► animals fully protected in California under the California Fish and Game Code, <br /> ► plants listed as Endangered or Rare under the California Native Plant Protection Act, and <br /> ► plants on CNPS Lists lA(plants presumed extinct in California), 113 (plants rare,threatened, or endangered in <br /> California and elsewhere), or List 2 (plants rare,threatened, or endangered in California but more common <br /> elsewhere). <br /> Recent and historical reports of special-status species in the vicinity of the project area were identified through a <br /> search of the CNDDB (2006)and the CNPS Inventory (CNPS 2006). The CNDDB is a statewide inventory <br /> managed by DFG,which is continually updated with the locations and condition of the state's rare and declining <br /> species and habitats. Although the CNDDB is a reliable tool for site-specific information on sensitive biological <br /> resources, it should be noted that it contains only those records that have been submitted to DFG and is not <br /> always up to date or comprehensive. <br /> A CNDDB and CNPS database search was conducted for the Manteca,Avena,Lathrop,Peters, Stockton East, <br /> Stockton West, Salida,Ripon, and Vernalis USGS 7.5-minute quadrangles. Tables 4.5-1 and 4.5-2 list the special- <br /> status species potentially existing in the project area,based on a review of the CNDDB search,the CNPS <br /> inventory, and the reconnaissance-level surveys. <br /> Special-Status Plants <br /> A total of 13 special-status plants have been known to exist or have potential to exist in the project area. The <br /> regulatory status,habitat requirements, and potential for existence of each species are provided in Table 4.5-1. <br /> Each species is also discussed further in the text that follows the table. Two additional species,round-leaved <br /> filaree(Erodium macrophyllum) and palmate-bracted bird's beak(Cordylanthus palmatus),historically grew in <br /> the vicinity of the project area. However,these species require clay soils not found in the area. Therefore,these <br /> plants do not have potential to exist in the project area and are not included in Table 4.5-1. <br /> Table 4.5-1 <br /> Special-Status Plants Known or with Potential to Occur in the Proposed Project Area <br /> Species StatusHabitat and Blooming Period Potential for Occurrence <br /> USFWS DFG CNPS <br /> Suisun Marsh aster 113 Endemic to the Sacramento—San Possible.California Natural <br /> Aster lentus Joaquin Delta;generally occurs in Diversity Database(CNDDB)lists <br /> marshes and swamps;often occurs occurrences near Stockton and in <br /> along sloughs,at 0-3 meters in the Lathrop quadrangle. <br /> elevation.
