Question 1099743: Animal population densities are important to those who manage wildlife. This is particularly true when animals pose risks to humans. Managing the population of grizzly bears in Yellowstone National Park is one example. Grizzly bears roam Yellowstone Park, which is 3,472 square miles. Additionally, the bears roam a surrounding area that is 40% as large as Yellowstone. Although their territories overlap considerably, each bear needs at least 10 square miles to himself/herself to call home (US Geological Survey, 2011).
Calculate the total available land in and around Yellowstone for grizzly bears to roam. Round to the nearest square mile.

Estimate the maximum number of bears that can be supported on the available land.

If there are about 3 adult female bears for every 2 adult male bears, then approximately how many male bears can be supported in and around Yellowstone Park? How many female bears?
males bears
female bears

According to the condition, the area of Yellowstone National Park is 3472 square miles.
Surrounding area is 40% of it, i.e. 0.4*3472 = 1389 square miles (approximately).
So, the total habitat area is 3472 + 1389 = 4861 square miles.
Leaving 10 square miles for each bear, we allow = 486 bears in the area.
Of them, are adult males: = 194 adult males.
The other are adult females: = 291 adult females.
The difference 486 - (194 + 291) = 1 is an UNCERTAINTY of my calculations.
