Agathosma aemula is range-restricted species (extent of occurrence 54 km²) with no severe threats, and therefore it is not suspected to be in danger of extinction. It is therefore listed under the IUCN 3.1 Criteria, globally, as Least Concern but is nationally categorised as Rare.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range

Habitat and Ecology
Major system
Terrestrial
Major habitats
Cederberg Sandstone Fynbos
Description
It is localized to seeps on gentle sandstone slopes.
Threats
This species has no severe threats. As a reseeder, it is potentially impacted by too frequent fires, however, it is relatively fast growing, and therefore is only likely to be affected by very short fire cycles, which are unlikely in the well-protected wilderness area where it occurs.
Population

This species is locally common in suitable habitat, with subpopulations consisting of more than 1000 mature individuals (N.A. Helme pers. obs.). As it has no severe threats, the population is not suspected to be declining.
