Investigation has been carried out on the communities of fungi developing in birch and Scots Pine chip piles in the Ostroleka Pulp and Paper Mill in the North-East of Poland The species composition or fungal communities and their development in a dozen of chip piles during storage was investigated. Untreated and chemically treated birch and pine wood chips were investigated. In all samples the great amount of Aspergillus fumigatus infested chips were found. This fungus displayed resistance to chemicals used as chips preservatives and occurred often more frequently in the wood of chemically treated than untreated chips.
