Climate change impacts on forests, including drought and wildfire, are of increasing concern to managers, conservationists, researchers, and culture bearers in the Pacific Northwest. Warmer temperatures exacerbate forest stress by accelerating evaporation and drying-out of the land surface and vegetation. These hotter drought conditions have been implicated in recent tree mortality events regionally and across the globe. Managers need science-based tools to assess risks posed by droughts, heat waves, and other climate-induced stressors, as well as practical solutions for adapting current management practices. The realities of climate change have spurred interest in tailoring silvicultural practices to increase forest...

Climate change in the Northwest is causing warmer summer stream flows that can decimate cold-water species like salmon. This problem can be worsened in shoreline embayments or small streams that receive direct stormwater runoff from warm city environments. There has been little assessment, however, at the source: how urban warming – or cooling, such as by tree shade – affects curbside runoff temperatures from streets to storm drains. This research found that warm summer runoff might be cooled at its source via small adaptations in urban forestry, although with an important and unanticipated trade-off between managing street tree canopy type and amount. Evidence was drawn from monitoring a set of residential street...
