Confluence Retirement

In an effort to consolidate USGS hosted Wikis, the myUSGS Confluence service is targeted for retirement on January 28, 2022. The official USGS Wiki and collaboration space is now SharePoint. Please migrate existing spaces and content to the SharePoint platform and remove it from Confluence at your earliest convenience. If you need any additional information or have any concerns about this change, please contact Thank you for your prompt attention to this matter.

Workshop sessions will run from approximately XX:00 am - XX:00 pm US Eastern Standard Time (UTC-5). We expect to record and later post presentations on the homepage (link above). The meeting will be hosted on WebEx.

Description: The 5th annual Environmental DNA Technical Exchange Workshop (5eDTEW) will be a virtual workshop hosted and coordinated by the Government eDNA Working Group (GEDWG). GEDWG is a no-cost consortium that focuses on bringing together scientists, natural resources managers, and other stakeholders interested in eDNA and related fields, for the purposes of sharing technical expertise and experience. Participants from outside federal, state, provincial, municipal, and other government agencies are welcome to join. For more information on GEDWG, please contact Richard Lance ( This workshop will emphasize methods for environmental DNA (eDNA) and eDNA metabarcoding studies (or eRNA studies), from study design through assay design, sample collection, processing, and results interpretation, and on to post-survey decision-making. The first workshop (1eDTEW), held in Denver in 2016, included more than 75 attendees from across government, academia, and private industry. The 2nd workshop (2eDTEW) in 2017 was held virtually and had over 200 participants. 3eDTEW was held in St. Petersburg, FL in 2019 and had over 125 participants.

Plenary Presentations by

Dr. Caren Helbing · University of Victoria
Dr. Teresita Porter · University of Guelph
Dr. Matthew Barnes· Texas Tech University
Dr. John Darling · USEPA
Dr. Rachel Meyer · CAL eDNA

The Workshop objective is to provide eDNA professionals with useful and actionable knowledge. Sessions include:

1. eDNA basics and developing standards

2. Data analysis/ interpretation and tools

3. Emerging technologies

4. Effective communication with natural resource managers

5. Citizen science with eDNA

Moderated open discussion sessions will be included in the 5eDTEW schedule.

Registration: No cost for attendance, but registration is required. All attendees should register prior to 12 October 2021. Register here: ( If limitations in attendee numbers become necessary, attendance will be determined on a “first come-first served” basis.

Presentations (No longer accepting abstracts)

Abstract deadline September 21, 2021. ( Presentations should focus on sharing important concepts or “lessons learned” in regards to application, procedure, etc., and not simply be comprised of overviews of past, on-going, or planned eDNA surveys.  Precedence may be given to completed studies. Accepted presentations will be assigned to an appropriate session by the 5eDTEW organizing committee. Talks should be 15 minutes total (approximately 12 minutes talk and 3 minutes for questions). Slides will be due to the session chairs by October 18, 2021.

Virtual poster/Blitz presentations: Each presenter will provide a poster in PDF format to the session chairs by October 18, 2021. Posters will be sent to all attendees at the start of the workshop. Each poster will be orally presented in a 5-minute slot with 3 slides. Poster presentations will be conducted in groups, followed by 10-minutes of questions for the group.

Abstract Guidelines:
1. Presentation Title
2. Name(s)
3. Affiliation(s)
4. Preferred format (Platform/Virtual poster)
5. Most Related Session/ Topic
6. Abstract (no more than 225 words)

Abstract Acceptance: Presentations will be allotted by the 5eDTEW organizing committee and accepted presenters will be notified by October 5, 2021.
