Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.

A 30-year-old commercial pine tree grown in good conditions in Arkansas will be about 0.3 m (1 ft) in diameter and about 20 m (66 ft) high. After 50 years, the same tree will be about 0.5 m ( 1 + 1 ⁄ 2 ft) in diameter and 25 m (82 ft) high, and its wood will be worth about seven times as much as the 30-year-old tree.
The female cone then opens, releasing the seeds which grow to a young seedling. To fertilize the ovum, the male cone releases pollen that is carried in the wind to the female cone. This is pollination. (Male and female cones usually occur on the same plant.) The pollen fertilizes the female gamete (located in the female cone).
