Through the project, its organisers, which also include Cadwyn Clwyd, hope to see species such as pignut, meadow saxifrage and burnet-saxifrage flourish.
Sarah Jones, the environment and heritage officer for Cadwyn Clwyd - the regeneration agency which commissioned the survey - said side shoots on the trees are ideal cuttings.
Now, rural regeneration agency Cadwyn Clwyd has launched a project to revive small-scale hydro-electric power production in rural Denbighshire, launching feasibility studies for using water power on the Dee at Llangollen, and on the Alyn at Llandegla and Loggerheads.
