The combined effects of vegetation control and seedling size class on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedling productivity on a site in Oregon

Creator:

Lefebvre, Robert F.

Abstract:

Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:

Dinger, Eric J.

Abstract:

Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...
