Points per tree: 10 - DBH; 10 - # logs; 5 - board feet.
Measure DBH to nearest inch.
Measure merchantable timber to the nearest ½ log
There will be a 1" leeway on DBH worth 1/2 credit (5 points).
There will be a ½” log leeway on number of logs (5 points) ½”
log = 8 ft.; 1 log = 16 ft.). Board feet must be exact according to
the official judge's measurements.

(2014, 2016, etc.)
Timber Stand Improvement (100 points)
Participants will be given a scenario and guidelines about a tract of timber.
They will then be given 10 trees and asked to identify each tree as: Crop Tree,
Deaden Tree, Leave Tree. An example scenario is attached.
Map Interpretation (100 points)

10. 2013 TIMBER STAND IMPROVEMENT (TSI) WORKSHEET
Stand Description: The area is typical of an old field (30 plus years ago) that is
reverting to hardwoods. The major tree species noted in this area are; yellow-poplar and
eastern redcedar. The stand also contains other species including sugar maple, red
maple, persimmon, and black cherry. This area is in need of proper forest management
techniques to improve the woodlot for the future.
Goal: Your primary goal is the long term development of high quality timber. Your
secondary goal is to improve wildlife habitat by killing low quality canopy trees to
increase browse on the forest floor. This will be accomplished by deciding which trees
should be left as crop trees (crop trees), which trees should be eliminated to improve
the growth of the crop trees or to meet your wildlife goals (deaden) and which trees are
not impacting your goals and should be left alone (leave).
Hints: A crop tree is a straight tree with few lower limbs and good diameter growth. A
leave tree is a tree that is not interfering with a crop tree and would have limited effect
on the stand if removed. Black cherry and black walnut tend to hold a higher value than
other species.
Circle the action you would take for the selected tree to improve the stand:
crop tree, deaden or leave
