Prediction of the biomass, leaf area, and crown area of sprout clumps of tanoak (Lithocarpus densiflorus (Hook. and Arn.) Rehd.) : a technique for assessing site occupancy by this species

Creator:: Harrington, Timothy B. (Timothy Brian)
Abstract:: Tanoak (Lithocarpus densflorus (Hook and Am.) Rehd.), an evergreen hardwood tree that grows abundantly in southwest Oregon and north California, sprouts vigorously after a disturbance, such as logging or fire These sprouts form clumps that can hamper conifer regeneration on clearcuts and in shelterwoods. In order to obtain a quantitative...

Tanoak (Lithocarpus densiflorus (Hook & Arn.) Rehd.) root dieback : below- and aboveground site occupancy by stump-sprouts in southwest Oregon

Creator:: Ahrens, Glenn R.
Abstract:: Residual roots from previous stand components are often cited as a major benefit to stump-sprouts of tanoak in southwest Oregon and northern California. Established patterns of belowground carbon allocation and root/shoot maintenance suggest that residual root systems of stumps will be reduced by carbohydrate depletion and root mortality and by...

Trends in riparian vegetation regrowth following timber harvesting in western Oregon watersheds

Creator:: Summers, Richard P.
Abstract:: This study investigated the development of riparian zone vegetation at varying stand ages from one to 29 years following clearcut timber harvesting in western Oregon. Vegetation was classified into three layers for observation including the ground (less than 13 cm), the understory (less than 2.5 m), and the overstory (greater...

Soil moisture depletion trends under five plant species present on the Douglas-fir clear-cuts of Mary's Peak, Oregon

Creator:: Drew, Stephen Ernest
Abstract:: Soil moisture depletion trends under five plant species growing on the clear-cuts of the Marys Peak Watershed near Corvallis, Oregon, were followed during the summers of 1963 and 1964. The species were Holcus lanatus, Lotus crassifolius var. subglaber, Gaultheria shallon, Berberis nervosa, and Acer circinatum; and were dominant plants of...

Growth and replacement patterns occuring among selected dominant species associated with plant succession on Douglas fir clear-cuts

Creator:: Robinson, Myles Canby
Abstract:: Growth and replacement patterns of four successionally important species occurring on Douglas fir clear-cuts were investigated from September 1964 to June 1967. The study was carried out on the Marys Peak watershed located near Corvallis, Oregon. Species used in the study include Holcus lanatus, Senecio jacobaea, Lotus crassifolius var. subglaber,...

Soil and understory vegetation characteristics of a tractor-logged forest in eastern Oregon

Creator:: Snider, Michael Duane
Abstract:: A 1.5 ha mixed conifer stand in the Blue Mountains of Oregon was intensively examined to assess the impact of logging disturbance on soils and herbaceous vegetation. Sampling was conducted six years after much of the timber overstory was removed in a shelterwood cut and yarded by crawler tractor. A...

Effects of clearcutting a Douglas-fir stand upon small animal populations in western Oregon

Creator:: Hooven, Edward F. (Edward Frank)
Abstract:: An ecological study of small forest mammals was conducted from 1964 to 1970. The objectives were to obtain chronological information relative to the effects of current logging practices on vegetational succession and small mammal populations. The locale of the study was in the west-central Cascade Mountains of Oregon. The principal...

Energy exchange of transplanted Douglas-fir seedlings on two cutover sites in southwestern Oregon

Creator:: Vanderwaal, James A.
Abstract:: An energy balance analysis was performed on each of four transplanted Douglas-fir [Pseudotsuga menziesii (Mirb.) Francol seedlings growing on two cutover sites in southwestern Oregon. The two sites were a clearcut and a partial-cut (shelterwood) side by side, with a pair of seedlings used on each site. One seedling of...

Regeneration patterns on some modified staggered-setting clearcuts on the H.J. Andrews experimental forest

Creator:: Franklin, Jerry F.
Abstract:: A survey of natural regeneration of Doug1as-fir and associated species was made on 15 staggered-setting cuttings four and five years after logging. These areas were on the H. J. Andrews Experimental Forest which is located in the McKenzie River area of western Oregon. Five types of cuttings were represented: (1)...

Early forest succession following clearcuts in western Oregon : patterns and abiotic controls

Creator:: Yang, Zhiqiang
Abstract:: Historical aerial photos were used to examine the early phase of forest succession after stand replacement disturbance, covering the Coast Ranges Province (CRP) and the western Cascades Province (WCP) of western Oregon. The study consisted of two components: characterizing the pattern of forest succession in western Oregon; analyzing the influence...
