The outstanding result was summarized at the conference held on Tuesday morning on Cat Ba’s langur conservation project from 2019 through 2023. The project was approved by the Hai Phong City People's Committee in 2019 and sponsored by Germany’s Leipzig Zoo in coordination with Vietnamese partner agencies. To date, there are 82 Cat Ba growing langurs in Cat Ba National Park. Cat Ba langur population increases on average by 3% per year. The conservation of Cat Ba langur, held with a community-based motto, helps the project bring initial positive results, contributing to conserving the overall biodiversity of Cat Ba National Park–a world biosphere reserve, as well as increasing values of the World Natural Heritage Ha Long Bay–Cat Ba Archipelago./.
