Uebelmannia buiningii is on the verge of extinction. It is affected by illegal collection of plants and seeds, fire, and cattle trampling. The population has been fragmented into a number of tiny subpopulations. Some subpopulations, including the type locality, have been collected to the point of extirpation. The overall range of the species is very limited (extent of occurrence is 40 km²).

Population [top]

Population:Some of the subpopulations of this species, including at the type locality, have disappeared. The remaining subpopulations consist of only a few individuals. According to Braun and Esteves Pereira (1988) and Schulz and Machado (2000) Uebelmannia buiningii is on the verge of extinction and is scarcely if at all in cultivation, where it has proved very difficult.
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Yes
Population severely fragmented:Yes
Continuing decline in subpopulations:Yes

Habitat and Ecology [top]

Habitat and Ecology:This species south-eastern campo rupestre (Serra Negra) element grows on slabs of quartzitic rock amongst gravel (Taylor and Zappi 2004).
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The species is collected as an ornamental from the wild. This activity is a major threat.

Threats [top]

Major Threat(s): The major threat for this species is illegal collection. Uebelmannia buiningii is practically extinct in the wild and rare in cultivation, it has been indiscriminately collected (plants and seeds) and is threatened by fires and nomadic grazing.

Conservation Actions [top]

Conservation Actions: The species is listed in CITES Appendix I. It does not occur in any protected areas.
