Eugene, Oregon, USA – We are pleased to announce that the administration of the National Roster of Environmental Conflict Resolution Professionals has been transferred from the Morris K. Udall and Stewart L. Udall Foundation’s (Udall Foundation) John S. McCain III National Center for Environmental Conflict Resolution (National Center) to, a website designed and maintained by a partnership between the Association for Conflict Resolution/Environment and Public Policy Section (ACR/EPP) and

For over twenty years the National Roster of Environmental Conflict Professionals has been used by Federal agencies; Tribal, State, and Local governments; non-profit organizations; and the private sector to locate professional mediators, facilitators, and conflict resolution service providers. The publicly available, searchable database provides the public and practitioners a portal to broaden collaboration and conflict resolution networks and skills.

The National Center for Environmental Conflict Resolution has determined that future administration of the Roster will need to occur outside of the auspices of the Udall Foundation. Recognizing the value that the Roster has provided to the Environmental Collaboration and Conflict Resolution (ECCR) community, the National Center approached ACR/EPP and to take on the stewardship of the Roster moving forward. Together, and ACR/EPP have developed a sustainable framework that will maintain and manage the Roster to ensure it continues to benefit the field of environmental conflict resolution for many years to come.

“I believe the ECR Roster is an invaluable resource for federal, state, local, and tribal governments, as well as the private and non-profit sectors,” said Colin Rule, CEO of “As a website devoted to the expansion of quality conflict resolution for the last quarter century, we are delighted to help the Roster continue and evolve so as to promote collaboration and conflict resolution in resolving complex environmental disputes.”

Over 2023, the ACR/EPP and partnership will engage the Environmental Collaboration and Conflict Resolution community in developing new and exciting opportunities for practitioner-driven improvements to the Roster. In Phase One, will lead on technical development, migrating Roster members to the new platform. All Roster members will receive notifications about the move and will be able to log in to update their information. In Phase Two, the ACR/EPP Roster Advisory Team will update the Roster processes and criteria for application, review, verification, acceptance, and complaints. ACR/EPP member input will be gathered and integrated throughout both phases via webinars, dialogues, and ACR conference postering in common areas.

“The ACR/EPP section is both honored and delighted to steward the Roster with the help of our Advisory Team,” said Mary Dumas, Co-President of the ACR/EPP Section.  EPP Leadership Council members, will work with allied organizations and practitioners, academics, researchers, and innovators to uphold the national standards underpinning the Roster’s high regard, while modeling best practices in equitable facilitation and engagement in managing this transition.”

We welcome involvement from all Environmental and Public Policy conflict resolvers, (especially Roster members) in this new initiative.
