A selected set of wild herbivores on Lewa Wildlife Conservancy
(LWC) and Ol Pejeta Ranch were evaluated for
their utility value by productivity indexing based on a
computer bio-economic model, Prying Livestock Productivity
(PRY). PRY derives productivity of species based on
feed energy efficiency (FEE). The respective FEE indices
(Kenya shillings, Ksh, per kilogram dry matter, Ksh kg )1
DM) for consumptive use only on LWC and Ol Pejeta
Ranch for zebra, buffalo, impala, giraffe and eland were
9.23 and 9.20; 4.70 and 4.74; 4.05 and 3.42; 7.34 and
7.24; 6.21 and 6.06. With non-consumptive use included
in productivity assessments on LWC and Ol Pejeta Ranch,
the respective indices for zebra, buffalo, impala, giraffe and
eland were 15.52 and 9.98; 21.10 and 6.34; 9.85 and
4.69; 14.41 and 9.92; 12.72 and 16.05. The buffalo and
eland were the most productive species on LWC and Ol
Pejeta Ranch respectively, while the impala was the least
productive on the two units.Most herbivores on LWC were
more productive than the same species on Ol Pejeta Ranch
when touristic value was included in the indexing. However,
without tourism, species in the two units had similar
index values, except for the impala. It was concluded that
tourism provides the main economic justification for utilization
and conservation of the herbivores.
