What makes a priority pest or disease for Observatree? Celebrating 10 years of Observatree.
Dr Charles Lane, Consultant Plant Pathologist at Fera Science Ltd., has been an integral part of the Observatree team since the project was launched, helping to provide technical tree health advice and training to the volunteers. Every year Charles leads on a review of the list of Priority pests and diseases that are the focus of Observatree. The number of tree pests and diseases known to be present in the UK has increased in recent years and others are thought to be heading our way. Which ones are of greatest concern? Are they suitable for citizen science? In this webinar, Charles outlines the current concerns within tree health, the importance of reviewing the Observatree Priority list and how he works with tree and plant health colleagues to recommend changes to the list.
