This work focuses on aspects of diversity in the Pogoni area of Epirus, Greece and more specifically on its sheep farm system. Diversity is initially examined at the area level and then successively considered at the household and sheep farm levels. Two methods are basically employed: (i) secondary data analysis; and (ii) the case study results of three selected communities in the Pogoni area, where an ethnographic type of approach was primarily used. Area level diversity has been mainly predicated on biophysical, socio-economic and demographic factors which have been culminated in shaping two zones in the area, where a number of household structures around the nuclear and extended types are identified. Diversity among the sheep farms observed within the frame of ethnographic approach seems to be higher in the plain community of Doliana but generally can be subsumed under two main versions of sheep farming in the area along the continuum of intensification-extensification.
