Ms. Kerry Sullivan <br /> April 8, 1992 <br /> Page 15 <br /> Page 4.7- 19 Greater Sandhill Crane <br /> It is very possible that during normal rainfall years this subspecies utilizes the Tracy Lakes basins <br /> for both feeding and roosting, however, this assumption could not be confirmed during the <br /> preparation of this document. <br /> C202 <br /> This statement is conjecture about the presence of the Greater Sandhill Crane on the property. But <br /> there is every reason to believe that the Management Plan, in expanding seasonal marshes,will provide <br /> additional habitat suitable for the Crane's use. <br /> Page 4.7 - 20 Other protected Species <br /> Two protected amphibian species that most likely existing on the site in recent time are the red- <br /> legged frog (Rana aurora) and the California tiger salamander (Ambystoma tigrinum 0203 <br /> californiense). They are both pond spawning species. <br /> Once again,this is conjecture about the presence of these species. <br /> Page 4.7 - 20 <br /> The valley elderberry longhorn beetle (Desmocerus californicus dimorphus), a federal-listed <br /> threatened species, occurs in San Joaquin County where elderberry plants (Sambucus sp.) <br /> comprise part of the local riparian community. Several stem sections were closely examined for C204 <br /> signs of the beetle larva, but none were found. However, a survey for the adults in early <br /> summerwould be needed to further verify its presence or absence on the project site. <br /> Evidence of usage is visible on the stems of the elderberry plant itself; therefore,since one were found, <br /> presumably none exist. <br /> Page 4.7 - 21 <br /> The tree and/or bush clearing operation in 1989 resulted in the loss of 12.5 acres of the scarcest <br /> biological community in San Joaquin County and the Central Valley which is the old growth <br /> foothill/riparian woodland community. C205 <br /> The Nature Conservacy's preserve on the Consumnes River is significantly better habitat. It continues to l <br /> flood naturally unlike Brovelli Woods. The actual amount of forest cleared was less than ten acres. The <br /> Management Plan calls for replanting and re-establishing riparian woodlands on twenty acres along the <br /> Mokelumne River previously cleared and leveled by the former owners. <br /> Page 4.7 - 21 <br /> The creation of permanent lakes would remove a potential foraging habitat for the hawk. <br /> Presently, the combination of shoreline,coupled with the lakebed, provides a blend of riparian <br /> brush and lakebed weed growth which creates prime rodent habitat most likely used by the <br /> Swainson's hawk. While it is recognized that the proposed plan creates more shoreline than C206i <br /> presently exists, this new shoreline involves an open water/plant edge ecotone which would not <br /> be near as productive for rodents as existing conditions. <br /> This statement is factually incorrect. The Management Plan discusses the seasonal marshes we are <br /> proposing to create in the fingers of the lakes. <br /> III-13C <br />
