2015 Oregon Invasive Species Council Directory

Jas. Jeffrey Adams, Willamette University College of Law
                                             Appointed Member through December 31, 2016

Jas Adams is currently an adjunct law professor at Willamette University College of Law, where he has taught Wildlife Law since 2002. A graduate of Reed College and Boalt Hall Law School, Jas. has focused on environmental and natural resource law for much of his legal career. Early on, he worked for several environmental public interest organizations, followed by stints as a judicial staff attorney and partner in private practice. In 1989, Jas. moved to the Oregon Department of Justice, where he handled many natural resource appeals, and he ultimately became Attorney-in-Charge of Natural Resources. In the 2011 session, Jas conceived, drafted and helped secure passage of HB 3399, which created an administrative search model to allow mandatory roadside inspection and decontamination of aquatic invasive species (AIS) without criminal liability for those motorists cooperating with the checkpoint program when transporting injurious wildlife. As a representative of the Oregon Attorney General, Jas. served as a working group member of a two-year effort to craft model state provisions to help overcome the patchwork of state and local laws on invasive species; he was a featured speaker on AIS at the June 2014 annual meeting of the National Association of Attorneys General on Mackinac Island in Michigan. In his wildlife law course, Jas has emphasized the dynamic relationship between science and law, the challenge being how to utilize scientific information in implementing effective programs that will withstand scrutiny. Jas notes: "The OISC is well positioned not only to ensure that those with scientific expertise are answering the right questions but also to recommend legal mechanisms that will nimbly adapt to rapidly changing circumstances."

Jim Seeley, Executive Director of the Wild Rivers Coast Alliance (WRCA)
                                Appointed Member through December 31, 2016

Currently Jim Seeley is Executive Director of the Wild Rivers Coast Alliance (WRCA), a philanthropic arm of Bandon Dunes Golf Resort with a mission to fund community projects on the South Coast of Oregon that are committed to the triple bottom line (conservation, community, economy) and prioritize approaches that blend innovative ecological initiatives while driving economic opportunity.  Prior to joining WRCA, Jim served for over 17 years as the Executive Vice President of Operations for KemperSports, a golf management company headquartered in Northbrook, Illinois. While at KemperSports, Jim was responsible for golf property operations including Bandon Dunes Golf Resort. He launched the KemperSports Green to a Tee™ environmental program which includes Integrated Pest Management as an important element in golf course maintenance practices. In recognition of his contributions to KemperSports, the company has named its highest annual individual award the James R. Seeley General Manager of the Year Award. Bandon Dunes has developed a love/hate relationship with gorse. The property was once heavily overgrown with gorse which had a lot to do with its availability for golf. That’s the love part. The ongoing difficulty and expense of managing it makes it easy to hate. It is now a primary target of WRCA’s regional working lands initiative to find effective solutions to gorse management. Jim is a 1964 graduate of the United States Naval Academy. He served on active duty for six years following graduation with the final two of those years as a faculty member at the Naval Academy teaching leadership, management, and naval tactics before entering the golf business.

Cat de Rivera Cat de Rivera, Portland State University
Ex-officio member

Dr. Cat de Rivera joined the Council in 2015 as the Portland State University representative. She studies how anthropogenic changes in habitat connectivity –whether because of biological invasion, roads and the built environment, or sea level rise—affect animal populations and communities. She combines behavioral ecology techniques with modeling and experiments to address questions about invasions ecology, road ecology, and restoration ecology. She aims both to provide resource managers with findings to help them determine the ecologically best management options as well as to conduct basic research that helps promote our more theoretical understanding of the ecology of marine, estuarine, and terrestrial systems. She teaches a variety of courses including Ecology and Management of Bio-invasions.
