Tree Register of Ireland

The Tree Register of Ireland (TROI) was jointly initiated in 1999 by the Tree Council of Ireland and the Irish Tree Society and to date has generated over 11,000 records of champion trees. A ‘champion’ tree is defined as the tallest or oldest or most massive example of its species or kind in a given region. This project is to undertake field survey work to update and expand the Champion Tree Register of Ireland.

Currently the Register is expanding at a rate of  about 1,000 trees each year.

In order to keep the Register reasonably up to date ideally 10% of the database should be re-measured every year. Currently (2016) we are behind in relation to updating the database of this valuable tree resource due to lack of funding
