 The bog turtle's preferred habitat, sometimes called a fen, is slightly acidic with a high water table year-round. The constant saturation leads to the depletion of oxygen, subsequently resulting in anaerobic conditions. The bog turtle uses soft, deep mud to shelter from predators and the weather. Spring seeps and groundwater springs provide optimum locations for hibernation during winter. Home range size is gender dependent, averaging about 0.17 to 1.33 hectares (0.42 to 3.29 acres) for males and 0.065 to 1.26 hectares (0.16 to 3.11 acres) for females. However, research has shown that densities can range from 5 to 125 individuals per 0.81 hectares (2.0 acres). The range of the bog turtle extensively overlaps that of its relative, the wood turtle.
