Fallen leaves provide shelter for a multitude of animals including earthworms, pillbugs, and millipedes. These animals provide food for frogs, toads, and other small animals. As winter draws near, the leaf litter becomes a warm blanket which helps these small animals to survive the cold.
Consider leaving a leaves on a portion of your lawn to increase the fauna of your yard. The frogs and other small animals will thank you and reward you with more wildlife sitings in the coming year.
