Production of Christmas trees in Austria has increased enormously in the preceding 20 years. At present, Norman's fir (Abies nordmanniana), the main conifer species used for Christmas trees, is widely cultivated in Austria. Seeds as well as plants are imported from various European countries. Seeds of Picea-species are commonly imported from North America. There is nearly no propagation of Christmas-tree seeds in Austria, especially not of Norman's fir and other firs. The fact, that Christmas trees are cultivated as monocultures and the intense import of plant material are a high risk for the invasion and spread of harmful pathogens.
