The mountain lion, bobcat, and black bear are also common in other biomes but the other species listed are characteristic inhabitants of the deciduous forest. Seton (1909) estimated original populations of mountain lions and bears at one per 26 sq km (1 per 10 sq mi), and gray foxes at one per 10 sq km (1 per 4 sq mi). Gray squirrel populations vary greatly by time and place, but when common may average + per hectare (

Gray squirrel populations vary greatly by time and place, but when common may average + per hectare (1+ per acre). Chip- munks vary in numbers from year to year, depending on the abundance of nuts and seeds that they can store in their underground burrows to supply them over winter. In beech-maple forests of northern Ohio they average 25 or more per hectare (10 per acre) during the autumnal aspect of good years (Williams 1936). The combined autumn populations of mice and shrews vary from less than 25 per hectare (10 per acre) in poorer forests having little ground humus to ten times as many during good years in a.
