Management and Use of Forests
Managed Woods proper management results in greater and more uniform growth than when trees are permitted to develop according to natures plan
Management practices planting selected varieties of trees some trees may be used for several purposes
Management rate of growth should be considered most important uses: timber and veneer
Management length of time to maturity faster growing trees have fewer uses
Management Eucalyptus - one of the fastest growing 15 inches in diameter in 40- 50 years
Management Black Walnut, Oak, Hard Maple 100-125 years
Breeding Super Trees select seeds of trees that are fast growing tallest straightest
Breeding Super Trees healthiest raise super trees in nurseries
Controlling Insects and Disease can be variety specific an established disease or insect pest can be nearly impossible to eliminate
Insects and Disease trees may develop immunity
Insect, Fungal, &Bacterial Dutch Elm Disease - Fungus carried by European Elm Bark Beetle
Insect, Fungal, &Bacterial White Pine Blister Rust lives part of its life cycle on an alternate host wild gooseberries or currants
White Pine Blister Rust to control the disease, destroy the alternate host Gypsy Moth - problem with many types of trees
Fire Control fires are natures way of controlling distribution and succession in forests prepares some seeds for germination - Jack Pine
Fire Control fires may add nutrients to the soil destroy harmful insects provides young shoots and new leaves and other vegetation for wildlife
Fire Control controlled burn practiced only with expert advice and under supervision
Selective harvesting trees are thinned out each year in accordance with a plan remaining trees grow faster, taller and healthier
Selective harvesting wood is marketed, providing a steady source of income sustained yield management
Clear Cutting cutting off a sizeable plot of trees during one harvest period.
Clear Cutting Wisdom of this practice is highly debated Essential for commercial reforestation of some species
Clear Cutting Severe soil erosion may occur
Small Land Owners 70% of commercial forest land is held by private owners
Small Land Owners More than 1/2 of saw timber in US is grown on land owned by small land owners or farmers
Small Land Owners Less than 1/5 grown on land owned by large timber companies Doing a better job of forest management
Small Land Owners Conservation is profitable Management involves few cash outlays
Small Land Owners Obtain free advice from: state or national foresters timber company experts
Recreational Uses Multiple use of national forests national parks become more crowded
Recreational Uses Forests provided additional space and scenery Increase in forest visits
Recreational Uses Visits to forests for recreational purposes are increasing at a rate of 10% per year
Wilderness Unsettled, uncultivated natural region
The Wilderness Act Dec. 19, 1964 permanent protection to millions of acres open to public input
Alaska Natl Interest.. Lands Conservation Act Dec. 2, 1980 Increased protected wilderness area in US to 56.6 million acres
Wilderness Additional land under study for wilderness designation Bureau of Land Management
Wilderness Has until 1991 to complete process of wilderness designation
Wilderness met with some opposition
Better use of forest Decrease waste, increase efficiency Particle board paper recycling
Better use of Forest Plastics are being substituted for wood in many products
