Welcome to the International Society of Arboriculture
UK and Ireland Chapter

The International Society of Arboriculture (ISA) is the worlds biggest group of professional arborists with over 20,000 members distributed throughout 38 “Chapters” across the 5 continents.

The ISA operates in the United Kingdom & Ireland via its UK & I Chapter. The Chapter formed in 1992 to represent the UK based professional arborist and to promote an international platform for the advancement of the science of arboriculture. Take a look at the United Kingdom & Ireland arm of the largest and most influential arboricultural organisation in the world.

Focused on individuals…

ISA has always been focused on the individual and personal growth. Joining the UK & I Chapter and the main ISA is a good way for anyone related to the Arboriculture industry to begin to make the continuing personal investment that enhances professionalism by expanding the range of skills and knowledge that an arborist brings to work.

People who develop such skills and adopt the committment to grow throughout their working life will recognise the call “Life-long Career Arborists Belong Here”. It’s about exposing yourself to positive influences and people who have the same mindset as you do. Discover what you are capable of by attending the seminars, conferences and competitions and you will see how this profession we call Arboriculture is evolving around the world.
