Habitat Restoration

Habitat restoration is the active rehabilitation of degraded marine habitats to recover their structure, species, and ecosystem function. Techniques are habitat-specific: replanting seagrass and mangroves, deploying oyster and coral substrate, removing barriers, and restoring tidal flow to salt marshes. It is the third tier of the mitigation hierarchy (avoid, minimize, restore, offset) and the basis of blue-carbon and damage-recovery programs such as US Natural Resource Damage Assessment. Success depends on treating the original stressor first; restored biogenic habitats like reefs and meadows can take years to decades to reach reference condition, and many projects fail when site selection ignores hydrology.
