11.2 Forests and Their Resources

Front

What is the selection system in forestry?

Back

A method of harvesting trees that allows for the selective removal of certain trees while preserving the overall forest structure.

Front

What is clear-cutting?

Back

A logging method that involves removing all trees in a designated area, often leading to significant environmental impact.

Front

What are the environmental impacts of clear-cutting?

Back

Clear-cutting can lead to soil erosion, loss of habitat, and displacement or destruction of local communities.

Front

What is the seed-tree approach in forestry?

Back

A method where a few seed-producing trees are left standing to regenerate the forest after logging.

Front

What is the shelterwood approach?

Back

A forestry method that involves removing trees in phases to allow for natural regeneration under the shelter of remaining trees.

Front

What is the difference between timber harvesting and deforestation?

Back

Timber harvesting is the process of cutting down trees for wood while maintaining forest cover, whereas deforestation involves clearing forests for other land uses.

Front

What is a cost associated with the seed-tree and shelterwood approaches?

Back

These methods can lead to mostly even-aged regrowth, which may reduce biodiversity.

Front

What is one benefit of the selection system?

Back

It results in less overall environmental damage compared to clear-cutting.

Front

What is the impact of deforestation on biodiversity?

Back

Deforestation typically leads to a decrease in biodiversity as habitats are destroyed.

Front

What are the economic impacts of clear-cutting on local communities?

Back

Clear-cutting can lead to displacement or destruction of local communities, affecting their livelihoods.
