Resilient Coastal Sites for Conservation in the South Atlantic

“Resilient Coastal Sites has the potential to catalyze a host of proactive steps by local communities concerned about the long-term prospects for their coastal resources.”
-Wendi Weber,

Coastal sites vary widely in their ability to accommodate rising seas, based on inherent natural features and the degree of human influence on key ecological processes. Scientists from The Nature Conservancy evaluated over 1,200 coastal sites in the South Atlantic for their capacity to sustain biodiversity and natural services under increasing inundation from sea level. Each site received a resilience “score” based on the likelihood that its coastal habitats can and will migrate to adjacent lowlands. The products of this study include: 
  • A report describing the methods used to evaluate sites and the results for each coastal shoreline region in the South Atlantic 
  • A web tool allowing users to view and interact with the results for any coastal site 
  • A story map allowing users to explore a variety of coastal conservation strategies such as land acquisition, restoration, enhancing productivity, prioritizing buy-outs, and others 
  • Downloadable datasets including results for additional sea level rise scenarios 

South Atlantic Findings:  With no action, the region could experience an estimated 77% loss of existing tidal habitats to severe inundation. However, there are many sites where tidal habitats could increase and expand through landward migration, reversing this trend. With conservation and management, these resilient sites have the potential to offset almost 80% of the estimated tidal habitat loss, providing critical habitat for birds and other wildlife, and buffering communities from the effects of storms and floods. Conservation of these resilient sites is critical if we are to sustain nature’s diversity and benefits into the future.
