ESSAY QUESTIONS - Choose two (and only two) of questions 41-43 (10 points each)
41.
Restoration ecology is a new field of study that attempts to use our knowledge of natural
systems to restore them after a disturbance. Describe one example of how restoration ecology has
been put into practice. Clearly indicate in your description those ecological principles that have
been used in the restoration.
42.
Based on the “Yellowstone Fires” article, the “Firestorm” videotape and readings in your
text, describe the ecological role of fire in ecosystems such as the lodgepole forests of Yellowstone
National Park or the Ponderosa pine forests of eastern Oregon. Then, describe a wildfire policy
that would make better use of this knowledge.
43.
The most simple measure of biodiversity is the number of species that occur in an area.
This may not be the most meaningful measure of biodiversity, however. Explain why not all
species are of equal importance with regards to biodiversity.
Note: Your responses to the questions on the videotape “Firestorm” shown in class will
be applied as extra credit on this exam. Please hand in these answers with your exam. (5
