Structural diversity and regeneration of the endangered Prunus africana (Rosaceae) in Zimbabwe

BACKGROUND

Prunus Africana is widely recognized for its medicinal purposes resulting in high unsustainable use and selling in the international market. Its bark contains many healing properties. Overexploitation has led to its listing in CITES list of endangered species. A remnant population is still available at the Eastern Highlands of Zimbabwe however, the area is prone to land use changes.

RESEARCH GOALS AND METHODS

To assess size class distribution, intraspecific competition and the regeneration of P. Africana, diameter at breast height and heights are calculated across the three study sites, Chirinda Forest (forest reserve), Cashel Valley (Estate) and Nyanga National Park.

CONCLUSIONS AND TAKEAWAYS

According to the authors, trees at Chirinda which is a forest reserve, an area with the highest protection has larger diameters and heights compared to those in Estates and National Parks. Poor regeneration in all the sites is attributed to little light penetrating the forest floor. The results of this study will aid policy formulation and conservation of P. africana in Zimbabwe.
