“…Home ranges of long-tailed gorals vary depending on seasonal climate and on geographic factors such as natural barriers and habitat steepness, but are less than 1 km 2 (Myslenkov and Voloshina, 1989;Ministry of Environment of Korea, 2002;Cho et al, 2014). This implies that members of this species are unlikely to disperse long distances from their birth site.…”

The long-tailed goral, Naemorhedus caudatus, is an internationally endangered species. This species is distributed throughout Northeastern Asia including Northeastern China, the Russian Far East and the Korean peninsula. The population size of long-tailed gorals is currently decreasing in South Korea, and thus effective conservation of the animal is urgently needed. Although the evolution and phylogeny of this animal have been studied, population genetic studies are needed to design effective conservation and management strategies. To evaluate the present status of genetic diversity and genetic structure of long-tailed gorals in South Korea, we investigated genetic variability among 68 goral individuals from different regions, including 11 captive zoo animals, at 12 microsatellite loci. The level of genetic diversity was moderate in wild goral populations, but lower in the captive group. The goral population from the lower northeast region of South Korea was distinct from the upper northeast population, probably due to the natural climatic and geographic conditions. The genetic characteristics of the captive group were more similar to those of the upper northeast population than the lower northeast, confirming that the zoo animals originated in the Seorak Mountain range. Direct translocations between the upper and lower northeast populations are not currently recommended considering the natural population structure and the moderate levels of genetic diversity in the two populations. This study highlights the importance of genetic information in designing effective conservation strategies and translocations of endangered animals, including the Korean goral.

“…Small populations of wildlife can easily become extinct for a variety of reasons, including inbreeding, climate change, disease and invasive species (Shaffer 1981, Richman et al 1988, Berger 1990, Schoener and Spiller 1992, Keeling 1997, Allendorf and Lundquist 2003, Hodgson et al 2009, Wilder et al 2020. The long-tailed goral, or Amur goral (Naemorhedus caudatus), is one of the wildlife species which has a small population and is threatened with extinction in South Korea.…”

“…This species is an ungulate of the family Bovidae, which is found in a few forests or steep rocky areas in the mountains of the Korean Peninsula, north-eastern China and eastern Russia (Myslenkov and Voloshina 1989, Song et al 2017, Jo et al 2018. Recent studies using GPS collars (Cho et al 2014, Cho et al 2016 have shown that the goral is a sedentary animal with a relatively small home range of 0.58 to 1.46 km . Unfavourable factors, such as the cultivation and fragmentation of habitats, have led to a decrease in the number of populations and this species is classified internationally as vulnerable (VU) on the IUCN (International Union for Conservation of Nature and Natural Resources) Red List (Bragina et al 2020).…”

“…These methods need time-consuming efforts for the collection and analyses of faecal samples (Kim et al 2018, Jang et al 2020. Camera trapping provides accurate measurements of mammals since the repeated analysis of captured photos is possible and this is a more effective method than attempting to count by visual inspection in a field, because the rare individual is an endangered species or by morphometric analysis of faecal samples (Silveira et al 2003, Kelly and Holub 2008, Ahumada et al 2013. Cameratrapping has ever before been carried out for estimation of the long-tailed goral , Zaumyslova and Bondarchuk 2015).…”

The objectives of this study were to select morphological keys for the identification of individual endangered long-tailed gorals through analysis of photographic data and to use these morphological keys to determine the number and population composition of gorals living in the Osaek Region of Seoraksan National Park. Amongst 8149 photos taken using 73 cameras in the Osaek Region, 2057 photos of faces and horns were analysed. The presence and absence of horns, shape of the horns, proportion of the ring to the length of the horn and facial colour pattern were selected as morphological keys to identify individual gorals. To verify the accuracy of the morphological keys for identifying gorals, a blind test was performed on gorals residing in the sanctuary of the Yanggu Goral Restoration Center. The test revealed that the population and age of gorals were discerned correctly by the morphological keys, but there was a 12.5% error in discriminating between sexes in gorals aged over 10 years. Fifty-six gorals were identified from 2057 pictures, based on the morphological keys and methods developed in this study. The population of 56 individuals consisted of 43 individuals aged over 2 years (subadult or adult) and 13 offspring aged less than 2 years, with a ratio of 3.3:1. Of the total 56 individuals, 45% were adults aged 10 years or older, 18% were adults aged 3–10 years, 7% were subadults aged 2–3 years, 23% were offspring aged less than 2 years and 7% were individuals aged 2 years or older, whose age and sex could not be confirmed. The sex ratio of males to females was 1.17:1, with a corrected sex ratio of 1:1 considering the 12.5% error rate for gorals aged over 10 years, amongst the 39 gorals aged over 2 years.
