Depending on WHERE you live in New England, you may begin to see VERNAL POOLS in your more "rural" areas. If you have a large yard, you may even be fortunate enough to have one there somewhere. Often people don't like seeing those spring-time puddles that appear EVERY year at about the same time, but, you shouldn't be too quick to fill them in, or plow them up. There are many little creatures that rely on those yearly puddles to reproduce, or in the case of flowers, to bloom and grow!
