The Tree Council of Ireland and the Irish Tree Society initiated the Tree Register of Ireland project in 1999 with the aim of compiling a database of trees in Ireland. To date, there are over 11,000 trees on the register which are recorded using GPS technology to accurately determine tree location. 

Of the trees on the database, some 3,000 had previously been recorded by Alan Mitchell on behalf of the
Tree Register of the British Isles. Mitchell covered many of the large estates, public parks, and gardens throughout Ireland. However, many of Ireland's finest trees are found on private farmland and in gardens. The Tree Register of Ireland endeavoured to both update the tree measurements taken by Mitchell and to locate and record new trees which were growing in less conspicuous locations.

The Register can be viewed at the National Botanic Gardens, Glasnevin Dublin, and provides the most comprehensive database of outstanding tree specimens in Ireland.

In order to keep it reasonably up to date, ideally, 10% of the database should be re-measured every year but unfortunately, we are behind in relation to the updating of this valuable tree resource due to a lack of funding.

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

In 2011, a selection of trees from the database was compiled for accessible use online. It was a project that consisted of listing over 5,200 specimen trees. The result is a dataset that is divided by county, name, species, common name and cultural significance complete with photographs, details and location.

 

It was hoped that over time that this dataset would equally continue to be updated but due to
lack of funding, it too is presently on hold.
