Projects in the Methow Valley
A
variety of people in the Methow Valley have implemented restoration
projects including individuals, families, ranchers, farmers,
non-profit groups, and county, state and federal agencies.
Restoration projects are varied and have included water conservation
efforts, fish and wildlife habitat enhancement, range improvements,
sustainable forest management, fire reintroduction, and road
and culvert improvements. Following are 2 examples of restoration
projects that have been implemented in the Methow Valley within
the last 6 years. An extensive list of projects and their
locations can be found on this site by clicking on the links

The
Chewuch River Restoration Project
From
1995-2001, the Pacific Watershed Institute (PWI), a local non-profit
group, has been implementing and monitoring restoration activities
on portions of the lower 25 miles of the Chewuch River in conjunction
with the Methow Valley Ranger District (MVRD) and the Washington
Department of Fish and Wildlife (WDFW). The Chewuch River is
home to endangered spring chinook salmon and steelhead and threatened
bull trout. Limiting factors for these fish in the Chewuch River
were identified as: lack of instream large woody debris (log
jams), loss of side channel habitat, and high levels of fine
sediment deposition. Restoration activities have sought to mitigate
for these factors by increasing quality habitat for these fish
species.
A
Brief History (Pre-Restoration)
In response to the 1948 and 1972 floods of the Chewuch River,
many log jams were removed from the river and several areas
of the lower 25 miles of the river were stabilized with riprap
and dikes. Logging in riparian areas decreased the amount
of wood available for recruitment into the stream. These actions
contributed to a decrease in quality habitat for resident
and migratory fish in many ways.
Large
woody debris (LWD) or log jams serve many functions in the
river ecosystem. The scouring action of the river around LWD
carves out pools that provide resting and hiding cover for
fish. These pools serve as depositional areas for gravel,
which is important for spawning. Large woody debris also slows
the flow of the stream, which results in less bank erosion
and less sediment in the river. This is important because
sediment can smother fish eggs before they hatch, bury important
spawning gravel, fill in important pool and side channel habitat,
and lead to increased stream temperatures. Sediment loads
in the Chewuch have been exacerbated by road construction
activities, streamside recreation, natural erosion and stream
channelization. The channelization of portions of the river
has also resulted in fewer active side channels, which are
important as fish rearing habitat.
Restoration
Efforts
To mitigate for these factors, habitat restoration projects
were implemented by PWI, MVRD and WDFW within the river and
in adjacent riparian areas. These projects included addition
of 17 instream LWD structures, the reestablishment of 2 side
channels, revegetation of 2.5 miles of riverbank, relocation
of selected streamside roads and camping areas, fencing of
¾ mile of sensitive riparian area and planting 20-30 acres
of native plants in disturbed areas. Post-project monitoring
is helping to assess the impacts of these restoration activities.
Project
activities took place on USFS, WDFW, DNR and private land
and funding was provided by the Washington State Jobs for
the Environment (JFE) program, the U.S. Fish and Wildlife
Service Grant Challenge Cost Share Program, and the U.S. Fish
and Wildlife Jobs in the Woods (JITW) restoration program.
This project and other Pacific Watershed Institute projects
have provided much needed jobs and training to 9 local displaced
timber workers and 8 other local people.
In addition
to this work, the Forest Service has been closing and obliterating
roads, fencing riparian areas, and reorganizing streamside
campgrounds in the Chewuch watershed.
Sustainable
Forest Management in the Rendezvous area
of upper Cub Creek
The Pacific
Watershed Institute (PWI), The Methow Conservancy (MC), and
Partnership for a Sustainable Methow (PSM), all local non-profit
groups, have been working on private land with 9 private landowners
in the Rendezvous area to improve forest health. This project
began in 1999 and will continue through 2003.
A
Brief History (Pre-Restoration)
Much
of the upper Cub Creek watershed was once predominantly open,
park-like stands of large Ponderosa pines and bunchgrasses
on the south facing slopes and mixed pine, douglas fir forest
on the north facing slopes. All of this was interspersed with
riparian areas of aspen, cedar, alder and shrubs. Fire played
an integral part in this ecosystem and served to: reduce fuel
levels, keep insect levels in check, maximize plant and wildlife
diversity by creating a mosaic of habitat types, and open
up the understory to allow the regeneration of shrubs, grasses,
and shade intolerant ponderosa pines and aspens.
Fire suppression
and past logging in the Rendezvous have resulted in an overstocked,
unhealthy forest comprised mostly of small-diameter douglas
firs. In the Methow Valley, douglas firs are usually predominant
on north facing slopes and their density is kept in check
by fire. Since the advent of fire suppression in the early
1900's, douglas firs have encroached on ponderosa pine and
aspen stands and the forest understory is lacking in shrubs
and grasses. The resulting decrease in plant diversity typically
results in a decrease in bird and wildlife diversity. The
densely stocked forest reduces the amount of precipitation
and snow reaching the ground and reduces the water storage
for nearby tributaries and the rivers downstream, which has
an effect on human and fish populations. Increased fuel loads
also increase the risk of catastrophic fire, which poses a
threat to local homes and wildlife. Similar forest conditions
exist in much of the Methow Valley's mid-elevation forests.
Restoration Efforts
PWI,
MC and PSM have been implementing restoration activities to
improve forest health in the Rendezvous area. Projects have
included selectively thinning 200 acres of dense, small diameter
douglas fir, underburning selected
areas with prescribed fire, and creating a mosaic of habitat
types to benefit wildlife. Partnership for a Sustainable Methow
is researching economically viable methods to use the large
amounts of small diameter wood resulting from this project
and future sustainable forestry activities. In addition to
the forestry activities, the Pacific Watershed Institute has
upgraded roads and culverts in the Rendezvous area to reduce
sediment into nearby streams, which are the headwaters for
Cub Creek, a major tributary and sediment contributor into
the Chewuch River.
Funding
for these projects was provided by the U.S. Fish and Wildlife
Jobs in the Woods (JITW) restoration program, the Interagency
Committee for Outdoor Recreation (IAC), and contributions
from Rendezvous landowners.
