Dr Bill Schaupp is a forest entomologist and an expert on bark beetles, wood borers and post-fire tree mortality. He recently retired after 30+ years with the US Forest Service's Forest Health Protection Program. In this capacity, he provided problem-solving diagnosis and guidance to forest managers from South Dakota to Southern Oregon. Douglas-fir trees have been dying in alarming numbers in Southern Oregon over the past several years. Drought and the flat-headed fir borer have been implicated in the dieback but the situation is more complicated than it appears at first glance. This presentation will review major causes of the recent Douglas-fir mortality and treatment options for landowners. Key questions: What is a hot drought and why is it important? Is the flat-headed fir borer responsible for all the mortality? Does thinning Help? What are your management options? What locations and sites are at the highest risk?
