Draft Environmental Impact Report Page IV.H-12 <br /> Forward Inc. Landfill Expansion Project <br /> The Swainson's hawk was historically regarded as one of the most numerous raptors in the <br /> state. The dramatic decline in the population of the Swainson's hawk has been attributed to the <br /> loss of native nesting and foraging habitat, and more recently to the loss of suitable nesting <br /> trees. This loss of nesting habitat within riparian areas has been accelerated by flood control <br /> practices and bank stabilization programs (CDFG undated[b)). The loss of agricultural lands to <br /> various residential and commercial developments is a serious threat to Swainson's hawks <br /> throughout California. Additional threats are habitat loss due to riverbank protection projects, <br /> conversion from agricultural crops that provide abundant foraging opportunities to crops such <br /> as vineyards and orchards which provide fewer foraging opportunities, shooting, pesticide <br /> poisoning of prey animals and hawks on wintering grounds, competition from other raptors, <br /> and human disturbance at nest sites. <br /> The non-native grasslands and disced fields within the study area could be used for foraging by <br /> Swainson's hawk. A Swainson's hawk nest site was documented in 2002 along the north <br /> branch of the south fork of Littlejohn's Creek near the northeast corner of the Forward Landfill <br /> property (CNDDB 2008). There are four additional documented nests within three miles of the <br /> project site (CNDDB 2008). <br /> White-tailed Kite <br /> White-tailed kites (Elanus leucurus) inhabit open grasslands and savannahs.They breed in a <br /> variety of habitats including grasslands, cultivated fields, oak woodlands and suburban areas . <br /> where prey is abundant. Nests are typically built in trees near a water source and may occur in <br /> suburban areas with adjacent open areas with abundant prey. White-tailed kite nesting sites are <br /> designated as fully protected under of the California Fish and Game Code (CFGC)14. This <br /> species receives additional protection under the MBTA and Migratory Bird Treaty Reform Act <br /> (MBTRA). No critical habitat has been designated for this species. <br /> A White-tailed kite has been observed foraging over the property during biological <br /> reconnaissance surveys in 2008 (WRA 2009). This species may nest in suitable trees on <br /> properties adjacent to the study area. <br /> Other Special-Status Species <br /> Burrowing Owl - <br /> The burrowing owl (Athene cunicularia) is designated a California Species of Special Concern by <br /> the CDFG. This species receives additional protection under the MBTA and the CFGC15 <br /> Burrowing owls range throughout the Central Valley, the inner and outer coastal regions, <br /> portions of the San Francisco Bay Area, the southern California coast from southern California <br /> to the Mexican Border, the Imperial Valley, and in portions of the desert and high desert <br /> habitats in southeastern and northeastern California. <br /> Burrowing owls require habitat with three basic attributes: open, well-drained terrain; short, <br /> sparse vegetation; and underground burrows or burrow facsimiles.Throughout their range <br /> burrowing owls occupy grasslands, deserts, sagebrush scrub, agricultural areas (including <br /> pastures and untilled margins of cropland), earthen levees and berms, coastal uplands, urban <br /> vacant lots, and the margins of airports, golf courses,and roads (Haug, et al. 1993). Burrowing <br /> owls rely on burrows excavated by fossorial mammals or reptiles, including ground squirrels, <br /> badgers,badgers, skunks, foxes and coyotes.
