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.
