9.4 Managing forests Flashcards
1
Q
Reasons for the need for the
sustainable management of forests
A
- forests act as carbon sinks and mature forests act as carbon stores
- role in water cycle
- prevention of soil erosion
- biodiversity as a genetic resource
- food, medicine and industrial raw materials
- ecotourism
2
Q
Growing Forests as Carbon Sinks and Mature Forests as Carbon Stores
A
- Young, growing forests absorb carbon dioxide (CO₂) from the atmosphere, acting as carbon sinks.
- Mature forests store vast amounts of carbon in their biomass and soil, preventing it from entering the atmosphere.
Importance: Helps combat climate change by reducing greenhouse gas levels.
3
Q
role in water cycle
A
- Forests add water to the atmosphere during transpiration, leading to formation of clouds, eventually releasing it by precipitation.
- Importance: Ensures water availability for ecosystems and human use while preventing droughts and floods.
- During deforestation, this process is reduced and local droughts are caused in the area.
4
Q
prevention of soil erosion
A
- By intercepting rain, forests reduce heavy rainfall on the forest floor.
- Debris, such as tree leaves on the floor of the forest, slows run-off.
- Roots of trees hold soil in place.
5
Q
Provision of Food, Medicine, and Industrial Raw Materials
A
Forests supply fruits, nuts, and medicinal plants, as well as timber, rubber, and other industrial resources.
6
Q
Ecotourism
A
- Forests attract tourists seeking nature experiences, providing income for local communities and incentivizing conservation.
- Visitors travel with the main aim of appreciating its natural beauty.
