- ... Mountain hemlock forests in the Oregon Cascades exhibit wave—form dieback resulting from infection by laminated root rot (Phellinus weirii). Although Phellinus remains viable in dead roots after the wave of dieback passes, many regenerating mountain hemlock forests do not become immediately reinfected. We measured at least a doubling of nitrogen availability in the dieback and regrowth zones, and ...

- ... Stand characteristics, dead wood, and soil carbon (C) and nitrogen (N) pools were measured through a wave—regenerated sequence of mountain hemlock death and regrowth created by Phellinus weirii. Stem density increased along the 96—yr regrowth sequence, but was low in the 225—yr—old, mature stand. Total ecosystem C (TEC) dropped upon stand death and did not recover. Net ecosystem production (NEP) w ...
