Building on the success of previous conferences, and in light of the ongoing situation with Coronavirus (Covid-19), we’re excited to announce the fifth National Tree Officers Conference is being moved online.

This month-long event, developed by tree officers for tree officers, is a fantastic opportunity for tree, woodland and planning officers to present to their peers on the latest research, best practice and innovation in different areas of local authority arboricultural and urban forestry work.

The conference will be held over four weeks in November, beginning 2nd November 2020. Bookings for the conference will open on 17th August 2020.

Each of the four weeks will feature presentations covering specific topics. We’re looking for presentations for interactive, online sessions covering the following subject areas:

  • Week 1: Pests & Diseases
  • Week 2: Planting & Species Selection in a Changing Climate
  • Week 3: Planning
  • Week 4: Wildcard Session (any other topics outside those listed above)

The submission period for presentations is now open and will close on 6th July 2020.

Proposals must include your name, email address, presentation topic with overview (500-word maximum) and estimated duration. Presentations can be performed live or submitted prior to the conference in video format. We’re also keen to hear from tree officers who are interested in leading discussion groups relating to the various sessions that will be held throughout the month.  

Submissions will be reviewed by a committee, with selection criteria including quality, appropriateness, focus, the practical nature of material, and potential appeal to the audience.

Outlines should be sent by email to Becky Porter (LTOA): This email address is being protected from spambots. You need JavaScript enabled to view it.
