Justification
Gazania caespitosa has a restricted distribution range, with an extent of occurrence (EOO) of 1182 km², and is known from only eight subpopulations. It however has no severe threats and is therefore not in danger of extinction.

Description
It occurs on high altitude grassy hills and summit plateaus. This species grows as dense and compact cushions.
Threats
Field surveys indicate that this species has no severe threats.
Population

For a long time, this species was only known from the type specimen, collected in 1872 at an unspecified locality in the 'Koudeveld' Mountains (Sneeuberg) west of Graaff-Reinet (Roessler 1959). It was rediscovered in 2006 during an extensive surveys of the high altitude grasslands of the Sneeuberg Complex (Clark et al. 2012), and at least eight formerly undocumented subpopulations were recorded. This species occurs in isolated subpopulations, but can be locally common, forming large stands of more than 50 plants. As no severe threats were observed, the population is not suspected to be declining.
