Aim Of Project

To restore the arboretum and develop as a site for rare trees



Grand Route de Saint-Pierre, St Peter 

An arboretum is a botanical garden devoted to trees. As you walk around Val de la Mare reservoir you’ll notice various tree species which are clearly not native to Jersey. These include such fine specimens as eucalyptus, giant redwood, Korean birch and Japanese cedar.  

Val de la Mare Arboretum comprises twelve distinct tree collections: 

  1. Australasia Collection 
  2. American Collection 
  3. Birch Collection 
  4. Chinese Collection 
  5. Conifer Collection 
  6. Elm Trial Collection 
  7. Japanese Collection 
  8. Mediterranean Collection 
  9. Mixed Oak Collection 
  10. North American Collection 
  11. Pine Collection 
  12. Walnut and Wingnut Collection 

The Australasia Collection was seriously affected by the storms of January 2023, with several eucalyptus trees upended or otherwise damaged and a clean-up cost of around £1,500.

Some of the specimens survived, however, providing a reminder of the hardiness of nature in addition to that of its sheer power.

Val de la Mare Arboretum was created by the Moores family in 1975 in memory of their son, Nigel. Seeds were carefully sourced from around the world and planted by the States of Jersey. Once the initial funding had ended, however, ongoing care of the trees suffered and the area became neglected.

In 2021, Jersey Trees for Life entered into an agreement with Jersey Water to assume responsibility for planting, maintenance and ongoing care of these diverse and wonderful trees.  

More recently we have been working with leading plant biologists to map all the trees of significance within the arboretum, to write a collections policy and to formulate an overall plan for the area which will dictate how it develops over the coming decades. All Copyrights Reserved 2023
