Askidiosperma andreaeanum has a restricted distribution range, with an extent of occurrence (EOO) of 3648 km². It is threatened by competition from spreading, unmanaged alien invasive plants across its range, but is a fairly common species, known from more than 10 locations. Therefore it nearly meets the criteria threshold for Vulnerable under criterion B. It is listed as Near Threatened.
South African endemic
Provincial distribution
Western Cape
This species is endemic to the mountains of the Western Cape, South Africa, where it occurs mainly from Bain's Kloof to the Franschhoek Mountains, with isolated occurrences in the Riviersonderend, Hex River and Koue Bokkeveld mountains.

It occurs on rocky upper sandstone slopes near streams, sometimes on ridges or shale bands in mountain fynbos.
This species is threatened across most of its range by spreading, uncontrolled alien invasive plants, which have already started to outcompete native species in the Bain's Kloof, Du Toit's Kloof and Franschhoek mountains.

This species is fairly common, and known from 20-30 subpopulations. A continuing population decline is inferred from recent field observations indicating that alien invasive plants are spreading, as well as increasing in density across most of this species' range.
