Cultivation details

Industrial Crop: Hydrocarbon  Management: Standard  Regional Crop

Humid tropics. Before the introduction of Hevea brasiliensis as the main source of rubber W. coriacea was cultivated in plantations to produce a high quality rubber.

Carbon Farming

  • Industrial Crop: Hydrocarbon  Materials, chemicals and energy include bioplastics, rubber, biomass products gasoline, jet fuel, diesel, butane, propane, biogas. Plants are usually resprouting plants and saps.
  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
