There are more than 15 known locations and all of them have different ongoing threats. The occurrence biome is the Humid Tropical Forest from 13 to 957 m elev. The state of conservation of the habitat of this species can vary from region to region, but it is mainly affected by activities such as agriculture and the growth of small cities. As there are no information on population severely fragmented or population size to access this taxon under different criteria, Eugenia riograndis is classified as Least Concern (LC). Specimens examined:— MEXICO. Chiapas: Breedlove 23349 (MEXU!); Tabasco: Matuda 3241 (MEXU!). Belize: Gentle 4711 (LL); Guatemala: Molina R. 15541 (F).
