Plateau pika (Ochotona curzoniae, hereafter pika) is a key species in the alpine grasslands on Qinghai-Tibetan (QTP). They are susceptible to influence of external disturbance and may present great variation, which important evaluate their ecological role grasslands. However, our knowledge regarding interannual variation influencing mechanism still limited due lack long-term observation density. This study aimed investigate spatiotemporal variations associated factors by aerial photographing at 181 sites Gannan Tibetan Autonomous Prefecture 2016, 2019, 2022. Our findings showed that: (1) primarily distributed central northeastern Maqu County southwestern part Luqu County, average density was range 9.87 ha−1 14.43 from 2016 2022; (2) high were found 1.22 3.61 °C for annual mean temperature, 12.86 15.06 diurnal temperature range, 3400 3800 m DEM less than 3° slope; (3) varied response changes precipitation driest month different years. results concluded that significant variations, climate terrain variables dominantly affected Given fluctuation responses these variables, suggested monitoring crucial reveal real distribution, habitat environment, Moreover, unmanned vehicles cost-effective tools pika.
