Background: The aim of the study was to document the prevailing indigenous knowledge and various uses of lichens among the lichenophilic communities in the hills and mountainous settlements of Nepal. Methods: Ethnic uses were recorded during twelve field trips, each of roughly 15 days in three consecutive years, through direct questionnaires administered to 190 respondents. Lichen samples were identified applying microscopic observation and thin layer chromatography (TLC). Voucher specimens of identified species are deposited at TUCH (Tribhuvan University Central Herbarium) in Nepal. Results: Lichens are being used in several ways by different communities of Nepal. We recorded the ethnic use of seven species of lichens belonging to four families (Parmeliaceae, Physciaceae, Ramalinaceae and Usneaceae) and six genera (Heterodermia, Everniostrurn, Pormotrerna Romalina, Thomnolia and Usnea) among the Limbu, Sherpa, Lama, Gurung, Rai, Dalit, Tamang, Chhetri and Brahman communities. The present study revealed six use values namely; Medicinal value (MY), food value (FV), ritual and spiritual value (RSV), aesthetic and decorative value (ADV), bedding value (BY) and ethno-veterinary value (EVV) from different parts of Nepal. Three lichen species, Everniastrum cirrhatum, E. nepalense and Parmotremo cetrotum were consumed by the Limbu and Rai communities. The Limbu and Sherpa ethnic groups are regarded as most lichenophilic communities while respondents from Brahman, Chhetri and Tamang communities showed less interest in lichen uses. Conclusions: The present study contributes to document traditional knowledge on various uses of lichens among nine communities with three different cultural background, inhabitants of eight different altitudinal levels of Nepal. Regarding the six values as identified from this research, significant difference (p = <0.05) were found along altitudinal gradients or locations of the settlements, cultural groups and ethnicity of the respondents.
