188.8.131.52 Other Sensitive Biological Resources
San BuenaVentura State Beach downcoast from the Surfer's Point sand placement site
has been reported as regularly supporting grunion spawning (Blunt 1980).
2.3.6 Oxnard Shores
Figure 2-5 shows the biological resources in the vicinity of the Oxnard Shores sand
placement site. The intertidal substrate in this are consists entirely of sand.
The subtidal substrate off Oxnard Shores consists entirely of sand. There are no kelp
beds in the vicinity of Oxnard Shores.
The Santa Clara River mouth is located about 1.5 miles north of the Oxnard Shores
beach placement site. The Santa Clara River mouth is a Ventura County ESH and a
State of California Natural Preserve. A barrier beach forms at the mouth during periods
of low flow. The berm is usually breached by high winter flows and/or wave
overwashing after which the inlet stays open for varying lengths of time. The 133-acre
estuarine/marsh habitat supports high intensity bird utilization including nesting by the
federal and state endangered California least tern. Tidewater gobies and southern
steelhead both occur in the Santa Clara River.
McGrath Lake is a small (about 10 acres) wetlands area that was part of the historic
Santa Clara River estuary and delta system. McGrath Lake is located just north of the
Oxnard Shores beach placement site. McGrath Lake has been designated an ESH by
the County of Ventura because it includes sensitive marsh and dune habitats. There is
no ocean inlet, although waves occasionally overwash the beach berm. California least
terns nest from the Santa Clara River mouth to McGrath Lake (CDFG 2000). Western
snowy plovers also nest at McGrath Lake (M. Wehtje, CDFG, personal communication
184.108.40.206 Sensitive Species
California least terns nest in the area between the Santa Clara River mouth and
McGrath Lake immediately upcoast from the Oxnard Shores beach placement site.
In 1999, this colony consisted of between 13 and 18 pairs, down from 43 pairs in 1998
