The Plum Island Preservation Study Act aims to assess the future of Plum Island, a federal property in New York. The main objective is to determine whether all or part of the island should be designated as part of the National Park System or the National Wildlife Refuge System, or if other protective measures should be taken to preserve its resources. Key provisions of the Act require the Secretary of the Interior to conduct a comprehensive study of Plum Island. This study will evaluate the island's national significance and explore various options for its protection.
