Aloiampelos commixta is a localized endemic to the Cape Peninsula, with an extent of occurrence (EOO) of 68-163 km², and an area of occupancy (AOO) of 44-68 km². It is estimated to occur at three to five locations. The population is currently stable, but it is dependent on ongoing management and clearing of alien invasive plants to avoid its risk of extinction increasing.
South African endemic
Provincial distribution
Western Cape
This species is endemic to the southern Cape Peninsula, where it occurs from Silvermine to the Cape Point section of Table Mountain National Park.
Habitat and Ecology
Major system
Major habitats
Peninsula Sandstone Fynbos
It occurs on rocky sandstone outcrops, 0-600 m.
This species lost some of its habitat to urban expansion in the past, but most of its remaining habitat is now protected in the Table Mountain National Park (TMNP), and development is no longer a significant threat. Most of its range was densely invaded by alien invasive plants in the past, but there has been extensive efforts to clear alien invasive plants inside TMNP. Alien invasive plants require ongoing management and clearing, and re-emergence of invasive species from soil-stored seed banks remain a potential threat. Parts of the Cape Peninsula is being impacted by too frequent fires, which can lead to the local extinctions of reseeder species dependent on seed banks for regeneration. A. commixta is however a resprouter (E. van Jaarsveld pers. comm.) and therefore likely to be resilient to increases in fire frequency.

Recent (2010-2019) field observations recorded several subpopulations on the northern Cape Peninsula. It is not certain whether these are wild populations or not. Within the species' known range on the southern Peninsula, there are at least six subpopulations. The wild populations are healthy and does not appear to be declining (E. van Jaarsveld pers. comm. 2018). The population is suspected to be small, but the estimate of the population size is uncertain. It is possibly smaller than 1000 mature individuals, but field surveys are needed to confirm this.

Most of the population of this species is protected within the Table Mountain National Park.
