Other habitat components are the summer habitat, where snakes move and forage, and transient habitat located in between summer habitat and the den (Brown, 1993). I normally would. Because females do not mature until about eight years old and reproduce on average only once every three years (Martin, 1993), most females will give birth to no more than five broods throughout their lifetime, assuming a lifespan of 22 years (Brown, 1991).
