Tree propagation through seeds and cuttings is core to the project. These trees are raised locally in Bhré (Bray), then planted in several locations across Wicklow. These cuttings and seedlings are all Irish indigenous species supporting hundreds of insects, birds, fungus and other life forms. These are mainly hawthorn, blackthorn, oak, Scots pine, elder, hazel, willow, with the addition of Spanish chestnut trees.
