Mangrove Forest River Corridors

June 14, 2026 claymatics.web@gmail.com West Coast Southwest

Overview

The mangrove forest river corridors of the southwest coast — the continuous mangrove fringe systems of the Bentota, Kalu, and Maduganga river systems and their associated tidal channels — collectively form the most extensive accessible mangrove ecosystem in the Western and Southern Provinces. These corridors provide critical habitat for estuarine species, nursery habitat for coastal fisheries, and bird habitat of considerable quality. The boat safari through any of these mangrove corridors reveals a world of extraordinary natural calm just behind the busy coastal highway.

Highlights

  • Continuous mangrove fringe systems connecting multiple southwest coast rivers
  • Critical nursery habitat for the coastal fisheries
  • The most extensive accessible mangrove in the Western and Southern Provinces
  • Each river corridor has a distinct character
  • Kingfishers, herons, and specialist mangrove birds throughout

  • The boat safari reveals a world invisible from the coastal highway
  • The ecological connection between river, mangrove, and sea
