Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): Mining of the granite outcrops is the main threat for Tacinga braunii. Destruction of the surrounding caatinga for agricultural activities (crops and cattle ranching) pose an additional threat to the species. African pasture grasses (Brachiaria ssp., Pennisetum ssp., Bromus ssp.) are planted in the area for cattle fodder, and this is also affecting the populations.

Conservation Actions [top]

Conservation Actions: The species is propagated ex situ. It is not found in any protected areas.
