We still need building materials, and trees are cut down all the time for building materials and paper. Besides, wood decays very, very slowly. There's a couple trees nearby that were felled 25 years ago, and they are just starting to rot.
Besides, they don't have to be buried that deep. People are still finding intact bodies in bogs in England from thousands of years ago. They're just a few feet down.
In the desert things decay pretty slowly, too. See Sylvester, the cowboy mummy in a museum in Seattle that was found in a sand dune in Arizona with a bullet hole in him.
