There are about 0.0002 grizzly bear per acre.
There are about 0.009 elk per acre.
There about 0.001 mule deer per acre.
there are about 0.0001 bighorn sheep per acre.
Population density is the total number of persons that are living in a population per unit area.
Mathematically, population density can be calculated by using this formula:
Population density = Population size/land area
Population density = Number of animals/Area of Yellowstone National Park
For the number of grizzly bear, we have;
Population density = 445/2220000
Population density = 0.0002 grizzly bear per acre.
For the number of elk, we have;
Population density = 20,000/2220000
Population density = 0.009 elk per acre.
For the number of mule deer, we have;
Population density = 2400/2220000
Population density = 0.001 mule deer per acre.
For the number of bighorn sheep, we have;
Population density = 260/2220000
Population density = 0.0001 bighorn sheep per acre.
