When we compared the perimeter of male and female tigers across PAs and
non PAs, we found a linear relationship (Fig 6) between the number of
cores and the perimeter. The female tigers in PAs had only one core area
with the expected dramatic increase in number of cores and perimeter
outside PAs (Table 8). This result again supports the finding that
female tigers outside PAs are more prone to conflict owing to their
higher energy demand and greater perimeter which means more chance of
interaction with humans.

to evaluate the chance of human animal encounter for tigers across sex
and protected and non-protected areas in India.
