Mammillaria plumosa grows on limestone cliffs in sparse xerophytic shrubland, there is continuing decline due to ongoing collection, but the number of locations probably exceeds ten and the population is not likely to be severely fragmented. The species is illegally collected for the ornamental trade. The local community in the area also collects plants from the wild and sells them at local markets at Christmas time, as they are used to decorate nativity scenes.
