Species such as Grewia and those in the Euphorbiaceae are considered to be fire-sensitive and typically restricted to termite mounds instead of dominating the open savanna However, E. candelabrum is widespread throughout the savanna and short-grass areas of the Queen Elizabeth National Park in Uganda. This is an unusual habitat for tall succulents, as they have been proven to typically be poor invaders of frequently burned stands of land. E. candelabrum's success as a tall succulent seems to be a result of heavy grazing by African mammals such as the Ugandan kob (Kobus kob) and waterbuck (Kobus ellipsiprymnus defassa) and an overall decrease in intense wildfires.
