Look at the blank graph on page 2. Notice the X and Y axis. In 2018, the U.S. Geological Survey assembled a Corridor Mapping Team to provide technical assistance to western states working to map bison, elk, moose, mule deer, and pronghorn corridors using existing GPS data. Removal or adjustment of the limiting factor would result in a population that is capable of reaching a new, presumably higher, threshold. Removal or adjustment of the limiting factor would result in a popula-tion that is capable of reaching a new, presumably higher, threshold. Arizona Game and Fish Department, 2020, Migration Corridors of Mule Deer in the Kaibab North Herd in Arizona in Kauffman, M.J., Copeland, H.E., Cole, E., Cuzzocreo, M., Dewey, S., Fattebert, J., Gagnon, J., Gelzer, E., Graves, T.A., Hersey, K., Kaiser, R., Meacham, J., Merkle, J., Middleton, A., Nunez, T., Oates, B., Olson, D., Olson, L., Sawyer, H., Schroeder, C., Sprague, S., Steingisser, A., and Thonhoff, M., 2020, Ungulate Migrations of the Western United States, Volume 1: U.S. Geological Survey data release, https://doi.org/10.5066/P9O2YM6I. The deer population would've most likely stayed around 4,000 because the overgrazing had reduced the food source to support the deer. For deer to survive they need food, water, shelter/cover, and space to move about and find their daily requirements. • Predators could only harm deer. The Scientific Argument and activity cover population ecology concepts including carrying capacity and limiting factors.

Deer were nearly hunted to extinction by the early 1900s and were extirpated in many regions. 4. The Ungulate Migrations of the Western United States report and associated map archive provides the means for corridors to be taken into account by state and federal transportation officials, land and wildlife managers, planners, and other conservationists working to maintain big game corridors in the western states. Winter nutrition is recognized as a key limiting factor for mule deer. See below. Heady (1975:116) observes: "In these instances, the limiting factor seemed to be only one — the food supply. On November 28th, 1906, As a result, the deer population was well below its carrying capacity of 30,000. PROCEDURE: Before 1905, there were approximately 4,000 deer on almost 30,000 hectares of land on the Kaibab Plateau in Arizona. Analyze the factors that caused the changes in the deer population. The deer population would've most likely stayed around 4,000 because the overgrazing had reduced the food source to support the deer. Some of these interactions may be direct and others will be indirect. Graph data on the Kaibab deer population of Arizona from 1905-1939.   Privacy Kaibab Deer Population Lab Answer Key Kaibab Deer Lab Answer Key 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. The Kaibab Plateau is bound on the east, south, and west by vertical canyon walls which run along the Colorado River and Kanab Creek. BIological Survey estimated the whitetail population at 300,000. Graph data on the Kaibab deer population of Arizona from 1905 to 1939. In this populations lesson plan, students investigate the causes of changing populations of the Kaibab deer and they find the carrying capacity of the Kaibab Plateau. Define the term limiting factor. Across the western U.S., many ungulate herds must migrate seasonally to access resources and avoid harsh winter conditions. Course Hero, Inc. The Kaibab North Deer herd winters among pinyon-juniper, sagebrush, and cliffrose landscapes along the west, east, and northern extents of the plateau. A limiting factor that depends on population size is a Density-dependent limiting factor. Their summer range consists of habitat dominated by ponderosa pine, mixed conifer, and aspen. Let’s read the introduction and objectives. Give examples of limiting factor for the deer in our activity. Portions of the Kaibab [...]. Unfortunately, the Kaibab forest area had already been overgrazed by livestock and predator populations were firmly established. (For reference, the field in Tiger’s Hollow is about 1 hectare.) Water availability throughout seasonal ranges may be the limiting factor for this population. For instance, overgrazing of land may make the land unable to support the grazing of animals that lived there. The Y-axis is in thousands. Determine factors responsible for the changing populations. Alternatively, a limiting factor is defi ned as the single factor that prevents popu-lations from increasing beyond a threshold. This provides a sample graph from the provided data, plus answers to the analysis questions. This report compiles two research efforts, the first completed by Arizona Game and Fish Department in 2014, and the second from Utah Division of Wildlife’s ongoing research started in 2017. Graph data on the Kaibab deer population of Arizona from 1905-1939. It will consume other plants and plants are living. It may mate with other deer. Taught land managers that there is a fine balance that must be managed between carrying capacity, food, source, climate, hunting and/or predators. The grass is mandatory for when deer need something to eat. Materials: pencil. 3) Determine the carrying capacity of the Kaibab Plateau Background Information: The environment may be altered by forces When limiting factors are in excess it may lead to a reduction in population levels. • Deer populations were stable over time and could be easily managed by the manipulation of any limiting factor: food, water, cover, predation. These data provide the location of migration routes for Mule Deer (Odocoileus hemionus) in the Kaibab North Herd in Arizona. The Kaibab has many different types of organisms and populations within the area, three of, them being deer, grass, and predators such as mountain lions.
