Adopt a tree Donate Over 1,500 trees in Warley Woods have their own unique number and you can adopt any one of them. It could be your favourite one or one which holds special memories for you. You can sponsor a tree for yourself or as a gift for someone else and know that your donation will help preserve this special place for yourself, your family and generations in the future. Annual adoption of a tree is £25. For this, you will receive a certificate which acknowledges your donation and which shows the location of the tree.
