Wildlife of
Gansu Sheng

Primary Threats

• In the Hexi Corridor and oasis belts (e.g., around Dunhuang/Jiuquan-Zhangye-Wuwei), conversion of natural desert-steppe and riparian corridors to irrigated farmland and shelterbelts reduces habitat continuity for gazelles, ground-nesting birds, and desert reptiles; in southern Gansu (Longnan), forest-edge development and small-scale land conversion fragment panda and primate habitat.
• Warming and altered precipitation accelerate glacier and snowpack decline in the Qilian Mountains, shifting runoff timing and reducing late-season water availability for downstream oases; on the Tibetan Plateau margin (Gannan), warmer conditions can drive meadow degradation and wetland shrinkage that affects black-necked crane and other alpine wetland fauna.
• Industrial emissions and urban/industrial wastewater in the Yellow River corridor (including the Lanzhou industrial belt) affect aquatic habitats; localized heavy-metal and tailings contamination risks occur around mining districts, with downstream impacts on riparian vegetation and riverine fish/invertebrates.
• In regulated rivers and reservoirs, non-native fish introductions and aquaculture escapees can alter native fish communities; along disturbed riparian zones and roadsides, invasive weeds can outcompete native steppe/desert plants, reducing forage quality for wild ungulates.
• Disease transmission risks rise where livestock share grazing and water points with wildlife in Gannan and Qilian foothills (e.g., respiratory and parasitic infections), potentially affecting wild ungulates and predators reliant on them.
• Although enforcement has improved, occasional poaching persists in remote mountain and desert areas, targeting ungulates (for meat) and musk deer (for musk), and can depress already small or fragmented populations.
• Illegal collection/trade pressures remain for high-value species or parts (e.g., musk deer products, raptors), and for some reptiles or birds collected opportunistically along transport corridors.
• In parts of the Yellow River system and inland rivers feeding oases, fishing pressure and habitat simplification (channelization/reservoirs) can reduce native fish abundance and age structure, especially near accessible reaches.
• High tourism intensity around iconic Silk Road sites (e.g., Dunhuang/Mogao area) and expanding recreation in mountain scenic zones increase noise, traffic, and off-trail use, disturbing wildlife and concentrating pressure at water sources in arid landscapes.
• In Gannan and Qilian pastoral areas, snow leopard and wolf depredation on livestock can trigger retaliatory killing or poisoning; crop-raiding and property damage by some wildlife near forest edges in southern Gansu can reduce tolerance for conservation.
• Small, isolated subpopulations in fragmented mountain forests (notably in southern Gansu) raise inbreeding and reduced gene flow risks for forest-dependent mammals; barriers such as roads/settlements further limit dispersal.
• Groundwater pumping and upstream water withdrawals to sustain oasis agriculture and cities reduce baseflows and shrink riparian belts/wetlands-critical 'life lines' for biodiversity across the arid Hexi Corridor.
• Highways, rail lines, energy corridors, and expanding wind/solar bases in open steppe/desert landscapes increase habitat fragmentation and collision risk (especially for birds), while new access roads can facilitate human disturbance and illegal take.
• Dams, reservoir operations, and river engineering on the Yellow River and inland basins alter sediment and flow regimes, simplifying channels and disconnecting floodplains; water diversion projects can reduce downstream wetland extent.
• Where irrigation is possible, expansion or intensification of farmland competes directly with natural vegetation for land and water, and increases pesticide/fertilizer runoff risks into river corridors.
• Growth around Lanzhou and other corridor cities increases land take, traffic, and peri-urban pollution; it also concentrates water demand that can intensify ecological water deficits downstream.
• Commercial logging has been substantially curtailed by national programs, but legacy impacts remain in some mountain forests (fragmentation, simplified age structure), and localized illegal cutting can still occur in remote valleys.
• Coal, metal, and industrial mineral extraction in mountain and desert-margin zones can remove/fragment habitat, increase road density, and create dust and tailings risks; careful zoning is especially important near Qilian mountain headwaters and key migration/foraging areas.
