Two small, isolated subpopulations remain on small remnants of lowland fynbos between Atlantis and the Paardeberg near Malmesbury (EOO 8 km²). The largest subpopulation consists of about 50 mature individuals, the second subpopulation has only 10 plants. It continues to decline due to ongoing habitat degradation, as well as competition from alien invasive plants.

Lowland renosterveld on transition zones between clay and acid sands.
This species has lost over 95% of its habitat to crop cultivation, urban expansion and dense infestations of invasive alien plants. Remaining plants are threatened by competition from alien invasive plants as well as livestock grazing.

Marasmodes fasciculata is known historically from only two locations. At the type locality south of Mamre, it was last recorded in 1971. Fynbos in this area is now severely degraded due to agriculture, urban expansion and dense infestations of alien invasive plants, that it is uncertain whether this subpopulation survives. It was first recorded on flats at the eastern base of the Paardeberg in 1937, and again, at the same locality in 1980. Recent field surveys relocated this subpopulation, which consists of fewer than 50 mature individuals. A third subpopulation was discovered in 2012 on a small fragment of sand plain fynbos near Mamre. This privately owned site is in the process of being secured for conservation through Biodiversity Stewardship. Only about 10 mature individuals occur at this locality.
