Refer to this news release dated 06/20/18. Pastures must be able to accommodate at least 100 animals and must be located in Colorado, Kansas, Montana, Oklahoma or Wyoming. They must provide a free-roaming environment and allow for public visitation and viewing.
The action is justified by the number of wild horses and burros on western rangelands vis-à-vis ‘other legally mandated land uses’ [such as, ahem, cough-cough, livestock grazing].
Bidders will be expected to care for the animals for periods of up to ten years. Proposals are due 07/10/18.
