What do you want to bet that the “Mount Graham red squirrels” are the same as any other squirrel but renamed that to make them extinct. That is the game they play.
The Mount Graham subspecies has been isolated from other subspecies of red squirrels since the end of the Pleistocene glacial periods. It is still rather unclear if the Mt. Graham red squirrel is distinct or not from red squirrels elsewhere. Studies on genetic data are in progress.

About two years ago my wife was building a new bridge over a slough in Colusa County, California, and during the pre-construction conference at the site she was informed by a fish and game biologist that she would have to take steps to protect the “endangered” ‘Giant’ garter snake.
At the time, a garter snake happened to slither by the group, and she stepped over and picked it up, and asked is this a ‘Giant’ garter snake?
The biologist replied that they could only tell by counting the number of scales that encircled the head behind the plate. She began to count the scales while asking how many a ‘Giant’ garter snake had, and the biologist answered “I don’t know.”
She then tossed the snake and asked “how then do we know which snakes to protect, and how do we protect them?”
The puke didn’t have any answer.
