According to the SANBI Red List Assessment, this species is Rare as it is a range restricted endemic and not thought to be significantly threatened (van Jaarsveld & Raimondo, 2007). This genus is currently in demand and of popular interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. Several species of the Gasteria genus were among those targeted and confiscated during recent criminal prosecutions of illegal plant collecting (Confiscation Lists (2021) provided by SANParks Sendelingsdrift Botanic Garden and Kirstenbosch Botanical Garden). This species is known to be harvesting to a small extent from the wild for the specialist horticultural trade that has not been noticed to affect the majority of the population (Personal communication, S. Molteno, 5 August 2022). This suggests that this genus may be targeted and that this species can be at risk.
van Jaarsveld, E.J. & Raimondo, D. 2007. Gasteria retusa (Van Jaarsv.) Van Jaarsv. National Assessment: Red List of South African Plants version 2020.1.
This species is known from 4 subpopulations (Personal communication, S. Molteno, 5 August 2022).
Few known subpopulations makes this species vulnerable to population loss. Were exploitation to continue or increase, recruitment and recovery from harvesting may be poor.
