ES-07. Climate Impacts, Stakeholder Needs, and Adaptation in Northern Great Plains Grassland Ecosystems

Abstract
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 synthesize 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 also identify remaining research gaps. The findings from this project have been published as two USGS reports. This poster summarizes these key research needs and other results of this project.
