Deforestation AP Questions

Which of the following statements best describes the most unsustainable method of clear-cutting forests to harvest timber?

All of the trees in a forest are cut down and removed in one operation.

It has been observed that forest fires can produce up to 40 percent of the mean annual global emissions of which of the following gases?

Carbon dioxide

Which of the following is a commercially used method for harvesting trees and is most likely to lead to a fragmented landscape with serious impacts on biodiversity?

Clear-cutting

Two branches of a river have different sediment loads. Based on the diagram, which of the following most likely led to the differences in the amount of sediment in the two branches of the river?

Deforestation from clear-cutting

Which of the following changes to the local hydrologic cycle will result if large areas of land experienced clear-cutting?

Evaporation of water from the soil will increase.

Industrial logging threatens many forested ecosystems. Which of the following environmental consequences will most likely result from clear-cutting deciduous forests for logging?

More carbon dioxide will be added to the atmosphere and increase anthropogenic climate change.

Which of the following would be the best way to mitigate deforestation?

Replant and protect trees in areas that have been previously cleared.

Coal was surface mined from five sites, labeled 1 through 5, that had originally been covered by forest. Each site was planted with a mix of tree seedlings to reclaim the area to forest. Grass was also seeded over each site to prevent initial erosion and to provide forage. Ten years after planting, information was collected at the five sites and is given in the table below. Select the letter of the row that indicates the site with the most successful forest reclamation.

Row E

Which of the following best achieves the goal of providing wood products for humans while preserving biodiversity?

Selective cutting of large areas of old-growth forest

Which of the following is most likely to occur in a forested region that has been recently clear-cut?

The concentration of nitrates in streams running through the region will increase.

Which of the following hypotheses is best supported by the trends shown in this graph?

The number of acres burned and the number of wildfires have decreased since 1930 because of more large-scale fire suppression interventions such as prescribed burns.

Sustainable use of forests in the United States would likely be encouraged by

cutting small groups of medium- and large- sized trees in uneven-aged forests
