PARTS OF CONTEST:

Written Test (200 points)Test will consist of general knowledge questions about forestry terms, measurements, pests, etc., which will come from the listed publications. Primary references include: Forest & Forestry Text and Kentucky Division of Forestry Website. Extension publications, textbooks, and other websites may also be used as references.

Tree Identification (200 Points)Participants will identify 25 trees from the attached list.

Timber Cruising (250 points)Participants will measure 10 trees. For each tree, participants will record DBH (Diameter Breast Height) to the nearest one-inch class and the merchantable height of each tree height rounded down to the nearest ½ log. Volume tables will be provided for the event. The minimum diameters and log lengths will be:

DBH 10 inchesTop Diameter 10 inches DIBHeight 16 feet

Merchantable Height stops are estimated to the upper point on a tree where it becomes 10 inches in diameter or where a major fork in a tree stem occurs or where a limb has a diameter equal to ½ of the diameter of the tree at that point.

DOYLE LOG SCALE WILL BE USED.

1. Points per tree: 10 - DBH; 10 - # logs; 5 - board feet.2. Measure DBH to nearest inch.3. Measure merchantable timber to the nearest ½ log4. 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.

Even Year PracticumsThe following practicums will be used in even numbered years (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)Participants will answer questions using a furnished United States Geological Survey topographic map. The participants should know the legal description, recognize topographic map symbols, understand the meaning of map symbols, size and location of 40 acres or more in a parcel.

Forest Products (100 points)Ten to twenty wood products/samples will be displayed for participants to evaluate and identify its tree species source from the tree identification specimen list. The wood products/samples will be presented as actual samples, pictures/slides, and/or written descriptions. The National FFA Tree ID Specimen list will be used for Forest Products.

Odd Year PracticumsThe following practicums will be used in odd numbered years (2015, 2017, etc.)

Tool ID (100 points)Tools to be used will be those on the national contest tool list. There will be 20 tools from this list to identify.

Compass and Pacing (100 points)The participants will use a hand compass and pacing to the nearest full foot to simulate the determination of the property lines on a tract of timber. The participant will start at any point and record the compass reading and distance to the next point. Azimuth readings shall be recorded. Partial credit will be given with a deduction of one point for each two degrees or two feet the participant is off the correct answer.

Tree Forest Disorders (100 points)Symptoms of 10-20 disorders from the attached list will be displayed for the participants to identify by common names. The symptoms may be presented in any of the following forms: actual samples, pictures/slides, written descriptions, and/or written case history.

2013 TIMBER STAND IMPROVEMENT (TSI) WORKSHEETStand 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
