Many people, including myself, have written about the egregious murder of 890 wolves by the Canadian government "in the name of science" to attempt to recover threatened woodland caribou (please see "Killing 890 Wolves to Learn About Them: Something's Wrong" and "On Killing Wolves: Should Only Trained Ethicists Weigh In?"). The heinous killing didn't work.
The original "research" was published in the Canadian Journal of Zoology (CJZ) by Dave Hervieux, Mark Hebblewhite, Dave Stepnisky, Michelle Bacon, and Stan Boutin in an essay titled "Managing wolves (Canis lupus) to recover threatened woodland caribou (Rangifer tarandus caribou) in Alberta" that presented the outcome of an "experiment" in mass killing in which 890 Canadian wolves suffered and died using aerial gunning, trapping, and poisoning with strychnine. The strychnine also killed other animals who were not part of the study. Minimum "collateral damage" that was deemed acceptable by the researchers and the CJZ included 91 ravens, 36 coyotes, 31 foxes, eight marten, six lynx, four weasels and four fisher. (For more on how wolves are highly stressed when hunted please see "Wolves: Hunting Affects Stress, Reproduction and Sociality.")
