Northeastern Thailand
The Khorat Plateau NLD landrace corridor retains core Thai-stick genetics, but diversity is eroding rapidly; conservation and documentation are urgently needed.
Endangered 55 accessions
Northern Laos
Rugged northern Lao highlands with NLD-type landraces still in cultivation, but under intense pressure; documentation and conservation are urgent.
Critical 3 accessions
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.

Herbarium Amboinense (1690)
The Herbarium Amboinense (Dutch: Het Amboinsche Kruid-boek) is a six-volume botanical catalogue of the plants of Ambon Island in the Maluku Islands of Indonesia, composed by the German-born naturalist Georg Eberhard Rumphius (1627–1702) during his service with the Dutch East India Company (VOC). Edited by Johannes Burman, it was published posthumously in Amsterdam between 1741 and 1750, describing approximately 1,200 species. The botanist E.M. Beekman has described the work as foundational to the study of Moluccan flora.
Chapter XXXIV of Volume 5 (pages 208–211, with Plate LXXVII) contains a detailed account of cannabis in the eastern Indonesian archipelago, including descriptions of three forms of the plant, multiple preparation methods, medicinal uses and the Malay concept of Hayal. The chapter uses the name Cannabis indica for the Ambon plant, a designation that predates Lamarck's formal taxonomic description of Cannabis indica in 1785. read more →
