1
Management and Use of Forests

• Modified by Agricultural Education Office
• June, 2002

2
Managed Woods

• proper management
• results in greater and more uniform growth than
  when trees are permitted to develop according to
  natures plan

3
Management practices

• planting selected varieties of trees
• some trees may be used for several purposes

4
Management

• rate of growth should be considered
• most important uses timber and veneer

5
Management

• length of time to maturity
• faster growing trees have fewer uses

6
Management

• Eucalyptus - one of the fastest growing
• 15 inches in diameter in 40-50 years

7
Management

• Black Walnut, Oak, Hard Maple
• 100-125 years

8
Breeding Super Trees

• select seeds of trees that are
• fast growing
• tallest
• straightest

9
Breeding Super Trees

• healthiest
• raise super trees in nurseries

10
Controlling Insects and Disease

• can be variety specific
• an established disease or insect pest can be
  nearly impossible to eliminate

11
Insects and Disease

• trees may develop immunity

12
Insect, Fungal, Bacterial

• Dutch Elm Disease - Fungus
• carried by European Elm Bark Beetle

13
Insect, Fungal, Bacterial

• White Pine Blister Rust
• lives part of its life cycle on an alternate host
• wild gooseberries of currants

14
White Pine Blister Rust

• to control the disease, destroy the alternate
  host
• Gypsy Moth - problem with may types of trees

15
Fire Control

• fires are natures way of controlling
  distribution and succession in forests
• prepares some seeds for germination - Jack Pine

16
Fire Control

• fires may add nutrients to the soil
• destroy harmful insects
• provides young shoots and new leaves and other
  vegetation for wildlife

17
Fire Control

• controlled burn
• practiced only with expert advice and under
  supervision

18
Selective harvesting

• trees are thinned out each year in accordance
  with a plan
• remaining trees grow faster, taller and healthier

19
Selective harvesting

• wood is marketed, providing a steady source of
  income
• sustained yield management
