On the basis of historical and recent cadastral maps, topographic maps, and aerial photographs, we analysed changes in forest area within the cadastral units of Karpniki village, in the Karpnicki Potok (SW Poland). In 1823−2012, forest area increased there from about 41% to over 57% of the total area. The greatest increase has been recorded recently. Moreover, at that time over 16% of land classified officially as farmland was naturally colonized by communities dominated by woody plants. This seminatural process in the analysed case does not pose any serious threat to natural resources, but a complete lack of its control may lead to deterioration of the value of the local landscape and development of low−quality forest stands. The observed changes seem to be typical of other areas located in lower parts of the Sudety Mountains.

Dutch elm disease (DED) still occurs in Poland. Previous studies confirmed occurring O. ulmi and two subspecies of O. novo-ulmi: subsp. novo-ulmi and subsp. amerciana. In this study the population of Ophiostoma occurred in Poland was investigated. The disease incidence was investigated on elms growing in 39 locations. The pathogen’s mycelium was isolated from elm branches and twigs collected from 22 plots. The disease symptoms were noted in 5% to 35% trees. Fungi were identified based on the PCR amplification of the ITS 1/2 rDNA together with phylogenetic analysis of this region. Ophiostoma novo-ulmi was the only agent caused DED on Ulmus glabra, U. minor and U. laevis. There were no genetic diversity of O. novo-ulmi Polish population in analyzed ITS region. All kind of specific symptoms and disease intensity occurred independently on elm species and host age. Ulmus minor was infested most sever among the three elms species.
