Preserve and restore structural complexity and biological diversity when undertaking wetland enhancement activities. Ecological diversity is widely recognized as making habitats more resilient to climate change. By managing for diversity and incorporating climate change projections into restoration planning, land managers will be better able to protect critical estuarine habitats, such as nursery and spawning grounds. A diverse Puget Sound estuary contains a mosaic of wetland habitat types, including eelgrass meadows, tidelands, salt marshes, scrub-shrub wetlands, and forested wetlands, such as were present before Euro-American settlement and subsequent wetland destruction beginning in the late 1800s.
