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
2005. 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. This monitoring is conducted in accordance
with the Mitigation Program for the District’s Water Allocation Program
EIR. The proposed scope of work, costs,
and schedule are as shown in Exhibit 2-A.
RECOMMENDATION: District staff recommends that the Board
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 $1,900, with the scope of work, costs and schedule as
shown in Exhibit 2-A. The Administrative Committee considered this
matter at its April 4, 2005 meeting and voted 3 to 0 to recommend approval.
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 2-B. An
example of the data collected from 1992 through 2004 at the Schulte Restoration
Project is shown in Exhibit 2-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.
The VWS sampling will span the spring and fall migration and breeding seasons for a 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.
The proposed reduction in scope for avian monitoring in 2005 is to not conduct a protocol known as Monitoring Avian Productivity and Survivorship (MAPS). This protocol includes the mist netting of birds at four key sites along the river to track avian population size and productivity. The District has contracted with VWS for MAPS monitoring in 2000, 2002, 2003 and 2004. The impact of not performing the MAPS monitoring this year is that there will not be information on avian population size and productivity for 2005. However, the fundamental avian species monitoring that has been carried out annually from 1992 through 2004 (Spring and Fall observations of birds at 20 locations along the Carmel River and calculation of the Species Diversity Index for each location) is proposed to be continued in 2005.
IMPACTS ON STAFF AND RESOURCES: Estimated costs for the scope of work as
shown in Exhibit 2-A total
$1,900. Mileage expenses are included in
this not-to-exceed amount. The scope of
work has been reduced significantly from the work performed in previous years
in recognition of likely budget limitations in FY 2005-2006. In FY
2004-2005, the contract not-to-exceed amount was $15,600. The savings reflect the cost of the MAPS
protocol described above ($13,700 in 2004). This year, the not-to-exceed amount is
proposed to be $1,900. The scope
includes collection and analysis of Species Diversity Index data and
preparation of the 2005 annual report.
This work will be performed under the direction of the District’s
Riparian Projects Coordinator.
