No construction work has followed the decision, and the issue went largely unnoticed until August, when Trinh Le Nguyen, executive director of the environmental NGO People and Nature Reconciliation (PanNature), began writing about it on Facebook.
In a post dated Aug. 11, Nguyen noted that Tien Hai is part of the broader Red River Delta Biosphere Reserve. Established in 2004, the biosphere reserve spans 137,261 hectares (339,179 acres), including a core area, buffer zone and transition zone across terrestrial and marine areas.
“The core area, the heart of the biosphere reserve, includes Tien Hai Nature Reserve and Xuan Thuy National Park,” Nguyen wrote.

Wildlife trafficking in Vietnam remains complex: report
Wildlife trafficking in Vietnam remains complicated both before and during COVID-19, a report released on June 18 by the People and Nature Reconciliation (PanNature) non-profit organisation showed.
The report was based on a survey carried out across 20 provinces and cities nationwide in 2019-2020.
Vietnam is viewed as a hotspot for transportation and consumption of wildlife products of the world. Despite the Government’s efforts to prevent illegal trade after COVID-19 broke out, the number of violations has yet to decline.
Some wildlife markets are still open and even rare and endangered animals, like turtles and birds, are put up for sale.
Of note, elephant tusk smuggling remains rampant with illegally trading of ivory products found in 27 out of 31 surveyed locations. Many wild animals are kept in cages with poor sanitation, posing risks of spreading diseases.
The report also puts forward measures to minimise the risk of diseases originating from animals, including shutting down all illegal wildlife markets, tightening control of wildlife farms, compiling a list of wild animals allowed for private keeping, and intensifying control of wildlife-related advertising on the mass media and e-commerce platforms, and promoting communications on wildlife trafficking prevention, among others.
