Abstract

V magistrski nalogi smo raziskovali pestrost dnevnih metuljev in kukavičevk na 15 ekstenzivnih travnikih v Beli krajini. Zaradi dobre raziskanosti dnevne metulje in kukavičevke uporabljamo kot bioindikatorje ohranjenosti okolja. Njihova številčnost v Evropi v zadnjem obdobju drastično upada, saj so tako eni kot drugi zelo občutljivi na spremembe v okolju. Med drugim jih ogrožajo intenziviranje kmetijstva, prepogosta košnja in klimatske spremembe. Skupno smo popisali 70 vrst dnevnih metuljev, med katerimi je 11 ogroženih, štiri pa so zavarovane. Na podlagi vrstne pestrosti metuljev in kukavičevk smo naravovarstveno ovrednotili posamezne lokacije. Potrdili smo delno pozitivno korelacijo vrstne pestrosti dnevnih metuljev od dolžine roba lokacije in gozdnega roba lokacije. Za vrstno pestrost dnevnih metuljev in kukavičevk je ključno ohranjanje ekstenzivnih travnikov s prilagojenim gospodarjenjem – z akcijskimi načrti, izvajanjem monitoringa in izboljšanjem upravljanja njihovega habitata.

Secondary title: Evaluation of conservation value of extensively used grasslands in Bela krajina based on species richness of butterflies and wild orchids
Secondary abstract: In our study we investigated the biodiversity of the butterflies and orchids on 15 extensive grasslands in the region Bela krajina, Slovenia. Butterflies and orchids are used as biodiversity indicators because of their fast response to changes in agricultural practices. Their populations have declined drastically due to their sensitivity to the environmental changes. They are threatened due to intensive agriculture, forestation, climate changes, etc. Altogether we documented 70 species of butterflies, of which 11 were endangered and four were protected in Slovenia. Conservation value of each site based on presence of threatened species and total number of species of butterflies and orchids was calculated. We confirmed a weak positive correlation between butterfly species diversity and the length of the edge of the location and percentage of the forest edge. Adjusted management of extensive grasslands is crucial for butterfly and orchid diversity conservation including action plans, monitoring and better management of endangered species habitats.
