Due to its high elevation, mount Idoukal'n'Taghes has been found to host a number of Saharan-Mediterranean and Tropical plant species that have never been recorded elsewhere in Niger.
Zahvaljujući visokoj nadmorskoj visini, Mont Idoukal-n-Taghès stanište je brojnim saharsko-mediteranskim i tropskim biljnim vrstama, koje nikada nisu nađene na drugim mjestima u Nigeru.
