Land Use - Chapter 10

Tropical forests in the Amazon Basin and other South American countries are primarily being cleared or burned for

• cattle grazing and soybean plantations
• biodiesel  for motor vehicles
• coffee and spice plantations
• oil palm and paper pulp plantations

Which of the following type of tree harvesting is the most detrimental to the environment?

• Strip Cutting
• Selective Cutting
• Clear Cutting 
• Partial Harvest

Which of the following is NOT an ecosystem service provided by forests?

• Provide habitat
• Aid in nutrient cycling
• Sequester Carbon
• Recreational opportunities

All of the following are ecological benefits of surface fires EXCEPT

• Aid in seed dispersal in certain species, such as lodgepole pines
• Return key nutrients back in to the soil
• Stimulate germination in some trees
• Destroys the wildlife and vegetation in an area

Which of the following contains 1-2 tree species that are clear-cut & replanted at regular intervals?

• Old Growth Forest
• Tree Plantation
• Secondary-growth forest
• Tropical Rainforest

Unfenced grasslands in tropical and temperate climates that supply forage for grazing animals are called

• rangeland
• pastures
• savannah
• steppes

Most of the deforestation occurring today is happening where?

• Indonesia
• Latin America
• Africa
• All of these

Scientists estimate that if logging and conversion of forests to agricultural land continues, forest cover in the Amazon Basin will be reduced to only 20% of its original size by the end of this year. The loss of forested land would most likely

• increase the water vapor in the atmosphere due to increased transpiration rates
• decrease the local regional flooding that occurs
• increase the total amount of atmospheric carbon dioxide
• decrease the amount of total atmospheric nitrogen

Which of the following is a threat to forest ecosystems? 

• climate change
• unsustainable logging
• invasive species 
• All of these

The largest area of old -growth forest in the world is located in 

• the United States
• Russia
• Costa Rica
• Mexico
