Aim Of Project

To record and measure prosperity of different varieties of Alder in local climate and conditions as possible alternative to Elm.


Seven Oaks,  St. Brelade, Jersey

In 1990 we planted 18 different species of alder along the valley floor at Seven Oaks in St Brelade, forming a collection unique within the British Isles. The project was in part a response to the devastating impact of Dutch elm disease throughout the 1980s, with the additional aim of identifying which species are best suited to our climate and soil.

The alders have now matured into wonderful specimens and the project has been recognised by Plant Heritage as a National Plant Collection.
