Blanding’s turtles tend to spend the winter months in the muddy areas of deep marshes, backwater pools, ponds and streams. But in early spring they come out and move to temporary wetlands that allow for mating and breeding habitats. Mating will typically occur around early evening, but can go on until late night. They become sexually mature around the age of 12 years. When breeding, they breed only once a year and they typically have an egg clutch of about 10-26 eggs.
