A study was carried out at a rehabilitated locality in Haryana, north India, where waterlogging was a usual phenomenon that extended for more than nine months annually. Arbuscular mycorrhizal (AM) distribution in all the plots represented by various tree species, viz. Terminalia arjuna, Syzygium cuminii, Populus euphratica and naturally grown Typha elephantina was found to be significantly different. Distribution profile showed the dominance of the two genera, viz. Glomus and Gigaspora. Glomus was dominant in the T. arjuna plot while Gigaspora was abundant in the P. euphratica plot. Glomus showed positive correlation to available soil P (r = 0.74, p = 0.05) while Gigaspora showed positive correlation to organic matter content (r = 0.94, p = 0.05). Both the genera also predominated at the naturally grown T. elephantina plot.
