  2. Food Medicines Fuel Shelter Protection Shade Tools Over 10,000 products made of and from wood One of the most important renewable resources on the planet TREES PROVIDE:

  3. ENVIRONMENTAL: • Cleaner, Cooler Air • Absorb carbon dioxide, trap dust, ash, pollen & smoke • Provide shade which reduces temperatures • One acre of trees produces enough oxygen for 18 people every day

  4. Prevent erosion • Act as natural water filters • Slow movement of storm water • Lowers total runoff volume • Reduces soil erosion • Reduces flooding • Reduces moisture loss from the soil • Controls runoff of rain water • Helps regulate streams, rivers & lake temperatures Provide wildlife habitat

  5. ECONOMIC • Enhance economic stability by attracting businesses & tourists • Increases property values, as much as 15 % • Reduce summer cooling costs by as much as 30 % • Heating costs can be reduced by the use of trees as windbreaks.

  6. HEALTH • Increases outdoor activities which can reduce health problems such as heart disease & diabetes • Reduce ADHD in children: better able to concentrate & follow directions after playing in natural settings • Reduce conditions that cause asthma

  7. HISTORY • Provided building materials, clothing food and medicines to survive • 975 million acres of forest in 1600’s • 749 million acres of forest today (77% of the land that was forested in 1600) • 1st sawmill established in Jamestown, Virginia in 1625

  8. Sawmill industry started in the south around 1803, developed into a major industry in 1895 with increase in population • Lumber production peaked in 1909 with 50,000 mills employing 500,000 workers

  9. FOREST FACTS IN THE UNITED STATES • 33% of the U.S. is in forests • Contain over 800 species of trees of which 82 are non-native • Of 749 million acres, 504 million acres are suitable for timber management • 71% of timberland is privately owned

  10. Public forest comprise 29% of timberland • 2.1 billion seedlings planted in 1989 • Top 5 states in planting in 1989 were Georgia, Alabama, Florida, Mississippi & South Carolina • Growth exceeds harvest nationally by more than 37% • Forest industry has annual sales of more than $195 billion • Industry employs about 1.3 million people

  11. Paper industry employs about 620,000 people with annual sales topping $122 billion • In hundreds of rural communities, the forest products industry is the leading or only employer & major source of revenues which supports schools, roads & other local government services

  12. Georgia as a forestry leader • Georgia contains the largest area of forest cover in the South with 67% of the State being in forests • Of 159 counties, 131 are greater than 50% forested • Private landowners control 92% of the forests

  13. Loblolly-Shortleaf & Longleaf-Slash comprise more than 99% of the softwood types • Planted pine represent 60% of the softwood forest • Timber is the highest valued vegetative crop in Georgia • Georgia is the first state in the nation ot license foresters

  14. FORESTRY TERMS ACRE-a unit of land measurement consisting of 43,560 square feet or 10 square chains AD VALOREM TAX-annual taxes assessed by local county government on the basis of land & timber value ANNUAL RING-a ring of wood put on each year by a growing tree; indicating the growth for the period of one year.

  15. BEST MANAGEMENT PRACTICES (BMP’s)-practice or combination of practices to be the most effective, practicable means of preventing or reducing the amount of pollution BOARD FOOT-a unit of timber measure equal to a piece of board one foot square by one inch thick. Used as a measure when estimating the amount of lumber in trees

  16. BOTTOM LANDS-land, usually flood plains, adjacent to a river or water CATFACE-a scar on a tree resulting from turpentine operations CHAIN-a unit of measure 66 feet or 4 rods long CHIP-N-SAW-trees larger than pulpwood but smaller than saw timber trees

  17. CLEAR CUT-a harvesting method that removes all tress regardless of size from an area COMMERCIAL FOREST LAND-land capable of producing timber for industrial use COMPETITION-the struggle among trees for growth requirements such as sunlight, nutrients, water & space

  18. CONIFER-a tree bearing seed cones, usually an evergreen; Gymnosperm CONSERVATION-the protection, improvement & wise use of natural resources to provide the greatest social & economic value for the present & future CONTROLLED BURNING-any burning intentionally started by the landowner to accomplish some particular purpose

  19. CORD-a volume measure of stacked wood; 4’ x 4’ x 8’ or 128 cubic feet of wood bark & space CROWN-the expanse of branches, twigs & foliage of a tree; the tree top DECIDUOUS TREE-a tree that drops its leaves at some time during the year, usually in the fall

  20. DIAMETER BREAST HEIGHT (DBH)-the diameter measure of a tree taken at 4 ½ feet above the ground EVEN-AGED FOREST-a forest containing trees with relatively small age differences FIREBREAK-a plowed barrier designed to stop an advancing fire

  21. FOREST MANAGEMENT-giving the forest proper care so it stays healthy, vigorous & provides the products & values the landowner desires VIRGIN FOREST-forest mature or overly mature & uninfluenced by human activity FORESTER-a professionally trained individual who manages a forest

  22. GYMNOSPERMS-botanical name for the group of plants that includes the so-called softwoods HARDWOODS-a term generally including all species of trees that loose their leaves in the winter HARVEST-removing trees from an area

  23. HEARTWOOD-the wood in the interior of the tree where cells no longer participate in the life processes of the trees HIGH-GRADING-the practice of harvesting only the biggest & best trees from a stand INTOLERANCE-the incapacity of a tree to develop and grow in the shade of & in competition of other trees

  24. LOG-to cut & remove tree logs from an area LOGGER-a person engaged in logging operations MARKING TIMBER-selecting and indicating by paint, trees to be cut or retained in a cutting operation
