Short PRA (and report of PRA) produced in the framework of the EPPO Study of the risk of forest pests occurring on the territory of the former USSR for the western part of the EPPO region.  

This document supported the addition of this pest to the EPPO A2 list. 

The endangered area is primarily northern and central parts of the European EPPO region, as well as mountain areas of some other countries. Although the potential economic impact may not be high, since larch is not a major forest tree for the endangered area, the environmental and social effects may be significant in the mountain areas where larch is widely grown and has an important stabilizing effect.
