摘要: Thysell, David R.; Carey, Andrew B. 2000. Effects of forest management on understory and overstory vegetation: a retrospective study. Gen. Tech. Rep. PNW-GTR-488. Portland, OR: U.S. Department Agriculture, Forest Service, Pacific Northwest Research Station. 41 p. Management for wood production through long rotations thinning (MT) biodiversity legacy retention, protection, no subsequent manipulation (ML) are two approaches to managing second-growth forests in the Northwest. We describe how these strategies have affected tree size, density, native exotic vascular plant diversity abundance.
