Those of you who have to shovel snow are probably asking what in the world am I talking about?
Snow has a crucial role in the environment.
Snow is the winter equivalent of rain. It helps replenish all the water that we've used over the warmer months and keeps plants hydrated. While plants may need less water in the winter they still need some. Plus it slowly trickles into our reservoirs and underground water systems so that there is an ample supply in the springtime.
In addition to that it provides insulation to plant roots. Some plants will die if their roots freeze or have too many freeze/thaw cycles so this helps to prevent that.
A layer of snow will help protect various forms of bugs and insects that are overwintering in the leaf litter on the ground. Remember you were supposed to leave your leaves!
Finally it provides an environment for small animals. Moles, mice and other small creatures create tunnels throughout the snow. This gives them safe travel from place to place as well as protection from predators that can't see them now.
An added bonus is that it's just really pretty. So get out there and enjoy the snow. Build a fort, take pictures, have a snowball fight, but just have fun.
