Interagency
watershed analysis
A
multi-agency synthesis of history, resources, and potential directions,
completed in 1997. An excellent source of a wide variety of
information; assembled in a short time as
required by the Northwest Forest Plan, and not intended as a basis for
scientific study (146 p + maps).
Swiss needle
cast survey maps and relevant GIS information are contained in the Ph.D.
thesis by P.H. Rosso (2001).
Ecology
reconnaissance plots
The watershed
has about 30 plots for developing and testing the vegetation-association
maps—500 m2 with herb, shrub, and tree species, site
index, snags, herb biomass, and soil depth; filed electronically.
Large plots
with more detail including dbhs, crown information, and decomposing logs;
filed electronically.
From 1947-1957 and in 1979 and 1992 for all
major streams, including gradients, flow, canopy closure, temperature, fish
species presence and abundance, spawning gravels, invertebrate
abundance, and more—with detailed maps.
Mass movement—associated with roads and
plantations and, where visible, in older stands—was surveyed on federal lands
in the entire watershed by interpreting aerial photographs.
Continuing
surveys from 1980s-1990s; filed electronically.
Many areas were surveyed for Poa laxiflora, a threatened
species.
Completed on
about 50 harvest units for mollusks, as required by the Northwest Plan.
Oregon Climate Service (www.ocs.orst.edu) has data
online for the Alsea fish hatchery weather dating back to 1952. Two
fire-weather, RAWS sites are inside the watershed. We expect to find older local data as
well.
Data on
old-growth and younger fire-origin stands in the eastern part of the
watershed, including ages, densities, and growth rates.
Timber cruise
map for 1900
We have a
copy of a map of the Oregon Coast Range timber resources made by a private
timber cruiser in 1900.
We have seen
a binder with details on proposed layouts of old units.
The county
has been monitoring weeds on Forest Service roads for years.
Site-preparation
experiment
One of 5 Coast Range blocks (142 acres) is
on Five Rivers in an experiment comparing 6 site-preparation methods (spot
clearing, aerial spraying, broadcast burning, slashing and burning,
spraying and burning, and a control), with detailed effects on trees, shrubs,
and herbs (Stein 1995).
Vegetation-management experiment
One of 4
Coast Range blocks (237 acres) directly adjacent to Five Rivers in an
experiment comparing 7 release options (2 herbicides, 3 manual, and 1 combined),
with detailed effects on trees, shrubs, and herbs (Stein 1999).
Site preparation, planting stock experiment
One of 6 replicates is in the watershed
(Pitchfork unit) comparing 4 site-preparation methods and 7 different planting
stocks, with and without browse protection—unpublished, but data
available from Bill Stein.
Stumps in 20 managed units in the lower
two-thirds of the Five Rivers watershed were analyzed in detail for fire
history—OSU Ph.D. thesis by Peter Impara (1998).
Pollen and
charcoal records
Dating back
43,000 yr, from Little Lake sediments, just downwind from Five Rivers (Long et al. 1998).
We have
recently learned that 100s of cubic feet of historical files submitted by the
Forest Service are stored in the federal archive in Seattle, WA.
