According to the IUCN and SANBI Red List Assessments, this subspecies is Critically Endangered as it is a range restricted endemic that is experiencing population decline due to the threat of illegal collection for the specialist succulent horticultural trade (Young & Raimondo 2020; Young 2022). 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 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; 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 subspecies, the minusculum 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 with over-exploitation.

Young, A. 2022. (assessment in prep 2022) Conophytum minusculum subsp. leipoldtii. The IUCN Red List of Threatened Species.
This species has an extent of occurrence of 43 km², is known from several subpopulations and has a population size thought to consist of between 10,000-20,000 mature individuals (Young 2022).
Young, A. 2022. (assessment in prep 2022) Conophytum minusculum subsp. leipoldtii. The IUCN Red List of Threatened Species.
Whole individuals are removed from the wild causing population decline (Young 2022).

High levels of endemism and a restricted range makes this species vulnerable to population loss (Hammer 2002; Young & Desmet 2016; Young & Rodgerson 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)
