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...

In the Pacific Northwest, cold-water species like salmon are important for recreational sport fishing as well as for commercial fish production. However, climate change is causing lower and warmer summer stream flows that could decimate these fish populations. Aquatic cold-water habitats are further threatened by stormwater runoff, which moves from streets to storm drains and then is often discharged into cold-water rivers and streams. The urban heat island effect (when cities and urban areas are warmer than surrounding rural areas) may heat the temperature of the runoff and if the runoff is very warm, it could tip salmon habitat into fatal conditions. However, specifically how urban warming – or cooling, such...

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...
