Population
It is estimated that there are at least 600,000 black bears in North America. In the United States, there are estimated to be over 300,000 individuals. However, the Louisiana black bear (Ursus americanus luteolu) and Florida black bear (Ursus americanus floridanus) are threatened subspecies with small populations (see Status/Protection).
Range
The American black bear is distributed throughout North America, from Canada to Mexico and in at least 40 states in the U.S. They historically occupied nearly all of the forested regions of North America, but in the U.S. they are now restricted to the forested areas less densely occupied by humans. In Canada, black bears still inhabit most of their historic range except for the intensively farmed areas of the central plains. In Mexico, black bears were thought to have inhabited the mountainous regions of the northern states but are now limited to a few remnant populations.

The diets of Dall sheep vary from range to range. During summer, food is abundant, and a wide variety of plants is consumed. Winter diet is much more limited and consists primarily of dry, frozen grass and sedge stems available when snow is blown off the winter ranges. Some populations use significant amounts of lichen and moss during winter.

Males live in bands which seldom associate with female groups except during the mating season in late November and early December.

Many Dall sheep populations visit mineral licks during the spring and often travel many miles to eat the soil at these unusual geological formations. As several different bands of sheep meet at mineral licks, ram and ewe groups may mingle and young rams join the ram band which happens to be present at the time. This random contribution of young rams to different ram bands may benefit sheep by maintaining genetic diversity.

Sheep are very loyal to their home ranges. Mineral licks are good spots to observe sheep because the animals are so intent on eating the dirt they pay little attention to humans. However, major disturbances such as low-flying aircraft or operating machinery readily drive sheep from the mineral licks. Photography of Dall sheep is popular for many visitors and residents of Alaska and is not limited by season(alaskaphotographics.com).
