Despite conversation efforts, some scientists admit that the species is probably extinct in the wildlife apart from the specimens held in captivity. No sighting of wild wolves of Hudson have been recorded in the last few years.

Conservation programs and recovery plan for wolves in captivity are implemented by zoos and other conservation groups to preserve the biological diversity and participate in its reintroduction.
