The Trees that Bleed

Rosewood is one of the most trafficked wild commodities on earth. When it's cut it bleeds a blood red sap. Having exhausted stocks elsewhere, Chinese traders have turned to West Africa.

And yet, we can reveal they are been logged and smuggled at an alarming rate - from Senegalese forests, through to the port of neighbouring Gambia and all the way onto China.
