Introduction:
The environment may be changed by biotic factors as well as by relationships between organisms and the physical (abiotic) environment. The carrying capacity of an ecosystem is the maximum number of organisms that an area can support on a sustained or continuing basis. The population density (number of individuals per unit area) may produce such profound changes in the environment that the environment becomes unsuitable for the continued survival of that species. Humans can also interfere with natural interactions of species with their environments with either positive, negative, or neutral effects. This activity will show how these some of these human interactions influenced a population of deer in Arizona.
In 1905, the deer population on the Kaibab Plateau in Arizona was estimated to be about 4,000 on 300,000 hectares of range. The average carrying capacity of the range was estimated to be about 30,000 deer. On
