Major Branch Damage
Occassionally large branches will break off at the mainstem. This can introduce rot into the mainstem. The height above the ground indicates how fast the tree should be cut to recover timber value.
Trees having a major crown branch broken from the mainstem will survive. However, the large wound leads to rot development in the upper section of the stem. Unacceptable growing stock.
Major branches torn within the crown (not torn from the mainstem) will recover. Acceptable Growing Stock or Questionable Growing Stock (based on other choices in the stand).
