Conservation and Management of Wild Species

Short
Answer

1. Why are small
populations more threatened with extinction?

2.  What should the two main aims of conservation
be?  Explain your reasoning.

3.  If an area of an uncommon type of vegetation
is reduced to small separated patches, how will this affect the population of
animals living there?  Would there be a
difference in the reaction of the animals if that patch was a more common type
of vegetation?  How?

4.  What features of animal life control the
amount of space they need to survive? 
Describe two.  Why can an animal
the size of a raccoon survive so well in a city?  Do humans change the amount of space animals
need to survive?  How?

5.  Some ecologists think that habitat corridors
are very important and some think that animals can function just as well without
them.  As usual, both of these opinions
are likely true.  Explain how both can be
true at the same time.

6.  Can humans alter conditions in such a way as
to promote high diversity?  How would you
achieve this aim?

7.  Describe the creation from the beginning
through the present of the Shenandoah National Park.  Be complete.

8. Describe how the
Endangered Species Act works and what is contained within the document.
