What caused the deer numbers to crash on the Kaibab Plateau in the 1930s?

Last Updated: 11th June, 2020

In 1970, Graeme Caughley suggested that the mule deer population explosion on the Kaibab Plateau was due more to the recovery of the range than to the disappearance of predators. It turns out that while predators were being removed from the area, so were domestic livestock.

Beside this, why did the population of deer decline drastically in 1925 even though their predators were eliminated?

Created the Grand Canyon National Game Preserve and killed the deers predators. Yes, because they had a drastic incline in the deer population. Why do you suppose the population of the deer declined in 1925 although the predators were being removed? Overpopulation occurred, so the deer starved to death.

Additionally, how was the Kaibab Plateau formed? The Kaibab Limestone, the uppermost layer of rock at Grand Canyon, was formed at the bottom of the ocean. The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down. The way in which the uplift of the Colorado Plateau occurred is puzzling.

Considering this, what was the estimated carrying capacity of the Kaibab Plateau in 1905?

The Kaibab Deer Before 1905, the deer on the Kaibab Plateau were estimated to number about 4000. The average carrying capacity of the range was then estimated to be about 30,000 deer.

What is a Kaibab deer?

The Kaibab Plateau is located in northern Arizona in the United States. The Kaibab deer are particularly important because of the changes in their population during the early 1900s. This particular fluctuation is a great example of population engineering and the effects humans can have on nature.

Why is death by predators more natural?

Answer Expert Verified
It is beneficial because when animals perish to death they suffer and get weaker. if they die by a predator they don't suffer plus its the circle of life, and apart of the food chains. a connection between predators and prey that is good and essential.

What would happen if the deer population decrease?

Fall, hunters harvest surplus animals and reduce population level. Mid-late winter represents the lowest population level due to some deer dying of starvation, predation, and disease. Many factors influence the ability of deer populations to successfully reproduce and maintain a constant population over time.

What happens to population when it reaches carrying capacity?

In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.

In what year did the park rangers begin to reduce the deer's predator populations?

The first step to protect the deer was to ban all hunting. In addition, in 1907, The Forest Service tried to exterminate the predators of the deer.

Was the Grand Canyon an ocean?

An ocean started to return to the Grand Canyon area from the west about 550 million years ago. As its shoreline moved east, the ocean began to concurrently deposit the three formations of the Tonto Group.

What did the Grand Canyon look like millions of years ago?

Around 20 million years ago the Colorado River begins to carve into the Grand Canyon at its eastern end, Marble Canyon, and probably exiting via Kanab Canyon. At 17 million years ago the Colorado Plateau begins to uplift and causes the river to cut deeper.

What was the Grand Canyon like 340 million years ago?

The Grand Canyon's story begins nearly 2 billion years ago when Vishnu basement rocks were formed by intense heat and pressure. Though these rocks are visible down by the Colorado River, the canyon itself didn't really start forming until approximately 70 million years ago.

Is the Grand Canyon getting deeper?

The Grand Canyon is 277 miles long, 18 miles wide at its widest, and more than a mile deep. The river that carved the Grand Canyon is the Colorado River, which is only 100 meters wide. But that's not the end of the story: the Grand Canyon is getting deeper and wider every day.

What made the Grand Canyon?

The general scientific consensus, updated at a 2010 conference, holds that the Colorado River carved the Grand Canyon beginning 5 million to 6 million years ago. Nearly 40 identified rock layers form the Grand Canyon's walls.

How is a canyon formed?

Most canyons were formed by a process of long-time erosion from a plateau or table-land level. The cliffs form because harder rock strata that are resistant to erosion and weathering remain exposed on the valley walls.

How did the Grand Canyon get its name?

John Wesley Powell got the naming rights. Named by Powell, "Its head at the confluence of the Little Colorado River, its foot at the entrance of Nonnow Valley; its length 238 miles." Dellenbaugh writes, "Powell was responsible for most of the names in the Canyon. He called it Grand Canyon on the first trip.

Was Aldo Leopold right about the Kaibab deer herd?

The classic form of the story was often attributed to Aldo Leopold (1943), who reported that reducing the population of predators on the Kaibab Plateau led to an irruption of the deer population, degradation of habitat, and lower carrying capacity for deer.
