A developer putting tract housing in a previously pristine area plans numerous small, open space areas where the
original habitat is to remain. As a conservationist, how would you suggest changing the plan, if at all (assume that
canceling the development is not an option)? Why?
What will be an ideal response?
ANSWER: One large preserve would be better than many small preserves, since populations in isolated
habitat patches have a high risk of extinction. Isolated populations often become inbred as
they may not be able to travel to individuals in other habitat patches.
