Strategic planning for instream flow restoration: a case study of potential climate change impacts in the central Columbia River basin
Year: 2012
We provide a case study prioritizing instream flow restoration activities by sub-basin according to the habitat needs of Endangered Species Act (ESA)-listed salmonids relative to climate change in the central Columbia River basin in Washington State (USA). The objective is to employ scenario analysis to inform and improve existing instream flow restoration projects. We assess the sensitivity of late summer (July, August, and September) flows to the following scenario simulations singly or in combination: climate change, changes in the quantity of water used for irrigation and possible changes…

Identifying policy target groups with qualitative and quantitative methods: the case of wildfire risk on nonindustrial private forest lands
Year: 2012
This article identifies four types of nonindustrial private forest owners with different motivations for managing forestland in Oregon's fire-prone areas and different suitabilities for wildfire risk reduction policy approaches: “Commodity managers” (27% of owners, 40% of ownership area) are motivated to harvest and sell timber for income, to protect assets, and to perpetuate a family legacy of forestry. Policies that reinvigorate markets for small-diameter wood products could motivate these owners with markets that provide economic justification for reducing fuel. “Amenity managers” (21% of…

Wildfire severity mediates fluxes of plant material and terrestrial invertebrates to mountain streams
Year: 2012
Wildfire effects upon riparian plant community structure, composition, and distribution may strongly influence the dynamic relationships between riparian vegetation and stream ecosystems. However, few studies have examined the influence of fire on these processes. To that end, we compared the quantity and composition of allochthonous inputs of plant material and terrestrial invertebrates among stream tributaries characterized by various degrees of burn severity 5 years post-fire in the Frank Church Wilderness of central Idaho, USA. The magnitude of inputs of coniferous leaf litter to unburned…
