The ATO Directors would like to reassure all members that we are working hard to ensure business continuity for ATO at this exceptional time.  We are facing new and sometimes substantial challenges to our working and personal lives, and we are all having to adapt quickly to try to maintain the services we provide to our local authorities and clients.

Until further notice, ATO are making use of conference calls and other virtual meeting technology to continue with business.  

If you have any queries about the measures we are taking please let us know by email to Becky Porter on This email address is being protected from spambots.

From all of the ATO Directors we hope you are all keeping safe and well, and let us also hope that normality returns before too long.


The Association of Tree Officers (ATO) has emerged from the National Association of Tree Officers (NATO) and the London Tree Officers Association (LTOA) joining forces to build a stronger national organisation. ATO will represent and promote UK tree officers at a national and international level and support the work of the regional tree officer groups.

During the past year the ATO Directors have:

  • appointed new Directors
  • defined the ‘aims & vision’ of the organisation and written a new constitution
  • changed the name and designed a new logo
  • established a comprehensive business plan
  • drawn up a new membership package, which includes a range of benefits for both local authority and a new individual membership category
  • made regular contact with most of the regional tree officer groups in the UK through the Tree Officer Forum, providing the organisation with a ‘grass roots’ national perspective
  • become a National Tree Officer Conference (NTOC) steering group partner
  • been building the website to be an information resource for tree officers and other professionals

With the continued support of our membership and supporters and the strong links to regional tree officer groups, ATO is the national voice for tree officers. Standing together tree officers will have a stronger and unified voice, which can only be a good thing for tree officers.
