SUMMARY: The Board will consider authorizing staff to retain
the Ventana Wilderness Society (VWS) to continue the District’s avian
(bird) habitat monitoring program on
the Carmel River during calendar year 2004. This work will continue the
monitoring of bird life along the river conducted since 1992, including the
collection of data on the use of the Carmel River riparian corridor during bird
migration and breeding seasons. Work will be as shown in Exhibit 5-A.
RECOMMENDATION: Authorize the General Manager to enter into
a contract with the Ventana Wilderness Society for avian habitat monitoring
work along the Carmel River at a cost not to exceed $15,600. The Administrative Committee considered this
matter at its April 13, 2004 meeting and recommended _________________.
IMPACTS ON STAFF AND RESOURCES: Funds to conduct the District’s 2004
wildlife monitoring program are proposed to be included in the draft FY
2004-2005 budget under Project Expenditures for Program 2.1 (Riparian Habitat
Mitigations, Wildlife monitoring).
Estimated costs for the scope of work as shown in Exhibit 4-A total
$15,600. Mileage expenses are included
in this not-to-exceed amount. This work will be performed under the direction
of the District’s Riparian Projects Coordinator.
BACKGROUND:
Avian (bird) use of riparian habitat provides an excellent indicator of
wildlife habitat value. In 1992, the
District established permanent sampling locations for avian species monitoring
at several sites along the Carmel River.
The purpose of this program is to
measure bird use at the monitoring sites, thus providing an indication
of changing patterns of habitat values in the District’s restoration project
areas. Information on bird populations
and avian species diversity collected as part of the District’s Mitigation
Program has assisted in documenting trends in the response of wildlife
populations to habitat enhancements implemented by the District. Locations of the monitoring sites are shown
in Exhibit 5-B. Data collected from
1992 through 2003 are summarized in the graphs shown in Exhibit 5-C. The two major dips in bird counts that can be seen in the graphs
are likely the result of the reduction and disturbance of riparian habitat
caused by the high river flows and erosion in 1995 and 1998. The higher bird counts following the two
dips indicate a recovery of the extent and health of the riparian habitat. The District’s riparian vegetation planting
and irrigation activities promote growth and health of riparian vegetation, and
are a likely reason for the higher bird counts.
In addition to continuing the bird counts and
avian species diversity index monitoring protocols established in 1992, the VWS
will continue monitoring a series of mist netting sites within District
riparian habitat enhancement areas. The
VWS sampling will span the spring, summer and fall migration and breeding
seasons for a comprehensive look at patterns of wildlife use in District
planting areas. Long-term monitoring of
the same sampling locations provides an indication of the overall changes in
wildlife habitat values resulting from the District’s planting, irrigation, and
erosion protection efforts.
