Traditionally, wildlife conservation efforts have concentrated on the
establishment of national parks and reserves. Additional strategies ar
e needed if we are to conserve more than a small proportion of tile wo
rld's natural habitats and their wildlife. One such strategy is the ap
plication of wildlife conservation regulations by private land owners
on their properties. This paper uses examples of ranches in the season
ally flooded Ilanos of Venezuela to evaluate if effective wildlife con
servation can coexist with sustainable wildlife use and cattle product
ion. Income estimates derived from cattle production data varied among
ranches from $US7.1 to $US26.4 per ha, while estimates of potential a
dditional income through regulated capybara Hydrochaeris hydrochaeris
and caiman Caiman crocodilus exploitation ranged up to $US7.7 per ha.
The economic benefits of capybara and caiman harvests can be realized
only by protecting wildlife habitat. Thus, it is suggested that large
ranches in the Ilanos can play a major role in wildlife conservation a
s well as provide economic gains for those involved. Common denominato
rs for success are: personal involvement of owners, effective patrolli
ng systems, co-operation of neighbouring ranchers in patrolling activi
ties, and ranches being located far from densely populated areas. For
tile programmes to succeed in the long term, government and conservati
on agencies will need to give Ii-lore support to landowners.
