  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.
