According to the IUCN Red List Assessment, this species is Critically Endangered as it is a range-restricted endemic with few known locations that is experiencing population decline due to the threat of illegal collection of mature individuals for the international trade in ornamental succulents as well as by anthropogenic climate change (Young, 2022). Collecting pressure is likely to increase in the future as this species is highly sought after by collectors as well as their being an increase in the number of species and volume of plants targeted within the genus since 2019 (Young, 2022). As of 2019, this genus has become popular in trade and there is a high demand from international and domestic horticultural markets for wild collected plants as indicated by media, police reports and several online marketplace, e-commerce, and auction sites (Friedman 2021; Tshuma 2021; Trenchard 2021; Hyman 2020). Plants of this genus were among those targeted and confiscated during recent criminal prosecutions of illegal plant collecting (Ramatseba 2021; Majikela 2020; Myburgh 2021) (Confiscation Lists (2019-2021) provided by Cape Nature, SANBI Karoo Desert National Botanical Garden, SANBI Kirstenbosch Botanical Garden, SANParks Sendelingsdrift Botanic Garden and the Department of Forestry, Fisheries and the Environment). Although there is no evidence for the collection of this subspecies at present, it is evident the species and genus is being targeted and may be threatened with over-collection.

This taxon has an extent of occurrence of 184 km² from five sites with a population size thought to consist of less than 7,500 mature individuals (Young, 2022).
Young, A. 2022. (assessment in prep 2022) Conophytum roodiae subsp. corrugatum. The IUCN Red List of Threatened Species.
Individuals are removed from the wild causing population decline (Young, 2022).

This species has a restricted range which makes it vulnerable to population loss (Hammer 2002; Young & Desmet 2016). Regeneration potential for the vast majority of the Conophytum genus is very poor as recruitment is low and dependent on successive, appropriate weather conditions. Seeds are not known to disperse. Regeneration will take decades. (Young, personal communication 2021, 5 October)
