The introduction to this chapter (pages 1003 to 1004 in your textbook) stated that its goal was to introduce the information needed to help preserve biodiversity. To test whether this goal was achieved, think of a species that is endangered in the region surrounding your college or university. Then answer the following questions: What are the primary factors responsible for the species' decline? Are these factors similar to or different from the factors responsible for concern about diversity in tropical rain forests? If you were a conservation manager, what steps would you take to ensure that the remaining population did not become inbred? How would you go about designing a regional conservation plan for this species and for other organisms that occupy the same habitat?
