Horn Island Preserve Updated:02/2024

The primary boundary of this 2,763-acre preserve is one mile North and South of the island and is bounded on the East and West by the Alabama state line and the Gulfport Mississippi shipping channel. This large barrier island is made up of subtidal estuarine habitat near shore, barrier island marsh/pond/lagoon complex with pine-oak maritime woodland inland, and sea grass beds and mollusk reef off shore. This unique location provides excellent feeding, resting, and wintering habitat for numerous types of neotropical migrants and wintering waterfowl species, and is also known to be a rookery and nesting area (see below). Lands within this Coastal Preserve are federally owned. The island is part of the Gulf Island National Seashore and managed by the National Park Service.
