DISTRIBUTION AND HEALTH CONDITION OF SWEET CHESTNUT (CASTANEA SATIVA MILL.) IN THE CZECH REPUBLIC
Sweet chestnut (Castanea sativa Mill.) is widespread in the Czech Republic. It is an introduced species. The oldest report about the trees growing at Kamencové jezero, lake near Chomutov was noted by Balbín in 1679. It is recorded approximately from 320 localities in the Czech Republic at present. The data about tree position (using GPS), the girth, the total height and the state of health, completion of photography were digitized on the virtual map of the sweet chestnut occurrence. Trees grow mainly in parks, gardens, urban vegetation, but also in forest stands. We have only two sweet chestnut orchards in Nasavrky and Chomutov town. A causal agent of quarantine pest, chestnut blight, Cryphonectria parasitica (Murrill) M.E. Barr, is a serious problem in most sweet chestnut stands in Europe. The fungus was first found in the Czech Republic in 2002, in the town Uherský Brod, and in 2004 in two localities on Southern Moravia. Infected trees in these two localities were treated according to the order of State Phytosanitary Administration of the Czech Republic. A third locality is still investigated. This disease occurs both on the sweet chestnut and on oaks.
