Abstract

The objective of this study was to evaluate the floral biodiversity and sustainability of Lagos wetlands. In other to achieve this, mangrove communities of 8 localities in Lagos and its environs viz: Atlas Cove, Five Cowrie Creek, Maroko, Berger De Motz, Palaver Island, Bayeku, Majidun and University of Lagos beach were sampled. A comprehensive quantitative vegetation analysis of the vegetation within the selected lagoonal communities was carried out. Of the 8 sampled sites, only 2 - Palaver Island and Bayeku had their vegetation relatively well preserved. Mangrove at the vicinity of University of Lagos and Majidun preserve relics of their biodiversity. There was evidence of anthropogenic stress at Five Cowrie Creek, which is devoid of vegetation. Maroko swamp has been taken over by grasses, Berger De Motz has sandy substratum, high-energy wave and rip of any typical mangrove species. The study reveals that mangrove swamps in Nigeria are under serious anthropogenic threat. To ensure that these wetlands are not soon forgotten, pragmatic measures which must be put in place to curb degradation, restore, sustain and preserve this vital ecosystem are suggested.

Key words: Degradation, natural environment, restoration, standards, wetlands.
