Latest News

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.

The Diversity and Inclusion Working Party of the LTOA was formed in response to the Chair, Barbara Milne’s, call for an investigation into potential barriers to accessing the Arboricultural profession, particularly for women.

During the initial meetings they expanded this aim, to work towards improving accessibility in general, including encouraging people from different social and educational backgrounds, encouraging people from different cultural backgrounds, people with external demands on their time, to name a few.

Part of the issues surrounding accessibility is how Tree Officers promote their work and roles. Often this is through job advertisements and recruitment.

The initial findings found inaccurate information on public websites about the role of a Tree Officer. As a result, they have created a new, up-to-date job profile that they hope will improve people’s knowledge of the job requirements and subsequently encourage more diverse applicants.
