1.
age of a tree
The number of years a tree has lived, typically measured from the time it was planted or sprouted. In Japanese, 樹齢 is used exclusively for trees, not for people or animals, and often appears in descriptions of old, famous, or protected trees.
Composed of 樹 (tree) and 齢 (age). A formal compound used in botany, forestry, and in references to notable old trees at temples, shrines, and parks. The age is usually stated with 約 (approximately) because older trees' ages are estimated, often by counting annual growth rings or by historical records.
