California Attorney General Bill Lockyer says he´ll sue to block the federal government´s sweeping plan to manage more than 11 million acres of Sierra Nevada national forests.
Lockyer says the plan violates federal environmental protection laws, and will increase logging, endanger wildlife habitat, harm water quality and weaken grazing restrictions.
Environmental groups say they plan to sue as well, raising similar objections.
But Regional Forester Jack Blackwell says he was driven by a desire to avoid a repeat of the catastrophic wildfires such as devastated Southern California last year.
He says the plan will improve wildlife habitat while reducing fire danger particularly around mountain communities.
