Creator:: Fiorella, Maria R.
Abstract:: 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...

Creator:: Kushla, John D.
Abstract:: This investigation on fire mosaics addressed several aspects: (1) quantifying the role of terrain variables in fire-related mortality and historical mean fire return interval (MFRI), (2) comparing post-burn Landsat Thematic Mapper (TM) imagery, TM difference imagery, and aerial photo interpretation to map forest survival after wildfire, and (3) to describe...

Creator:: Bradshaw, G. A.
Abstract:: There has been an increased interest in the quantification of pattern in ecological systems over the past years. This interest is motivated by the desire to construct valid models which extend across many scales. Spatial methods must quantify pattern, discriminate types of pattern, and relate hierarchical phenomena across scales. Wavelet...

Creator:: Swindle, Keith A.
Abstract:: This study describes the composition of forest landscapes surrounding northern spotted owl (Strix occidentalis caurina) nests in the central Cascade Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair territories with forest composition around 119 points drawn randomly from all terrestrial cover-types, and around 104...

Creator:: Rasmussen, Mary C.
Abstract:: Using historical maps and tools provided by GJS, the spatial patterns of pre-logging forest conditions were quantified for three landscapes in western Oregon. The spatial coincidence between forest patches and topographic features was determined for slope gradient, aspect, elevation, and distance from streams. Pre-logging and current forest compositions were compared....
