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 nature’s 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 years

7 Management Black Walnut, Oak, Hard Maple 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 nature’s 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 Nat’l 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
