Eriosyce senilis in 6 Inch Container Live Cactus
Origin and Habitat: Eriosyce senilis is endemic to chile (Coquimbo, Valparaíso and Metropolitana regions, from Elqui Valley to the north of Metropolitana). It has a relatively small range (extent of occurrence =16,000 km2),
Altitude: 350-2000 metres above sea level.
Habitat and Ecology: The species is frequent but not abundant among small valleys and traverse to the sea in sclerophyllous forest and thorny scrub on rocky soils, the populations are severely fragmented, and illegal collection is causing a continual decline in the number of mature individuals. Furthermore, land conversion for agriculture and urbanization is degrading the habitat surrounding the species.
