Impacts on Ecosystems

USGS science is essential for resource managers and policymakers to understand the implications of climate and ecosystem change and make well-informed, science-backed decisions. Working with natural and cultural resource managers, USGS scientists provide tools to help fish, wildlife, ecosystems, and communities anticipate, plan, and adapt to the impacts of climate and environmental change.
