Overview
Seagrass restoration starts from a different set of problems than mangrove restoration, and often a harder one: the meadows are underwater, slower-growing, and their decline is driven by different pressures than a degraded mangrove shoreline.
How Seagrass Restoration Differs From Mangrove Restoration
Before any restoration intervention is designed, the drivers of seagrass decline at a given site need to be understood. Anchoring damage, trawling, sediment disturbance and declining water quality each degrade seagrass meadows in different ways, and the appropriate response to each is different.

Why Seagrass Restoration Is a Discipline of Its Own:
- Underwater, Not Shoreline, Work
Mangrove restoration happens largely at or above the waterline, where it can be inspected and protected relatively easily. Seagrass restoration is underwater work: transplant success is more variable, growth is slower, and monitoring requires different methods and more frequent site visits.
- Restoration and Protection Together
Because ongoing pressures like anchoring and trawling can undo restoration work as fast as it is done, seagrass restoration is rarely just a planting activity. Restoration and protection measures need to be applied together and supported by ecological monitoring.
- A Discipline of Its Own
This is why Twende treats seagrass restoration as its own discipline within its Blue Carbon work, not an extension of mangrove restoration methods applied underwater.
- Climate and Coastal-Economy Value
Seagrass meadows also carry their own climate and coastal-economy value on Kenya’s coast, which is covered in more depth elsewhere in the Knowledge Hub.
