Sugar Island – Fredericton, NB
Keswick, York County
This preserve is approximately 8.1 hectares (20 acres) and is located at the eastern end of Sugar Island. This island is one of the Keswick Islands in the St. John River, above Fredericton and below the Mactaquac dam.
Sugar Island Preserve was donated to the Nature Trust in 1996 by the H.M. Dignam Corporation of Ontario and Prince Edward Island.
The floodplain islands (Sugar and the adjacent islands) have an unusual floodplain and prairie-type flora. The gravel strands, which are flooded annually, are effectively in a state of perpetual early succession. Rare plants occurring on the strands of these islands include: Brunet’s milk-vetch (Astragalus alpinus var.brunetianus), beard grass (Schizachyrium scoparium), Lake Huron tansy (Tanacetum huronense), and tall dropseed (Sporoblus asper). The western end of the island, above the gravel stand, has been used for grazing and does not host the variety of plants, though the Nature Trust may reintroduce some of these species in future planning.
