Abstract

The purpose of this study was to assess urban lichen diversity in relation to anthropogenic sources of outdoor air pollution, in Nakuru town, Kenya. An ecological survey was conducted in six sampled sites of the town and data of lichen diversity and anthropogenic sources of outdoor air pollution, analyzed. Multi-stage sampling technique was used. A total of 51 lichen species were identified while 6 anthropogenic sources of outdoor air pollution were observed. Results from Fisher’s exact test analysis showed, significant association between the 6 observed anthropogenic sources of outdoor air pollution and lichen diversity. It was concluded that, different anthropogenic sources of outdoor air pollution affect presence and absence of urban lichen species. Hence, more studies on lichens and outdoor air pollution should be conducted in Kenya, to conclusively determine whether lichens should be adopted as an alternative biological method to technological devices, for assessing air pollution.
