Welcome to our third newsletter of the year! Our major activity for March is our Walk for the Woods fundraising event on Saturday, 17th March, starting any time between 10 a.m. and 2 p.m. We will be walking the distance between Warley Woods and Tipperary. It is indeed a long way—80 miles. The more people that you can get to sponsor you, the more money we can raise to help look after our beautiful woodland. More information is available on our website.
