15 years ago I noticed many new oaks growing on a flat that was mostly cherry and maple. A friends son and I cleared that flat of most of the Cherry and maple, and left the Live, Red and White Oaks to grow. Currently have been cleaning out the Birches that are popping up. Some day if left to grow it will be an awesome oak flat.
Another area has a relatively young stand of Reds and Whites. Cleared all the junk and undesirables from there for firewood this year.
The birches seem to be trying harder than the Maple to take over on my place.
For many years I gathered acorns from a colossal stand of Red Oaks and spread them around my place.
The difference between dreamers and achievers is action.
One try is worth a thousand guesses.
