SUMMARY: The Board will consider authorizing staff to
retain the Ventana Wildlife Society (VWS) to continue the District’s avian
(bird) habitat monitoring program on the Carmel River during calendar year
2007. 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 3-A.
RECOMMENDATION: District staff recommends that the Board
authorize the General Manager to enter into a contract with the Ventana
Wildlife Society for avian habitat monitoring work along the Carmel River at a
cost not to exceed $4,152, with the scope of work, costs and schedule as shown
in Exhibit 3-A.
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 3-B. An
example of the data collected from 1992 through 2006 at the Schulte Restoration
Project is shown in Exhibit 3-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 avian species monitoring Avian Guild Census (Spring and Fall observations of birds at nine locations along the Carmel River and calculation of the Species Diversity Index for each location) has been carried out annually from 1992 through 2006. Tasks 1 and 2 are to conduct the Species Diversity Index (SDI) monitoring, and Task 3 is to prepare a report on results of the SDI monitoring activities. The costs for Tasks 1, 2, and 3 total $3,003.04, as shown in Exhibit 3-A.
This year’s proposed monitoring includes a protocol known as Monitoring Avian Productivity and Survivorship (MAPS) (Tasks 4 and 5). This protocol includes the mist-netting of birds at three key sites along the river to track avian population size and productivity. The costs for Tasks 3 and 4 would be shared among the District ($1,148.74, or approximately 21 percent of the $6,689.39 total cost), VWS ($3,868.30) and the U.S. Fish and Wildlife Service (USFWS) Neotropical Migratory Bird Conservation Act ($1,672.35), as shown in Exhibit 3-A. The District has contracted with VWS for MAPS monitoring in 2000, 2002, 2003 and 2004 but did not request funds for MAPS in 2005 and 2006 because of budget constraints. The impact of not performing the MAPS monitoring this year is that there would not be information on avian population size and productivity for 2007.
The scope includes collection and analysis of
Species Diversity Index data and MAPS data as well as the preparation of both
2007 annual reports.
IMPACTS ON STAFF AND RESOURCES: Estimated MPWMD costs for the scope of work
as shown in Exhibit 3-A total
$4,151.78. Mileage expenses are included
in this not-to-exceed amount. The scope
of work would be the same as was conducted in 2004 but at a significantly lower
cost because of the sharing of the costs among the District, VWS, and USFWS
funds for the MAPS work. In FY
2004-2005, the contract not-to-exceed amount was $15,600. The savings reflect the sharing of the cost
of the MAPS protocol described above ($13,700 in 2004). For the
2007 contract, the not-to-exceed amount will be $4,152. Although services under
the contract (Task 1: Spring 2007
Transect Monitoring) will begin in the current fiscal year, billing for all
work done under the contract will be submitted during FY 2007-2008. The budget for FY 2007-2008 has not been
adopted, but staff will propose including funding for this contract. The work will be performed under the
direction of the District’s Riparian Projects Coordinator.
