Population data:The last complete population survey in the area was completed in 1965. During this extensive survey, 35 coyotes were calculated in the valley. Since then, USFWS scientists have checked dens each winter to count pups and collected any carcasses found throughout the year. These have been summed into five year periods and can be used to represent births and deaths within the population. The population size for each subsequent time period can be found by taking the current population, subtracting the deaths and adding the births.

Provide a neatly labeled digital graph created in Google Sheets or Microsoft Excel of population sizes versus time. Population sizes will first need to be calculated as described above.
