Is rewilding of modern species a good idea? The answer: sometimes

Building off of my previous rant against the idea of pleistocene rewilding I would like to discuss the idea of rewilding modern species. Unlike pleistocene rewilding, which suggests modern descendants of ice age megafauna should be introduced to habitats where their ancestors roamed, modern rewilding involves reintroducing an extirpated species, or at least a closely related subspecies, into an ecosystem which it was known to live in recent times. Probably the greatest example of this would be the reintroduction of wolves to the American west. Since most gray wolf populations were completely eradicated from the lower 48 a closely related subspecies of gray wolf was brought in from Canada to repopulate American parks such as Yellowstone.
Unlike pleistocene rewilding this effort should not upset the ecological balance of habitats these modern species are reintroduced to. These species have evolved in these ecosystems and the ecosystem relies on them for certain services. Continuing with my gray wolf example, in the absence of wolves prey species exploded in population. These increased populations began to destroy their habitats, literally eating themselves out of house and home as there was no predator efficient enough to keep their populations in check. Restoring wolves to these habitats has returned the natural balance. Prey populations have fallen to more natural, sustainable levels and the plant community has begun to rebound.
While I still contend that pleistocene rewilding is a terrible idea, modern rewilding can be beneficial. However, I do not recommend we place modern rewilding as the highest priority. Some areas should strive for this if it is necessary to restore the habitat and there are no greater conservation concerns upon which they should focus. For example, I do not believe India should focus so much of its time and resources on the rewilding of cheetahs when the protection of their tigers and rhinos from poaching should be their highest concern at this time.

Recently a concept known as pleistocene rewilding has arisen within the conservation community. This idea is the cause of great controversy as it suggests we should introduce descendants of extinct pleistocene megafauna to ecosystems where their ancestors once roamed. This would mean releasing species such as lions (Panthera leo), tigers (Panthera tigris), and elephants (Loxodonta africana) into the Great Plains region of North America or bringing a species of rhino into Europe.
While restoring species to an ecosystem in which they, or at least their ancestors, evolved may seem like a good idea at first we must take a closer look at the implications of such an action. These species have been absent from these habitats for thousands of years, most since the end of the last ice age. These systems have continued to evolve without these species. In many places new species have arisen to fill the ecological void left by the extinction of these ancient species. Sure, there are examples of niches which have not been filled (for instance, no predator other than man has found a way to hunt the American pronghorn since the extinction of the American cheetah), but this does not mean we should intervene. More often than not introductions of species do not end well. I of course must cite the example of introduced species such as pythons and kudzu.
Some argue that it was the actions of ancient humans rather than natural selection which pushed these species into extinction. Whether this is true or not it does not justify the introduction of their modern descendants into ecosystems which have adapted to the lack of these pleistocene megafauna. Currently we have greater conservation issues at hand such as deforestation, poaching of rhinos, declining grassland birds, and deterioration of reefs to worry about something frivolous like pleistocene rewilding.
