FWS will publish a final rule tomorrow (May 3) downlisting the wood bison.
For those not familiar with the terminology, "downlist" means "to change from endangered to threatened." That's my own definition; it may not be found in any reputable dictionary.
The service said it's changing Bison bison athabascae's designation from E to T because there are more of the big fellows in the wild.
From the FR's pre-publication version:
"This action is based on a review of the best available scientific and commercial data, which indicate that the primary threat that led to population decline, unregulated hunting, is no longer a threat and that recovery actions have led to a substantial increase in the number of herds that have a stable or increasing trend in population size. Critical habitat has not been designated because free-ranging wood bison only occur in Canada and we do not designate critical habitat in foreign countries."
