IN DECEMBER 2013, The provincial government of British Columbia, Canada, approved the expansion of a controversial trophy hunt of at-risk grizzly bears. This decision raises doubts about the rigor of wildlife management and government policy in the region. Similar concerns have been raised in the United Kingdom (1) and the United States (“Science behind plan to ease wolf protection is flawed, panel says.” V. Morell, News & Analysis, 14 February, p. 719).
We recently found that between 2001 and 2011, in half of all hunted populations, human-caused death of grizzlies exceeded mortality rates deemed sustainable by government biologists. In addition, failure to properly account for uncertainty in estimates of population sizes, poaching rates, and population growth parameters meant that hunting targets might have been too high(2).
Surprisingly, despite the ensuing media attention, the government reopened hunting in previously overhunted populations, stating, “because we recognize inherent uncertainty in our population and harvest rate estimates, conservative mortality targets are used”(3).
Although the government’s justification borrowed our recent study’s language about uncertainty, their decision ran counter to its conclusions. Moreover, the government came under fire during debate in the provincial legislature (4,5) for claiming in a press release that another recent study (6) confirmed management sustainability, when in fact the paper made no such claims.
Such outcomes reflect a wider problem that often arises when scientific evidence exposes flaws in preferred government policies. Governments can make “science-based” claims without being held to the same standard of transparency and scrutiny expected from scientific researchers. Similar shortcomings were recognized in the proposed delisting of gray wolves from the U.S. Endangered Species Act (Morell’s News & Analysis) and badger culling in Great Britain for disease control (1).
Given the substantial economic and ecological costs of management failure, it is alarming that purported scientifi c management often proceeds without the hallmarks of science—transparency, intelligibility, and rigorous evidence.
We propose that wildlife managers be held to the same level of scrutiny as research scientists through independent oversight similar to the peer-review process. This would incorporate science into management, ensure that the best available evidence is used in management decisions, and improve accountability to the public for whom wildlife are ostensibly managed.

Giving to Raincoast enables you to protect what you love most.
For 25 years, Raincoast has been furthering biodiversity conservation in BC. Thanks to your generous donations, among many other accomplishments, we have been able to end commercial trophy hunting of large carnivores in over 38,000 square kilometers of the Great Bear Rainforest, begin acquiring forest land in order to protect threatened Coastal Douglas-fir ecosystems, aid recovery of endangered Southern Resident killer whales by restoring Chinook salmon habitat, and establish a university research lab dedicated to applied conservation science. Strong partnerships are integral to our success.
Our efforts need to be maintained and advanced, now more than ever. As the biodiversity and climate crises collide, your support allows us to continue to make tangible conservation gains.
Biodiversity protection is the most important gift we can give the next generation. Join us as a Raincoaster today!
