Trees are vital – bringing nature into urban areas, supporting the rural economy, providing food and habitat for wildlife and helping combat climate change. However, the number of pests and diseases has increased in the past few years and our trees are under threat. If you’re interested in monitoring tree health, why not come along to Ty Hyll to join Bob Griffiths from the Open Air Laboratories and take part in the OPAL Tree Health Survey! This is perfect for anyone interested in woodland management. Bring sturdy walking boots and plenty of refreshments with you! Open to all!

Open to volunteers and non volunteers. Limited parking available, please get in contact for more details! bethan@snowdonia-society.org.uk
