|Current Population Trend:||Stable|
|Habitat and Ecology:||Usually in dry and moist thicket and savanna-type vegetation. This species is used to feed cattle and is widely used as a hedge plant. The latex is used sometimes as a fish poison, and at one time was exploited, although not very successfully, in the production of rubber. The latex apparently has too high a resin content.|
|Major Threat(s):||This species is used to feed cattle and is widely used as a hedge plant. The latex is used sometimes as a fish poison and at one time was exploited, although not very successfully, in the production of rubber, however, the latex apparently has too high a resin content. Other threats faced are habitat degradation and clearing by fire for charcoal harvesting.|
|Conservation Actions:||Occurs in a large number of protected areas. Listed under CITES Appendix II.|
|Amended reason:||Replaced Old Threat Scheme code OLD 1 Habitat Loss/Degradation (human induced) with new Threat Scheme code 5.2.1. Biological resource use -> Gathering terrestrial plants -> Intentional use (species is the target). Also updated the threats description section to include it's use as a cattle feed and hedge plant and the exploitation of the plants latex as a fish poison and it's use in production of rubber.|
