It’s supposed to prevent them according to the advocates.
But Section 3, Part 1, Paragraph c in yesterday’s solicitation for fertility control services says the method of capture will be with the use of [helicopter] drive and/or bait trapping in accordance with the standards of the Comprehensive Animal Welfare Program.
The advocates oppose the use of helicopters, but perhaps they can be accommodated in the early stages of the project until the herds are small enough to stalk the remaining animals on the range and shoot them with darts as taught in Billings.
The advocates refer to sterilized mares as “self-boosting.”
The CAWP and other supporting documents can be found at the solicitation page.
