The northern third is currently an undeveloped State Park with no access except by boat. A bridge, boat landing, and other facilities are planned for the site in 1998. The northern tip of the island is crossed by major highway and railroad bridges. The site hosted at least 13 breeding pairs of Cerulean Warblers in 1997 and area has been used by Ceruleans since at least 1965.
Ospreys regularly use area for roosting and perching.
A Great Blue Heron rookery on the island hosts 50-75 birds. This area was previously inaccessible and undeveloped, but there are current plans for a bridge to the island with a small boat launch, picnic area, and camping area. The current plans do not impact any sites where Cerulean Warblers were present in 1997. Few of the mature trees which the Cerulean Warblers prefer will be removed by the development plans and there should be little or no impact to the species. Increased access to the southern portion of the island where Bald Eagles regularly roost should be discouraged, as should plans that greatly increase human disturbance.
