Sustainable Forestry and Environmental Practices

The video covers sustainable forestry, focusing on practices that minimize ecosystem damage and preserve forests for future generations. It discusses selective and strip cutting, the use of recycled wood, and reforestation. The video also addresses the negative impacts of fire suppression and the benefits of prescribed burns in promoting nutrient cycling and preventing severe forest fires.

What is the primary goal of sustainable forestry?

• To maximize short-term profits

• To clear cut forests efficiently

• To preserve forests for future generations

• To increase soil compaction

Which practice involves cutting only the oldest trees in an area?

• Clear cutting

• Selective cutting

• Machine logging

• Reforestation

How can using human or animal labor benefit sustainable forestry?

• It increases soil compaction

• It reduces soil compaction

• It decreases biodiversity

• It speeds up the logging process

What is a benefit of using recycled wood?

• It increases the demand for new trees

• It reduces the need for logging new trees

• It makes wood more expensive

• It decreases biodiversity

What is reforestation?

• The act of cutting down forests

• The process of soil erosion

• The act of replanting forests in deforested areas

• The use of machine labor in forestry

How does reforestation help the environment?

• It causes soil erosion

• It restores habitats and sequesters carbon

• It increases carbon emissions

• It reduces biodiversity

What is fire suppression?

• Setting controlled fires

• Putting out naturally occurring fires immediately

• Allowing natural fires to burn

• Using recycled wood

What is a prescribed burn?

• A fire that is suppressed immediately

• A small, controlled fire set intentionally

• A natural fire that is allowed to burn

• A method to increase soil compaction

Why are prescribed burns beneficial?

• They increase the buildup of dead biomass

• They cause more severe forest fires

• They promote nutrient cycling and prevent future fires

• They prevent nutrient cycling

What happens when natural fires are suppressed?

• Biodiversity increases

• Soil erosion is reduced

• Nutrient cycling is enhanced

• Dead biomass accumulates, making future fires worse
