At 2,967 tigers, India’s capacity at peak

With reserves
crowded, animals
are venturing out
A detailed survey released
on Tuesday reveals that
nearly a third of India’s tigers
are living outside tiger reserves and nearly 17 of the 50
reserves are approaching the
peak of their capacity at sustaining their populations. India hosts 70% of the world’s
tigers.
At 2,967, experts say, India
may slowly be approaching
its peak carrying capacity of
tigers. For the first time, said
a scientist associated with
the survey, there was an attempt to segregate how many tigers were largely present within the reserves and
how many flitted in and out
and were dependent on the
core reserve for sustenance.
This was to guide conservation policy.
The reserves, by definition, are a “source” and suitable for nourishing a growing tiger population because of prey availability and territory. However, when they get
too crowded, tigers venture
out further from “sources”
and form “sinks” and much
of wildlife population dynamics is about understanding this sourcesink relationship. “Generally, there’s a
6040 split in tigers from
sourcesink, but this can vary. However, we are approaching the maximum capacity of several good
reserves, and the focus
should be on developing underutilised reserves and not
overnourish those that have
a good population,” said Rajesh Gopal, secretary general, Global Tiger Forum.
