE, the CDFG and the RWQCB. Developed/Ornamental Developed/ornamental areas consist of residential and commercial developments, paved roadways, compacted road shoulders, railroad tracks, and ornamental plantings including maintained turf grass. Common plant species observed in these areas include oleander (Nerium oleander), American sweet gum (Liquidambar styraciflua), olive (Olea europaea), and Mexican fan palm (Washingtonia robusta). 3.1.3.2. Common Animal Species Amphibians No amphibian species were observed during surveys. Amphibian species expected to occur in the BSA in the vicinity of the watercourses include the western toad (Bufo boreas), California treefrog (Pseudacris [Hyla] cadaverina), and Pacific treefrog (Pseudacris [Hyla] regilla). Reptiles The only reptile species observed in the BSA during the field surveys was the side-blotched lizard (Uta stansburiana). Other reptile species expected to occur in the BSA include western fence lizard (Sceloporus occidentalis), western whiptail (Aspidoscelis [Cnemidophorus] tigris), southern alligator lizard (Elgaria multicarinata), California whipsnake (Masticophis lateralis), and gopher snake (Pituophis catenifer). Birds Several resident bird species are expected to occur in the BSA, using the habitats throughout the year. Other species are present only during certain seasons. For example, the white-crowned sparrow (Zonotrichia leucophrys) is expected to occur in the BSA during the winter season and migrate north in the spring to breed during the summer. 26 State Route 58 Widening Project Biological Assessment
Chapter 3 Results: Environmental Setting Resident bird species observed in the BSA during surveys include killdeer (Charadrius vociferous), rock pigeon (Columba livia), mourning dove (Zenaida macroura), Anna’s hummingbird (Calypte anna), western scrub-jay (Aphelocoma californica), American crow (Corvus brachyrhynchos), northern mockingbird (Mimus polyglottos), European starling (Sturnus vulgaris), house finch (Carpodacus mexicanus), and house sparrow (Passer domesticus). Migrant bird species observed in the BSA during surveys include Say’s phoebe (Sayornis saya), western kingbird (Tyrannus verticalis), northern rough-winged swallow (Stelgidopteryx serripennis), cliff swallow (Petrochelidon pyrrhonota), barn swallow (Hirundo rustica), yellow-rumped warbler (Dendroica coronata), and white-crowned sparrow. Raptor species observed in the BSA include red-tailed hawk (Buteo jamaicensis), American kestrel (Falco sparverius), great horned owl (Bubo virginianus), and burrowing owl (Athene cunicularia). These species forage in the BSA and may nest in the BSA. Mammals Mammals observed in the BSA include desert cottontail (Sylvilagus audubonii), black-tailed jackrabbit (Lepus californicus), California ground squirrel (Spermophilus beecheyi), striped skunk (Mephitis mephitis), coyote (Canis latrans), San Joaquin kit fox, and red fox (Vulpes vulpes). Rodents that may occur in the BSA include house mouse (Mus musculus) and Botta’s pocket gopher (Thomomys bottae). Medium- to large-sized mammals expected to occur in the BSA include Virginia opossum (Didelphis virginiana), common raccoon (Procyon lotor), and American badger (Taxidea taxus). Bats occur throughout most of Southern California and may use some areas of the BSA as foraging habitat, however, no bats or sign of bats were observed during surveys. Most of the bats that could potentially occur in the BSA are inactive during the winter and either hibernate or migrate, depending on the species. Cavities in trees and man-made structures (such as bridges and culverts) provide potential roosting opportunities for bat species. Common bat species that may occur in the BSA include big brown bat (Eptesicus fuscus), California myotis (Myotis californicus), Brazilian free-tailed bat (Tadarida brasiliensis), and western pipistrelle (Pipistrellus hesperus).
