Island Enhancement

A 17-acre man-made atoll transformed into sustainable bird habitat.


  • Reduce erosion along the eastern shoreline.
  • Enhance island resilience to sea-level rise.
  • Enhance habitats for shorebirds, waterfowl, and wading birds.
  • Enhance suitability of haul-out habitats for harbor seals.
  • Enhance habitats for rare salt marsh plants.
  • Establish native vegetation on the island terrace.
