Chapter 11: Forestry and Resource Management
Resource Management
Maximum sustainable yield, ecosystem-based management, and adaptive management are tree approaches to what?
Not letting a fire occur, it can result in a smaller fires that can turn into bigger and more dangerous fives.
Describe fire suppression and what it can result in.
Carefully controlled burning is set up intentionally by people and helps to reduce fuel buildup to restore ecosystems. Humans cause prescribed burns.
Describe prescribed burns and who they are caused by.
All trees in an area are cut down, results in even-aged regrowth
Describe the timber harvesting method clear-cutting.
requires plans for national forests that follow multiple use and maximum sustainable yield
Explain the National Forest Management Act.
It is more dangerous for loggers, it's more expensive
Explain the disadvantages of the selection system method of harvesting.
Clearing of a forest; tropical-massive loss of biodiversity arid-loss of soil productivity, leads to desertification
Explain what deforestation is. What does it lead to in both arid and tropical regions?
The roots hold the soil in place and pants slow runoff that would cause erosion.
How do forest plants prevent soil erosion?
produced sustainably
If a wood product is certified by the Forest Stewardship Council, how was it produced?
Trees in the rain forest are often cleared by burning, which adds carbon dioxide to the atmosphere.
In what way does deforestation of tropical rain forests affect global warming?
It provides timber, it's a source of food, and provide raw materials for medicine
In what ways do forests provide economic values?
An even-aged monoculture, most logging is done on private land
What does private logging operations produce?
promote salvage logging and prescribed burns
What is the main goal of the Healthy Forests Restoration Act?
to water crops
What is the most of Earth's fresh water used for?
Selection system
What method of timber harvesting produces a future forest that most closely resembles the original forest in terms of biodiversity
It is harvested sustainably if the amount of replacement is equal or greater than the amount harvested.
When is a renewable resource considered to sustainably harvested?
Ecosystem-based management
Which approach to resource management aims to harvest resources in ways that minimize impact on the ecosystem and processes that provide the resource?
Clear cutting; more tees can be cut down in a given amount of time
Which method of timber harvesting is likely to lead to a greater amount of deforestation in an area? Why?
Selection system
Which method of timber harvesting leads to the greatest uneven-aged stands of regrowth?
An uneven-aged forest
Which type of forest most likely contains the greatest variety of habitats
soil, freshwater, wild animals, and timber
name examples of renewable resources.
