Scientists identify centuries-old tea forest on Vietnam’s Ta Dung peak

A scientific survey led by experts from the Institute of Biotechnology and Environment and Tay Nguyen University recorded 117 specimens across seven native Camellia species in the core zone of the park's primary forest. 

The ancient tea trees are distributed at elevations ranging from 1,000 to 1,980 meters above sea level.

The study is part of a broader project to catalog indigenous tea varieties in the area.

Among the recorded trees, at least 17 are believed to be over a century old. 

The oldest, a Camellia furfuracea (known locally as "che cam"), is estimated to be 123 years old. 

Other notable species include Camellia sinensis (green tea), Camellia kissii, and Camellia bidoupensis.

Researchers say the ancient tea trees are not only of botanical value but also show promise for medicinal use. 

The plants were found to contain high levels of polyphenols, flavonoids, and saponins—compounds known for their antioxidant, antimicrobial, and blood sugar-regulating properties.

However, due to exposure to harsh natural conditions for over a century, several trees have begun to exhibit signs of internal decay. 

The research team has called for conservation efforts, including studies on growth patterns and longevity, to preserve what they describe as a "biological treasure."

"This research highlights the biodiversity value of Ta Dung National Park and offers opportunities for eco-tourism, medicinal plant development, and sustainable conservation," said Khuong Thanh Long, director of the park.

Ta Dung National Park spans more than 20,000 hectares, nearly half of which is primary forest. 

Known for its year-round mist and remote landscapes, the area has become a popular trekking destination in Vietnam's Central Highlands.
