The Deer Population A field study was conducted to observe a deer population in a given region over time. The deer were counted at different intervals over a period of 40 years. During this period of time both ranching and hunting increased in the study region. A summary of the data is presented in the table.

Questions on Deer Population During which 10 year period did the greatest increase in the deer population occur? State one possible action that could have been used to help maintain a more stable population of deer in the area. Identify an abiotic limiting factor for the deer populations. Identify a biotic limiting factor for the deer populations. List two problems an overpopulation of deer can cause in the environment.
