The roots arc above the tidal mud like architectural ribs, grey and woven, clearing salt from the sea and holding the coastline in place against storm surges that would otherwise scour the land. For millions of years the mangroves of coastal Ecuador did this work quietly, turning seawater into fresh breeze and providing nurseries for shrimp, fish, and the migratory birds that move up and down the Pacific flyway. Then in the 1970s and 1980s, the shrimp farms came, and the forests fell. The Manabi mangroves now carry the designation Critical/Endangered from the World Wide Fund for Nature. Thirty-eight percent of what remains is in critical condition.

Through the 1970s and 1980s, farmers cleared vast tracts of mangrove forest to build the shallow coastal ponds where Pacific white shrimp would be raised for export. The ecological damage was enormous. In ...

In the mud, nematodes and polychaete worms break down mangrove detritus into protein that feeds crabs and small fish. Larger fish and shrimp migrate through the roots during their reproductive cycles, using the tangled roo...

Manabí Mangroves: Conservation Without Protection

Photo credit Every-leaf-that-trembles, CC BY-SA 4.0. Despite their ecological importance, the Manabi mangroves sit in an unusual legal limbo. In 1989, the National System of Protected Areas declared them a priority, but no protected area formally covers them. Enforcement of the 1985 shrimp farm ban has been uneven. Sedimentation ca...
