Over the years, increased development in the area affected the tigers' habitat, and it was thought that by 1998 there were only six to nine wild Siberian tigers living in the ______ region. However, a ____ on development put in place in 2015 resulted in a ______ population increase of the species, and now the area is thought to have about 35 tigers and 70 leopards. The problem, however, was that the old park was too small to support further population increases. Always ___________, Siberian tigers and leopards need large areas to hunt for food.
