Ds. Wilkie et al., MODELING THE SUSTAINABILITY OF SUBSISTENCE FARMING AND HUNTING IN THEITURI FOREST OF ZAIRE, Conservation biology, 12(1), 1998, pp. 137-147
We used empirical data to simulate the impacts, over the next 40 years
, of subsistence-level agricultural clearing and bushmeat consumption
on forest resources within the recently established Okapi Wildlife Res
erve in northeastern Zaire. Satellite imagery, human population census
data, and field measurements were used to calculate Present and proje
cted impacts of agricultural clearing on forest cove: Data on per capi
ta meat consumption and the species captured by hunters were combined
with relevant ecological data to estimate ratios of consumption to pro
duction and to assess the sustainability of hunting. Even with project
ed population growth of nearly 300% among local communities over 40 ye
ars, sufficient secondary forest is available that agricultural cleari
ng will have minimal effect on mature forest throughout most of the re
serve. Impacts on the reserve's fauna will be more dramatic particular
ly within 15 km of villages where most hunting currently occurs Subsis
tence exploitation of forest antelopes may be sustainable in much of t
he reserve (especially if high estimates of game production are used),
but as the human Population continues to increase duikers will likely
be over-hunted. Primate populations do not appear to be threatened In
the near future in those areas where bow hunters exploit monkeys, but
an increase in this specialized activity in other legions of the rese
rve and growing human populations could change this. Although addition
al surveys of commonly hunted species throughout the Okapi wildlife Re
serve are essential to enhancing the precision of the simulation, our
results suggest that mitigation efforts should he designed and impleme
nted note if the long-term effects of domestic bushmeat consumption ar
e to be addressed.
