There is
an urgent need to develop well-defined
strategies for the long-term
conservation of chimpanzees and gorillas
in the Congo Basin. The Goualougo
Triangle Ape Project is a site-based
conservation and research program that
employs both traditional and innovative
research methods to conduct applied
research that addresses important issues
related to the conservation of ape
populations and their habitats
Apes and Logging.
A significant
number of remaining chimpanzee and
gorilla populations in Western
Equatorial Africa reside in active
timber concessions, many of which
are within areas identified as being
exceptional for the conservation of
these apes. The conservation outlook
of these endangered apes would
improve significantly if forestry
companies were prepared to make a
few changes to management policies
in
logging
concessions. One of the Goualougo
Triangle Ape Project's main
scientific objectives is to document
the effects of logging operations on
apes in northern Congo and use this
information to develop and evaluate
recommendations to reduce the impact
of timber extraction on chimpanzees
and gorillas.
We have
outlined specific recommendations
for reducing the impact of
commercial logging on wild apes,
many of which can be implemented
within the framework of sustainable,
reduced-impact logging at little or
no additional cost. These include:
* Collaborating
with Conservation Scientists
* Identifying
Important Ape Food Trees for
Protection
* Establishing
Ape Population Monitoring Programme,
* Establishing
Buffer Zones around Protected Areas
Counting Apes.
Recent reports
have shown that central chimpanzee (Pan
troglodytes troglodytes) and
western lowland gorilla (Gorilla
gorilla gorilla) populations in
central Africa are rapidly declining
due to disease epidemics, commercial
bushmeat
hunting,
and habitat destruction. The extent
of these declines may never be known
because precise baseline ape density
estimates are not available from
most central African forests. Even
when abundance estimates are
available, the survey methods have
been criticized as biased, limited
in their ability to detect trends,
and lacking causal inference. These
methods must be refined and precise
ape density estimates obtained to
ensure strategic and appropriate
conservation planning that would
permit the survival of remaining
chimpanzee and gorilla populations
in central Africa.
Satellite Imagery Analysis.
Remote sensing
is proving to be a critical tool for
assessing and monitoring forests and
wildlife in the Congo Basin.
Collaborating with scientists from
the Woods Hole Research Center, we
recently used satellite imagery to
compare ape habitats in the
Nouabal-Ndoki National Park and
Odzala National Park which are both
located in northern Republic of
Congo. Continuing our effort to
better understand ape distribution
and habitat use in northern Congo,
we are working with Dr. Eric
Lonsdorf of the Urban Wildlife
Institute at Lincoln Park Zoo to
identify the distribution of
preferred habitats for chimpanzees
and gorillas over a large spatial
and monitor the effects of
mechanized
logging
on the apes.
Preserving
Fragile Cultures.
Our knowledge
of the variation in chimpanzee tool
using behavior has continuously
expanded with insights from
long-term research sites and
initiation of new field studies of
wild chimpanzees populations.
However, more than 50% of the range
of chimpanzees in Western Equatorial
Africa is currently allocated to
logging concessions which is more
than double the area of their range
encompassed by protected areas
(17%). Commercial
logging
in northern Congo began at a
relatively low intensity in the
1970?s, primarily focusing on
extraction of mahogany (Entandrophragma
sp.). However, advances in forestry
technology and changes in timber
product market values over the last
ten years have tripled the number of
tree species in northern Congo that
are attractive to the international
market. Dr. Carel van Schaik has
proposed that local extinction,
hunting
pressure,
selective
logging,
and habitat loss affect the
transmission process of the
traditional behaviors of wild great
apes. This means that we are in a
race against time to document and
protect chimpanzee cultures in the
Congo Basin.
