Laramie, WY – The U-S Fish and Wildlife Service has decided not to add the Colorado River cutthroat trout to the threatened or endangered species list. An agency spokeswoman says reviewers did not find sufficient information in the petitions or other sources to justify listing the subspecies. Several groups, including Laramie-based Biodiversity Conservation Alliance, submitted petitions to list the trout in 1999. Those groups have not ruled out legal action over how long it took the agency to make a ruling. The Fish and Wildlife spokeswoman says budget constraints and other higher priorities are reasons for the delay.
