The Green Island Nature Preserve is an ecologically significant island located north of Florenceville, in the northwest part of the province in the Saint John River Valley, and consists of over 8 hectares (20 acres). This island provides critical habitat for many Species at Risk, listed federally and provincially.
The island was used by First Nations people and was subsequently occupied by early settlers.
In 2014, Green Island Nature Preserve received designation as a Class II Protected Natural Area (PNA) under the province of New Brunswick’s PNA Act, providing the land with additional protection, including subsurface materials. For more information about PNAs, click here.
Green Island is a combination of wetland and woodland. About half of the island is forested with Acadian forest type trees and understory. Some of the species found include the endangered Butternut tree, Mountain Maple, American Elm and Paper Birch. The Northeastern portion of the island contains a provincially regulated wetland.
It is home to the Anticosti Aster (Symphyotrichum anticostense) which is federally listed as a threatened species.
Access and Activities
The island is accessible by boat only. Because of the endangered species found on the island, visitors are encouraged to view the island from the shore or to paddle around the island. The best view is from the Trans-Canada Trail near Florenceville-Bristol, or from Route 130 on the west side of the Wolastoq (Saint John) River.
*The property is undeveloped and there are a variety of hazards and risks associated with accessing this preserve. While this nature preserve is open for public access, visitors must assume responsibility for their own actions and safety and are to use the land at their own risk.
