dc.description.abstract |
Pterocarpus angolensis is a tree species that is extensively used
for its medicinal bark and good quality wood in South Africa. Its demand
has resulted in some local extinctions in distribution area, leaving very
few viable populations in natural areas. The current study was looked
at the status of a pristine population located in the Lowveld National
Botanical Garden, Mpumalanga Province, South Africa. Data on population
parameters such as basal stem circumferences, plant height, and crown
health estimates were collected from 16 transects of 100 m x 5 m. Results
showed a healthy population that displayed an inverse J-shaped curve as
analysed from some of the parameters sampled. More individuals found
within the 0-50 cm stem circumference size class is an indication of a
population with a healthy base for recruitment. Most of trees were in the
6.1-8.0 m height class which is a sign of a population with a good number
of individuals in fruits bearing stage. High levels of canopy damage are
an area of concern, since it impacts on the vigour of the population. It
is concluded that this is a healthy population of P. angolensis, which
could serve as a source of propagules in re-forestation programmes. It is
recommended that the population be closely monitored for any signs of
human disturbance, which would negatively influence its health. |
