Threats
Massive declines in the population
of this species are presumably occurring in the face of habitat loss.
Huge areas of lowland forest were removed from its range during the 20th
century, chiefly through logging, conversion to agriculture and fire.
For example, Kalimatan lost almost 25% of its cover between 1985 and
1997, and
Sumatra
lost 30% in the
same period, suggesting that virtually all original lowland habitat will
have disappeared from these areas by around 2010, unless preventative
measures can be implemented effectively. A similar scenario faces all
other range states. Major fires in
Borneo
and
Sumatra
continue to affect enormous areas of forest while
industrial-scale illegal logging is rampant in almost all areas. A
secondary threat is imposed by widespread high levels of hunting.
