According to the IUCN Red List Assessment, this subspecies is Critically Endangered as it 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). As plants confiscated by the authorities in South Africa have only been identified to species level all the subspecies are treated the same here and are therefore believed to have been collected illegally. Collecting pressure is likely to increase in the future as the number of species and volume of plants targeted within the genus since 2019 has increased (Young, 2022). As of 2019, this genus has become popular in trade and there is a high demand from international 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; Young, 2020). Plants of this genus were among those targeted and confiscated during recent criminal prosecutions of illegal plant collecting (Majikela, 2020; Myburgh, 2021). There has been several recorded confiscations of the truncatum species and others of the genus from illegal plant collection (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) This suggests that this genus and species is being targeted and that this subspecies may be threatened.

Young, A. 2022. (assessment in prep 2022) Conophytum truncatum subsp. viridicatum. The IUCN Red List of Threatened Species.
This taxon has an extent of occurrence of 7280 km² with a estimated population size of more than 100,000 mature individuals (Young, 2022). The population is expected to decline by less than 25% over the next three generations (Young, 2022).

Young, A. 2022. (assessment in prep 2022) Conophytum truncatum subsp. viridicatum. The IUCN Red List of Threatened Species.
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)
