Research Data Sets

North American Porcupines (Erethizon dorsatum) have a broad geographic distribution across much of the continent, but recent evidence suggests that their populations may be declining in some areas, including the Pacific Northwest. Estimating baseline historical and contemporary distributions of Porcupines is necessary for initiating monitoring efforts and, if necessary, informing strategic conservation actions. We compiled 1905 occurrence records of Porcupines in Washington, Oregon, and northern California from 1908 to 2018. Using maximum entropy modeling (Maxent), we created historical and contemporary distribution models based on Porcupine records from 1981–2010 and 2012–2018, respectively, to match the temporal scale of available …

Spatial Aspects Of Tree Mortality Strongly Differ Between Young And Old-Growth Forests, Andrew J. Larson, James A. Lutz, Daniel C. Donato, James A. Freund, Mark E. Swanson, Janneke Hillrislambers, Douglas G. Sprugel, Jerry F. Franklin

Forest Management Faculty Publications

Rates and spatial patterns of tree mortality are predicted to change during forest structural development. In young forests, mortality should be primarily density dependent due to competition for light, leading to an increasingly spatially uniform pattern of surviving trees. In contrast, mortality in old-growth forests should be primarily caused by contagious and spatially auto-correlated agents (e.g., insects, wind), causing spatial aggregation of surviving trees to increase through time. We tested these predictions by contrasting a three-decade record of tree mortality from replicated mapped permanent plots located in young (<60-year-old) and old-growth (>300-year-old) Abies amabilis forests. Trees in young forests died at a …

Who Governs the Public Lands: Washington? The West? The Community? (September 28-30)

Conference organizers and/or session moderators included University of Colorado School of Law professors David H. Getches, Judith Jacobsen, Lawrence J. MacDonnell, Teresa Rice and Charles F. Wilkinson.

Shifting policy objectives and management approaches for the public lands of the West are provoking heated debate about how these decisions should be made and implemented. Are these policy directions a reflection of the "New West" or are they, in fact, a declaration of "war on the West"? Somewhere between these polarities of view, efforts are underway to open dialogue and reach consensus.

This second annual western lands conference will explore federal initiatives …

Water Quality Control: Integrating Beneficial Use and Environmental Protection (Summer Conference, June 1-3)

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.

Protecting water quality is essential to preserve the many beneficial uses of western water resources. This conference addresses the dominant federal requirements in the Clean Water Act, including the important major revisions enacted by Congress in 1987, with special attention to western problems regarding nonpoint source pollution. Developments in groundwater quality regulation are considered, as are selected issues concerning the implications of state and federal water quality regulation for the traditional exercise of water rights.

A Study Of The Vegetation Of Southeastern Washington And Adjacent Idaho, J. E. Weaver

Papers from the University Studies series (University of Nebraska)

Noone at all botanically inclined can travel through southeastern Washington without being impressed with the marked changes which a distance of only a few miles may show in the vegetation. Traveling eastward from a point fifty miles west of the Idaho state line, one passes from a region of scab-land sagebrush through one of rolling hills covered with bunch-grasses. Upon steadily ascending the great Columbia Plateau, the 'bunchgrasses give way to well developed prairies, and these in turn, near the Idaho line, to forests of yellow pine, Douglas fir, white fir, tamarack, and cedar. Or starting from Spokane in the …
