The Government eDNA Working Group 7th eDNA Technical Exchange Workshop

The 7th Government eDNA Working Group (GEDWG) Workshop featured an in-person and virtual technical exchange conference coordinated by the GEDWG on September 17–19, 2024, at the Columbus Zoo and Aquarium in Columbus, Ohio, USA. GEDWG is a no-cost consortium that brings together stakeholders associated with federal, state, provincial, municipal, and other government agencies, universities, and various nongovernmental entities interested in environmental DNA (eDNA) and related fields. GEDWG shares technical expertise and experience during monthly online discussion meetings and annual workshops. Approximately 80 participants attended the 7th Workshop in person, and over 130 additional participants attended virtually. The Workshop featured seven keynote plenary speakers, five presentation sessions, 26 platform talks, 11 posters, and an overall discussion session. Attendees included research scientists, natural resource managers, conservation policy experts, industry professionals, and representatives of trade organizations and nongovernmental organizations. Key takeaways from the Workshop included moving the application of eDNA into resource management and developing ways to improve policy uptake for nationwide and worldwide biodiversity monitoring, including eDNA standard practices, eDNA networks, and national strategies. Suggested research directions that merit further growth include comprehensive studies of eDNA fate and transport in different environments, autonomous sampling/sample processing, and reference library curation. Additionally, the codesign of studies and improved engagement and communication among scientists, resource managers, and industry are needed to ensure clear expectations and outcomes and move forward with biodiversity assessments.
