Abstract
A strong catastrophic tropical super-cyclonic storm Amphan caused massive damages in the Gangetic delta on 20th May 2020 causing uprooting of thousands of full grown trees alongwith other devastating events. Peltophorum pterocarpum and Delonix regia were found to be excessively uprooted from the cyclonic damage in few selected avenues of northern part of Kolkata city. Paired t-test showed significant differences (p<0.05) happened due to Amphan cyclone in the study sites. Multivariate analysis showed a significant difference in number of roadside trees, footpath area, canopy covered area and girth at breast height (GBH) (p<0.05). canopy coverage area was significantly positively correlated (p<0.01) with width of footpath. Carbon assimilation as tree biomass was greatly reduced in all five selected roads after cyclone Amphan. The present investigation will pave new strategies for sake of plantation programme of trees along the footpaths in and around the tropical urban cities.
