The best example of selective cutting is;

• Loggers cut small groups of intermediate or mature trees, resulting in less erosion and loss of nutrients on the hillside.

• Loggers cut all of the trees in an area, resulting in a loss of nutrients in the soil and sediment gathering in the stream downslope.

• Loggers cut a thin strip of trees along a hillside, the forests naturally regenerates, and loggers then cut a thin strip of trees next to the regenerated area.

• In a managed area forest containing one or two species of trees, loggers clear cut one section, then clear-cut it again when the trees have reached a certain size.

• Loggers cut only the trees they can reach easily from exsisting access roads.

All of the following would result in an area that would result in an area thast was recently clear-cut EXCEPT;

• An increase in the likelihood of mudslides on sloped, denuded land.

• A loss of soil nutrients, because of the increase in wind and water erosion.

• An increase in erosion, because water flows faster on denuded slopes.

• An increase in biodiversity, because cleared land is more inviting to a variety of new species.

• An increase in water pollution as sediment flows into streams.

Which of the following best decscribes a second-growth forest?

• Strands of trees resulting from natural succession on a disturbes site.

• Forest that has not been seriously disturbed for at least 200 years.

• Strands of trees of uniform age and species that have been planted by humans.

• Forest only found in rural areas in canada, Brazil, and Russia.

• Forest only found in rural areas and density.

Fires that burn away flammable ground material and help prevent more destructive fires are called;

• Crown fires

• Ground fires

• Surface fires

• High Intensity fires

• Low-intensity fires

One effect of our overgrazing of the natural range lands is;

• Increased biodiversity because of the increase in plants cattle will not eat, such as mesquite, sagebrush, and cactus, as well as the insects and mammals these plants attract.

• Decreased solar power because soil is compacted and can no longer support power cells.

• Inversion of the human population pyramid as less vegetation is available and ranchers must sell their cattle because of the lack of rangeland available to them.

• Soil erosion, because cattle damage the grass roots and the grass can no longer regrow.

• Increased soil porosity, because cattle are not present to compact the land they occupy.

Which of the follwing U.S federal lands is the most restricted in terms of public and corporate use, such as grazing, mining, and sports hunting?

• Wilderness areas

• National wildlife refuges (USWS)

• The National Forest System (USFS)

• National Resource Lands (BLM)

• National recreational Lands (BLM)

A farmer in a developing nation will try to plant the maximum amount of crops on his land. This farmer would most likely use which method of tree-cutting.

• Cut a strip of trees, but then cut another strip of trees when the first ones grow back, preventing mass erosion and protecting his crops.

• Cut most of the trees, but leave those that produce seeds so new trees can grow back.

• Remove all of the mature trees, leaving the younger ones to provide for shade for crops that need it in order to survive.

• Cut all of the trees in the area, regardless of the resulting nutrient loss and erosion.

• Remove only small groups of older trees so more nutrients would be available for his crops.
