There are an estimated 11,025 trees of species a in an area of 3,150 hectares. what is the population density of the tree species? the population density of the trees is _ per hectare.

Population density is the average number of organisms that make up a population per unit area or unit volume.

As given in the question; Number of organism (trees of species A) = 11,025 and land area = 3,150 hectares.  

Population Density = Number of organism / Land Area = 11025/3150= 3.5 trees/hectare.

Therefore, the population density of the trees is 3.5 trees per hectare.
