Seychelles began addressing the conservation problem in the late 1960s by creating the Nature Conservancy Commission, later renamed the Seychelles National Environment Commission. A system of national parks and animal preserves covering 42% of the land area and about 260 km2 of the surrounding water areas has been set aside. Legislation protects wildlife and bans various destructive practices. In Seychelles' 1990 to 1994 National Development Plan, an effort was made to include in the appropriate economic sectors of the development plan environment and natural resources management aspects.
