The Tongass National Forest is the largest in the US, and also one of the biggest reserves of old-growth temperate forest in the world. Quite a bit of its area is protected be the Roadless Rule from timber harvest and development, but the US government is currently considering giving the Tongass an exemption to the Roadless Rule, potentially opening up huge acreage to resource extraction. As part of a team of authors from the Alaska Chapter of The Wildlife Society, Sophie Gilbert helped draft the comment letter that TWS AK recently submitted to Sunny Purdue, the Secretary of the interior.
