The adoption of ecosystem-based management strategies focuses attention on the need for broad scale estimates of ecological conditions; this poses two challenges for the science community: estimating broad scale ecosystem conditions from highly disparate data, often observed at different spatial…

Northern flying squirrels (Glaucomys sabrinus) in the USA Pacific Northwest are keystone species that disseminate the spores of ectomycorrhizal fungi symbiotic with Pinaceae and that are preyed upon by a variety of vertebrate predators. Substantial research has shown that these squirrels…

Two strategies for managing forests for multiple values have achieved prominence in debates in the Pacific Northwest: (1) legacy retention with passive management and long rotations, and (2) intensive management for timber with commercial thinnings and long rotations. Northern flying squirrels (…

Public lands in the US Rocky Mountains provide critical ecosystem services, especially to rural communities that rely on these lands for fuel, food, water, and recreation. Climate change will likely affect the ability of these lands to provide ecosystem services. We describe 2 efforts to assess…

Principles for sustainable-ecosystem management are derived by integrating fundamental, societal, and scientific premises. Ecosystem science is applied in the design of a system of management focused on building overlap between what people collectively want and what is ecologically possible. We…

Decision making for forest ecosystem management can include the use of a wide variety of modeling tools. These tools include vegetation growth models, wildlife models, silvicultural models, GIS, and visualization tools. NED-2 is a robust, intelligent, goal-driven decision support system that…

The paper presents an approach for delimiting communities in the Northwest Forest Plan (NWFP) region of the Pacific Northwest that responds to the need to assess impacts and issues associated with broad-scale ecosystem management. Census block groups are aggregated to provide an alternative to more…

Trends of mean annual increment and periodic annual increment were examined in 17 long-term thinning studies in coast Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) in western Washington, western Oregon, and British Columbia. Maximum ages included ranged from about 90…
