Sprememba favne kot posledica zaraščanja Krasa v zadnjih sto letih : diplomsko delo - visokošolski strokovni študij

Weber, Tiberij (author), Jerina, Klemen (mentor)

Habitatne spremembe na Krasu so bile v zadnjih sto letih tako izrazite, da so pomembno vplivale na spremembo zastopanosti nekaterih živalskih vrst. Te spremembe so predvsem posledica načrtnega pogozdovanja v sredini 19. Stoletja,kasnejšega spontanega zaraščanja in spreminjajočih se družbeno ekonomskih razmer. S pomočjo statističnih podatkov o odvzemu je bila ocenjena dinamika gibanja številčnega stanja jelenjadi, srnjadi, divjega prašiča, poljskega zajca, poljske jerebice in kotorne v zadnji sto letih. Dobljeni podatki so bili zaradi lažje primerjave preračunani na površinsko enoto 1000 hektarjev in vzporedno primerjani s stopnjo zaraščanja. Analizirani podatki so pokazali, da je pričela vzporedno z zaraščanjem najprej upadati številčnost vrst, navezanih na ekstenzivno obliko kmetijstva in odprtokrajino, hkrati pa se je na obsežnih območjih novonastajajočih gozdov pričela redno pojavljati velika divjad. Mala divjad, ki je bila v preteklosti najpomembnejša vrsta divjadi v območju, je do danes praktično izginila. Po drugi strani pa populacije srnjadi, jelenjadi in divjega prašiča stalno naraščajo, prav tako se veča tudi njihov življenjski prostor.

• Title: Changes in fauna due to overgrowing of the Karst in the last century

Abstract

Habitats in the Karst have been changing so profoundly in the last century that marked variations in the presence of some animal species have been observed. In the majority of cases, they are the consequence of the forestation in the middle of the 19th century; the ensuing spontaneous overgrowing of landscape; and changed socio-economic circumstances. The dynamics of fluctuations in the numbers of red deer, European roe deer, wild boar, European hare, grey partridge and rock partridge in the last century was estimated on the basis of statistical data on the taking. The data for the area of 1,000 hectares was calculated and compared to the level of overgrowing. The analysis showed that the number of species dependent on extensive farming and open landscapes have fallen as a result of overgrowth. Besides, large game has started to inhabit the recently planted forests. Smallgame that used to prevail in the area is almost extinct today. On the other hand, red deer, European roe deer and wild boar populations and their habitats have increased.
