Mapping Temporal Dynamics in a Forest Stream Network—Implications for Riparian Forest Management
This study focuses on avoiding negative effects on surface waters using new techniques for identifying wet areas near surface waters. This would aid planning and designing of forest buffer zones and off-road forestry traffic. The temporal variability in the geographical distribution of the stream network renders this type of planning difficult. A field study was performed in the 68 km2 Krycklan...
متن کاملLow thermal tolerances of stream amphibians in the Pacific Northwest: Implications for riparian and forest management
Temperature has a profound effect on survival and ecology of amphibians. In the Pacific Northwest, timber harvest is known to increase peak stream temperatures to 24◦C or higher, which has potential to negatively impact cold-water stream amphibians. I determined the Critical Thermal Maxima (CTmax) for two salamanders that are endemic to the Pacific Northwest. Rhyacotriton variegatus larvae accl...
متن کاملEffects of Salmon-Derived Nitrogen on Riparian Forest Growth and Implications for Stream Productivity
Anadromous Pacific salmon (Oncorhynchus spp.) transport marine-derived nitrogen (MDN) to the rivers in which they reproduce. Isotopic analyses indicate that trees and shrubs near spawning streams derive -22-2492 of their foliar nitrogen (N) from spawning salmon. As a consequence of this nutrient subsidy, growth rates are significantly increased in Sitka spruce (Picea sitchensis) near spawning s...
متن کاملHillslope hydrologic connectivity controls riparian groundwater turnover: Implications of catchment structure for riparian buffering and stream water sources
[1] Hydrologic connectivity between catchment upland and near stream areas is essential for the transmission of water, solutes, and nutrients to streams. However, our current understanding of the role of riparian zones in mediating landscape hydrologic connectivity and the catchment scale export of water and solutes is limited. We tested the relationship between the duration of hillslope‐ripari...
متن کاملGeomorphic and Riparian Influences on the Distribution and Abundance of Salmonids in a Cascade Mountain Stream
2 Graduate Research Assistant and Associate Professor of Fisheries, respectively, Department of Fisheries and Wildlife, Oregon State University, Corvallis, OR, 97331, USA. Abstract: Abundance of resident cutthroat (Salmo clarki) and rainbow (Salmo gairdneri) trout was generally 1.5 to 3.5 times greater in unconstrained reaches than in constrained reaches of Lookout Creek, a fourth-order tributa...
