dedicated for visiting cruise ships. This industry has grown in the 21st century. Ecology Several proposed conservation sites and green areas are located on and around the island. These include Cuskinny Marsh Nature Reserve (which is managed by BirdWatch Ireland), Marlogue Wood (operated by Coillte), and the Great Island Channel Special Area of Conservation (overseen by the National Parks and Wildlife Service). The latter, the Great Island Special Area of Conservation, proposes conservation controls (including aquaculture limits) to protect the animal and bird habitats of the area's salt marshes. While larger fish species are less common in the Great Island Special Area of Conservation, a large blue shark was recorded just off the island in mid-2018.
