Kettle Island located in the Rivière des Outaouais is made up of contemporary fluvial deposits (stratified sand, silty deposition, organic matter) with flat relief . Wetland are also present in the forest. At the edge of the island, we find riparian habitats. Two forest stands are outstanding forests :the butternut stands with western hackberry, and the silver maple stands in flood-prone areas. The island is also part of the muskrat habitat.
The diverse forest environments, swamps and riparian areas associated with the river provide diverse ecological niches that promote the reproduction and development of many wildlife species and plant species. In addition to having great forests, the island provides a refuge for certain rare species.
