Habitat use by cavity-nesting birds in young thinned and unthinned Douglas-fir forests of western Oregon

Creator:

Weikel, Jennifer M.

Abstract:

There is limited information on how to manage young forests of the Pacific Northwest to benefit wildlife populations. Commercial thinning is becoming more important in young forests both as a tool for timber management and to hasten the development of old-forest characteristics. There is some evidence that many species of...

Thinning response in Alnus rubra and Arbutus menziesii : effects of spacing, light, and moisture

Creator:

Kim, Sang-kyun

Abstract:

In western Oregon, hardwood trees occupy 20% of the timberland but account for less than 1% of the timber harvest. Information about how to manage them effectively is limited. The objective of this study was to examine: 1) effect of thinning on tree growth, plant moisture stress, and crown cover...

The structure and development pattern of mixed-species forest stands in the interior cedar-hemlock zone : moist cold subzone of northwestern British Columbia

Creator:

LePage, P. (Philip)

Abstract:

A field study was established to explore stand structure and development patterns of mature, mixed-species forests in the Interior Cedar-Hemlock (ICH) zone: moist cold subzone of northwestern British Columbia. The species of interest in the study area were: western hemlock (Tsuga heterophylla (Raf.) Sarg.), western redcedar (Thuja plicata Donn), lodgepole...

Water relations, survival and growth of Douglas-fir seedlings at a pinegrass dominated site in the interior Douglas-fir zone of south-central British Columbia

Creator:

Nicholson, Alison Campbell

Abstract:

A field study was conducted to determine the impact of microclimate and vegetation on survival and growth of planted Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) at a pinegrass (Calamagrostis rubescens Bucki.) dominated clearcut in the Interior Douglas-fir Zone of south-central British Columbia. The study focussed on (1) the water balance of...

Masters Thesis
A stand management strategy for young western hemlock-Sitka spruce forests

Creator:

Kellogg, L. D. (Loren D.)

Abstract:

Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive young-growth management types along the Pacific Coast from Oregon to southeast Alaska. These stands are ready for a first commercial thinning entry, however, the costs and benefits of such entries and resulting impacts at...

Dissertation
Interacting effects of stand density, site factors, and nutrients on productivity and productive efficiency of Douglas-fir plantations in the Oregon Cascades

Creator:

Velazquez-Martinez, Alejandro

Abstract:

The objectives of this research were to study: a) the effect of thinning and treatments consisting of pruning and multinutrient fertilization on aboveground biolnass increment, growth efficiency (GE), and foliar nutrients; b) the influence of topoedaphic variables (soil nutrients, slope, aspect, and rock content) and foliar nutrients on both leaf...

Dissertation
Characteristics and spatial relationships of day-roosts and activity areas of female long-eared myotis (Myotis evotis) in western Oregon

Creator:

Waldien, David L.

Abstract:

Management of habitat for bats requires sound information on their habitat requirements. I used radio telemetry to identify 80 roosts for 24 long-eared myotis (Myotis evotis); 74 roosts were identified for 21 females and 6 roosts for 3 males. Females primarily used dead and defective conifer trees (n=22) and conifer...
