Canadian conservationists and wildlife experts express concern following the decision by the U.S. President Donald Trump’s administration to relax habitat protections for endangered species in July. The U.S. Department of the Interior announced on July 10 that it was revoking a long-standing definition of “harm” under the Endangered Species Act (ESA).
Various wildlife and environmental organizations swiftly criticized the move, stating that it disregards the critical ecosystems on which vulnerable species rely amidst widespread biodiversity decline and industrial pressures. Nearly a dozen groups have initiated a lawsuit in U.S. District Court to challenge the repeal, which is scheduled to come into effect on September 14.
According to Canadian experts interviewed by CBC News, this alteration could endanger animals that traverse both countries’ borders, such as migratory birds, northern spotted owls, grizzly bears, and southern resident killer whales, also known as orcas. Torrance Coste, the associate director of the Wilderness Committee advocacy group based in British Columbia, emphasized the potential impact on orcas, noting their seamless movement between U.S. and Canadian waters.
The Trump administration defended its decision to rescind the “harm” definition under the ESA, asserting that it would eliminate federal overreach while preserving protections for endangered species and alleviating burdens on landowners and communities. This move contradicts decades of interpreting “harm” to include activities that result in significant habitat modifications or degradation, a definition upheld by the U.S. Supreme Court in the mid-1990s.
Critics, including Noah Greenwald from the Center for Biological Diversity, one of the litigating groups, argue that this repeal fundamentally undermines species protection efforts over the past half-century. They caution that habitat destruction, the primary driver of global biodiversity loss, could have far-reaching consequences, affecting wildlife populations in Canada when habitats deteriorate in the U.S.
Dennis Murray, a wildlife conservation expert from Trent University, emphasized the challenges of protecting animals that rely on habitats where protections have been weakened. He highlighted the importance of safeguarding entire home ranges for species like monarch butterflies, which depend on specific plants for survival.
While Canadian conservationists are particularly troubled by Trump’s environmental policies, concerns also linger about Canada’s direction. The government, led by Prime Minister Mark Carney, aims to expedite permitting for major infrastructure projects amid economic pressures. A recent discussion paper proposed legislative changes that could grant limited powers to exempt projects from species at risk assessments, sparking alarm among environmental advocates.
In response to these concerns, both countries are urged to enhance species protection laws rather than weaken them, as emphasized by Torrance Coste. Efforts to strike a balance between environmental conservation and economic development remain crucial for the future protection of wildlife in North America.
