Gray Wolf. The gray or timber wolf's story is one of the most compelling tales of American wildlife. Once, the wolf was widespread across most of North America, but it was hunted ruthlessly and extirpated over most of its range. Today, the wolf is making a successful comeback in some of its former habitat due to strong conservation efforts.
The gray wolf can range from 60 to 175 pounds and reach a length of 6 feet from muzzle to tail. Because their natural range consisted of most of the Northern Hemisphere, gray wolves are highly adaptable and live in a wide range of habitats.pring and fall temperatures range from mild to severe, 30 to 60 degrees Fahrenheit is common. During the spring, the gray wolf's prey is becoming more active, creating a better chance of a meal for the pack. Breeding occurs during spring, anywhere from January to April depending on how far north the wolves are.
