Using the Infrared Camera to Investigate Animal Diversity in Jiuzhaigou National Nature Reserve

From May 2014 to April 2015,the survey of bird and mammal diversity was conducted by using the infrared trigger automatic camera in Jiuzhaigou National Nature Reserve.Set infrared-cameras were set in 30 location,Altogether 2 832 photos were taken in 3 153 working days.There were 525 independent photographs (IP) which could be identified,among them 161 were bird IP,356 were mammal IP and 8 were disturbed IP from human activities and livestock grazing.We have identified 13 species of birds (belonging to 6 families and 2 orders) and 16 species of mammals (belonging to 9 families and 3 orders).of which 11 species were listed in Chinese National Key Protected Wild Animal Species.For mammals,Elaphodus cephalophus,Capricornis milneedwardii,Naemorhedus griseus,Tamiops swinhoei and Budorcas taxicolor topped the ratings,and yellow-bellied weasel(Mustela kathiah) was a newly recorded species found in this survey.For birds,Turdus rubrocanus,Crossoptilon auritum,Trochalopteron elliotii,Parus monticolus and Ithaginis cruentus topped the ratings.In the mean while,it was found that the species of ungulates such as Capricornis milneedwardii and Naemorhedus griseus were suffering from sarcoptidosis.It's necessary for the Reserve to take measures to monitor and control the disease.Besides,the discussion was made on some frequent problems in the application of infrared camera technology to the monitoring of the natural reserve.
