UW study shows ‘roadless rule’ helps protect drinking water for 25 million people in US

from Think Out Loud

For more than 25 years, the Roadless Area Conservation Rule has helped protect nearly 60 million acres of federal forest lands from logging and road construction. Last year, the Trump administration announced it would end “the roadless rule,” which it claims would allow for “more flexibility” to reduce wildfire risk and for “responsible timber production.” Senate Republicans attached an amendment to the Wildfire Prevention Act last month to repeal the roadless rule that passed out of committee on party lines.     But building new roads to boost timber logging in national forest lands could imperil the quality of drinking water for at least 25 million residents across the U.S., according to a new University of Washington study. That includes residents of Portland, Hood River and other communities who get their drinking water from watersheds in the Mt. Hood National Forest.   The study also found other potential harms from rescinding the roadless rule, including to biodiversity and habitats for species like salmon that spawn in Alaska’s Tongass National Forest and other national forests in the Pacific Northwest. Hunting, fishing and other recreation activities could also be at risk from development of wilderness areas currently protected by the roadless rule.    Michael Dombeck is a co-author of the study and a Professor Emeritus at the University of Wisconsin-Stevens Point. As chief of the U.S. Forest Service from 1997 to 2001, Dombeck helped create the roadless rule and implement it under President Bill Clinton. He joins us for more details.
