Sustainability and Forest Management Quiz

What is a key factor that can disrupt the sustainability of a biological system?

• Seasonal changes

• Animal migration

• Human consumption of vital resources

• Natural disasters

Why are forests considered sustainable systems?

• They can regrow naturally and support other parts of the ecosystem.

• They never experience natural disasters.

• They do not require any management.

• They are immune to human activities.

What is a consequence of unmanaged forests taking a long time to go through succession stages?

• Immediate regrowth

• Constant timber production

• Reduced biodiversity and slower regeneration

• Increased biodiversity

What is a key advantage of professionally managed forests?

• They never experience natural disasters.

• They can achieve higher levels of sustainability.

• They do not require any human intervention.

• They are immune to climate change.

How do aspen forests regenerate quickly?

• By sprouting new saplings from root suckers

• Through animal assistance

• By human intervention

• Through seed dispersal

What is the benefit of clear-cutting in aspen forests?

• It stops soil erosion.

• It eliminates all wildlife.

• It allows for faster regeneration and timber production.

• It prevents forest fires.

What is a characteristic of mixed hardwood forests?

• Uniform species growth

• Different species with varying growth rates

• No need for management

• Fast regeneration like aspen forests

What is the purpose of selection harvesting in mixed hardwood forests?

• To prevent any tree growth

• To eliminate wildlife

• To select and harvest trees that benefit long-term forest health

• To clear all trees at once

How does selection harvesting affect biodiversity in mixed hardwood forests?

• It reduces biodiversity.

• It eliminates all species except trees.

• It increases biodiversity by providing diverse habitats.

• It has no effect on biodiversity.

What is a potential outcome of not managing mixed hardwood forests?

• Constant wildlife population

• Increased timber production

• A mature climax forest with minimal new growth

• Immediate regrowth
