Who we are

The Tree Register of The British Isles

The Tree Register is a charity registered as the The Tree Register of the British Isles, whilst often referred to as The Tree Register of Britain and Ireland, or simply by its acronym TROBI. It covers all of Britain, Ireland, the Channel Isles and the Isle of Man.

The Register is a unique database of over 270,000 of our most notable trees, recording our wonderful tree heritage and where you will find the definitive list of champion trees. 

CHAMPION TREES are either the tallest or those with the largest trunk circumference (girth) of their type and a database of 80,000+ champion trees is available online here to members.

The Tree Register has no paid staff and is run solely by volunteers. The membership scheme is a valuable source of income to support the website and the costs incurred curating and updating the Register.
