Abstract
V magistrski nalogi smo želeli preveriti vrstno pestrost metuljev na izbranih travnikih v občini Domžale. V ta namen smo od konca aprila do konca avgusta izvedli osem terenskih popisov na skupno 14 lokacijah. V tem času smo popisali 49 različnih vrst dnevnih metuljev, od katerih je šest vrst uvrščenih na rdeči seznam ogroženih vrst v Sloveniji. V občini Domžale prevladujejo splošno razširjene vrste, ki so zelo pogoste tako v Sloveniji kot drugod po Evropi. To lahko pripišemo različnim dejavnikom, med katerimi je najpomembnejši intenzifikacija kmetijstva, ki je izrazita predvsem v ravninskem delu občine Domžale. Na intenzivno rabljenih travnikih je poleg manjše vrstne pestrosti ter odsotnosti nekaterih vrst metuljev značilna tudi odsotnost vrst kukavičevk, ki so prav tako pomemben pokazatelj ohranjenosti travnikov. Na območju občine Domžale smo našli osem rastišč kukavičevk. Najpogostejša na obravnavanem območju je navadna kukavica (Anacamptis morio), nekoliko redkejša na območju Domžal pa je trizoba kukavičevka (Neotinea tridentata). Na podlagi vrstne pestrosti metuljev in prisotnosti kukavičevk, s poudarkom na ogroženih in zavarovanih vrstah, smo določili naravovarstveno vrednost lokacij ter preučili vplive biotskih in abiotskih dejavnikov na vrstno pestrost metuljev. Ugotovili smo, da naravovarstveno pomembnejši travniki ležijo na hribovitem delu občine Domžale, tj. v Dobovljah, Vinjah ter v Brdu pri Ihanu. Z izjemo travnika v Vinjah so omenjeni travniki del zavarovanega območja Spominskega parka revolucionarnih tradicij občine Domžale, kjer so posegi v okolje že omejeni. Naravovarstveno najpomembnejši travnik leži na ravninskem delu občine v Zaborštu pri Domžalah in je eden redkih ravninskih mokrotnih travnikov s kukavičevkami. V namen ohranjanja danes redkih in ogroženih ekstenzivnih travnikov v občini Domžale ter njihove biotske pestrosti bi bilo potrebno uvesti spremembe v gospodarjenju s travniki, predvsem omejitve vnosa gnojil in pesticidov ter prilagoditi čas košnje travnikov po koncu cvetne sezone.

Title:The importance of extensive meadows with wild orchids for butterflies in municipalty of Domžale
Abstract:
In our study we surveyed the butterfly diveristy on selected grasslands in the Municipality of Domžale. In order to achieve this, we carried out eight field surveys at each of the 14 locations between the end of April and the end of August. A total of 49 different butterfly species of which six are listed as endangered in Slovenia. Predominantly widespread and common species in Slovenia and Europe were observed in the Municipality of DomžaleWe can atribute that to various factors, among which the most important is the intensification of agriculture, which is particularly pronounced in the flatter parts of the Municipality of Domžale. The intensified grasslands are characterised by lower butterfly diversity, absence of habitat specialists and orchids which are also important indicators of the quality of the grasslands. We found orchids at eight locations in our study. The most frequent was Anacamptis morio, while Neotinea tridentata was much rarer. We calculated nature conservation value of each location based on butterfly and orchid diversity, with added weight for the presence of protected or endangered species. We also studied the effect of different biotic and abiotic factors on the butterfly diversity. We determined that the locations of the highest nature conservation importance congregate in the hillier part of the manucipality ie. in Dobovlje, Vinje, and in Brdo pri Ihanu. With the exception of the grassland in Vinje, the grasslands are part of the protected area of the Revolutionary Tradition Memorial Park of the Domžale municipality, where environmental changes are already limited. However, the most important nature conservation area is in the plain, at Zaboršt near Domžale. This is one of the last remining humid meadows with orchids in the flatter part. In order to conserve the rare and endangered extensive grasslands in the Domžale municipality and their biodiversity, changes in grassland mangment must be applied, especially concerning the limitations regarding fertilization and mowing of the meadows before the end of flowering season.
