Mammillaria mercadensis has been assessed as "least concern" by the International Union for Conservation of Nature in 2017. [1] Some species regarded as synonymous with Mammillaria mercadensis by Plants of the World Online have been assessed differently. Mammillaria berkiana was assessed as "vulnerable" in 2009. [4] Mammillaria rettigiana was assessed as "endangered" in 2009. [5] Mammillaria guillauminiana was treated as "data deficient" in 2013, partly because of uncertainty as to its relationship with Mammillaria mercadensis. [6]
