Abstract: 

Soundscape describes all sounds, those of biophony, geophony, and anthrophony, emanating from a given landscape which creates unique acoustical patterns across a variety of spatial and temporal scales. Development of rapid, cheap and efficient biodiversity measurements methods is considered very essential for biodiversity conservation. This study aims at comparing Soundscape and point count methods of biodiversity measurements. Both methods were implemented at Akrotiri and Ayia Napa, Cyprus for two days in each site for a period of 3 hours per day between 6:00-9:15. A total of 45 species were recorded from the entire survey in combination of point count and Soundscapeaural identification. Species recorded only from point count and not identified by any other survey method were 21 species and 5 species were identified by only Soundscape method. Species identified equally by both point count and Soundscape methods were 19 species. Acoustic Richness (AR) revealed significantly higher species richness in Akrotiri than Ayia Napa. However, both sites where not significantly dissimilar based on the Acoustic Dissimilarity index. This study provides evidence of high difference between Soundscape and point count methods of biodiversity measurement. Thus, a complementary technique involving both methods is highly recommended for more accurate biodiversity measurements relative to the employment of the methods individually.
