The scientists, like the Indian high court, call for more "sizable buffer zones" around such parks. They also recommend creating connections between reserve areas such as the Great Limpopo Transfrontier Park in southern Africa. Another such proposal would build a string of connected reserves down the spine of the Americas or begin to connect tiger reserves in India.
In addition, the authors also call for efforts to engage and benefit local communities—much as tiger tourism has created an industry wherever the endangered cats linger in India. Without a solution that better manages such reserves to reconcile the often competing needs of humanity and our fellow inhabitants of the planet, like the tiger, even these lands set aside as natural zoos may find themselves haunted by ghosts of species past.
