Many landowners plant pines with the intention of harvesting them at some point in the future. When pulpwood markets are favorable, a complete stand harvest within 15 to 20 years is possible and may bring an acceptable return. However, longer rotations can bring higher financial returns on larger diameter trees if landowners are willing to begin thinning their pine stands when trees are 10 to 15 years old. Thinning is a partial tree harvest in an immature stand to maintain or accelerate diameter growth of the remaining trees. If it is done properly, thinning can bring substantially higher revenues when trees are harvested at 25 to 40 or more years of age.

Height—diameter and height—age relationships are also investigated.

Longleaf pine is the longest-lived of the southern pine species. Individual longleaf pines can reach years in age with trees in excess of years old documented. To reach that point of old age the life history of longleaf pine can be described in several stages. Longleaf pine seeds are high in fats and are thus highly prized by seed predators like mice, birds, squirrels, and ants.

Large trees, especially those with mind-boggling heights and diameters, raise the question of age. Is a normal pine tree life span even long enough for trees to grow to such amazing sizes? Unless someone knows when a tree was planted, finding the age of a tree must be measured using direct or indirect methods. Tree ring samples are taken using an increment borer to drill and remove a core sample from the tree. The growth rings of the core sample can then be counted.
