Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...
Airborne discrete-return lidar is an active remote sensing technology capable of obtaining accurate, fine-resolution three-dimensional measurements over large areas. Discrete-return lidar data produce three-dimensional object characterizations in the form of point clouds defined by precise x, y and z coordinates. The data also provide intensity values for each point that...

The vegetation of a 420 square mile area of the
Oregon Coastal Mountain Range was mapped using data from
the multispectral scanner system aboard Landsat.
Advantages of this mapping system include rapid synoptic
coverage of the same geographic area at different
periods in time at a reduced cost compared to...
Fire regimes across the western United States have been altered due to past land management and changing land use. Mitigating increased risks of wildfire occurrence in landscapes such as central Oregon requires landscape level management from both governmental and private organizations. Non-industrial private forest (NIPF) owners manage a relatively small...
A per-segment classification system was developed to map aspen (Populus tremuloides) stands on Winter Ridge in central Oregon from remote sensing imagery. A 1-meter color infrared (CIR) image was segmented based on its hue and saturation values to generate aspen "candidates", which were then classified to show aspen coverage according...
Forest and wildlife habitat analyses were conducted
at the H.J. Andrews Experimental Forest in the Central
Cascade Mountains of Oregon using remotely sensed data and
a geographic information system (GIS). Landsat Thematic
Mapper(TM) data were used to determine forest successional
stages, and to analyze the structure of both old and...
