Potentiality of wall flora in characterization of urban ecology

Environmental Biology

City walls are considered secondary habitat of urban biota and communities serving as a knowledge center of floral heterogeneity. The old and ruined city walls containing favorable growth factors like temperature, humidity, nutrients, houses unique plant assemblages and thus can be managed for evaluating floral diversity. The wall vegetation mainly depends on physical characteristics of wall material, vertices plant types and composition. Special technology in wall engineering enhancing the quality and favoring species composition should be given special emphasis in urban areas. The natural and living wall not only provide valuable information about the changing land pattern but also makes air clean, maintain carbon footprints and balances the ecology of the township. Assessment of fortification wall and pavements sometimes helps in recovering the rare, endangered or alien species and also help in understanding ecological problems and parameters. Thus the wall flora can also be referred as cultural landscapes and is significant in understanding the ancient objects and ecological features of any urban ecosystem.
