Big trees, little trees -- is there always a correlation with age?

摘要

Big trees are usually older than smaller trees. Although there is some logic to this statement, the premise is not necessarily true. Most hardwood trees regenerate from a disturbance creating even-aged stands. These disturbances could be acts of nature such as tornados, windstorms, fires or catastrophic pest outbreaks or human-caused disturbances such as timber harvesting. Like most agronomic crops, most trees grow best in full sunlight.
