No “Biobullets” for Yellowstone Bison
(WEST YELLOWSTONE, MT) – Yellowstone National Park administrators have nixed a plan to shoot bison with absorbable, vaccine-laced biobullets to prevent the spread of brucellosis. Officials say the $300,000 annual price tag and mixed opinions about the effectiveness of the vaccine don’t justify the cost. That means the park will continue to allow periodic roundups of bison who wander outside the park–most of which end up being slaughtered. Around half of Yellowstone’s 4,600-strong bison herd are infected with the disease, which causes pregnant animals to prematurely abort their calves.
