5.2 Clearcutting

• What is the primary goal of clearcutting in forestry practices?

  Even-aged tree growth
• Clearcutting promotes even-aged tree growth by replanting cleared land with a single type of tree
• Clearcutting can lead to increased topsoil loss and river sedimentation.
• What happens to wildlife habitat when clearcutting is used?

  Destruction of ecosystems
• Match the environmental impact with its effect:

  Soil Erosion ↔️ Topsoil loss

  Habitat Loss ↔️ Elimination of wildlife

  Decreased Biodiversity ↔️ Uniform replanting

  Water Quality Degradation ↔️ Sediment and nutrient runoff
• What are the main economic benefits of clearcutting?

  Efficient harvesting and reduced labor costs
• Efficient harvesting in clearcutting simplifies the logging process by removing all trees
• Reduced labor costs in clearcutting are due to quicker clearing and replanting.
• Which industries benefit the most from the economic advantages of clearcutting?

  Lumber, paper, construction
• What is the primary environmental consequence of clearcutting for timber harvesting?

  Soil erosion and habitat loss
• Order the steps involved in the environmental impacts of clearcutting:

  1️⃣ Removal of tree cover

  2️⃣ Exposure of soil to erosion

  3️⃣ Topsoil loss and sedimentation

  4️⃣ Destruction of ecosystems
• Soil erosion from clearcutting leads to the loss of topsoil and increased sedimentation
• Clearcutting reduces the need for selective cutting, making timber harvesting more efficient.
• What type of timber yield does clearcutting promote in a uniform area?

  Higher timber production
• What are the three main economic benefits of clearcutting mentioned in the study material?

  Efficient harvesting, reduced labor costs, increased timber yield
• Clearcutting simplifies logging by reducing the need for selective cutting
• Clearcutting lowers labor costs due to faster clearing and uniform replanting.
• How does clearcutting increase timber yield?

  Promotes rapid growth of chosen species
• Clearcutting is equally beneficial for all industries that rely on timber.

  False
• What is the primary effect of clearcutting on soil erosion?

  Exposes soil to wind and rain
• Clearcutting leads to habitat loss by destroying diverse ecosystems
• Why does clearcutting reduce biodiversity?

  Uniform replanting with a single species
• Water quality degradation is a consequence of increased sediment and nutrient runoff caused by clearcutting.
• Match the sustainable forestry practice with its description:

  Selective Cutting ↔️ Harvests mature trees while retaining forest structure

  Agroforestry ↔️ Integrates trees with crops or livestock

  Reforestation ↔️ Replants cleared areas with diverse tree species
• Sustainable forestry practices ensure forests remain healthy and productive for future generations
• What is the primary purpose of clearcutting in forestry management?

  Economic benefits
• Clearcutting provides long-term economic gains for forestry industries.

  False
• What does soil erosion caused by clearcutting lead to?

  Topsoil loss and sedimentation
• Habitat loss from clearcutting reduces wildlife populations.
• Uniform replanting with a single tree species reduces biodiversity
• Match the environmental impact of clearcutting with its effect:

  Soil Erosion ↔️ Topsoil loss and sedimentation

  Habitat Loss ↔️ Displacement of wildlife

  Decreased Biodiversity ↔️ Uniform replanting of trees
• Water quality degradation is a consequence of clearcutting.
• Clearcutting has significant negative consequences on the environment
• What are the three economic benefits of clearcutting?

  Efficient harvesting, reduced labor costs, increased timber yield
• Efficient harvesting in clearcutting simplifies logging and reduces the need for selective cutting.
• Reduced labor costs in clearcutting are due to faster clearing and uniform replanting
• Which industries benefit from the increased timber yield of clearcutting?

  Lumber, paper
• Nutrient runoff from clearcutting degrades water quality
• What are three sustainable forestry practices that contrast with clearcutting?

  Selective cutting, agroforestry, reforestation
• Match the sustainable forestry practice with its benefit:

  Selective Cutting ↔️ Maintains habitat and reduces soil erosion

  Agroforestry ↔️ Enhances soil fertility and diversifies income

  Reforestation ↔️ Restores ecosystems and sequesters carbon
