Kontrolirani požari kot orodje za ohranjanje biodiverzitete ptic na Krasu

Šunta, Andreja (author), Jurc, Maja (mentor)

Namen diplomskega dela so bili analiza podatkov popisov gozdnih požarov ZGS med letoma 1995 in 2018, seznanitev o vplivih požarov in kontroliranega požiganja na gozdne ekosisteme preko člankov tujih in domačih avtorjev ter analiza pojavljanja vrtnega strnada na območjih, kjer so bili v preteklosti popisani gozdni požari večjih površin. Na primeru ogrožene vrste vrtnega strnada, ki je ptica odprtih habitatov na Krasu, ki se zadnja leta srečuje s problematiko zaraščanja krajine, smo poskušali ugotoviti, kako požari vplivajo na številčnost in biodiverziteto ptic. Prav na kraškem območju sta bili popisani dve tretjini vseh gozdnih požarov. Na območjih večjih pogorišč, kjer je v preteklosti gorelo na vsaj 10 ha površine, je bila opažena in popisana skoraj polovica vseh osebkov vrtnega strnada v Sloveniji. Pri zaključkih smo imeli težave z majhnim vzorcem, saj je populacija vrtnega strnada majhna in v upadanju. Pojavili so se tudi dvomi o primernosti uporabe kontroliranega požiganja v habitatih, kjer prevladuje črni bor, saj ta nima adaptacij na ogenj.

• Title: Controlled fires as a tool for conserving bird biodiversity on Kras

Abstract

The purpose of the bachelor thesis was to analyse data on forest fires collected by the Slovenia Forest Service between years 1995 and 2018 in order to get familiar with the effects of fire and prescribed burning on forest ecosystems. We looked into articles of both Slovenian and foreign authors as well as analysed the frequency of occurrence of ortolan bunting on areas where large scales forest fires had been recorded. We tried to find out the impact of fires on the abundance and biodiversity of birds on the example of the endangered species ortolan bunting, which occupies open habitats in Kras, in which overgrowth of agricultural land and its abandonment is a problem. Two-thirds of all forest fires happened in Kras. Almost half of all seen cases of ortolan bunting in Slovenia have been recorded on large, burned areas, where in the past 10 ha of land or more had burned. In conclusion, we struggled with a small sample, because the population of ortolan bunting is small and in decline. Doubts also arose about the usage of prescribed burning in habitats, where European black pine is predominant, which has no adaptations to wildfires.
