More than 400 endangered animal and plant species could face accelerated extinction after the Donald Trump administration’s decision to rescind a rule that has protected old-growth forests for more than two decades. According to a new report from the Center for Biological Diversity, the rollback of the Bill Clinton-era “roadless rule” could put 7.4m acres of endangered-species habitat and nearly 1,800 miles of protected rivers and streams at risk, while opening more than 45m acres of national forests to roads, drilling and logging. The Trump administration moved last week to rescind the 2001 Roadless Area Conservation Rule, citing “outdated restrictions [that] have kept tens of millions of forested acres off-limits to the very treatments that improve forest health and reduce wildfire risk to our communities”.
