…The mild temperatures through the winter and now into spring have resulted in the invasive emerald ash borer maturing faster and emerging weeks earlier than usual, the Oregon Department of Forestry says. Wyatt Williams, an invasive species specialist with the department, confirmed he found one in early May in King City in southeast Washington County, a news release states. …So far there’s no cure for a tree infested with the bugs – they’re a death sentence, the Extension Service says. It can take up to six years for an infested tree to die. …Ash borers normally start emerging from inside tree trunks in early June and into July, Oregon forestry officials say. But that’s changing along with the climate. This past winter was tied with 1934 as the warmest on record in western Oregon, followed by record-breaking or near record-breaking high temperatures this spring, the state said in a statement.
