DRAFT ECONOMIC ANALYSES OF PROPOSED
CRITICAL HABITAT DESIGNATION
IN THE COLORADO RIVER BASIN
FOR THE RAZORBACK SUCKER, HUMPBACK CHUB,
COLORADO SQUAWFLSH, AND BONYTAIL
Volume I
Section 1: Introduction
This volume presents the economic impacts of designating critical habitat for four Colorado
Basin endangered fishes: razorback sucker, bonytail, Colorado squawfish and the humpback
chub. The specifics of this economic analysis -the methods, procedures, and tools used to
determine the economic impacts -can be found in Volume II, where the overall economic
impacts of listing and the designation of critical habitat for the four fishes are also presented.
The Endangered Species Act (Act) provides a means to conserve the ecosystems upon which
endangered and threatened species depend and a program to provide for the conservation of
listed species. The Act provides for the designation of critical habitat necessary for survival
and recovery of endangered species. The designation of critical habitat may impact sectors of
the economy that depend upon resources re-allocated to these endangered species. Therefore,
the Act requires that the economic impacts of critical habitat designations be determined.
The process for designating critical habitat for the four endangered fishes consists of three
major steps. The first step is to complete a biologically based determination of potential
critical habitat azeas. This step yields an inventory of areas that aze needed for the survival
