I also think that many have already identified the seeds, and possibly saplings, of the next bust. 

I don't want to grow into a sapling, I want to grow into a mature oak tree.

I just spent all weekend with a rented tracked skidsteer loader with a monster bushhog cutting this bamboo down and grinding it up . it was more than my kubota's bushhog could handle , I still have at least another day with a york rake to clean up and pile the stuff up .At least I can pile it in the back of the lot , it would fill about six 40 yd cans .The fun part was this skidsteer and bushhog ripped thru the bamboo and it would grind up 4 inch saplings , I knocked over a couple trees roots and all came up .

The house is in pretty nice shape, but the lakefront is mucky and  full of weeds and saplings. 

The small sapling shouldn't be a problem.

They will stand on hind legs and chew small limbs off clearing understory and they spread their front hooves walk up small trees or saplings and eat all leaves and branchesAll they need is a water source ,I have used them several times where it  was fenced goat owners may be looking for forage for them.

A bushhog will do a rough cut , but they can cut tall grass vines and saplings up to 2 to 3 inches depending on the size of the machine . 

. - If you planted trees each year for 10 years before you started harvesting, you could eventually use the money that you sold the trees for to buy more saplings and keep planting.
