Breeding bird populations of Irish peatlands : capsule peatlands are very important habitats for birds despite low species diversity

Aims to describe the variation in breeding bird populations that occur on different types of Irish peatlands and their associated habitat characteristics. Methods: Bird abundance and diversity were compared between four peatland habitat types: fens; raised bogs; Atlantic blanket bogs; and montane blanket bogs at twelve study sites using transects. Various measures of habitat quality were also taken at each location. Results: Only 21 species were recorded during the study with Meadow Pipit Anthus pratensis and Sky Lark Alauda arvensis accounting for over 80% of all birds recorded. Fens had greater bird species diversity and densities than the other three peatland types. Raised bogs, Atlantic blanket bogs and montane blanket bogs were very similar in terms of their avian diversity. Each of the recorded bird species were associated with different aspects of the peatland habitat. Conclusion: This study shows that despite the relatively low avian species diversity of Irish peatlands, they are of enormous conservation value due to the presence of species of high conservation concern such as Red Grouse (Willow Ptarmigan) Lagopus lagopus and Eurasian Curlew Numenius arquata.Other funderEnvironmental Protection Agency (EPA)ke, ab, sp, li - TS 26.04.1
