• Stayed the same

• Fluctuated

Multiple Choice

Historically, the crab population in the Chesapeake Bay has __________.

• Stayed the same

• Fluctuated

Multiple Choice

True or False: Since 2012, the crab population has seen an overall increase.

• True

• False

Multiple Choice

Which of the following could affect the blue crab population in the Chesapeake Bay?

• Oxygen and salinity (salt) levels

• Water temperature

• Commercial and recreational harvest (catching)

• Available habitat and predators

• All of the above

Multiple Choice

Submerged aquatic vegetation (SAV) has __________ over time.

• Increased

• Decreased

• Fluctuated

Multiple Choice

Since 2012, the total acreage of SAV has __________.

• Increased

• Decreased

• Stayed the same

Multiple Choice

Total wetland acreage has __________ since 2009.

• Not changed

• Increased

• Decreased

Multiple Choice

Total forest buffers have __________ since 1996.

• Increased

• Decreased

• Fluctuated

Multiple Choice

Based on the information seen in the previous slides, choose the statement that is most likely correct.

• Changes to land-based ecosystems probably don’t affect blue crabs.

• Conditions in the Chesapeake Bay are relatively stable year-to-year.

• The rate of forest buffer restoration has been consistent from 1996 to 2016.

• Increases in SAV acreage from 2007 to 2017 may be related to the increases in blue crab population during the same period.

Multiple Choice

True or False: Increases in wetlands, forest buffers, and SAV will result in increases in the blue crab population and other fisheries over time.

• True

• False

LC3 Assessment Information Summary

• The Conowingo Dam is a major source of electricity for parts of Maryland. It is a renewable and clean energy source.

• The American Eel is an important for the Chesapeake Bay ecosystem because it is a major food source for many native species. In other countries this eel is highly sought after, and there is a commercial harvest for the eel in the Chesapeake Bay.

• The eel is threatened by this harvesting and habitat destruction/fragmentation caused by the Conowingo Dam. Some people call for removal of the dam to improve the American Eel populations.

Multiple Choice

True or False: The Conowingo Dam is a source of clean and renewable energy for Maryland and has no negative impacts.

• True

• False

Multiple Choice

True or False: Removal of the Conowingo Dam could provided a solution to problems facing the American Eel, but doing so would result in the loss of a major source of energy for Maryland.

• True

• False
