Understanding how climate change may influence forest carbon (C) budgets requires knowledge of forest growth relationships with regional climate, long-term forest succession, and past and future disturbances, such as wildfires and timber harvesting events. We used a landscape-scale model of forest succession, wildfire, and C dynamics (LANDIS-II) to evaluate the effects of a changing climate (A2 and B1 IPCC emissions; Geophysical Fluid Dynamics Laboratory General Circulation Models) on total forest C, tree species composition, and wildfire dynamics in the Lake Tahoe Basin, California, and Nevada. The independent effects of temperature and precipitation were assessed within and among climate models. Results …

In this review, we summarize the potential impacts of climate change on wildfire activity in the mid-Atlantic region, and then consider how the beneficial uses of prescribed fire could conflict with mitigation needs for climate change, focusing on patters of carbon (C) sequestration by forests in the region. We use a synthesis of field studies, eddy flux tower measurements, and simulation studies to evaluate how the use of prescibed fire affects short-and long-term forest C dynamics. Climate change may create weather conditions more conducive to wildfire activity, but successional changes in forest composition, altered gap dynamics, reduced understory and forest …

In January of 2013, the Campus Sustainability Office (CSO) of Portland State University (PSU) contacted Community Environmental Services (CES) with the request to conduct a landfill-bound waste assessment for the University’s 50-acre downtown campus, located in Portland, Oregon. CES is a research and service unit within the Center for Urban Studies at Portland State University. PSU is a state university that was founded in 1946, is home to Oregon’s largest undergraduate and graduate enrollment, and is the only public university in the state located in a major metropolitan city. Portland State is world-renowned for its sustainability initiatives, and has had …

In 2010, Portland State University (PSU) adopted the University’s first Climate Action Plan (CAP) as part of the American College and University President’s Climate Commitment (ACUPCC). The CAP calls for climate neutrality by 2040 and identifies emission reduction targets in the following areas: Buildings & Energy, Materials, Travel, Commuting, Education & Research, and EcoDistrict Development. This report serves as an assessment of progress to date and provides: an updated carbon emissions profile, a snapshot of progress on individual actions, a summary of efforts contributing to CAP goals, and suggestions regarding next steps.
