Wolverines tend to prefer higher-altitude snowfields, from 9,000 to 12,000 feet.
The males roam large areas, loops of as much as 200 miles, as they search for mates. They are love-’em and leave-’em types.
“They can have a number of mates — three, four or five — within a 60-mile radius,” Carkeet said. “They’re real cads. They knock ’em up and take off.”
That’s assuming they can find females at all. The species isn’t reproducing at a great rate. Carkeet suspects there might be only a few dozen mated pairs in the entire Sierra.
Note the estimated size of the wolverine’s range –200 miles. That’s what the inevitable lawsuit to shut down development in large parts of the Sierra will assert as a marker from which to begin designating the area in which nothing should be disturbed in order to prevent harm to Go Blue and his secretive mates.
