Oregon’s forestry department has proposed a flexible approach to managing state-owned forests west of the Cascades over the next 70 years. Staff say it will allow them to adapt as scientific understanding evolves — and as the climate changes. But environmental groups say the department has drafted a plan that’s too vague. They would like to see more focus on saving the mature and complex forests. Members of the public can submit their input. …This forest management plan is meant to accompany the Western State Habitat Conservation Plan — a 70-year agreement with the federal government that ensures state logging projects comply with the Endangered Species Act. That plan, often referred to as the HCP, outlines conservation measures the state will take to offset the environmental harms of logging. It’s awaiting federal approval, expect edby the end of March. If approved, it would prohibit logging on about 43% of western state forests.
