Diversity of Epiphytic Lichens in Urban, Peri-Urban and Adjoining Rural Areas of Benin City to Monitor the Ecosystem Health
Lichens are widely used as biomonitors of environmental pollution, few lichen studies have been used to assess environmental quality in Nigeria. Managed and natural areas within Benin City metropolis and adjourning areas were investigated using lichen diversity to determine the ecosystem health status in four sites: Urban, Peri-urban, Rural and the Reference site. Lichen colonies obtained in triplicates per site from 10 mature trees (>60cm ghb) were collected and identified using standard keys and manuals.
