Impatiens johnii has high conservation concern due to its rarity and geographical narrow range. This species is a stenotopic endemic in the Munnar landscape and rediscovered after 67 years. This plant was found as part of epilithic along the streams and high canopy areas in high humidity locations at an elevation of 1600–1800 m amsl. I. johnii is distributed in less than 5 km2 area near Eravikulam National Park and therefore this area needs to be protected for the conservation of I. johnii.
