The hard ivory of the African forest elephant makes for more enhanced carving and fetches a higher price on the black market. This preference is evident in Japan, where hard ivory has nearly monopolized the trade for some time. Premium quality bachi, a traditional Japanese plucking tool used for string instruments, is contrived exclusively from African forest elephant tusks. In the impenetrable and often trackless expanses of the rain forests of the Congo Basin, poaching is extremely difficult to detect and track. Levels of off-take, for the most part, are estimated from ivory seizures. The scarcely populated and unprotected forests in Central Africa are most likely becoming increasingly alluring to organized poacher gangs.
