loblolly pine trees

Explanation:

Population density refers to the amount of organisms living in a particular area:

            Population density = \frac{number of organisms}{Area}

Area of the forest = 10acres

Population densities of:

  White-tailed deer = \frac{8 white tailed deer}{10acres}

                                 = 0.8white tailed deer/acres

   Coyotes = \frac{7 coyotes}{10acres}= 0.7coyotes/acres

   Armadillos = \frac{45 armadillos}{10acres} = 4.5armadillos/acres

   loblolly pine = \frac{231loblolly pine trees}{10acres} = 23.1loblolly pine trees/acre

The population with the highest density is that of the loblolly pine trees with 23.1 of the trees in an acre.
