Yes in regards to polar bears and yes in regards to many other species. Considering the threats that polar bears face in the wild, the difficulty breeding them, and their proximity, it would be understandable for zoos to import rescued bears to try and establish a successful breeding program. It would not take be too difficult to transport the bears from Alaska, Canada, or Greenland. If I can recall correctly, all of the SDZ's zoos are rescues and a zoo in Texas just got a rescued polar bear cub. If zoos were to get permits to take polar bears from the wild, they would have to take precautions to make sure the most endangered individuals are taken. (i.e.: stranded cubs vs. adults in conflict due to human expansion)
As for other animals, the Endangered Species Act was to prevent individuals from importing endangered or threatened animals. Although, regulated institutions accredited by the AZA should be given permission to import these species or better preference in the permit-process to import species they really need faster. Historically zoos have taken animals from the wild to the point of devastating their wild populations, so zoos would have to take animals from the wild with the burden of proof that those individuals aid to conservation efforts that benefit to the species. Parts of the article seem that the actions of group of representatives go toward other species other than polar bears. Hopefully this will help speed the permitting of Indian gharials for importation into their SSP.
