Historical disturbance regimes as a reference for forest policy

Thompson, Jonathan R. (2004-06-21)

Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is ...
History of the development, use, and management of forest resources

Walstad, John D. (Corvallis, OR: Forest Research Laboratory. Oregon State University, 1992)
Host associations of Tricholoma magnivelare, the American matsutake

Lefevre, Charles K. (2002-05-24)

Beginning in the 1980s, large-scale commercial harvest of Tricholoma magnivelare created a need for management of forests to ensure sustainability, but little was known of the biology or ecology of this species to guid ...
Host–parasite distributions under changing climate: Tsuga heterophylla and Arceuthobium tsugense in Alaska

Barrett, Tara M.; Latta, Greg; Hennon, Paul E.; Eskelson, Bianca N.I.; Temesgen, Hailemariam (NRC Research Press, 2012)

Dwarf mistletoes (Arceuthobium species) influence many processes within forested ecosystems, but few studies have examined their distribution in relation to climate. An analysis of 1549 forested plots within a 14.5 milli ...
Hot-yarding as an alternative approach to cable thinning in young forest stands : a comparative study

Lucas, Alan R. (1983-03-01)
An HP-75/HP--86 computer data collection system for recording and displaying logging equipment time studies

Campbell, Thomas M. (2009-04-23)
Human influences on historical and current wildlife distributions from Lewis & Clark to today

Laliberte, Andrea S. (2003-06-02)

Although it is well known that humans are strong modifiers of their environment, there is a need for greater understanding of human-wildlife interactions, both historically as well as currently. Historical journals can ...
Hungry Bob Harvest Production Study : mechanical thinning for fuel reduction in the Blue Mountains of northeast Oregon

Coulter, Elizabeth Dodson (1999-04-26)

Fire exclusion in the western U.S.A. has caused fuel loads to build up and overall forest health to decline. Managers are now looking for ways to reduce these fuel loads while reintroducing some of the desired effects ...
The hunted: commercially attractive truffles native to North America

Trappe, James M. (Natural Resources Canada = Ressources naturelles Canada, 2009-11)
Hybridized framing to modify load paths and enhance wood shearwall performance

Bultena, Sarah M. (2006-06-26)

Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, ...
Hydraulic performance of countersunk culverts in Oregon

White, Dale (Dale Jeffery), 1963- (1996-11-26)

Twenty eight countersunk culverts in Oregon were evaluated to assess current conditions and hydraulic performance. The culverts were also assessed with respect to their stability, particularly when subjected to high flow ...
Hydraulic properties of compression wood in branches and reoriented shoots of Douglas-fir (Psuedotsuga menziesii)

Spicer, Rachel (1997-07-02)

Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xyle ...
Hydraulic safety margins and embolism reversal in stems and leaves: Why are conifers and angiosperms so different?

Johnson, Daniel M.; McCulloh, Katherine A.; Woodruff, David R.; Meinzer, Frederick C. (Elsevier, 2012-10)

Angiosperm and coniferous tree species utilize a continuum of hydraulic strategies. Hydraulic safety margins (defined as differences between naturally occurring xylem pressures and pressures that would cause hydraulic dy ...
Hydro-biogeochemical coupling at the hillslope and catchment scale

van Verseveld, W.J. (Willem J.) (2007-10-01)

The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls ...
Hydrologic factors and environmental impacts of mass soil movements in the Oregon Coast Range

Ketcheson, Gary Leslie (1977-12-09)

Mass soil movements of four types; debris avalanche, debris torrent, debris slide and bank slough, were field inventoried in the Oregon Coast Range. A total of 104 mass movements were located in 21 undisturbed watersheds ...
Hydrologic properties of soil and subsoil on a steep, forested slope

Ranken, Darrel Wesley (1974-03-22)

The purpose of this study was to examine certain hydrologic properties of the soil and subsoil on a steep forested slope and relate these -rceTties to the movement of water via subsurface routes. The hydrologic proper ...
Hydrology of five forest roads in the Oregon Coast Range

Marbet, Christine Erica (2003-07-18)

Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in t ...
The hydrology of the humid tropics

Wohl, Ellen; Barros, Ana; Brunsell, Nathaniel; Chappell, Nick A.; Coe, Michael; Giambelluca, Thomas; Goldsmith, Steven; Harmon, Russell; Hendrickx, Jan M. H.; Juvik, James; McDonnell, Jeffrey; Ogden, Fred (Nature Publishing Group, 2012-09)

Hydrological processes in the humid tropics differ from other regions in having greater energy inputs and faster rates of change, including human-induced change. Human influences on population growth, land use and climat ...
Hygro-mechanical response of clear softwood specimens to compression under cyclic climate

Guo, Ning (2009-09-21)

Hygro-mechanical effect is a general term applied to all phenomena that involves interaction between moisture content and mechanical characteristics of hygroscopic materials by analogy to thermo-mechanical effects. The h ...
Identification of variables influencing residual stand damage from skyline thinning of young western hemlock-Sitka spruce stand

Hargrave, Michael A. (2009-04-23)

Western hemlock and Sitka spruce are relatively thin- barked species and susceptible to damage during thinning operations. Damage to the wood allows decay-causing fungi to enter resulting in loss of merchantable volum ...
