Description - Petit Manan NWR is inhabited with red and white spruce, mixed hardwoods, jack pine stands, coastal raised heaths, blueberry barrens, old hayfields, fresh and saltwater marshes, cedar swamps, granite shores and cobble beaches. This type of habitat invites over 300 birds species each year.
- Petit Manan NWRs wetlands have been enhanced by constructing three impoundments which provide habitat for thousands of waterfowl and wetland associated species. To date, over 300 bird species have been recorded on Petit Manan Point. Bois Bubert Island is much the same as Petit Manan Point in character and wildlife.
Petit Manan Island is a treeless island and lies two and a half miles south of the Point. This island is now one of the most important islands in the Gulf of Maine for colonial nesting seabirds, including the endangered roseate tern, due to a restoration effort conducted jointly by the FWS and the College of the Atlantic. It is also the site of a 123 foot U.S. Coast Guard lighthouse tower and associated buildings that are on the National Register of Historic Places.
Recreation - Viewing wide open scenery of sea and land is enjoyed. With over 300 species of birds visiting this series of islands and mainland, bird watchers find this location rewarding. The lighthouse, which is national recognized, stands at over 100 feet. The first lighthouse at this site was erected in 1817 and the present structure was rebuilt 1855. It is the second tallest in the state.
Climate - Visitors to the Down East / Acadia Region may expect to find daytime winter temperatures averaging above 18 degrees Fahrenheit (above -8 Celsius).
