The Western Himalayas is a major landrace cannabis cultivation region spanning the mountain valleys of northern India, encompassing traditional charas (hand-rubbed hashish) producing areas in Himachal Pradesh, Uttarakhand, and parts of Jammu and Kashmir.

The Western Himalayas growing region is characterized by landrace cannabis cultivation in steep valley systems between 500 and 3,500 meters elevation.

The region's cannabis populations are cultivated primarily for charas production, with hand-rubbing techniques passed through generations of farming communities.

-===Topography===
+== Named Populations and Varieties ==
-The Western Himalayas growing region occupies the middle-elevation montane zone of the [[Himalayas|Himalayan range]], primarily within the watersheds of major river systems including the [[Beas River|Beas]], [[Tons River|Tons]], and [[Alaknanda River|Alaknanda]] rivers. The region is sandwiched between the [[Pir Panjal Range]] to the west, the [[Great Himalayan Range]] to the north, and transitions to the [[Eastern Himalayas]] at approximately 80°E longitude.<ref name="Singh2005">Singh, S.P. & Singh, V. (2005). "Vegetation of the Himalaya". ''Mountain Research and Development''.</ref>
-Cannabis cultivation occurs primarily in:
+== Cultural and Ethnic Context ==
-* River valley floors (1,500–2,200 m)
-* Mid-slope terraced fields (2,200–2,800 m)
-* High valley settlements (2,800–3,500 m)
-==Climate==
+=== Cultural-Ethnic Distinctions ===
-The region experiences a temperate montane climate with distinct seasonal patterns:
-'''Summer Monsoon''' (June–September): Heavy precipitation from the [[Indian monsoon]], with annual rainfall ranging from 1,500mm in rain-shadow valleys to over 3,000mm in exposed slopes. Cannabis vegetative growth peaks during this period.<ref name="Negi2012">Negi, V.S. et al. (2012). "Plant diversity and vegetation in relation to altitude in the high altitude cold desert of Lahaul-Spiti, Himachal Pradesh". ''Journal of Mountain Science''.</ref>
+==Geography==
-'''Autumn''' (October–November): Cooler temperatures (10–20°C) trigger flowering. Traditional harvest timing varies by valley and elevation, with communities timing collection based on resin maturity indicators.
+===Topography===
-'''Winter''' (December–March): Heavy snowfall above 2,500m, with temperatures dropping below freezing. Traditional seed selection and storage occurs during this period.
+==Climate==
-'''Spring''' (April–May): Snowmelt and warming temperatures. Traditional planting season for most growing areas.

 ===Regional Traits===
-Western Himalayas cannabis populations generally exhibit:
-* '''Growth habit''': Medium to tall stature (2–4m), branching structure adapted to slope conditions
+===Geographic Variation===
-* '''Leaf morphology''': Narrow to medium-width leaflets, often with serrated margins
-* '''Flowering time''': October flowering typical for mid-elevations, earlier at higher elevations
-* '''Resin production''': Abundant trichome development, selected for hand-rubbing quality
-* '''Adaptation''': Cold tolerance, monsoon humidity resistance, short growing season adaptation
-===Valley-Specific Variation===
+===Other Variations===
-Significant morphological and chemical variation exists between valley systems, likely reflecting:
-* Local selection pressures and traditional preferences
-* Geographic isolation between watersheds
-* Elevation and microclimate differences
-* Centuries of farmer selection
 ==Current Cultivation Practices==
 ===Traditional Methods===
-Traditional cultivation in the Western Himalayas involves:
-'''Land Preparation''': Terraced slope fields, often integrated with other crops (apples, beans, gourds, peas, maize)
-'''Planting''': Direct seeding in spring (April–May) after last frost, or transplanting from nursery beds
-'''Cultivation''': Minimal, natural input systems, relying on monsoon rainfall and natural soil fertility. Some use of urea and other chemicals noted in certain districts.
-'''Harvest''': Hand-rubbing of live flowering plants to collect resin (charas production), seed collection for next season
-'''Processing''': Traditional hand-rubbing techniques vary by valley, with specific methods passed down informally among peers. Some valleys, like Malana and Parvati in particular also process water extracted hash, gas extracts, tinctures and other crude extractions. There are at least two rosin presses in the Parvati and Malana valleys.
-===Modern Pressures===
-Contemporary cultivation faces multiple challenges:
-* Enforcement activities and eradication programs
-* Introduction of high-THC hybrid varieties
-* Climate change impacts on traditional cultivation calendars
-* Out-migration of youth from mountain villages
-* Loss of traditional knowledge
 ==Conservation Status==
 ===Threats to Landrace Populations===
-'''Primary Threats''':
-* '''Genetic contamination''': Introduction of commercial hybrid varieties leading to outcrossing with landraces
-* '''Eradication campaigns''': Government programs targeting cultivation areas
-* '''Habitat loss''': Development pressure in accessible valleys
-* '''Climate change''': Shifting precipitation patterns, changing snowpack timing
-* '''Knowledge erosion''': Loss of traditional cultivation knowledge as youth migrate
-'''Conservation Priority''': The Western Himalayas is considered '''vulnerable''' due to ongoing genetic contamination and enforcement pressures, despite continued cultivation in many areas. Urgent documentation and ''in situ'' conservation efforts are needed.
 ===Conservation Efforts===
-Current conservation activities include:
-* Field documentation of remaining landrace populations
-* Seed banking and ''ex situ'' preservation
-* Community-based conservation initiatives
-* Traditional knowledge documentation
-* Genetic characterization studies
 ==Chemical Profile==
 ===Cannabinoid Content===
-Western Himalayas populations are traditionally drug-type cannabis, selected for resin production. Preliminary chemotype studies indicate:
+Western Himalayas populations are traditionally drug-type cannabis, selected for resin production. Research is needed to characterize chemical profiles.
-* '''THC content''': Moderate to high (typically 8–18% in dried resin)
-* '''CBD content''': Low to moderate (often 0.5–3%)
-* '''Terpene profile''': Complex profiles varying by valley, commonly featuring myrcene, pinene, and caryophyllene
-Further research is needed to characterize valley-specific chemical profiles and their relationship to traditional quality assessments.
