Recovering lost ground: Effects of soil burn intensity on nutrients and ectomycorrhiza communities of ponderosa pine seedlings

Creator:

Cowan, Ariel D., Smith, Jane E., and Fitzgerald, Stephen A.

Abstract:

Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in pon-derosa pine (Pinus ponderosa) forests of central Oregon. The combustion of fuels containing large downedwood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previousstudies show ectomycorrhizal fungi (EMF) improve...

Evaluating Multi-objective Trade-offs in Mature Douglas-fir (Pseudotsuga menziesii) Stands of Western Oregon

Creator:

Williams, Neil G.

Abstract:

Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...

The Effects of Seed Source and Planting Environment on Douglas-fir (Pseudotsuga menziesii) Foliage Diseases

Creator:

Wilhelmi, Nicholas

Abstract:

Douglas-fir (Pseudotsuga menziesii) is a commercially and ecologically important tree species native to western North America. The foliar pathogens Phaeocryptopus gaeumannii, the causal agent of Swiss Needle Cast, and Rhabdocline species, the causal agents of Rhabdocline needle cast, are two important pathogens specific to Douglas-fir. These pathogens are highly influenced...
