1 Forestry- The Management of Trees Goal of Forestry-  To sustain a balance between our needs (products) and the needs of nature.

2 Forestry Occupations  Federal, State, Local  Landscape, Tree Farms  Logging  Paper  Land Mgmt.  other

3 Why are Forest Impt?  1. Habitat for organisms  2. Produce products that we need ex. Why White Pine?  3. Protect Soil, Erosion, Windbreak  4. Prevent flooding  5. Recharge Groundwater  6.Carbon Trap Produce Oxygen, Clean air  7. Aesthetics

4 Harvesting Decision  1. Calculate the Monetary Value of the trees/forest.  2. Calculate/Estimate the importance of each species by studying populations. Quadrat Method.  3. Predict future effects on other plants and animals  4. Predict future effects on recreational needs

5 Tree Measurements  To Determine the monetary value of trees.  Only measure trees over 6 in. in diameter at DBH.

6 Diameter  Biltmore Stick  Calipers  Tape  Biltmore Stick  Calipers  Tape  Biltmore Stick  Calipers  Tape

7 Height  Only measure usable timber- 6 in.  1 chain equals 66 ft.  Clinometer  Biltmore Stick

8 Sawlogs  1 sawlog equal 16 ft.  Sawlogs are found in whole or half logs  Reduce down to the nearest whole or half

9 Boardfeet  The number of 12” by 12”by 1” boards a tree could be cut into.  Boardfeet Chart –Diameter and Sawlogs used to determine numbers of boardfeet.

10 Worth of the Tree  All types of lumber costs different amounts  Market Value = Board Feet times Cost per Board Feet.  Standing or Stump Value = 1/10 of the Market Value.
