SALEM, Ore. (AP) — Environmental groups and timber companies in Oregon, which have clashed for decades, on Monday unveiled a road map for overhauling forest practice regulations. Gov. Kate Brown called the step “historic.” The agreement came after the two sides quietly held meetings, facilitated by the governor’s office, to try to find common ground, instead of filing competing initiative petitions and lawsuits. Under the new agreement, both sides would complete a stand-down from pursuing changes through the initiative process, related legal actions, and legislative and regulatory proceedings. Both sides also would support immediate legislation to establish helicopter pesticide application buffers, or no-direct application zones, around inhabited dwellings and schools and around streams.
