Management and Use of Forests

1
Management and Use of Forests
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 or currants

14
White Pine Blister Rust

• to control the disease, destroy the alternate
  host
• Gypsy Moth - problem with many 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

20
Clear Cutting

• cutting off a sizeable plot of trees during one
  harvest period.

21
Clear Cutting

• Wisdom of this practice is highly debated
• Essential for commercial reforestation of
  some species

22
Clear Cutting

• Severe soil erosion may occur

23
Small Land Owners

• 70 of commercial forest land is held by private
  owners

24
Small Land Owners

• More than 1/2 of saw timber in US is grown on
  land owned by small land owners or farmers

25
Small Land Owners

• Less than 1/5 grown on land owned by large timber
  companies
• Doing a better job of forest management

26
Small Land Owners

• Conservation is profitable
• Management involves few cash outlays

27
Small Land Owners

• Obtain free advice from
• state or national foresters
• timber company experts

28
Recreational Uses

• Multiple use of national forests
• national parks become more crowded

29
Recreational Uses

• Forests provided additional space and scenery
• Increase in forest visits

30
Recreational Uses

• Visits to forests for recreational purposes are
  increasing at a rate of 10 per year

31
Wilderness

• Unsettled, uncultivated natural region

32
The Wilderness Act

• Dec. 19, 1964
• permanent protection to millions of acres
• open to public input

33
Alaska Natl Interest..

• Lands Conservation Act
• Dec. 2, 1980
• Increased protected wilderness area in US
  to 56.6 million acres

34
Wilderness

• Additional land under study for wilderness
  designation
• Bureau of Land Management

35
Wilderness

• Has until 1991 to complete process of wilderness
  designation

36
Wilderness

• met with some opposition

37
Better use of forest

• Decrease waste, increase efficiency
• Particle board
• paper recycling

38
Better use of Forest

• Plastics are being substituted for wood in many
  products
