From Industrial Scar to Biodiversity Haven - A Tianjin Success Story

The Qilihai Wetland in Tianjin's Ninghe district is a stunning example of ecological restoration, especially during the summer months. The area is characterized by expansive reed beds and is home to numerous milu deer and oriental storks. This wetland serves as a vital "green lung" for the Beijing-Tianjin-Hebei region and is recognized as one of the world's ancient coastal wetlands.

Prior to its restoration, the area suffered from industrial pollution. However, an eight-year ecological restoration project has transformed the landscape into a biodiverse haven. Before 2017, the area was fragmented by numerous small factories and fish ponds, which limited bird sightings.

To address the ecological degradation, Ninghe initiated a series of major restoration projects, investing a significant amount of resources and converting a large area of land back into wetland. The positive impacts of this restoration are evident in the improved air quality, with a significantly higher concentration of negative oxygen ions compared to urban areas, and a reduction in PM2.5 levels.

The restoration efforts have led to a remarkable increase in biodiversity. The number of bird species has grown substantially, and the wetland has become a major migration site. The integrity, biodiversity, and ecological safety of the wetland have significantly improved, earning Tianjin recognition as a UNESCO Biodiversity Charm City.

Qilihai, as the only national-level conservation area in China that combines ancient coast and wetlands, is becoming a crucial habitat for rare species. The milu deer, once extinct in the wild, have been reintroduced to the area and are thriving.

The milu deer are now freely residing in the wetland meadows, demonstrating the ecosystem's ability to support top-tier species. The presence of numerous bird species further reflects the ecological improvements.

Advanced technology, including drone patrols and artificial intelligence recognition systems, is used to monitor and protect the wetland. These technologies have significantly improved efficiency and reduced the alert rate for illegal activities.

The ecological improvements have also benefited local agriculture and tourism. The sweet potatoes produced in the area have a unique flavor, and crabs have become a popular attraction. The number of birds living in Ninghe has exceeded the district's population, serving as an ecological benchmark.

The wetland's monitoring center provides real-time data on the core zone, using drones, AI systems, and infrared cameras to monitor the flora and fauna. The restoration of Qilihai is a testament to the era of harmonious coexistence between humans and nature.
