The average carrying capacity of the range was then estimated to be about 30,000 deer. Determine the carrying capacity of the Kaibab Plateau. The average carrying capacity of the land was unknown, in part because this concept was not widely used by naturalists at the time. • To determine the carrying capacity of the Kaibab Plateau before 1905 and after 1930. Determine factors responsible for the changing populations. On November 28th, 1906, President Theodore Roosevelt created the Grand Canyon National Game Preserve to protect the "finest deer herd in … This activity asks students to graph the number of Kaibab deer on the plateau after predators were removed. The The average carrying capacity of the range was First, the tall grasses that the deer fed off of were severely overgrazed by sheep, cattle, and horses. Graph data on the Kaibab deer population of Arizona from 1905 to 1939; Determine factors responsible for the changing populations; Determine the carrying capacity of the Kaibab Plateau; Background. • To graph data concerning the deer population of the Kaibab Plateau from 1905 to 1939. Scientists estimated the total average carrying capacity of the Kaibab plateau was about 30,000 deer. Background. In 1905, the deer population on the Kaibab Plateau in Arizona was estimated to be only about 4,000 deer, even though carrying capacity of the range was estimated to be about 30,000 deer. Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. In 1905, the mule deer population on the Kaibab Plateau in Arizona was estimated to be about 4,000 individuals on 300,000 hectares of vegetated land (or range). The United States Forest Reservists considered the need to protect deer on a 300,000-hectare range of the plateau as the studies at the time revealed that the population significantly declined to slightly below 5,000 deer. • Graph data on the Kaibab deer population of Arizona from 1905 to 1939 • Determine factors responsible for the changing populations • Determine the carrying capacity of the Kaibab Plateau Background Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. The plateau’s pre-1905 population of deer was estimated to be around 4,000. Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. At the beginning of the 20th century, the Kaibab Plateau was witness to an interesting experiment in what some might call population engineering. Scientists estimated the total average carrying capacity of the Kaibab plateau was about 30,000 deer. • Graph data on the Kaibab deer population of Arizona from 1905 to 1939 • Determine factors responsible for the changing populations • Determine the carrying capacity of the Kaibab Plateau Background Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. There were so few Kaibab deer for two reasons. Population Dynamics of the Kaibab Deer Objectives: x To graph data concerning the deer population of the Kaibab Plateau from 1905 to 1939. x To determine the carrying capacity of the Kaibab Plateau before 1905 and after 1930. x To determine the factors responsible for the fluctuating deer population. In 1905, the mule deer population on the Kaibab Plateau in Arizona was estimated to be about 4,000 individuals on 300,000 hectares of vegetated land (or range). The average The plateau's pre-1905 population of mule deer was estimated to be around 4,000. Arizona’s Kaibab Plateau had a carrying capacity of 30,000 animals as at 1905 (Allen, 2013). Graph data on the Kaibab deer population of Arizona from 1905 to 1939 Determine factors responsible for the changing populations Determine the carrying capacity of the Kaibab Plateau Background Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. Graph data on the Kaibab deer population of Arizona from 1905 to 1939. • To link the story of the Kaibab deer to human population growth and carrying capacity. • To determine the factors responsible for the fluctuating deer population.
