This is part of the complete camera trap data collected in KNR from 2010 to 2013. Camera traps were set at several watering points to observe the water uses of Przewalski's horse and Asiatic wild ass.

Przewalski's horse and Asiatic wild ass may have coexisted in the Dzungarian Gobi. The horse's reintroduction in the Kalamaili National Reserve offers a chance to assess this potential.We studied the water needs and usage of these two equids through experiments and camera traps, considering environmental conditions, human presence, and their interactions.The equids showed different water needs. The horse needed more water, especially during temperature rises, and used fixed watering points. In contrast, asses can tolerate saline and near-depleted waters, and visited the waters at different times.Asses can deplete waters overnight during hot, dry summers. This forces horses to seek water near human settlements, which asses avoid. These human-associated waters serve as refuges against competitive exclusion by asses.Human presence allows sympatric coexistence of the two equids in the Dzungarian Gobi, preventing asses from excluding horses from desert habitats.
