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).
