Ill. Admin. Code tit. 17, § 1536.55 - Pruning Hardwood Crop Trees
The purpose of pruning is to improve the quality and quantity of crop trees in a forest stand.
a)
Acceptable pruning of crop trees is corrective pruning to a single leader with
side branch pruning. The flat rate payment for this practice is $105 per acre.
The base cost is $140 per acre.
b)
The IDNR Forester must give prior approval of a practice area with individual
trees marked and/or having a detailed written prescription addressing a minimum
of 40 crop trees per acre having a minimum of 4 inches diameter at breast
height (DBH).
c) Prune to total
height of 17 feet and retain at least 40% of total tree height as live crown.
Prune no live limbs over 3 inches in diameter.
d) All pruning final cuts must be targeted as
close to the stem as possible without disturbing the branch bark ridge and
branch collar. Assure that no branch stubs or flush pruning cuts are left on
pruned trees.
e) Corrective pruning
to influence tree form may be required in the Plan during the establishment of
a forest stand. Early corrective pruning shall not be cost-shared unless
undertaken along with side branch pruning as described in this
Section.
