General Comments

Fungal pathogen causing canker disease on firs, confirmed in 2015 at two sites in the UK, although likely to have been present for much longer. Significant damage has been observed in Norway and Denmark in recent years. Growers of fir trees may wish to monitor for its presence and take management action when found.
