In recent years,dead goral bodies were often found in winter and spring in subalpine areas of western Sichuan.As the dead bodies resulted from unknown cause and varied in amount,it was very unfavorable to the protection and management of the goral and other wild animals in these areas.To find the cause of the goral's death,and corresponding countermeasure,12 times of investigation were conducted in the Dengsheng Managed and Conserved Area from October 2016 to March 2017,21 dead bodies of gorals were found,of which,2 were female,17 were male and 2 were unable to be distinguished,respectively accounting for 9.5%,81.0%,and 9.5% of the total.17 skin samples were collected,and the lab testing showed that sarcoptidae eggs were positive.The death time was mainly in January and February (19 gorals,accounting for 90.5%).All the death places were within 20 meters away from the water points,of which the farthest was 20 meters,the nearest was 1 meter,and the average was 8.5 meters.Bodies were found to be concentrated in the valleys of 2 200 to 2 900 meters above the sea level (18 gorals,accounting for 85.7%,the lowest was 2 165 meters and the highest was 2 910 meters),and the peripheral habitat type was mixed coniferous broad leaved forest.6 bodies were found to be eaten by other animals and 15 were not eaten,accounting for 28.6% and 71.4% respectively.During the investigation,17 bodies were harmlessly disposed,3 skulls and 1 skeleton were collected.The causes of the goral's illness and death were also analyzed and some suggestions were put forward for the management and conservation of gorals.
