Concern over global environmental change and associated uncertainty has given rise to greater emphasis on fostering resilience through forest management. We examined the impact of standard silvicultural systems (including clearcutting, shelterwood, and selection) compared with unharvested controls on tree functional identity and functional diversity in three forest types distributed across the northeastern United States. Sites included the Argonne, Bartlett, and Penobscot Experimental Forests located in Wisconsin, New Hampshire, and Maine, respectively. We quantified functional trait means for leaf mass per area, specific gravity, maximum height, height achieved at 20 years, seed mass, drought tolerance, shade tolerance,...

Society makes substantial investments in federal, Tribal, state, and private programs to supplement populations of valued species such as stocking fish, planting trees, rebuilding oyster reefs, and restoring prairies. These important efforts require long-term commitment, but climate change is making environmental conditions less predictable and more challenging to navigate. Selection of species for population supplementation is often based on performance prior to release, and one or a few species may then be used for decades even as the environment is changing. When these species are propagated in large numbers, they can become the dominant population as well as genetically overtake any local adaptations. Therefore,...

Eastern spruce-fir forest ecosystems are among the most vulnerable to climate change within the conterminous US. The goal of this project was to develop tools to identify refugia sites most likely to support spruce-fir forest and its associated high-priority obligate spruce-fir bird species over the long-term under projected climate change scenarios. Specific research objectives included: (1) producing high-resolution (temporal and spatial) projections of spruce-fir forests, including stand characteristics like structure and composition; (2) estimating future changes in the distribution, productivity, and stand characteristics of the spruce-fir forest type due to potential changes in climate; (3) comparing the distribution...

Black ash (Fraxinus nigra) forests, which cover over 1.2 million hectares in the Great Lakes Region, are threatened by emerald ash borer (EAB; Agrilus planipennis), which is eliminating native populations of ash throughout the region. Understanding the contribution of black ash wetlands to local and regional species richness is critical in forming effective conservation policies and informing management plans for these imperiled habitats. We measured breeding bird and anuran communities in black ash wetlands and compared them to nearby non-black ash habitats for each taxa: aspen-dominated upland forest for birds and emergent wetlands for anurans. Our results showed black ash wetlands support unique communities of...
