During recent field surveys, a new Ceylon iron wood (Manilkara hexandra) population was discovered in the Upper Ganga Ramsar Site, Uttar Pradesh (UP), India. The largest specimen located at Van Khandeshwar partially collapsed in 2012, which led to a canopy impairment. The rupture enabled direct extraction of samples close to the pith of the main stem. The radiocarbon date of the oldest sample was 361 ± 23 BP, which corresponds to a calibrated age of 525 ± 25 cal yr. The results indicate the Ceylon iron wood of Narora, UP is the oldest dated extant M. hexandra with a calculated age of 550 ± 50 yr. Several protection measures are presented and urgent action is required to prevent the total collapse of this ancient tree.Keywords

This article describes the radiocarbon analysis of the large Indian banyan (Ficus benghalensis) at Narora, Uttar Pradesh (UP). It was discovered during floristic surveys in the Upper Ganga Ramsar site in UP and ranks as the tenth largest banyan tree in the world with its 4069 sq. m crown spread. The tree has a unique architecture, with just four prop roots supporting the main stem. The oldest sample was found to be 346 ± 40 years bp, which corresponds to a calibrated age of 430 ± 35 cal years. The radiocarbon dating results indicate an age of 450 ± 50 years for the Indian banyan at Narora. This age represents the oldest accurate dating result for the species. Several protection measures are included to ensure the long-term survival of this archaic tree.Keywords
