Ecosystem Revival Brings Endangered Species Back to China's Northwest
Subei County in northwest China's Gansu Province has become an unexpected sanctuary for rare wildlife, with herds of blue sheep and Argali sheep thriving in its rejuvenated highland ecosystems. Over 50 blue sheep—a species classified as near-threatened—have been observed grazing across mountainous terrain, while more than 20 Argali sheep, the world's largest wild sheep species, navigate the region's alpine grasslands.
The resurgence follows decades of conservation efforts in the Hexi Corridor region, where altitude variations from 3,600 to 5,800 meters create vital habitats. Local authorities attribute the rebound to anti-poaching campaigns, climate-resilient land management, and the establishment of wildlife corridors connecting fragmented habitats.

Ecologists highlight the species' sensitivity to environmental changes, making their population growth a key indicator of ecosystem recovery. "These ungulates require vast, undisturbed spaces and clean water sources," explained conservation biologist Dr. Li Wen. "Their presence confirms that degraded areas can recover with sustained, science-driven interventions.\p>
The trend aligns with broader improvements across western China, where forest coverage in Gansu has increased by 7.4% since 2010 under national ecological security initiatives. Strategically positioned along the ancient Silk Road, the region's ecological restoration also opens opportunities for sustainable ecotourism and biodiversity monitoring technologies.
