Trees face huge challenges
With more new pests and diseases reaching our shores tackling pests and diseases is now an urgent priorityLearn about the threats
Chestnut blight has now been confirmed in areas of England on sweet chestnut trees. It was first discovered in 2011, then again in early 2017 at nine sites in Devon and Dorset and in July 2017 in south east London.
Chestnut blight (Cryphonectria parasitica) is a fungus that infects and kills chestnut trees (Castanea species). It was responsible for killing most of North America’s chestnut trees (Castanea dentata) in the 19th and 20th centuries when it was accidentally introduced from Asia. It has also now become widespread across the European mainland since its introduction in the 1930s. In Europe it mostly attacks sweet chestnut (Castanea sativa).
The government introduced tighter controls for all imports of sweet chestnut (Castanea sativa) in November 2013 in response to the increased threat from sweet chestnut blight. Over the past few years this harmful fungal disease has decimated commercial crops in some European countries and has the potential to seriously affect sweet chestnut in our woodlands.
As a result anyone now moving sweet chestnut trees into, out of, or within, England and Scotland must ensure they hold the necessary plant passport confirming the plants have been grown in an area or country officially shown to free from the disease. In addition, the latest findings in England have resulted in movement restrictions of sweet chestnut material including plants, logs, branches, foliage and firewood out of, or within, six zones in Devon and Dorset. Full details of the specific zones can be found on the Forestry Commission website.
If you think you’ve spotted this disease please inform the Forestry Commission using the Tree Alert reporting tool. Three good-quality digital photographs are required to aid identification.
