The Pacific Southwest Region of the Forest Service, in collaboration with the Pacific Northwest and Pacific Southwest Research Stations and the Office of Sustainability and Climate, formed a science-management partnership and conducted a climate change vulnerability assessment for infrastructure and recreation in Sierra Nevada national forests. The vulnerability assessment set the stage for developing adaptation options in a series of science-management workshops. The outcomes of the effort, called the Sierra Nevada Infrastructure and Recreation Vulnerability Assessment and Adaptation Partnership, are described in this report.

Climate change vulnerability and adaptation for infrastructure and recreation in the Sierra Nevada. Halofsky, Jessica E.; Peterson, David L.; Buluç, Lara Y.; Ko, Jason M. 2021. Gen. Tech. Rep. PSW-GTR-272. Albany, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Research Station. 275 p.

Exposure to ozone pollution has serious health risks. Damage to lungs and impairment of cardiovascular health are of particular concern for children, the elderly, and anyone whose health may already be compromised. This report describes three successive studies that led to the development of techniques for directly monitoring human exposure to ozone.
