The Na Hau Nature Reserve in Van Yen district, Yen Bai province, spans 16,950 hectares of core area and nearly 10,000 hectares of buffer zone, housing a rich ecosystem of flora and fauna. The preservation efforts of the Mong community have kept these primeval forests lush and green. For the local people, the forest is a lifeline, ensuring their well-being and happiness. To protect the forest, the Mong community in Na Hau has maintained various customs, such as the New Year forest worship ceremony, to educate and promote forest planting, care, and protection. Beyond the Na Hau Nature Reserve, Van Yen district has nearly 94,000 hectares of forest, including almost 40,000 hectares of natural forest and over 54,000 hectares of planted forest, with a forest cover rate exceeding 67%.
