90% of wild chimpanzees are dead

A census of West African chimpanzees living in Côte d'Ivoire shows
that 90% have died, according to researchers from the Max Planck
Institute for Evolutionary Anthropology. Deforestation, farming,
poaching and wars have made it harder for chimps to find protected
places to live. The few chimpanzees left are widely scattered with
only one substantial group left living in Taï National Park.

"The human population in Cote d'Ivoire has increased nearly 50 percent
over the last 18 years," explains Christophe Boesch, PhD, director of
the primatology department of the Max Planck Institute. "Since most
threats to chimpanzee populations are derived from human activities
such as hunting and deforestation, this has contributed to the
dramatic decline in chimpanzee populations. Furthermore, the situation
has deteriorated even more with the start of the civil war in 2002,
since all surveillance ceased in the protected areas."

In the 1960s Côte d'Ivoire was home to about 100,000 chimpanzees. By
the late 1980s, this had shrunk to about 10,000. While that already
represented a drastic decrease, it nonetheless meant that Côte
d'Ivoire contained about half of the world's remaining West African
chimpanzee populations.
The last refuge for the disappearing West African chimpanzees is Taï
National Park. However, this population is at risk from poachers,
warns Dr. Boesch. External financial support in that park is scheduled
to end in 2010, a change that will probably have disastrous
consequences for the last vestiges of chimpanzees in Côte d'Ivoire
unless further financial aid can be secured.
