Section 2 Conservation Biology
Protecting Biodiversity
1. The study of methods for protecting biodiversity is called
conservation biology.
2. How do conservation biologists help the maintain biodiversity?
They develop stratagies
3. Who or what is often the reason why a species is at risk? Human
Activities
4. Why is it difficult for a conservation biologist to develop a
conservation plan? Because the needs of humans often conflict
with the needs of other species.
5. What are 3 reasons the manatees are endangered? Injured or
killed by powerboat propellers, habitat loss due to increased
human population, and water pollution from boats and cities.
Figure 13
6. What are 3 conservation strategies biologists have put in place
to help protect the manatees? Limiting habitat loss, reducing
pollution, and encouraging boaters to obey speed limits.

7. After the American Bald Eagle and the American Alligator were
removed from the endangered species list, what list were they
moved to? Threatened species list
Conservation Biology at Work
8. What are the two goals all conservation plans have? To protect
the species from harm and protect the species’ habitat.
Legal Protection
9. What was the name of the law that was passed in 1973? U.S.
Endangered Species Act
10.
The Endangered Species Act of 1973 makes it illegal to
harm, collect, harass, or disturb the habitat or of any species on
the endangered or threatened species list.
11.
The act also prevents the U.S. government from spending
money on projects that would harm these species or their
habitats.
12.
The goal of the CITES is to control or prevent international
trade.
Habitat Preservation
13.
Conservation biologist often create nature preserves such
as national parks to protect the habitats of endangered species.
14.
What was the name of the United States first national park?
Yellowstone National Park
Wildlife Corridors
15.
What design did conservation biologists develop to help
species that require enormous amounts of land? Wildlife
Corridors
16.
What is the goal of a wildlife corridor? To connect smaller
parks together, so animals can move from one preserve to
another.
Figure 15
17.
What does the wildlife corridor in figure 15 provide the
Florida Panther? A safe passage under a road.
Habitat Restoration
18.
Define habitat restoration: the process of returning a
damaged habitat back to a health condition.
Figure 16
19.
What is the goal of restoring the eelgrass habitat? To help
reserve the shellfish population and fish in Narragansett Bay
Wildlife Management
20.
The sale of hunting licenses provides funds for maintaining
a wildlife area.
Captive Populations
21.
Define a captive population: a population for organisms
that is cared for by humans.
22.
Two negative consequences for keeping a population
captive are it can be expensive and captive animals sometimes
lose their wild behaviors.
Reintroduction Programs
23.
Define a reintroduction program: returning a threatened
species back to its original habitat after the threat has been
removed.
24.
What must occur to ensure a reintroduction program is
successful? The threat must be removed.
Seed Banks
25.
How do seed banks help maintain biodiversity? If any plant
species becomes extinct in the wild, the stored seeds can be
used to reintroduce them to their original habitats.
Relocation
26.
How is relocation different than reintroduction? When you
relocate a species you move it to a new habitat.
