Trees growing on good sites in full light live for up to 100 years, by which age they are about 20 metres or more tall, with a crown diameter of 10 - 12 metres and a bole diameter of 50 - 60 cm[ 299 Title Protabase - Plant Resources of Tropical Africa.

A key timber species throughout its range, yielding a high quality wood. Large stands are known to still occur in places, particularly in protected areas in South Africa, Botswana and Namibia[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ].

The plant is also often grown as an ornamental street and shade tree, being valued especially for its masses of fragrant orange-yellow flowers[ 200 Title The New RHS Dictionary of Gardening. 1992.

In most regions through its range, the species has become less frequent, especially where it is heavily used by local populations[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ]. Across parts of its range the largest and most mature trees are at risk from over exploitation for timber, causing decline in some subpopulations outside of protected areas and sometimes inside protected sites due to both legal and illegal logging activity. In areas of extraction the size structure of subpopulations has become truncated, with smaller trees being much more common than those of larger size, which reduces the amount of seed being produced by the population. There is concern over the impact this might have on regeneration at some sites. Further investigation is needed to establish the extent to which this threatens the future viability of the species. Despite these threats to the species a large population of Pterocarpus angolensis is likely to remain across its range as not all trees are exploitable due to defects or being small in size. The species also has a large extent of occurrence. The persistence of the species in a suffrutex stage and its ability to colonise exposed landscapes are also to its benefit. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2018)[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ].
