We have been particularly successful in the use of entomopathogenic
agents of viral origin in nettle caterpillars and the breeding of barn
owls as natural predators of rats.
We have been using barn owls as a bio-control for rats at PT SIMP in
Riau since 1997. The current owl population at PT SIMP in Riau has
achieved total rat control for the entire oil palm plantation covering
approximately 57,000 hectares, and no rodenticide has been used
for more than 10 years in this region.
We started another barn owl development project at PT SIMP’s South
Sumatra estates where 507 nest boxes were installed and 3,574 young
birds were raised between 2008 and May 2013. With our positive
experience in Riau and South Sumatra, we hope to replicate the success
of the barn owl development projects on our other plantations, with
the ultimate goal of achieving zero rodenticide usage. Special permit
is required from the government before we can ship the barn owls to
other islands outside Sumatra.
Note: The data is based on our RSPO estates and as such covers 35% of our total oil palm
estate hectares.
