Wally Erickson

Senior Biometrician

Wallace P. Erickson has been a statistician with WEST since 1991. He currently serves as a senior biometrician/scientist. He has a M.S in Statistics from the University of Wyoming and a B.S. in Mathematics and Statistics from Winona State University. Wally has also previously served as the COO and CEO of WEST. He has over 27 years of consulting experience related to the design and analysis of environmental and wildlife studies. Wally’s work at WEST has involved applying proper experimental design and appropriate statistical analysis methods for natural resource studies. He has worked with numerous government, industry, and environmental organizations to help solve wildlife and other natural resource conflicts and issues. He has been a project manager and/or lead statistician for over 300 studies/projects, including baseline wildlife and risk assessment studies, environmental permitting, and/or operational monitoring/research at over 100 renewable energy projects in 35 states. Wally has provided written and verbal expert testimony in a variety of areas, including local, state, and federal permitting of energy projects. He has worked closely with several energy companies in providing technical assistance in development of their internal environmental policies, as well as providing expert guidance and input on local, state, and federal energy guidance.

Wally has studied, modeled, and estimated bird and bat mortality from many anthropogenic sources, including collision sources like communication towers, overhead lines, solar facilities, and wind turbines, as well as other sources such as pesticides and feral/outdoor cats. He has worked on hundreds of renewable energy projects throughout the U.S., working with both private industry and government entities to provide permitting, baseline, post-construction, and research studies. An advocate for science-based innovation, Wally has been involved in studies and modeling efforts evaluating the practical and effective use of remote sensing methodologies such as radar, thermal imaging, CCD cameras, and acoustic sensors for detecting birds and bats. He has also studied methods used to reduce, minimize, or mitigate impacts, including acoustic, visual and olfactory deterrents; prey reduction through habitat manipulation; habitat enhancement; power pole retrofitting; feral cat removal; marking lines, fences, and windows; and lighting reduction schemes at facilities. Wally has also applied and developed resource/habitat selection methodology, including, for example, studies of moose and brown bear habitat selection in Alaska.

He is an author/co-author on over 50 professional journal articles, book chapters, or peer-reviewed proceedings papers and co-author of the 2nd edition of the book “Resource Selection by Animals.” He has presented over 50 papers/posters at national/regional meetings.
