Abstract

Diplomska naloga je namenjena oceni stanja in opredelitvi varstvenih ukrepov zavarovanega Gašperjevega kostanja pri Radečah. Ob pregledu drevesa in rastišča je ugotovljena prisotnost več različnih vrst gliv (sivi lupinar - Amanita vaginata, hrastova korenovka - Collybia fusipes, kostanjev rak - Cryphonectria parasitica, jetrasta cevača - Fistulina hepatica, žvepleni lepoluknjičar - Laetiporus sulphureus, rdeča polstenka - Xerocomus rubéllus) in ovrednoten njihov pomen za drevo. Ocenjena je tudi potencialna nevarnost škodljivih dejavnikov, ki še niso prisotni, in kot najpomembnejša dejavnika sta ugotovljena Dryocosmus kuriphilus in Phytophthora cambivora. Drevo je dokaj vitalno, pojavljajo se suhe veje kot posledica sušenja zaradi kostanjevega raka, vendar je prisotna hipovirulenca, ki zmanjšuje vpliv bolezni. Poleg kostanjevega raka ogrožata obstoj drevesa glivi, Laetiporus sulphureus, ki povzroča hiter razkroj lesa in Collybia fusipes, ki povzroča odmiranje korenin. Kot ukrep za varstvo drevesa je potrebno temeljito obžagovanje suhih vej, pri tem pa je potrebna pazljivost, da se živi deli drevesa čim manj poškodujejo.

Secondary title:	Health and protection of Gašper's sweet chestnut in Radeče
Secondary abstract:	The purpose of this graduation thesis is to evaluate the condition and to propose protection measures for the protected Gašpers chesnut tree in Radeče. Survey of the tree and its sourrounding revealed the presence of different fungal species: Amanita vaginata, Collybia fusipes, Cryphonectria parasitica, Fistulina hepatica, Laetiporus sulphureus, Xerocomus rubéllus. Their impact to the health of the tree is evaluated. Harmful biotic factors which are potentionally threatening the tree but are not yet present are also evaluated. Dryocosmus kuriphilus and Phytophthora cambivora are identified as the most important. The tree is rather vital. Besides chestnut cancer the most serious threat for the existence of the tree are the fungi Laetiporus sulphureus which decompose the wood quickly and Collybia fusipes which is the cause of root dieback. As a measure of tree protection there is a need for radical prunning of dead branches, while trying to minimize the damage done tothe living parts of the tree.
