Middle Becaguimec Island is a 2.83 hectare (7 acre) nature preserve located near the Town of Hartland, Carleton County where the Becaguimec Stream flows into the St. John River. It is located between the Hugh John Flemming Bridge on the Trans-Canada Highway and the Hartland covered bridge


Born in Hartland in 1921, Dr. Joseph Kyle, an ophthalmologist who practiced in Niagara Falls, Ontario, donated Middle Becaguimec Island to the Nature Trust in March 2004 to protect and preserve the island for the benefit of nature and future generations of New Brunswickers.


The island is a gravel bar, submerged for a portion of the year, with a wooded and shrub-covered area at the southern end. It is home to the Anticosti Aster (Symphyotrichum anticostense), which is federally listed as a threatened species. This nature preserve gave the first formal protection to this plant, which has a range from the upper shores of the Restigouche and St. John River, to the Gaspé Peninsula, Anticosti Island, and northern Maine.  The Anticosti Aster is a slender perennial plant that grows 50-60 cm tall. Its small daisy-like flowers bloom in late summer, have a yellow centre and pale purple or blue outer rays, and occur on very long stalks. The leaves are narrow and often arching. The Anticosti Aster is dependent on cyclic disturbances caused by spring high waters to keep shrubs and other competing species from taking over the habitat and gradually eliminating the aster.

This preserve is also a home to the endangered cobblestone tiger beetle (Cicindela marginipennis). The island provides a favourable habitat for the cobblestone tiger beetle because it is an alluvial floodplain and is partially submerged annually. The cobblestone tiger beetle is endangered because of its limited geographic distribution and small population. The specific habitat for the cobblestone tiger beetle is formed by flooding during the spring freshet and the water flow patterns created by the presence of nearby islands and beaches. This island is monitored by a network of local stewards who help to keep an eye on it and report any disturbances to the Nature Trust.

Becaguimec Island is also home to Brunet’s milk-vetch (Astralagus alpinus), stemless locoweed (Oxytropiscam pestris), blueflag iris (Iris versicolor), and giant Jerusalem artichokes (Helianthus tuberosus).

Access and Activities

Because of the endangered cobblestone tiger beetle, please view this island preserve and its fauna and flora from the shore or from a canoe on the beautiful St. John River. A convenient place to view the island is from the Trans Canada Trail in the local park located across Mill Street in Hartland.
