Trees often have very long life spans (some live for more than 3,000 years). Many types of pine trees exist throughout the world, and while most of them have similar life spans, some live significantly longer than others.
More than 100 species of pine trees exist, constituting about one-third of all evergreen trees in the world. They grow throughout the northern hemisphere, from parts of Mexico to the Arctic Circle.
The reproductive structures of pine trees are housed in the cones that grow on the tree. Foraging animals and wind spread pine seeds throughout the environment, where they germinate when certain environmental conditions are met.
Most types of pine trees, such as Virginia pines, white pines, shortleaf pines and table mountain pines, have a life spans of 100 to 200 years. Some species, such as the bristlecone pine, can live for thousands of years.
