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.
