Trump Habitat Rollback Takes Effect As Sierra Club and Conservation Partners Sue

A federal rule change under the Trump administration took effect this week, altering how the Endangered Species Act defines "harm" to wildlife. The old definition made clear that destroying or damaging an animal's habitat counts as harm if it ends up killing or injuring a protected species. The new rule removes that language, which critics say makes it easier for companies to move forward with projects that wreck habitat without facing legal consequences under the Act.

The change drew heavy opposition before it took effect. Nearly 220,000 public comments were submitted on the proposal, and 99% opposed it, according to reporting cited in the release. Former leaders of federal wildlife agencies from both parties also spoke out against it. The Sierra Club, working with Earthjustice, filed a lawsuit in July seeking to overturn the rule, arguing it violates both the Endangered Species Act and federal rulemaking law. On September 9, twenty states and Washington, D.C. filed their own separate lawsuits challenging this rule and two related changes to endangered species protections. Separately, a bipartisan group of lawmakers in the House and Senate has introduced measures aimed at reversing the rollback.

This is a policy and legal story rather than one with a direct step for homeowners to take. It does not affect energy-efficiency programs, rebates, or home upgrade incentives. The dispute is playing out in court and in Congress, and its outcome could affect how future development and land-use projects are reviewed near wildlife habitat.
