OBJECTIVES: 1. to produce a line graph using data on the Kaibab deer population of Arizona from 1905~1939 . The deer population would've most likely stayed around 4,000 because the overgrazing had reduced the food source to support the deer. Albumin values are in agreement with albumin values for mule deer in the Southwest. Hunting was reopened, and during the fall of 1924, 675 deer were killed by hunters.

Today the Arizona Game commission carefully manages the Kaibab … The average carrying capacity of the land was unknown, in part because this concept was not widely used by naturalists at the time. A) maximum sustainable population size that a given environment can support, E) include the effects of disease, predators, and food on a single species within a community. However, these deer represented only one-tenth the number of deer that had been born that spring. However, these deer represented only one-tenth the number of deer that had been born that spring. By 1923, the deer were reported to be on the verge of starvation and the range conditions were described as "deplorable." Without the well-meaning interference of humans, what do you think would have happened to the deer population after 1900? Hunting permits are issued to keep the deer in . D) indicates the relative numbers of individuals of different ages within a population. Assuming the populations are of equal size, the length of time necessary for significant divergence to take place in the populations depends on ________. Today, the Arizona Game Commission carefully manages the Kaibab area with regulations geared to specific local needs. The average carrying capacity of the range was then estimated to be about 30,000 deer. The major force(s) causing the genetic divergence of the two isolated squirrel populations is/are ________.

Graph the size of the Kaibab deer population of Arizona from 1905 to 1939. Partially funded by the Arizona Game and Fish Department and the Arizona Deer Association, examination of herd By 1923, the deer were close to starvation and the area conditions were horrible. Deer Population from 1905 to 1924 Year 1910 1915 1920 1924 Deer population 4 000 9 000 25 000 65 000 10 000 A Kaibab Deer Investigating Committee recom- mended that all livestock not owned by local resi- dents be removed immediately from the range and that the number of deer be cut in half as quickly as possible. 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. This number was never confirmed by any kind of count or survey, and has become an accepted number mainly because no other estimate is available. Determine the carrying capacity of the Kaibab Plateau . A population's age structure generally ________. Place time on the X axis and "number of deer" on the Y axis 2. The overgrazing reduced food to support a carrying capacity of 30,000, when the herd grew to 100,000 it kept reducing food supply. 3.1 Significance of the Kaibab Deer; 4 See also; 5 References; 6 External links; Physiography. * Graph data on the Kaibab deer population of Arizona from 1905 to 1939 ...

Do you think any changes had occurred in the carrying capacity of the range from 1900 to 1940? What future management plan would you suggest for the Kaibab deer herd? Yes, it decreased because in the beginning the forest was overgrazed. By 1923, the deer were reported to be on the verge of starvation and the range conditions were described as "deplorable." The average carrying capacity of the range was then estimated to be about 30,000 deer. The Forest Service reduced the number of livestock grazing permits. Why do you suppose the population of the deer declined in 1925 although the predators were being removed? Today the Arizona Game Commission carefully manages the Kaibab area with regulations geared to specific local needs. Physiography. The Arizona Strip and Kaibab Plateau have long been hailed as the world’s premier areas to hunt for trophy mule deer and boast an impressive track record of producing giant mule deer bucks for the hunters that are lucky enough to draw tags in these world famous trophy mule deer hunting areas. Signs that the deer population was out of control began to appear as early as 1920 - the range was beginning to deteriorate rapidly. 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). Kaibab Plateau Visitor Center Hwy. However, the story disappeared from texts in the late 20th century after several papers noted uncertainties in estimations of the deer population and provided alternative explanations. Taught land managers that there is a fine balance that must be managed between carrying capacity, food, source, climate, hunting and/or predators. I suggest that the agreed values become a standard for mule deer in the Southwestern U.S. As excess dietary N is converted to a caloric resource, a continual state of under-nutrition exists for the deer upon entering the N. Kaibab winter range. 90% or more of the trophy mule deer bucks that live on the Kaibab Plateau spend their summers in the cooler high country areas.
