Conservation ''Griffinia intermedia'' is categorized as endangered (EN) by the IUCN Red List of Threatened Species. It is only known from two locations, in which the species, as well as its habitat is continually declining. An initiative has been taken to replicate the fragrance of ''Griffinia gardneriana'', which is threatened with extinction, for the creation of a perfume. The sale of the perfume is meant to financially contribute to the conservation effort for this species.
