Sweet chestnut Castanea sativa Mill. is an introduced species in the Czech Republic. It is recorded roughly from 300 localities. To the end of 2002, the occurrence of chestnut was verified at about 140 macrolocalities. The most northern locality recorded so far was Choustníkovo Hradiště in the region of Hradec Králové. Chestnuts occur generally to an altitude of 500 m (80% of all examined localities), at higher altitudes they suffer from climatic extremes particularly late frosts. The occurrence of chestnut was recorded at 27 localities (ca. 20% localities under investigation) where altitudes exceed 500 m. The highest location of chestnut is locality Nejdek, Karlovy Vary District where chestnut trees thrive at an altitude of 678 m. At altitudes over 600 m, two other localities were recorded. The health condition of chestnut is relatively good. At some localities, however, crown drying occurs as a result of not quite ideal climatic conditions. Within our research, quarantine Cryphonectria parasitica (Murr.) Barr. was determined for the first time in the Czech Republic at the only examined locality.
