President Donald Trump’s administration has set in motion efforts to repeal the Roadless Rule, a 2001 administrative mandate that put 45 million acres of the least developed forest land under protection from logging and construction of roads. As the nation observes the rule’s 25th anniversary, Virginia’s federal lawmakers and advocates are calling for its preservation and say hundreds of thousands of acres of forests could be at stake if it is axed. The federal government has framed the proposed repeal as necessary for forest management against wildfires. …Environmental advocates have said since last summer that repealing the rule will lead to land degradation, sediment pollution, and create risks to clean water sources. It would also open up large swaths of the 400,000 acres of the protected forestland in Virginia to logging and potential new roads.
