Question

As stem density increases from about 35,000 stems to about 55,000 stems per hectare, what is the increase in snowshoe hare density?

Answer 1

To determine the increase in snowshoe hare density we simply subtract the initial density (in stems / hectare) to the final stem density. That is,
           increase = final density - initial density
Substituting,
           increase = 55,000 - 35,000 
                          = 20,000 stems / hectare
