Near-Term Effects of Repeated-Thinning with Riparian Buffers on Headwater Stream Vertebrates and Habitats in Oregon, USA

摘要: We examined the effects of a second-thinning harvest with alternative riparian buffer management approaches on headwater stream habitats and associated vertebrates in western Oregon, USA. Our analyses showed that reaches were generally distinguished primarily by average width depth, along percentage dry reach length, secondarily, volume down wood. In first year post-harvest, we observed no treatment habitat attributes after moderate levels thinning. One two “thin-through” treatments stronger trends for enlarged channels, likely due to disturbances. The salamanders varied among species structure. Densities Plethodon dunni Rhyacotriton increased post-harvest moderate-density thinning no-entry buffers wider streams more pools narrower wood, respectively. However, densities decreased narrowest buffer, 6 m, P. Dicamptodon tenebrosus thin-through buffers. study supports use 15-m or retain sensitive amphibians.
