“…More recently, Crushell (2008) surveyed the aquatic macroinvertebrates of Clara bog, Co. Offaly, a raised bog which is particularly important for its soak systems. Other studies have described the macroinvertebrate fauna of artificial lakes found on cutaway raised bog in County Offaly (O'Connor et al, 2000). de Leeuw (1986) investigated the occurrence and distribution of macroinvertebrates in peatlands along an east to west gradient across the country in summer 1984 but this remains unpublished and relatively inaccessible.…”

The purpose of this study was to consider the relative importance of several habitat variables in explaining the patterns in the structure of macroinvertebrate assemblages in open-water habitats, in relatively intact bogs and fens, which should inform conservation strategies. It was hypothesised that variables relating to the size of the water body would differentiate the communities and that some species would be unique to certain conditions. The macroinvertebrate communities from pools [100 m 2 , 10.1-100 m 2 and Sphagnum hollows were characterised using sweep sampling for eight intact peatland sites across four bog types, and related to habitat variables including pool size, Sphagnum cover and hydrochemistry. Results showed community composition and structure differed significantly between deep, permanent pools and shallow, droughtsensitive Sphagnum hollows, with larger invertebrates, such as Odonates and Dytiscinae, rarely found in the hollows. Sphagnum cover accounted for a substantial amount of the variation in community composition. An examination of life-history strategies found species dependent on predictable conditions for juvenile development to be more abundant in pools. In contrast, taxa that could delay juvenile development until conditions were favourable were more abundant in Sphagnum hollows. These results highlight the importance of habitat heterogeneity in maintaining macroinvertebrate diversity in peatlands.

“…Peatland habitats have also been incorporated in numerous studies that describe the distribution of different invertebrate groups in Ireland and Northern Ireland (Foster et al 1992;Nelson et al 1998;Nelson 2005). Only a small number of studies have described the communities of restored sites (O'Connor et al 2000;Trodd 2003;Higgins et al 2007). In the present study aquatic invertebrates were chosen as the ecological indicator in order to assess the success of the restoration measures employed at Kippure/Liffey Head blanket bog in County Wicklow.…”

Peatlands in Ireland have been subject to peat extraction and drainage for many years, with detrimental effects on the fl ora and fauna of the ecosystem. Blanket bog has been listed for protection under Annex 1 of the EU habitats directive, making the conservation of intact bogs as well as the restoration of degraded sites a priority. In order to assess how effective a restoration measure this has been it is important to look at the biodiversity within the site. This study compared the macroinvertebrate and microcrustacean communities in open-water habitats of an intact and a restored mountain blanket bog in County Wicklow over a number of seasons. It also examined the hydrochemistry of both treatments. Hydrochemically there was no difference between the restored and intact pools. Neither was there any signifi cant difference between the two in terms of taxon richness, abundance, community composition or structure. Season was found to significantly affect the structure of the invertebrate communities in both areas. It is not known how long it takes a peatland to return to its natural state. However, we can conclude that the restoration measures implemented fi fteen years ago have provided an aquatic habitat similar to that of the intact site.

“…Despite over 50 years of research into commercial, market-driven after-use options for cutaway peatlands, the non-market options have rarely been explored to any practical extent. In those peatland areas that have been fully harvested, spontaneous and/or managed regeneration has been shown to promote new nature which infers that cutaway areas have the potential to be used to augment biological diversity (Foss & O'Connell, 1996;O'Connor et al, 2000;Rowlands & Feehan, 2000;Trodd, 2003). There is some evidence that local communities may place a high value on non-market after-uses of regenerating peatlands (Barron et al, 1994;Egan, 1994Egan, , 1999Foss & O'Connell, 1996;Anon., 2006), but a working blueprint to realise this has not yet been established nor has there been an audit of community perceptions of peatlands either intact or harvested.…”

Industrially Harvested Peatlands and After-use Potential: Understanding Local Stakeholder Narratives and Landscape Preferences

Recent years have witnessed much debate on the turn towards community within landscape management and planning. This is particularly evident in the European Landscape Convention which asserts the legitimacy of local preferences and citizen involvement in policy processes. This paper explores a bottom-up perspective on people-place relationships in a changing landscape, through assessing the after-use potential of industrially mined peatlands in Ireland and the rehabilitation of degraded landscapes. The mining of the peatland resource has a longstanding tradition in Ireland, however, significant attention has now focused on exploring market and non-market uses of remains after harvesting has finished resulting in a cutaway landscape. We argue that local people's everyday experiences of the landscape is a legitimate form of knowledge and should provide a key input into deliberative planning and management processes. Drawing largely on an interpretive research approach, we assess key local narratives in relation to harvested peatland landscapes and explore local people's after-use preferences. There appears to be strong support among the local community for amenity/biodiversity after-uses, which are currently not reflected in public policy debates. We review people-place relationships and discuss the role of ethnographic research in a peatland context as well as defining the relevant stakeholders. Finally, conclusions are developed to identify wider lessons for people/place relationships within the context of landscape management and planning.
