Unit 4 Forest Harvesting Methods

What is an ecosystem?

• A place with only plants

• A community of organisms and their environment
  

• A method of cutting trees

• A type of wood product

Clear-cutting involves:

• Cutting only dead trees

•  Removing all trees in an area
  

•  Planting new trees

• Cutting trees in a circle

Selective cutting is different from clear-cutting because it:

• Removes all trees

•  Only removes some trees

• Does not involve cutting any trees
  

• 1. Is only used in urban areas

Sustainable practices in forestry aim to:

• Cut as many trees as possible
  

•  Protect forest health over time

•  Increase deforestation
  

• 1. Use only machinery

Pulpwood is primarily used for:

• Building houses
  

• Making paper
  

• Fuel for fires
  

• 1. Landscaping

Lumber is different from firewood because it is:

• Used for crafts

•  Processed for construction
  

• Left unprocessed
  

• 1. Used only in winter

Deforestation refers to:

• Planting new trees
  

• Removing forests for other land uses

• Maintaining natural habitats
  

•  Protecting wildlife

Reforestation involves:

• Harvesting trees

• Planting trees to restore forests

• Building roads through forests

• Cutting down old trees

Biodiversity is important because it:

• Reduces the number of species

•  Supports a variety of life forms

•  Focuses on one plant species

• Simplifies ecosystems

Coniferous trees are known for:

• Losing their leaves in winter

•  Producing cones and having needles

• Having wide leaves

• Growing only in deserts
