Assessment of the impact of sarcoptic mange on the goral population
In this study, changes in the takin population are used as the reference. Because of the impact of coronavirus disease 2019 (COVID-19), staff did not place the infrared camera in 2020. Therefore, only infrared camera (SG-880V, Bestguarder, China) data from 2018, 2019 and 2021 were analyzed. The results showed that the number of gorals decreased rapidly in 2021 and was significantly lower than those in 2018 and 2019 (p<0.05) (Fig. 2B). There was no significant change in the number of takins in 2018, 2019 or 2020. This shows that sarcoptic mange led to the mass death of gorals, consistent with the results of the survey.
