Placement of felled western juniper trees over a stream channel : Effects on water temperature, streamside willow shrubs, and redband trout

Creator:: Matney, Casey A.
Abstract:: All streams in Oregon that are inhabited by salmon and trout have a statemandated water temperature standard. However, temperatures of many streams, especially during summer months, exceed the seven-day average maximum temperature parameter (200 C for redband trout inhabited streams) accepted by the Oregon Department of Environmental Quality. To date,...

Recruitment and abundance of large woody debris in an Oregon coastal stream system

Creator:: Long, Barry A.
Abstract:: Research was conducted in the Oregon Coast Range to address the concern that conversion of large diameter old-growth forests to small diameter second-growth forests would lead to reduction of large woody debris in adjacent stream channels. The objective of the study was to quantify spatial trends in large woody debris...

The imprint of coarse woody debris on soil biological and chemical properties in the western Oregon Cascades

Creator:: Spears, Julie D. H.
Abstract:: The abundance and spatial heterogeneity of coarse woody debris (CWD) on the forest floor is a prominent feature of Pacific Northwest (PNW) forest ecosystems. The effect of CWD on soil solution chemistry, nutrient cycling and availability, soil physical structure and formation of soil organic matter, however, remains unknown. Therefore, studies...

The effect of the size and orientation of large wood on pool volume in two Oregon Coast Range streams

Creator:: Lombard, Pamela
Abstract:: This study was conducted to determine how the size and orientation of large wood placed in streams in combination with peak flows, substrate and channel gradient affect pool volume, surface area and maximum depth in two coastal Oregon streams. Eighteen Douglas-fir (Pseudotsuga menziesii) logs were placed in each of two...

Forest harvesting impacts on coarse woody debris and channel form in central Oregon streams

Creator:: Knight, Stephen M.
Abstract:: Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

Dead wood dynamics and relationships to biophysical factors, forest history, ownership, and management practices in the Coastal Province of Oregon, USA

Creator:: Kennedy, Rebecca S.H.
Abstract:: Dead wood patterns and dynamics vary with biophysical factors, disturbance history, ownership, and management practices. Through field and modeling studies, I examined the current and potential future amounts of dead wood in two landscapes and region-wide in the Coastal Province of Oregon. The objectives of the first study were to...

Recruitment trends and physical characteristics of course woody debris in Oregon Coast Range streams

Creator:: Heimann, David C.
Abstract:: This study investigated the long-term consequences of timber stand removal on the recruitment, physical characteristics, and spatial distribution of coarse woody debris in small (second- and third-order) streams of the Oregon Coast Range. A chronosequence of stream-stand systems, ranging from 21- to 140-years since disturbance (YSD), were sampled to determine...

Breeding site selection by coho salmon (Oncorhynchus kisutch) in relation to large wood additions and factors that drive reproductive success

Creator:: Clark, Steven
Abstract:: The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. Accordingly, breeding sites should...

Incorporation of salmon derived nutrients into Oregon coastal streams and the role of physical habitat

Creator:: Shaff, Courtney D.
Abstract:: Stream restoration techniques in western Oregon and Washington include physical habitat restoration and more recently the addition of salmon carcasses to improve food availability for juvenile fish. Although both are common practices, few studies have examined the effects of carcass placement and the interaction of nutrient enrichment with physical habitat...

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...
