Abstract:

Aims: Understanding the activity patterns, range, and suitable habitat distribution of Equus hemionus is essential for assessing its survival strategies in response to environmental changes.

Methods: In this study, we used camera trapping to survey water resource utilization patterns of Equus hemionus during summer season (June to August) from 2021 to 2023 in Kalamaili National Park candidate area. Meanwhile, we studied the kernel activity range of six rescue released Equus hemionus fitted with GPS satellite collars, tracking them from 2022 to 2024 in Kalamaili National Park candidate area. Finally, we combined camera trapping and GPS satellite data, and used the BIOMOD2 model to assess the suitable habitat distribution of species during the summer season, and evaluated the conservation gap within national park candidate area.

Results: The results showed that: (1) we obtained 5,996 independent detections of Equus hemionus at water resource during summer season. Among them, 2,825 independent-detections were recorded during the daytime, 2,212 in the nighttime, 459 in the morning and 500 at nightfall. (2) Equus hemionus exhibited random usage of water sites at nighttime (wi= 1.32), daytime (wi= 0.94), morning (wi= 0.98) and nightfall (wi= 1.07) in different time periods; the activity index at nighttime was slightly higher than in other three periods, with a peak activity period occurring between 23:00 and 04:00, while activity levels were relatively lower during the morning and nightfall periods; (3) the 50% kernel activity range was 4.98-162.18 km2, with a mean of 76.34 ± 69.36 km2; the 95% kernel activity range was 27.67-2,117.72 km2 with a mean of 892.95 ± 908.91 km2; (4) based on BIOMOD2 models, the suitable habitat area for Equus hemionus in Kalamaili National Park candidate area during summer was 1.94 × 104 km2, with 76.97% of the suitable habitat within national park candidate area boundaries.

Conclusion: Our study has preliminarily obtained the water resource utilization patterns, activity range and suitable habitat distribution of Equus hemionus in Kalamaili National Park candidate area. These findings enrich our understanding of behavioral ecology, and provide a scientific basis for developing conservation measures to protect the endangered species and their habitats in national park candidate area.
