Another reason to Leave the Leaf Litter

We all know by now that leaf litter is important for overwintering pollinators and other insects. (Right? We do all know that, don't we?) Those "dead" leaves are often home to lepidoptera eggs, which give us next season's butterflies and moths. Our human penchant for tidy lawns is almost certainly one reason why we see fewer colorful insects today than some of us remember from our childhoods.

Leaf litter hides seeds, dried berries, worms, and insects, serving as a buffet for the birds that eat such things. There is a reason some species are known as "thrashers."

And we know that leaf litter is natural mulch, reducing the need for water and cutting down on the gardener's work. Best of all (at least for those of a thrifty--not to say cheap-bent), it is free, letting us spend our money on more plants rather than on shredded hardwood. 

But today, walking at a favorite park, I was reminded of another Very Important Reason to Leave the Leaves: they provide shelter and protection from predators for small creatures. Admiring the baby sassafras and fading mayapples at this overlook,




I kept hearing rustling sounds and seeing tiny eruptions of leaves. Suspecting that wildlife was present but unable to see any (because of all that leaf litter), I hung around until finally being rewarded with the sight of the creature I thought was most likely responsible: a large and handsome chipmunk, who did not hold still long enough for a photograph. (Plants are so much more cooperative in that respect.)

This favorite park is home to some quite beautiful predators, including the Cooper's hawk sighted a few hundred feet away in a sunny area, but leaving the leaves for cover gives the little guys a chance. And when there are lots of them, that is good for the predators as well, not to mention good for those of us who delight in watching the critters.

A little laziness is a good thing.
