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.
