adj. (of a forest) having mature trees that have developed naturally over a long period without significant disturbance.
n. a forest or stand of trees characterized by such maturity and ecological complexity.
The term "old-growth" combines "old" (from Old English eald, meaning "aged" or "long-standing") and "growth" (from Old English grōwan, meaning "to grow"). It emerged in the late 19th to early 20th century in forestry contexts to describe ecosystems with ancient, undisturbed trees. The word reflects a focus on natural longevity and ecological continuity, contrasting with managed or secondary forests.
