This webinar will discuss findings from the Grasslands Synthesis Project, recently published as USGS Open File-Report 2023-1037 and USGS Open File-Report 2023-1036. Grasslands in the Great Plains are of ecological, economic, and cultural importance in the United States, and understanding how climate change and variability will impact these ecosystems is crucial for successful grassland management in the 21st century. In 2020, the NC CASC began a project to establish a baseline of information to best serve grassland managers at Federal, State, and Tribal agencies and nongovernmental organizations to help meet regional grassland management goals. This project, “A Synthesis of Climate Impacts, Stakeholder Needs, and Adaptation in Northern Great Plains Grassland Ecosystems'' (hereafter, the Grasslands Synthesis Project), had two primary goals: (1) to synthesize management goals and challenges for grassland managers across the region and (2) to assess the state-of-the-science and identify knowledge gaps for addressing the goals and challenges within the context of climate change. Two working groups and an advisory committee worked for two years to collect, analyze, and synthesize existing reports, peer-reviewed literature, and management documents. We identified 70 specific research questions organized into 15 categories of research needs that, if answered, would support grassland managers in meeting their management goals under a changing climate. Those research questions were then used to guide a synthesis of available information on the impacts of climate change and variability on temperature, water availability, wildfire, vegetation, wildlife, large-bodied ruminants, grazing, and land-use change and the implications for grassland management in the North Central region. We will discuss these findings, remaining research needs, and next steps in this research.
