Overview This project examines the ecological impacts of several introduced and expanding forest insects and diseases on forest habitats across the northeastern US and upper Lake States region. To address these novel threats, this work applies large-scale, co-developed experimental studies documenting impacts of ash mortality from emerald ash borer on lowland black ash communities in the Lake States and northern hardwood forests in New England; regional assessments of the impacts of the climate change-mediated expansion of southern pine beetle into northeastern pine barren communities; and ecological characterizations of areas experiencing suppression efforts to reduce the spread of the introduced Asian long-horned...

Black ash wetlands occupy over 1.2 million hectares of forest in the Great Lakes region, providing habitat for unique and diverse wildlife communities. In these wetlands, black ash trees are a foundational species, regulating all aspects of ecosystem function, and are also an important cultural resource for Native Americans, specifically for basket-makers. Black ash wetlands are critically threatened by the interaction of climate change and the invasive emerald ash borer (EAB), which is expected to spread northward and westward into large expanses of black ash with warming winters. These threats present a significant challenge for long-term conservation efforts to preserve ecosystem functions, cultural lifeways,...

Forests across the U.S. are experiencing unprecedented tree mortality caused by a variety of stressors, including invasive insects, disease, extreme weather, wildfires, and droughts. For example, the emerald ash borer, a nonnative insect, has killed tens of millions of trees in the Lake States region of Minnesota, Wisconsin, and Michigan alone in the past decade. Tree die offs alter the structure of forests, making them less-suitable habitat for many species, and decrease their ability to perform important ecosystem functions, such as carbon sequestration. Climate change further threatens already damaged forests, as shifting temperature and precipitation conditions alter species’ range limits. To prevent additional...

Overview This project is using a combination of long-term data records and recently established large-scale adaptive management studies in managed forests across the Lake States, New England, Intermountain West, and Black Hills to identify forest management strategies and forest conditions that confer the greatest levels of resistance and resilience to past and emerging stressors and their relevance in addressing future global change. This work represents a broad partnership between scientists from the USFS Northern Research Station, USFS Rocky Mountain Research Station, USGS, University of MN, University of Maine, and Dartmouth College in an effort to capitalize on over 50 years of data collection on USFS...
