Alder Collection - Jersey Trees For Life

In 1991 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.

We are incredibly grateful to CoinShares for funding new signage and better site access, thereby helping to share these beautiful trees with a wider audience.


Volunteering with Jersey Trees for Life is a fantastic way to help your local environment while doing yourself a world of good in the process. It’s good for mind, body and soul. Why not give it a go?

You can also support us by signing up for annual membership, with all proceeds helping us to plant and protect trees, educate the community and become Jersey’s “Voice of the Trees”.
