Habitat and Ecology
Major system
Terrestrial
Major habitats
Fynbos
Description
It is localized to sheltered, shaded places under rocks, or in rock basins in montane fynbos.
Threats
This species occurs in a remote montane area that is well-protected. It has no threats.
Population

Crassula elsieae is known from three isolated subpopulations on the highest peaks in the Cederberg and Skurweberg mountains. It is a highly localized habitat specialist, but also likely to be overlooked and more common than records suggest. Plants are cryptic, and in addition occurs in remote and inaccessible montane areas. As there are no threats, the population is not suspected to be declining.
