Forest Canopy Heights in the Pacific Northwest Based on InSAR Phase Discontinuities across Short Spatial Scales

Rapid land use changes are substantially altering the global carbon budget, yet quantifying the impact of these changes, or assessing efforts to mitigate them, remains challenging. Methods for assessing forest carbon range from precise ground surveys to remote-sensing approaches that provide proxies for canopy height and structure. We introduce a method for extracting a proxy for canopy heights...

Forest Fragmentation in the Pacific Northwest and its Potential Effects on Wildlife

Fragmentation is the creation of a complex mosaic of spatial and successional habitats from formerly contiguous habitat. Loss of habitat and the less obvious phenomenon of habitatpatch isolation are aspects ‘of fragmentation that threaten the viability of wildlife populations, the components of biotic diversity. Fragmentation of forests on Federal lands in the Pacific Northwest is the product o...

Starlings in the Pacific Northwest

Toward Geodesign for Watershed Restoration on the Fremont-Winema National Forest, Pacific Northwest, USA

Spatial decision support systems for forest management have steadily evolved over the past 20+ years in order to better address the complexities of contemporary forest management issues such as the sustainability and resilience of ecosystems on forested landscapes. In this paper, we describe and illustrate new features of the Ecosystem Management Decision Support (EMDS) system that extend the s...
