The South African Red List classifies Marasmodes dummeri as Endangered (EN). This is because it occurs in two nutrient-rich habitat types that are used for agriculture. Only a small amount of natural vegetation remains scattered in isolated fragments among crop fields. This species is said to be locally extinct in historical localities where it used to occur, but fortunately there is one large subpopulation in a provincially protected area with around 200 plants from the roughly 500 plants left in the wild. This species remains endangered because of the ongoing agricultural expansion and other developments in its remaining habitat. As a conservation intervention, the Millennium Seed Bank Partnership in South Africa, particularly in the Western Cape, has collected the seeds of this threatened species at Paarl in 2022. This collection is new to the bank and will be kept safe in the bank in Kew until the Seed Bank at Kirstenbosch National Botanical Garden is developed and running, then half of this collection will be withdrawn to be banked in our own bank in South Africa. In another great conservation intervention, the Custodian of Rare and Endangered Wildflowers (CREW) designated "Marasmodes Day" on Freedom Day, 27 April, as a day to advocate for the freedom and protection of plants of this genus, and for CREW volunteers to visit all the locations to monitor these endangered species.
