Abstract

V Sloveniji upravljanje divjadi tradicionalno temelji na spremljanju bioloških in okoljskih kazalnikih v okviru kontrolne metode. Vendar vse pogosteje spoznavamo, da za kakovostno trajnostno upravljanje in sodelovanje z deležniki potrebujemo tudi podatke o številčnosti vrst. V magistrski nalogi smo opravili pregled metod za ocenjevanje številčnosti srnjadi, ki je zaradi številnih ekoloških in gospodarskih pomenov ena naših ključnih vrst divjadi. Kot potencialno zanimivih za prenos v prakso smo izbrali 5 metod in jih preizkusili na prostorsko zaprti populaciji v LD Pšata, kjer prevladuje poljski ekotip srnjadi. Preskusili smo metodo neposrednega preštevanja osebkov, posredno vzorčenje z dvema metodama, ki temeljita na preštevanju kupčkov iztrebkov in uporabili dve metodi s populacijskim modeliranjem. Ocene različnih metod so bile zelo primerljive, nekoliko je navzdol odstopala le ocena z neposrednim preštevanjem. Na raziskovalnem območju po oceni s preštevanjem živi 149 osebkov. Z vzorčenjem kupčkov iztrebkov po metodi s predhodnim čiščenjem iztrebkov smo številčnost ocenili na 170 živali, podobno oceno 161 živali smo ugotovili tudi s statističnim modelom po Lefkowitchevi modelni zasnovi. Za izboljšanje upravljanja s srnjadjo v Sloveniji bi bilo smiselno v načrtovanje vpeljati kvalitativne podatke kot so ocene populacijskih gostot in drugih populacijskih parametrov.

Secondary title: Comparison of methods for estimating roe deer abundance
Secondary abstract: Wildlife management in Slovenia is based on monitoring biological and environmental indicators as part of traditional adaptive management. Informed management of wildlife populations requires an accurate estimation of abundance, especially for preserved management and collaboration with other interest groups. In master's thesis we studied different methods for estimating the population densities of our ecologically and economically most important game species. Based on literature review we prepared the set of 5 methods, which were tested in the spatialy closed study district of field ecotype roe deer population in LD Pšata hunting area. Estimation of population densities were carried out with direct total census, indirectly through faecal pellet % group count methods and population modelling. Density estimates were comperable. Lowest estimate of 149 animals was taken by direct census. With clearing plot method we estimated 170 animals and with Lefkowitch matrix model design 161 animals in the study area. Qualitative data as estimation of population densities and other population parameters in management would be required for improvement of wildlife management in Slovenia.
