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.

Paschim Harmati General Population 2025 is a domesticate landrace cannabis accession. This accession was documented by Isabella in July 2025. A total of 1135 seeds were purchased by Isabella from a local alias 'Ajay'. The seeds come from a cultivated landrace cannabis population of 100+ plants grown near Paschim Harmati. Paschim Harmati is located in Jalpaiguri District, West Bengal, India, within the Maynaguri landrace cannabis growing area of the North Bengal Plains growing region.
Santal people
The Santal (also Santhal; endonym Hor, "human being", or Hor hopon, "children of humankind") are a Munda-speaking Adivasi people of the eastern Indian subcontinent. They are the third most populous Scheduled Tribe in India after the Bhil and the Gond, and the most numerous of the Munda-speaking peoples. The 2011 Census of India recorded 6,570,807 Santals holding Scheduled Tribe status across five states, the largest concentrations being in Jharkhand and West Bengal; further communities live in Bangladesh and Nepal. They speak Santali, the most widely spoken language of the Munda subfamily, written since the early 20th century in the indigenous Ol Chiki script.
The Santal entered the colonial record in the late 18th century as forest-clearing agriculturalists in the Rajmahal Hills, and are remembered above all for the Santal Hul of 1855, one of the largest armed risings against East India Company rule. Their traditional religion, Sarna, centres on the worship of bonga (spirits) at a sacred grove. The Census of India records a majority of Santals as Hindu, a classification disputed by a movement seeking a separate Sarna religious code. Documented Santal practices include ritual, medicinal and material uses of cannabis, treated separately at Cannabis in Santal culture. read more →
