ForestryObjective 28.01 Describe the impact of forests, their products, and their effect on the economy
Trees provided Native Americans and early settlers with shelter, fuel, medicines, shade and tools.
Today our country is dependent on over 10,000 products provided by forests
Trees have been used for rafts, boats, cabins, sheds, fences, blockades, fuel, warmth, food, clothing, and medicines.
Forests: Past and Present
19.3 million acres of forests in NC Almost 97% of NC forests used for timber 77% privately owned 13% owned by forest industries
NC Forests
Economic value Removal of air and soil pollutants Wildlife habitat Water Quality and Fish Environment Noise Abatement Greenbelts for Moisture Storage Zone Reduction of Wind Erosion, Glare and Reflection Social, Recreational, and Aesthetic Value
Important Roles of Forestry: Overview
Forests provide 300 billion dollars worth of goods
Important Role: Economic Value
Leaves exchange gases removing pollutants Roots circulate nutrients, toxins, and other
pollutants in the soil; removing them
Important Roles: Removal of Pollutants
Just like with Native Americans and early settlers, trees provide shelter and food for Smokey the Bear and all his friends
Forests provide habitat for more species than any other biome in the world
Important Role: Wildlife Habitat
Shade regulates water temperatures Example: trout cannot tolerate warm waters
Help prevent erosion, keeping streams free of pollutants and sediment
Important Roles: Water Quality and Fish Environment
Natural barriers for noise pollution A belt of trees 98 ft wide and 49 ft tall have
proven to reduce highway noise by 6-10 decibels
Important Role: Noise Abatement
A mature oak tree pumps water from the soil and can transpire 100 gallons of water or more into the atmosphere during a hot summer day allowing the soil to store additional runoff
Important Role:Greenbelts- Moisture Storage Zone
A row of trees, with dense foliage, 20 ft high can reduce the speed of wind up to 400 ft
Trees are effective barriers to excessive glare and reflection from surfaces like concrete and glass
Important Role: Reduction of Wind Erosion, Glare, and Reflection
Hiking Nature study Camping Biking Picnicking Hunting/ fishing Photography Bird watching
Important Role:Social, Recreational, and Aesthetic Value
Control Runoff Leaves absorb raindrop impact and roots
prevent soil erosion Dead leaves and limbs enhance soil
development Flood prevention and water flow control Keeps areas cool in summer and warm in
winter (climate influence) Trees serve as nutrient Recyclers
