Vegetation is more abundant around the edges of the Takla Makan Desert primarily because these peripheral areas are where sand dunes meet river valleys and deltas, allowing groundwater to lie comparatively close to the surface.1

In the vast, arid interior of the desert, thick strata of moving sands and extreme water scarcity prevent the widespread growth of plants. However, the desert's edges benefit from the presence of water sources, such as the Tarim River and its branches, which support a more diverse range of flora. In these zones, one can find species characteristic of river valleys, including:12

Turanga poplar
Oleaster
Camel thorn
Saltworts
Members of the Zygophyllaceae (caltrop) family1

Additionally, these areas often feature shrublike vegetation, stunted trees, and dense growths of willows, sea buckthorn, Indian hemp, and Ural licorice. This availability of water is the fundamental factor that distinguishes the more fertile edges from the nearly barren, sand-covered interior.213
