About the Authors
Dr. Alan Herlihy is a senior research professor at Oregon State University in
the Department of Fisheries and Wildlife. His current research projects focus
on developing survey design methodology, assessment approaches, and ecological indicators for assessing surface water ecological condition at large
regional scales. He was a primary technical contributor to the 1990 National
Acid Precipitation Assessment Program’s Integrated Assessment report to
Congress, the EPA/Environmental Monitoring and Assessment Program
(EMAP) Mid-Atlantic Highlands Stream Assessment, and the Western Streams
and Rivers Assessment. He was the primary author of the chapters in the EMAP
stream and river field manual on water chemistry sampling, qualitative site
assessment, and sample reach layout. Currently, he is involved with the data
analysis and assessment of the National Aquatic Resource Surveys conducted
by the EPA Office of Water.
James Webb holds a BS in environmental science from Davis and Elkins
College, Elkins, West Virginia (1983) and an MS in environmental science
from the University of Virginia, Charlottesville (1988). He is presently a senior
scientist in the Department of Environmental Sciences at the University
of Virginia, where he served for 25 years as projects coordinator for the
Shenandoah Watershed Study and the Virginia Trout Stream Sensitivity Study
(http://swas.evsc.virginia.edu). He has authored and coauthored numerous
reports and journal articles concerning watershed response to atmospheric
acidic deposition in the forested mountains of the central Appalachian
Mountains region. He has participated in the design and management of
water quality studies and surveys, monitoring programs, and assessments
related to national park, national forest, and other conservation lands in the
region. He served as an academic community representative on the Technical
Oversight Committee and as coauthor of the Aquatic Effects Technical Report
for the multiagency Southern Appalachian Mountains Initiative. He has contributed to multiple National Park Service assessments, including participation as coprincipal investigator for the Shenandoah National Park: Fish in
Sensitive Habitats project and the Assessment of Air Quality and Air Pollutant
Impacts in the Shenandoah National Park. He was a coauthor of the Trout
Unlimited report, Current and Projected Status of Coldwater Fish Communities
in the Southeastern US in the Context of Continued Acid Deposition. He has contributed to EPA reports on status and changes in the acid-base chemistry of
surface waters in the United States related to implementation of the Clean
Air Act. His previous involvement in protocol and standard operating procedure development for environmental monitoring has included work for the
National Park Service and the US Department of Agriculture Forest Service.
