WebFeb 24, 2024 · The mean tree density across the sample sites is 10,750 trees/ha. Saunders suggests that self-seeded tea trees grow in densities of over 10,000 stems/ha, from comparing collected datasets. Natural thinning occurs within the stand over time as trees compete for light and other resources .
