Thanks to effective forest protection and development, particularly large timber plantations meeting FSC standards, Na Hau Nature Reserve in the northern mountainous province of Yen Bai now meets the criteria for exporting carbon credits, promising significant future revenue for the state. 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. 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%. This presents a significant opportunity for the district to expand its forest status database, rehabilitate degraded forests, and move towards forest carbon credit exports.
