Population biology of elaeodendron transvaalense jacq. in the presence of harvesting

Abstract

Elaeodendron transvaalense Jacq. is one of the medicinal plant species commonly used by people in the Venda region. Te species is known to treat a variety of diseases. It is widely used and important to traditional healers. Because of this, it found its way into the muthi markets, and it is among the seven most commonly traded plant species in the Venda region. Tis study investigated the impact of bark harvesting on the population structure of this species. Te study revealed that although the level of bark harvesting is high, the species is able to resist that stress since it is a fne-grained species. Te population also showed the ability to regenerate as it exhibited an inverse J-shaped curve. Te crown health status was generally good although some individuals, contributing 9% of the sample, had dead crowns, which are a cause for concern. A linear relationship was noticed between areas harvested and stem circumference, which is understandable considering the large surface area of harvestable bark on bigger individuals.
