]. 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)[

It is used for construction, carpentry, high class furniture manufacture (tables, chairs, benches), parquet flooring and veneer, and in South Africa and Namibia particularly for wood carving (bowls, spoons and walking sticks). Due to its flexibility, resistance and light weight it is also useful for boats, doors and windows[

Propagation

Seed - although trees can produce ample seed (up to 10,000 fruits/ha are recorded), germination is poor. Under natural conditions only 2% of the seed germinates and half of the seedlings produced die in the first year[
