Abstract
V Evropi človek že stoletja intenzivno spreminja pokrajino in vse bolj vpliva na ohranitveno stanje prostoživečih vrst. Mnoge evropske vrste so iz narave že izumrle, med njimi tudi evropski bizon ali zober. Vrsta je bila uspešno ponovno naseljena v številne države z obsežnimi ohranjenimi gozdnimi habitati. V Sloveniji imamo obsežne sklenjene površine gozdnih habitatov, ki ustrezajo zobrovim življenjskim pogojem. Glavni namen magistrske naloge je ugotoviti obseg in povezanost primernega prostora za zobra v primeru njegove ponovne naselitve v Sloveniji. S pomočjo modeliranja zobrove ekološke niše v programskem orodju Maxent smo napovedali potencialno primeren prostor na območju Slovenije. Izvedli smo modeliranje letnega in zimskega primernega habitata v primeru odsotnosti in prisotnosti človeka ter tako dobili rezultate za 8 različnih modelov. Najzanesljivejši rezultat smo dobili z modelom letnega primernega prostora ob prisotnosti človeka. Kot glavna območja primernega prostora so se izkazali Nanos in Hrušica, Trnovski gozd in Banjšice, Javorniki in Snežnik ter Kočevsko in Ribniško hribovje. Ta območja so med seboj nekoliko oddaljena in ločena z linijskimi objekti prometne infrastrukture. Za uspešno ponovno naselitev in prehajanje čred med območji primernega prostora bi bila potrebna vzpostavitev učinkovitih omilitvenih in upravljavskih ukrepov. Uporabljena metoda je primerna za tovrstno modeliranje, saj so napovedi modela kljub pomanjkljivim vhodnim podatkom zadovoljive. Za izboljšanje rezultatov priporočamo uporabo kakovostnejših vhodnih podatkov ter uporabo dodatne metode za primerjavo rezultatov. Poleg tega priporočamo vrednotenje dobljenega primernega prostora iz vidika drugih prostoživečih vrst, ki živijo na območju.

Title:European bison potential habitat prediction for reintroduction in Slovenia
Abstract:
For centuries, humans have been intensively using the landscapes in Europe, thus affecting the conservation status of several wildlife species. Many European species have already become extinct, including the European bison (Bison bonasus). The species has been successfully reintroduced to many European countries with extensive conserved forest habitats. Such extensive connected areas of forest habitats, suitable for the European bison, are also found in Slovenia. The main objective of the Master's thesis was to identify the size and connectedness of a suitable habitat in case of the European bison’s reintroduction. With habitat suitability modelling in Maxent, we predicted a potential suitable habitat in Slovenia. We performed the modelling of suitable summer and winter habitats with and without human-induced changes, thus producing eight different models. The model of a suitable summer habitat with human presence yielded the most reliable result. According to this model, the most suitable habitat is in the area of Nanos and Hrušica, Trnovski gozd and Banjšice, Javorniki and Snežnik, as well as the hills of Ribnica and Kočevje. The patches of a suitable habitat are not well connected to each other and are mainly separated by traffic infrastructure. The implementation of efficient mitigation measures and species management would be necessary for successful reintroduction and herd migration between habitat patches. Habitat suitability modelling with Maxent yields satisfactory predictions despite insufficient input data. To improve the results, we recommend using better input data and another method for result comparison. Besides, we recommend assessing the results from the aspect of other wildlife species living in the area.

Keywords:European bison, habitat suitability/selection modelling, Maxent, reintroduction, habitat patches
