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). Collecting pressure is likely to increase in the future as this species is highly sought after by collectors, is difficult to cultivate 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 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/or confiscated during recent criminal prosecutions of illegal plant collecting (Majikela, 2020; Myburgh, 2021). There has been recorded confiscations of the uviforme species and rauhii subspecies amongst 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). Rare Conophytum species remain potentially threatened by collecting (Young et al. 2015). 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 uviforme subsp. rauhii. The IUCN Red List of Threatened Species.
This taxon has an extent of occurrence of 11 km², is known from 3 locations with a population size thought to consist of no more than 5,000 mature individuals (Young, 2022). Almost 3,000 mature individuals have been removed from habitat between 2019-2021 with more likely to have been harvested but not intercepted (Young, 2022).
Young, A. 2022. (assessment in prep 2022)Conophytum uviforme subsp. rauhii. The IUCN Red List of Threatened Species.
Whole individuals are recorded in confiscations.
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)
