The
Isles Dernieres Barrier Islands Refuge encompasses four islands: from east to west, Wine, Trinity/East, Whiskey, and Raccoon, as well as several thousand acres of associated water. There is a public use area for bird-watching, picnicking, fishing, and overnight camping on Trinity Island; any other use of the islands requires a permit from the Louisiana Department of Wildlife and Fisheries, which owns the islands and has managed them since 1992, when they were initially leased from the Louisiana Land and Exploration Company. Today, the islands protect the mainland to the north from erosion and damage from hurricanes, but their primary purpose is to provide protected habitat for nesting waterbirds, such as
pelicans. Raccoon Island in particular is one of the most important waterbird nesting areas on the Louisiana Gulf Coast. ==References==
