What is the Oregon Plan?
The Oregon Plan for Salmon and Watersheds is a broad-based effort of citizens, local watershed groups, the State of Oregon, and federal agencies to restore healthy salmon populations and their watersheds. The most important part of the Plan is the idea that people working together, with the support of state and local government, can do more to help fish than could be accomplished by a strict regulatory approach. The Plan has been in effect for about three years. Hundreds of projects designed to improve stream habitat and watershed conditions have been completed. Support for watershed groups, SWCD’s, and landowners has brought people together to develop stream restoration plans tailored to the needs of the local community. For more information: Oregon Plan
for Salmon and Watersheds Monitoring Program Activities Monitoring programs under the Oregon Plan for Salmon
and
Watersheds are designed to assess the status and trends in fish
populations and
aquatic habitat in Stream habitat assessment is conducted by the Aquatic Inventories Project. The sampling is targeted at two spatial scales, the monitoring area and coho population area. Monitoring areas are comprised of stream habitat in large geographic areas that supports populations of coho, Chinook, and chum salmon, and steelhead and cutthroat trout. Population scale sampling focuses only on stream habitat within individual basins that support juvenile and adult coho salmon. Surveyors collect information on channel size, flow, substrate composition, large wood, habitat complexity, and riparian characteristics.
Monitoring Area
Assessment
Stream surveys are designed to describe status and trends in
habitat conditions in seven monitoring areas in coastal and lower
Columbia
River basins (Figure 1). The sample
sites in coastal basins are distributed throughout all streams that
have a
basin size larger than 0.6km2; in the monitoring areas in
the lower Samples are selected independently between monitoring areas from a 1:24,000 stream map and will incorporate a rotating panel design structure enabling site visitations on an annual and cyclical basis. For more information about the rotating panel design and sampling structure, please visit the EPA Aquatic Resource Monitoring website (http://www.epa.gov/nheerl/arm/). Fifty habitat sites are visited in five coastal monitoring areas (North Coast, Mid-Coast, Mid-South, Umpqua, and The objective of the survey design is to determine the status of selected habitat variables within a 30% precision, to permit trend detection over 5 year increments. We will determine the status and trend in habitat conditions for each of 21 independent populations and in aggregate for dependent populations within each of 4 monitoring areas.
We will sample each of
the independent populations once during every 5 year period. Sampling order will be randomly determined
for each 5 year period starting in winter 2007-2008. Dependent
populations will be treated similarly, but will
be grouped
together spatially and sampled in aggregate. Some
of the small independent population units will have
the adjacent
dependent populations as part of their sample frame.
Figure 2 and Table
1 display the 20
population sample frames, referred to as population blocks.
Five year analyses will aggregate the total number of sites sampled within each of 21 populations and 4 groups of dependent populations. Sample size in each population block will be adjusted for the second 5-year period based on sensitivity analysis of the habitat variables. Table 1. Population units within each sampling block. A “+” indicates addition of adjacent dependent populations to small independent population.
Contact: ODFW https://nrimp.dfw.state.or.us/crl/default.aspx?pn=AI Juvenile Salmon Population Census Divers will snorkel pool habitats to count juvenile salmon. Over time, these counts help us understand trends in the abundance and distribution of juvenile salmonids. At some of the sites, more precise population estimates will be made for juvenile coho, cutthroat, and steelhead. Survey sites will vary in length. Field crews will spend about one day at each site over the summer sampling period. Contact: ODFW http://oregonstate.edu/dept/pacrim/index.htm
Counts of spawning adult salmon are a key indicator of abundance. A team of one or two surveyors will visit each potential site once during the summer to mark the boundaries of the survey and collect data on stream size, availability of spawning gravel, and possible barriers to fish-passage. Each survey covers about one mile of stream. Starting with the fall spawning migration, and continuing through early winter, crews will visit each site about once a week to count the salmon.

Salmonid Life Cycle Monitoring Project: Smolt Trapping In 1998, as part of the Oregon Plan for Salmon and Watersheds (formerly the Coastal Salmon Restoration Initiative) the Oregon Department of Fish and Wildlife (ODFW) began a program to monitor survival and downstream migration of salmonid fishes (Oncorhynchus spp.) As a part of this program the Salmonid Life-cycle Monitoring project developed three objectives; 1) estimate abundance of adult salmonids and downstream migrating juvenile salmonids, 2) estimate the marine and freshwater survival rates for coho salmon (Oncorhynchus kisutch) and 3) evaluate the effects of habitat modification on the abundance of juvenile salmonids in Cummins and Tenmile Creeks. Contact: ODFW http://oregonstate.edu/Dept/ODFW/life-cycle/index.html Stream Health – Biotic Index Measurement Measurements of aquatic insects, aquatic plants, water quality, fish communities, and habitat are combined to create an integrated assessment of stream condition. The length of stream sampled ranges from about one-quarter to one-half a mile. Crews spend a day at each site. Contact: Oregon Department of Environmental Quality |
