Aquatic Conservation Strategy
The Aquatic Conservation Strategy was developed to
restore and maintain the ecological health of watersheds
and aquatic ecosystems contained within them on public
lands. The strategy will protect salmon and steelhead
habitat on Federal lands managed by the Forest Service
and Bureau of Land Management.
The Aquatic Conservation Strategy is designed to meet
the following objectives:
- Maintain and restore the distribution, diversity,
and complexity of watershed and landscape-scale
features to ensure protection of the aquatic
systems to which species, populations, and
communities are uniquely adapted.
- Maintain and restore spatial and temporal
connectivity within and between watersheds.
Lateral, longitudinal, and drainage network
connections include flood plains, wetlands, up
slope areas, headwater tributaries, and intact
refugia. These lineages must provide chemically
and physically unobstructed routes to areas
critical for fulfilling life history requirements
of aquatic and riparian-dependent species.
- Maintain and restore the physical integrity of
the aquatic system, including shorelines, banks,
and bottom configurations.
- Maintain and restore water quality necessary to
support healthy riparian, aquatic, and wetland
ecosystems. Water quality must remain in the
range that maintains the biological, physical,
and chemical integrity of the system and benefits
survival, growth, reproduction, and migration of
individuals composing aquatic and riparian
- Maintain and restore the sediment regime under
which an aquatic ecosystem evolved. Elements of
the sediment regime include the timing, volume,
rate, and character of sediment input, storage,
- Maintain and restore in stream flows sufficient
to create and sustain riparian, aquatic, and
wetland habitats and to retain patterns of
sediment, nutrient, and wood routing (i.e.,
movement of woody debris through the aquatic
system). The timing, magnitude, duration, and
spatial distribution of peak, high, and low flows
must be protected.
- Maintain and restore the timing, variability, and
duration of flood plain inundation and water
table elevation in meadows and wetlands.
- Maintain and restore the species composition and
structural diversity of plant communities in
riparian zones and wetlands to provide adequate
summer and winter thermal regulation, nutrient
filtering, appropriate rates of surface erosion,
bank erosion, and channel migration, and to
supply amounts and distributions of coarse woody
debris sufficient to sustain physical complexity
- Maintain and restore habitat to support
well-distributed populations of native plant,
invertebrate, and vertebrate riparian-dependent
The components of the Aquatic Conservation Strategy
are Riparian Reserves, Key Watersheds, Watershed
Analysis, and Watershed
See Riparian Reserves in
the Land Use Allocation
A system of Key Watersheds that serves as refugia is
crucial for maintaining and recovering habitat for
at-risk stocks of anadromous salmonids and resident fish
species. These refugia include areas of high quality
habitat and areas of degraded habitat. Key Watersheds
with high quality conditions will serve as anchors for
the potential recovery of depressed stocks. Those of
lower quality habitat have high potential for restoration
and will become future sources of high quality habitat
with the implementation of a comprehensive restoration
There are 2 types of Key Watersheds - Tier 1 and Tier
2. Tier 1 watersheds contribute directly to conservation
of at-risk anadromous salmonids, bull trout, and resident
fish species. They also have a high potential of being
restored as part of a watershed restoration program. Tier
2 watersheds do not contain at-risk fish stocks, but they
are important sources of high quality water.
Key Watersheds overlay portions of all land use
allocations in the District and place additional
management requirements or emphasis on activities in
those areas. The Bear/Marten watershed is the only Key
Watershed that is entirely in the Eugene District. This
watershed is part of the Central Cascade AMA and overlays
both Matrix and Riparian Reserve land use allocations.
Key Watersheds and District ownership within them:
|N. Fork Smith River
|Upper Lobster Creek
|Upper Smith River
See Map 2-19 in the PRMP/FEIS for location of Key
The noninterchangeable component of the Allowable Sale
Quantity, attributable to Key Watersheds, is 460,000
cubic feet. Identification of this component was required
by the SEIS Record of Decision, pages E-19 and E-20.
||Prior to further resource
management activity, including timber harvest,
prepare watershed analyses in Key Watersheds.
Until watershed analyses can be completed,
proceed with minor activies, such as those
categorically excluded under the National
Environmental Policy Act (NEPA) regulations
(except timber harvest), if they are consistent
with Aquatic Conservation Strategy objectives.
Apply Riparian Reserve management
||Reduce existing road mileage
within Key Watersheds. If funding is insufficient
to implement reductions, neither construct nor
authorize through discretionary permits a net
increase in road mileage in Key Watersheds.
||Give highest priority to
watershed restoration in Key Watersheds.
See Watershed Analysis
(toward the end of this section) and the SEIS/ROD (see Appendix A) for
Watershed restoration will be an integral part of a
program to aid recovery of fish habitat, riparian
habitat, and water quality. The most important components
of a watershed restoration program are control and
prevention of road-related runoff and sediment
production, restoration of the condition of riparian
vegetation, and restoration of in-stream habitat
complexity. Other restoration opportunities include
meadow and wetland restoration and mine reclamation.
||Prepare watershed analyses and
plans prior to restoration activities.
||Focus watershed restoration on
removing some roads and, where needed, upgrading
those that remain in the system.
||Apply silvicultural treatments
to restore large conifers in Riparian Reserves.
||Restore stream channel
complexity. In-stream structures will only be
used in the short-term and not as a mitigation
