Coastal change is an important issue for all coastal regions of the LCC Network, yet there are vast differences in the tools and information available across coastal regions. While the key uncertainties may differ across the Network, all coastal LCCs have been working to advance coastal resilience and adaptation. In some coastal areas, there are significant resources available to communities to understand coastal change and the discussions are now focused upon adaptation and incorporating natural resource considerations. In other regions, few tools exist for either communities or resource managers to address observed and predicted coastal change. The ultimate goal for LCCs is to have decision makers informed about...

The impacts from climate change are increasing the possibility of vulnerable coastal species and habitats crossing critical thresholds that could spur rapid and possibly irreversible changes. For species of high conservation concern, improved knowledge of quantitative thresholds could greatly improve management. To meet this need, we synthesized information pertaining to biological responses as tipping points to sea level rise (SLR) and coastal storms for 45 fish, wildlife, and plant species along the U.S. Atlantic and Gulf Coasts and Caribbean through a literature review and expert elicitation. Although these species were selected based on their ecological, economic, and cultural importance, just over half (56%,...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
