JUNEAU, Alaska — A federal agency said Wednesday it is reinstating restrictions on road-building and logging on the country’s largest national forest in southeast Alaska, the latest move in a long-running fight over the Tongass National Forest. The U.S. Department of Agriculture in late 2021 announced that it was beginning the process of repealing a Trump administration-era decision that exempted the Tongass from the so-called roadless rule. The agency said it had finalized that plan. The new rule will take effect once it is published in the Federal Register, which is expected to happen Friday, said Larry Moore. …Roadless areas account for about one-third of all U.S. national forest system lands. But Alaska political leaders have long sought an exemption to the roadless rule for the Tongass, seeing the restrictions as burdensome and limiting economic opportunities.
