Canadian conservationists and wildlife experts are expressing concern following the Trump administration’s recent decision to weaken habitat protections for endangered species in July. The U.S. Department of the Interior announced on July 10 that it would be revoking a longstanding definition of “harm” under the Endangered Species Act (ESA).
Various wildlife and environmental groups have strongly criticized the move, stating that it disregards the ecosystems crucial to the survival of vulnerable species amidst ongoing biodiversity decline and industrial activities. In response, nearly a dozen organizations have filed a lawsuit in U.S. District Court to challenge the repeal, set to take effect on September 14.
According to Canadian experts interviewed by CBC News, the alteration could pose a threat to animals that traverse both U.S. and Canadian territories, particularly those species that migrate across borders to seek food, reproduce, or escape harsh Canadian winters. These species include migratory birds, northern spotted owls, grizzly bears, and southern resident killer whales, as highlighted by Torrance Coste, the associate director of the Wilderness Committee based in British Columbia.
The concern is amplified by the fact that certain species like the southern resident killer whales do not recognize international boundaries in their habitat as they move between U.S. and Canadian waters seamlessly. Coste emphasized the potential impact of the U.S. lowering the threshold for defining harm to endangered species, underscoring the significance of the issue.
The Trump administration defended its decision to rescind the definition of “harm” under the Endangered Species Act, asserting that it aims to put an end to what it calls “years of federal overreach.” While reaffirming that ESA protections will persist, the administration argued that the change would alleviate burdens on landowners and communities.
The reinterpretation of “harm” by U.S. agencies has been a longstanding practice, encompassing activities that result in significant habitat alterations or degradation leading to harm or injury to wildlife. However, the recent repeal has drawn criticism from organizations like the Center for Biological Diversity, with its endangered species co-director, Noah Greenwald, stating that it fundamentally undermines decades of species protection efforts.
Habitat destruction remains a primary driver of biodiversity loss globally, making it exceedingly challenging to safeguard animals that rely on specific ecosystems. Dennis Murray, a wildlife conservation expert and biology professor at Trent University, highlighted the importance of preserving entire home ranges rather than isolated habitat areas for species like monarch butterflies, which depend on specific plants for their survival.
While the concerns primarily focus on U.S. environmental policies, there are also warnings that Canada may be heading in a similar direction. Prime Minister Mark Carney’s government is exploring measures to expedite permitting for major infrastructure projects, potentially affecting species at risk. This prospect has raised alarms among experts, who stress the importance of strengthening wildlife protection laws in both countries instead of weakening them.
Authorities in Canada have emphasized their commitment to conservation efforts, citing a substantial federal nature strategy announced earlier in the year. Additionally, collaborations with the U.S. under a trilateral committee on wildlife and ecosystem conservation in North America underscore the shared dedication to protecting nature and species across borders.
