The disease, caused by the pathogen Phytophthora ramorum, has been found in Japanese Larch trees in a Forestry Commission Scotland plantation on the Craignish Peninsula in Argyll.
In a bid to prevent the disease spreading, 1.25ha of trees are being felled in what Forestry Commission Scotland director Dr Bob McIntosh describes as a "real blow" to Scotland’s forestry.
The disease was first found in Britain in 2002 and has since been found on Japanese Larch in south-west England, Wales, Northern Ireland and the Republic of Ireland.
Any suspected cases of ramorum disease in larch trees in Scotland should be reported to the Tree Health Diagnostic & Advisory Service (DDAS) at the Forestry Commission’s forest research arm in Midlothian.
