- If two oaks are crowding each other and one is a red oak and the other is a white oak, remove the one that is more prevalent in the entire woodlot.
- If the trees are of the same type, remove the one that has a history of producing less mast since it probably lacks the genetic potential for high acorn yields.
- If no discernable differences exist between two similar trees and they're growing on a slope, remove the oak that sits lower. Frost tends to settle in low areas, which means that oaks growing in low spots are most vulnerable to frost damage. One study revealed that as little as a two-foot rise in elevation is enough to prevent frost damage in trees.
