|Scientific Name:||Pachypodium namaquanum (Wyley ex Harv.) Welw.|
|Red List Category & Criteria:||Lower Risk/near threatened ver 2.3|
|Assessor(s):||Hilton-Taylor, C. <i>et al.</i>|
|Previously published Red List assessments:|
|Range Description:||Found along both sides of the lower Orange River Valley from the Tantalite Valley and Pella mountain range in the east to the Richtersveld, Huib-Hoch and Huns Mountains in the west. It has been recorded from more than 50 localities within an extent of occurrence of approximately 15,000 km².|
Native:Namibia; South Africa (Northern Cape Province)

|Population:||The subpopulations on the Namibian side of the Orange River are inaccessible and therefore generally secure. They are fairly large, with an average density of between 625 and 1,100 individuals per hectare. Similar densities, with a range of ages, are also found on Pella Mt.|
|Habitat and Ecology:||A spiny succulent tree recorded in karroid shrubland.|
|Major Threat(s):||The species has been subjected to much illegal collecting, especially in the Richtersveld, as plants are highly sought-after on both the domestic and international markets. There are further threats from mining activities in Namibia and intense grazing and trampling of the surrounding vegetation by domestic livestock in the Richtersveld. There are also low levels of recruitment in the latter subpopulation, apparently because of insect parasitism of the seeds.|
|Conservation Actions:||Artificially propagated plants are now widely available and the demand for wild-collected plants has effectively been reduced. Richtersveld subpopulation is contained within a national park and provincial nature reserve. The species is also protected by law in both South Africa and Namibia and it is listed in CITES Appendix II.|
