Poškodovanost gozdnih sestojev zaradi žleda v gozdnogospodarskih enotah Vrhe in Vremščica : diplomsko delo - visokošolski strokovni študij

Žled, ki je februarja 2014 prizadel skoraj polovico slovenskih gozdov, je poškodoval tudi 4.755 ha gozdov na Kraškem gozdnogospodarskem območju. Analizirali smo poškodovanosti gozdnega drevja v gozdnogospodarski enotah Vrhe in Vremščica. Uporabili smo podatke za 252 stalnih vzorčnih ploskev, na katerih je bila ocenjena vrsta in stopnja poškodovanosti dreves. Na območju žleda je poškodovane 68 % lesne zaloge v GGE Vrhe in 57 % lesne zaloge v GGE Vremščica. Približno tretjino poškodovanega drevja je treba zaradi velike stopnje poškodovanosti posekati. Pri listavcih, kjer ima bukev večinski delež v obeh GGE, je stopnja poškodovanosti okrog 70 %, pri iglavcih pa je stopnja poškodovanosti od 10 % v GGE Vremščica do 40 % v GGE Vrhe. Debelejše drevje s prsnim premerom nad 30 cm je bilo relativno bolj poškodovano kot tanjše drevje.

• Title: Damage of forest stands due to icestorm in Vrhe and Vremščica forest management units

Abstract

Ice storm that has affected nearly half of Slovenian forests in February 2014, also damaged 4.755 ha of forests in the Kras Forest District. We have analyzed the damage on trees in the forest management units Vrhe and Vremščica. With data of 252 sampling plots we assessed the type and degree of damage on trees. 68 % of the growing stock was damaged in forest management unit Vrhe and 57 % of the growing stock in forest management unit Vremščica. Because of the high degree of damage approximately one third of damaged trees was necessary to cut down. For deciduous trees, where the beech has the majority stake in both forest management units, the degree of damage was around 70 %. For conifers was the degree of damage from 10 % in the forest management unit Vremščica to 40 % in the forest management unit Vrhe. Less than one-third of small-sized diameter trees (breast height up to 30 cm) was damaged in both forest management units.
