The purpose of this study was to better understand the level of
wetland classification consistency among three different land cover layers
created using Geographical Information System (GIS) and remote sensor
technology. Where inconsistencies in data existed, the goal was to identify the
kinds of inconsistencies that occur. The results were...
Several state and federal agencies have identified Oregon's coastal wetlands as
priority areas for conservation, and in some cases have specifically singled out
nontidal (mostly palustrine) wetlands as a major concern. Recent research has
highlighted the need to study and manage wetlands from a regional perspective that
considers the distribution...
Increasing population and land use decisions have had a negative effect on the aquatic ecosystems in the Willamette River Basin. One result is elevated temperatures in many of the Basin’s streams, which adversely affect the fish that live in these streams. There are several regulatory mechanisms in place to improve...
This study was conducted to explore differences in diversity and abundance of small
mammal populations in natural and restored wet prairies in Oregon's Willamette Valley.
Mammals were live-trapped in eight Willamette Valley wet prairies (four natural remnants and
four restorations) during the summer of 2000; population abundance estimates for each...
Invasion by exotic species can pose a major challenge for developing native
plant communities in wetland restoration projects. Often native plant communities
do not develop as anticipated in restored wetlands due to colonization by exotic
species that dominate the native plant community. Despite the time and expense to
restore wetlands,...
