Forest collaboration emerged in Oregon about 30 years ago as a way to address increasing conflict and distrust amongst stakeholder groups and public land managers. The concept has spread widely, and forest collaboratives are now commonplace on most National Forests in the Pacific Northwest. These groups include a wide range...
Two distinct nocturnal subcanopy flow regimes are observed beneath a tall (16 m) open pine forest canopy. The first is characterized by weaker mixing, stronger stability, westerly downslope flow decoupled from the flow above the canopy and much smaller than expected ecosystem respiration from the eddy flux plus storage measurements...

Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...
The trails included in this book will lead you to mountain-top vistas, lakes, waterfalls and old-growth forests, towering secondgrowth forests, rocky bluffs and alpine meadows. We've included a variety of trails:
• short walks for those seeking fresh air and a place to stretch their legs
• medium length trails...
Grazing cattle usually have access to streams as a
source of drinking water. A model was developed for the
personal computer to predict the bacterial quality of
these streams. The model estimates the number of
organisms that enter the stream by the direct deposit of
feces and by runoff from...

Variable area surveys are used in large geographic regions to estimate the density of birds distributed over a region. If some birds go undetected, a measure of the effective area surveyed, the amount of area occupied by the birds detected, is needed. The effective area surveyed is determined by observational,...
