Five Threat (Listing) Factors: relative importance
The U.S. Endangered Species Act requires that a listed species be threatened by one or more of five factors. While a binary "affects / doesn't affect" is somewhat useful, it is much more useful to describe the relative importance of each threat: resource allocation decisions may be greatly improved if resources are allocated in proportion to the threat.
