Concerns About Mammal Predator Killing Programs: Scientific Evidence and Due Diligence

Posted on May 2, 2018

Author by Gilbert PROULX CWBM 7 (1): 56–66 Abstract The implementation of mammal predator killing programs is highly controversial and deserves discussion within the scientific community. In this opinion paper, I use specific examples to discuss the whys and hows of programs aimed at: 1) ensuring human safety and health; 2) addressing concerns of interest groups; and 3) safeguarding native and endangered species. Successful programs share some commonalities: they focus on the main factor that is responsible for the problematic situation and on culprit animals, and they are developed with an...

Author by Nicole M. MacDONALD, and Erica NOL Correspondence: Environmental and Life Sciences, Trent University, Peterborough, Ontario, K9L 0G2, Canada.  Email: nicolemacdonald22@gmail.com Abstract We investigated the impact of beef cattle (Bos taurus) farm management, including rotationally grazed pastures and managed hayfields, on the reproductive success of bobolink (Dolichonyx oryzivorus) in eastern Ontario, Canada. Bobolinks nesting in fields grazed by cattle or cut for hay before 1 July had significantly lower reproductive success than those nesting in untouched fields. Bobolinks did...
