As a member of the Organization of Eastern Caribbean States (OECS) formed in 1981, Dominica shares environmental problems common to the area's island countries. Water shortages are among the most significant. Other areas of concern are pollution from chemicals used in farming and untreated sewage. The nation's forests are endangered by the expansion of farming activities.
Pollution of the nation's coastal waters threatens the tourist trade in the area. Two extensive areas have been set aside as nature reserves. The southern reserve, which constitutes Morne Trois Pitons National Park, covers an area of 6,500 hectares (16,100 acres). In it are the nesting places of the red-necked and imperial parrots, both endangered species of Dominica; the tundra peregrine falcon and the green sea and hawksbill turtles are also classified as endangered. Hurricanes are the most destructive natural threat to the environment.
