Creator:: Rice, Janine M.
Abstract:: Montane meadows comprise a small area of the predominantly forested landscape of the Oregon Cascade Range. Tree encroachment in the last century in these areas has threatened a loss of biodiversity and habitat. Climate change in the coming century may accelerate tree encroachment into meadows, and exacerbate biodiversity loss. Multiple...

Full Text:: presented on December 11, 2009. Title: Forest-Meadow Dynamics in the Central Western Oregon Cascades

Creator:: Moore, Georgianne W.
Abstract:: I compared transpiration among different types of forest stands in the western Cascades of Oregon. The three major questions were: 1) How does transpiration compare between a young and old stand and why? 2) Does diversity of overstory trees affect transpiration? and 3) How is transpiration related to stream flow?...

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Full Text:: Characterization of Douglas-fir/Western Hemlock Forests in the Central Western Cascades of Oregon Abstract

Creator:: Watterson, Nicholas
Abstract:: This project explores mechanisms governing the invasion of fluvial systems by two contrasting exotic species in stream networks of steep, relatively remote forested landscapes of western Oregon. This research addresses hypotheses relating limitations of seed source locations, seed transport processes, and sink availability to the distributions of scotch broom (Cytisus...

Creator:: Czarnomski, Nicole M.
Abstract:: Despite many studies of large wood in streams, few landscape scale studies have been conducted. Large-scale studies can reveal how the history of forest harvest and road building has influenced wood patterns in streams of the Pacific Northwest. This study examined the relationships between wood in streams, timber harvest, and...

Full Text:: Harvest and Roads on In-stream Wood Abundance in the Blue River Basin, Western Cascades, Oregon

Creator:: Highland, Steven A.
Abstract:: Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...
