Expansion range of the golden jackal in Hungary between 1997 and 2006

Abstract

The golden jackal (Canis aureus), an indigenous predator of Hungary, is listed in the Hungarian Red Data Book as an extinct species because it had disappeared from the country by the beginning of the 20th century. In the 1990s a repatriation process was started in the southern part of Hungary. To monitor the presence of jackals and/ or population changes countrywide, a questionnaire sur- vey was mailed to Hungarian game management units (GMUs) between 1997 and 2006. Proof specimens, field observations and hunting bag data were also analysed. During the study period approximately 100 proof speci- mens were identified. According to official hunting bag data, the number of bags reported has continuously increased for 10 years, with 11 jackals shot in 1997 and a total of 163 specimens shot up to 2006 (linear regres- sion, R 2 s0.949, p-0.0001), which is in parallel with the four animals reported by GMUs in 1997 and the total of 67 up to 2006 (linear regression, R 2 s0.983, p-0.0001). Detection of animals and their signs proves the contin- uous presence and the existence of stable populations of the species. Independent data collection and analysis confirmed that golden jackals have settled in Hungary. The rate of expansion and population growth are typical of invasive species.
