Join us on 4 November 2026 as the National Tree Officers Conference returns for another unmissable gathering of tree professionals from across the UK in Sheffield.

Tickets are on sale at £55 from the ICF  National Tree Officers Conference 2026 - The Institute of Chartered Foresters

We’re delighted to be bringing NTOC to Sheffield for the first time, and the conference will once again bring together leading voices from arboriculture, urban forestry, woodland management, and planning to share knowledge, explore emerging challenges, and showcase innovation in the management of trees and green infrastructure.

Proudly hosted by the Association of Tree Officers, Institute of Chartered Foresters, London Tree Officers Association, and the Municipal Tree Officers’ Association, the conference provides a unique platform for local authority tree professionals and the wider sector to connect, learn, and exchange ideas.

Over the years, NTOC has established itself as a key event in the arboricultural calendar, offering an invaluable opportunity for practitioners to share real-world experiences, discuss policy and practice, and engage with the latest research and developments affecting the sector.

Whether you are an experienced tree officer, a planning professional working in green infrastructure, or an early-career arboriculturist, NTOC 2026 will offer practical insights, professional development opportunities, and plenty of inspiration. The programme will feature a range of expert speakers, case studies, and presentations exploring the challenges and opportunities facing those responsible for managing our urban treescapes.

As the sector continues to respond to climate change, biodiversity loss, development pressures, biosecurity threats, and increasing public expectations of green spaces, NTOC 2026 provides a timely forum for discussion and collaboration. The conference will bring together a community of professionals committed to ensuring trees continue to deliver environmental, social, and economic benefits for generations to come.

Attendees can expect a day of thought-provoking presentations, valuable networking opportunities, and engaging discussions that will help shape the future of arboriculture and urban forestry. Whether you are looking to share experiences, gain new perspectives, or strengthen professional connections, NTOC 2026 promises to be a rewarding and inspiring event.
