From the forest to the sea : a story of fallen trees

Creator:: Maser, Chris, Tarrant, Robert F., Trappe, James M., and Franklin, Jerry F.
Abstract:: Large fallen trees in various stages of decay contribute much-needed diversity of ecological processes to terrestrial, aquatic, estuarine, coastal beach, and open ocean habitats in the Pacific Northwest. Intensive utilization and management can deprive these habitats of large fallen trees. The publication presents sound information for managers making resource management...

Effects of canopy gaps in Douglas-fir forests and resource gradients on fecundity and growth of understory herbs

Creator:: St. Pierre, Elizabeth A. (Elizabeth Ann)
Abstract:: Effects of small-scale disturbances on fecundity and growth rates of Linnaea borealis L., Tiarella trifoliata L. var. unifoliata, and Trillium ovatum Pursh. were studied in old-growth forests in the Tsuga heterophylla Zone on the west slope of the Cascade Mountain Range of Oregon. Performance of each species was compared in...

Potential carbon storage at the landscape scale in the Pacific Northwest, U.S.A.

Creator:: Smithwick, Erica Ann Hoffa
Abstract:: Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...

Spatial distribution of understory vegetation in tree canopy gaps of the Pacific Northwest

Creator:: London, Sharon Gail
Abstract:: Understory vegetation in artificially created tree canopy gaps in the Pacific Northwest was studied to determine 1) variation in understory vegetation cover between gap edges and gap centers, as well as between control and treatment plots, 2) spatial patterns of biomass and difference in biomass patterns among plots, 3) individual...

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

Forest canopy sturcture in western Oregon : characterization, methods for estimation, prediction, and importance to avian species

Creator:: Fiala, Anne C. S.
Abstract:: Characterization of canopy structure, the horizontal and vertical distribution of the tree crowns in a forest, is important for the management of forests in the Pacific Northwest. The canopy is an important habitat element for many wildlife species, canopy structure affects understory development, and influences various natural processes, such as...

Wind direction and effect of tree lean on coarse woody debris production

Creator:: Bustos-Letelier, Oscar
Abstract:: The natural fall of trees in riparian areas is an important source of coarse woody debris for mountain streams, improving fish habitat and influencing stream morphology. Existing models consider the probability of coarse woody debris entering a stream channel based upon trees having a random direction of fall without consideration...
