Wild boars are found in the river-valley thickets near the Takla Makan Desert because these peripheral regions provide the necessary water and vegetation that are otherwise extremely sparse or absent in the desert interior.1

While the vast majority of the Takla Makan is devoid of plant cover, the areas where sand dunes meet river valleys and deltas feature groundwater that lies comparatively close to the surface. This environment supports a richer variety of flora, such as poplar, oleaster, and various shrubs, which create the dense thickets that serve as a suitable habitat for wild boars. In contrast, the desert's interior is largely inhospitable, with animal life restricted primarily to these more hospitable, vegetated fringes.1
