Effects of timber harvest and forest edges on abundance, viability, and physiology of understory plants in Pseudotsuga forests of western Washington
There is widespread interest in the ecological effects of timber harvest, the resultant fragmentation of forest habitat, and the increased area of forest edges. However, there has been surprisingly little research devoted to the consequences of these management activities for understory plants. I investigated short-term ...
Mycorrhizal fungus communities of Douglas-fir (Pseudotsuga menziesii) seedlings and trees: effects of proximity to residual trees
The influence of mature Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees in partially harvested stands on seedling growth and colonization by ectomycorrhizal fungi (EMF) is not well understood. To investigate this, Douglas-fir seedlings were planted near (<6 m) and far (>16 m) from 44- to 72-year-old residual Douglas-fir ...
