A common recommendation as to how to manage fallen leaves in autumn is to simply ignore them. The idea is that as they decompose, they'll nourish one's yard, helping to provide the requisite nutrients for a healthy lawn in the spring. It doesn't hurt that this strategy also appeals to humanity's general propensity towards laziness—and don't even get me started on leaf blowers. However, I can't imagine that supporters of this school of leaf management have seven large ash trees in their yard like I do.
