Impressions - Constant Creek Swamp and Fen

This 540-ha conservation reserve contains undisturbed flooded swamps with silver maple, green ash, black ash and cedar. The flatland is a product of a post-glacial spillway that runs from the Lake Clear area to Calabogie Lake, about 7 km west of Calabogie. Constant Creek itself lies overtop of a sand outwash plain. Marble and granite bedrock runs in ridges through the site and create a series of linear wetlands that have grown into fens. There are extensive wild rice stands and an adjoining provincially significant wetland at Ferguson Lake. The swamp-over-marble combination is a distinct feature. The mixture of deciduous and coniferous swamps, interrupted by large and open grassy fens, is the best collection of these habitats in the area
