The Portland moss and air quality study
Moss growing on urban trees is a useful bioindicator of cadmium air pollution in Portland, Oregon, a U.S. Forest Service Pacific Northwest (PNW) Research Station-led study has found. Urban moss analysis could potentially revolutionize air quality monitoring by serving as a screening tool to help cities strategically place their air quality monitors. This research—the first to use moss to generate a rigorous and detailed map of air pollution in a U.S. city—is published in the current issue of the journal Science of the Total Environment. Plot data used in this journal article are now available.
The station will publish a comprehensive report this summer with basic maps of 22 heavy metals and other elements measured in the Portland moss samples. To be notified when this report is published, send an email to email@example.com with “Moss study list subscription” in the subject line.
Drought complicates threats to western forest land. Moisture-stressed trees are more susceptible to wildfire, insects, and disease outbreaks. The U.S. Forest Service Pacific Northwest Research Station’s Center for Advanced Forest Ecosystem Research (CAFER) has established a multidisciplinary, multiscale research program to document relationships between drought, temperature stress, and forest resource conditions. A virtual center, CAFER builds on the strength of senior scientists in the fields of remote sensing, landscape ecology, tree physiology, and hydrology. Working together, these scientist are developing new knowledge that will help land managers project the effects of climate change, better understand streamflow regimes, and develop strategies to support resilient forest ecosystems.
Yellow cedar is an important native conifer with a range from northern California to the Kenai Peninsula in Alaska. Although ecologically and economically important as well as an important species to Native Americans for its bark and wood, relatively little information has been available for yellow-cedar. This comprehensive website features yellow-cedar information, including a photographic guide of the species with more than 1,000 pictures. Pictures include shots of tree boles, tops of trees, and groups or stands of trees as well as specific features such as burls, bark, or foliage. The website includes links to several published or online sources of information on the species.
