Influence
of Landscape Pattern and Composition
on Species in Forested Ecosystems of Western Oregon
Understanding the effects
of management at landscape scales is critical to managing for
habitat and biodiversity. However,
knowledge of the influence of landscape effects on many species
is lacking. There is growing consensus that knowledge of the
form, function, and historical context of landscapes is essential
to research and management of ecosystems at a variety of temporal
and spatial scales.
Goal
The
goal of this project is to investigate the relationships
among aquatic and terrestrial organisms, instream
habitat, and riparian-area and upslope conditions
across broad geographic areas in western Oregon.
Objectives
Several
questions are critical for an understanding of the
consequences of habitat alteration in forested biomes
of western Oregon.
•
Objective
1: Explore how instream habitat and watershed
characteristics (including riparian-area and upslope
conditions) affect distribution and abundance of
potamodromous and nonmigratory fishes across broad
geographic areas in western Oregon.
•
Objective
2: Determine what stream, stand, and basin-scale
characteristics are important in determining the
occurrence and distribution of amphibians found
in headwater streams of western Oregon.
•
Objective
3: Determine the influence of landscape characteristics
on abundance and habitat use of bats of western
Oregon.
However,
knowledge of the influence of landscape effects on many species
is lacking. There is growing consensus that knowledge of the
form, function, and historical context of landscapes is essential
to research and management of ecosystems at a variety of temporal
and spatial scales.
