It is an early successional species of disturbed areas in forests in New Zealand and its seeds are light, wind-dispersed and numerous. Seeds germinate in bare patches, and the plant grows quickly, establishing dominance over low-growing vegetation. Plants die out after about 60 years, being replaced by larger, longer living trees. However, in impoverished or wet soils, manuka can become the dominant climax vegetation. Manuka has been seen by generations of New Zealand’s hill country farmers as a serious problem in newly cleared and oversown grassland.
