This paper discusses the types of economic benefits that rare and enda
ngered fish provide members of the general public, and a survey method
increasingly used to measure those benefits. The paper also presents
results from recent surveys that have attempted to elicit the economic
values the public holds for rare and endangered fish. These surveys i
ndicate that citizens would pay US$4-$9 per year to increase stream fl
ows and restore habitat of species such as the Colorado squawfish and
$30-$60 per year for increasing populations of Pacific Northwest salmo
n. Validation of market simulations shows that Montana resident angler
s donated on average $2 and nonresident anglers $12 to The Nature Cons
ervancy to increase flows in one river for the Arctic grayling and Yel
lowstone cutthroat trout. A large portion of the dollar values reflect
the benefits citizens derive from simply knowing the abundance of the
se species will be increased and available for future generations. Leg
islators, policy makers, and social scientists should consider these e
conomic factors when debating reauthorization of the Endangered Specie
s Act.
