The Megafauna We Have is the Megafauna We'll HaveWhile there are exceptions, the days of large importation of megafauna is largely behind us. While there will still be some swaps between continents, most SSPs should act as if the genes they have now are all they will ever have. If we operate with this assumption that there will be no imports (likely true in many cases), it paints a potentially grim picture for the future of many popular species in zoos. However, this future doesn't necessarily need to be this way with enough dedicated individuals properly planning population management along with institutions dedicated to breeding the species consistently. Of course there will always be an element of luck involved that can't be controlled. However, I'd take my chances with luck in a well-managed population way more than I would in a poorly managed one, and as we are seeing with many phase out species today, poor management can have detrimental effects on a population. By viewing the management and breeding as the important element of ensuring demographically healthy populations, I am acknowledging that in most cases which species continue to be kept, and which are phased out, is in direct control of those in charge, both at the association level and at specific zoos.
It is important to acknowledge, however, that by assuming no imports will occur, we are setting up a scenario in which a phase out becomes a permanent, irreversible decision (it usually is). While I am not one to lose sleep over an obscure species of antelope or bird being phased out, and neither is the general public, we face a reality where it is important to acknowledge that even some charismatic megafauna may become completely unavailable to zoos in the future if management of their respective programs don't improve. While there are some species I am very confident will be around in fifty years (e.g., African lions, lowland gorillas), there are many more that I am less than confident in. Some of the charismatic megafauna that I believe have rather uncertain futures in US zoos, and are dependent on the dedication of facilities and management, include: polar bears, Andean bears, sloth bears, jaguars, African and Asian elephants, Masai giraffes, okapi, bonobos, white-cheeked gibbons, spotted hyenas, African wild dogs, Eastern black rhinos, and Malayan tapirs. While all of these species have strong potential of being present in zoos in fifty years, all of them also are at risk of extinction in zoos unless managed properly. As sad as a future without these species in zoos may be, it goes to show how important proper management of populations and perfecting breeding techniques are.
I would add that intercontinental transfers remain a possibility, even if the imports of wild megafauna have largely ceased.
I would give a few recent examples : 2 Indian Rhinos have been sent from Beauval and La Flèche (France) to Guadalajara (Mexico) ; the recent imports of Brown Hyaenas from South African facilities in Europe (Germany and UK) ; I have many other examples from my "home zoo" Beauval, even if they aren't true megafauna species (Yellow Backed Duikers imported from the US, Harpy Eagles from Itaipu breeding center in Brazil...).
In exceptional cases there have been imports of wild animals from other continents, even if they are strictly regulated. I would mention a few years ago the import of wild Patagonian Pumas by Vincennes (France), these animals being captured in farms and unable to release in the wild without raising conflicts.
