Prairies were once widespread across North America, but are now one of the most endangered and least protected ecosystems in the world. Agriculture and residential development have reduced once extensive prairies into a patchwork of remnant prairies and “surrogate” grasslands (e.g., hayfields, planted pastures). Grassland ecosystems and many grassland-dependent birds are also particularly vulnerable to rapid shifts in climate and associated changes in drought and extreme weather. The Central Flyway is a vast bird migration route that comprises more than half of the continental U.S., and extends from Central America to Canada, and harbors the greatest diversity of grassland birds in North America. Throughout this...

The fast pace of change in coastal zones, the trillions of dollars of investment in human communities in coastal areas, and the myriad of ecosystem services natural coastal environments provide makes managing climate-related risks along coasts a massive challenge for all of the U.S. coastal states and territories. Answering questions about both the costs and the benefits of alternative adaptation strategies in the near term is critical to taxpayers, decision-makers, and to the biodiversity of the planet. There is significant public and private interest in using ecosystem based adaptation approaches to conserve critical significant ecosystems in coastal watersheds, estuaries and intertidal zones and to protect man-made...
Abstract (from ScienceDirect): Climate change poses threats to forests, creating a need for adaptation to novel and changing conditions. This need has led to the creation of adaptation frameworks including the resistance, resilience, transition (RRT) framework, which proposes management strategies along a gradient of change and adaptation. Although management within this framework is grounded in theory and past management experience, little is known about how these approaches may influence regeneration, a critical phase in forest development. To address this gap, we examined five-year outcomes of treatments implemented using the RRT framework as part of the Adaptive Silviculture for Climate Change network in northern...

The forests of the Northeastern United States are home to some of the greatest diversity of nesting songbirds in the country. Climate change, shifts in natural disturbance regimes, and invasive species pose threats to forest habitats and bird species in the northeastern United States and represent major challenges to natural resource managers. Although broad adaptation approaches have been suggested for sustaining forested habitats under global change, it is unclear how effective the implementation of these strategies at local and regional scales will be for maintaining habitat conditions for a broad suite of forest-dependent bird species over time. Moreover, given the diversity in forest stakeholders across the...

Coastal National Wildlife Refuges (NWRs) provide a myriad of beneficial services, including buffering storm surge, improving water quality, supporting commercial fisheries, and providing habitat for imperiled wildlife and plants. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the goods and services provided by NWRs and pose decision-making challenges for refuge managers. The purpose of this project was to explore how structured decision-making – a formal, systematic method for analyzing decisions – could help NWR staff make informed...

This project compiled, synthesized, and communicated tailored climate change information to NE CASC stakeholders, including Landscape Conservation Cooperatives (LCC), state and federal agencies, and tribal communities. Our mission is to make climate science actionable by getting to know our stakeholders and the decisions they face, and delivering climate information that is directly relevant to their decisions and priorities. The project team served as a resource to answer individual inquiries related to climate model projections in order to aid climate change adaptation. Additionally, the team contributed to the development of a synthesis document to help the Midwest and Northeast states prepare their threatened...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...
Abstract (from ScienceDirect): Forest managers require climate adaptation strategies that are regionally relevant and translatable into planning processes. Adaptation frameworks, such as the resistance, resilience, transition framework, can guide the development of these strategies. However, there are limited examples of how these concepts can be operationalized with concomitant estimates of changes in forest structural complexity and diversity, which may support adaptive capacity. To address this knowledge gap, two operational-scale, replicated experiments were studied to understand how application of the resistance, resilience, transition framework influences stand structure in two contrasting northern forests:...

Winter conditions have changed substantially in the Great Lakes region over the last 50 years, with the region experiencing rising temperatures, declining lake ice cover, and increased lake-effect snow. These changes have direct implications for economically important wildlife, such as deer and waterfowl. Deer hunting alone contributes $482 million annually to Wisconsin’s economy. The goal of this project was to identify how winter severity, snowpack, and lake ice could change through the mid- and late-21st century, and how species such as the white-tailed deer and mallard duck will respond. Because currently available climate data is at too coarse a scale to provide information on future conditions for the Great...
