Coastal wetlands in Sierra Leone were censused for bird numbers during the period January/February 2005: Scarcies Estuary, Sierra Leone River Estuary, Yawri Bay, Turtle Islands and Sherbo Island.
In total 94,000 waterbirds were counted and more than 115,000 were estimated to be present in coastal brackish and marine wetlands. Based on the results, all areas met the ornithological criteria to be listed as Important Bird Areas (IBA's) or as Wetlands of International Importance (Ramsar Convention).
During the trip 11 villages were visited for extensive discussions with local authorities about conservation topics. From these interviews information was collected about the occurrence of other species (groups) e.g. marine turtles, manatees. Also interviews were taken on hunting pressure and willingness to conserve threatened species.
