What we have done is to cut the trees at/near ground level, use the branches and trunks to make hugel-style raised beds 2-3 feet high. The roots and wood will eventually rot and create wonderful soil. Our plot of pine woods had been logged about 35 years ago so the size of the trees has been pretty manageable. We also had piles of soil that they scraped off pathways for their trucks. We used this in the garden beds.
We haven't tilled and don't plan to. Too many rocks, and with building up there is no need. We've gotten very good plant growth in these beds so using pine and fir hasn't been a problem.
