I live in a forest primarily made of oak trees. I fight "leaf wars" every year. For 15 years I have mulched the majority on a very large lawn.
The leathery leaf must be chopped as small as possible. It is a favorite food source for earthworms. Their castings and leaf mold help dress the soil and is fertilizer for grass and feeder roots of trees.
An oak leaf that is still whole, if left on the ground or in bare spots in the lawn, will stay there, blocking grass growth for many years. Rake them loose and mulch.
A very good mulching mower is a necessity. The mower blades will dull and need sharpening a time or two. The dust will clog the air filter so check and clean it often. Wear a dust mask. The result is a lush green lawn.
The down side: The worms loosen the soil so well that local moles will tunnel through your yard. No damage just unsightly. Poke holes in their tunnels. They don't like air and light and will abandon that one. Continuing this until they return to the woods may take a while.
I do blow mass amounts of oak leaves back to the wood line. That "berm" is gone, composted by the next War.
I must return to the war. Good luck!
