which serve as hosts for developing larvae of Lytta. Adult Lytta beetles are <br /> most frequently observed in March and April, but there are also scattered <br /> collection dates during May and June. Museum collection records include <br /> specimens from several locations in San Joaquin County. <br /> California Hibiscus. <br /> The California Hibiscus (HIbiscus califoraicus) is a member of the plant <br /> family Malvaceae. It is recognized as a category 2 candidate at the federal <br /> level, and is on list 1B of the California Native Plant Society. This annual <br /> lives in freshwater marshes, sloughs, and riparian areas between Contra Costa <br /> and Butte counties. It is best known from the Sacramento and San Joaquin <br /> Rivers, but also occurs throughout the Delta. The California Hibiscus flowers <br /> in August and September. I <br /> ENVIRONMENTAL SETTING <br /> Two sites between Austin and Newcastle Roads near Stockton were sur- <br /> veyed. Both sites lie south of the existing CYA prison and next to the exist- <br /> ing landfill for the City of Stockton. <br /> Both the surplus CYA parcel and Brocchini property are ag lands that are <br /> in cultivation. Observed plant communities on surrounding properties are <br /> primarily cultivated ag lands or ruderal grassland. Along the North Branch, <br /> South Fork of Little Johns Creek, which forms the northern property boundary <br /> of the Brocchini parcel, there is a small remnant of riparian vegetation, with <br /> a few scattered oaks, but ag lands encroach upon most of the creek embankment. <br /> Prominent plow furrows are evident at both sites. <br /> SURVEY METHODS <br /> The habitat assessment and status surveys were conducted on September <br /> 5th at both the Brocchini and the surplus CYA properties. Because of the <br /> timing of my site visit, I could not survey directly for either the Valley <br /> Elderberry Longhorn beetle or the Molestan Blister beetle. Rather, during my <br /> field surveys, I focused on identifying potential areas of suitable habitat <br /> for these species within and adjacent to the project site. Because the timing <br /> of my visit was within the flowering period for the California Hibiscus, I <br /> searched potentially suitable areas of habitat for this species. <br /> The habitat assessment for the VELB consisted of surveying both parcels <br /> for elderberry plants. The creek and an off-site pond, located on CYA proper- <br /> ty near the crossing of the creek at Austin Road, were the most likely areas <br /> to support the elderberry. Status surveys for the California Hibiscus were <br /> also concentrated in these portions of the project site and adjacent off-site <br /> areas. <br /> The habitat assessment for the Blister beetle concentrated on surveying <br /> for their suspected hosts, Digger bees of the genus Anthophora, and flowers <br /> (primarily legumes, composites, and poppies) known to be visited by the bee- <br /> tles or Digger bees. <br /> Austin Road Landfill Report Page 2 <br />
