Featured Growing Regions

Northeastern Thailand

Southeast Asia - Khorat Plateau

The Khorat Plateau NLD landrace corridor retains core Thai-stick genetics, but diversity is eroding rapidly; conservation and documentation are urgently needed.

Endangered {{#if:| {{{GrowingArea}}} | } 100+ accessions

→ View region

Northern Laos

Southeast Asia - Lao Highlands

Rugged northern Lao highlands with NLD-type landraces still in cultivation, but under intense pressure; documentation and conservation are urgent.

Critical {{#if:| {{{GrowingArea}}} | } 9 accessions

→ View region

Western Himalayas

South Asia - Western Himalayas

Charas heartland where high-elevation, village-managed NLD landraces persist despite tourism and law-enforcement pressure—resilient yet not invulnerable.

We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge—preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.
