Carbon fluxes at an upland blanket bog in the north Pennines
The peat soils found in blanket bogs are significant stores of carbon. The degree to which these ecosystems are currently functioning as sinks or sources of carbon is not clear. There is a paucity of measurements from suitable sites but the available evidence suggests that certain sites might be …

Linking groundwater level fluctuations and water quality to vegetation and habitat condition in blanket bog ecosystems in Ireland
… past, research has been more focused on raised bogs and blanket bogs have been somewhat neglected. This research aims to help bridge some gaps in knowledge related to blanket bog ecohydrology and its influence on ecosystem services to water, through flow and water quality. <br/><br/><br/>This …

Assessing the condition of the Flow Country peatlands to support their future protection: Monitoring blanket bog functioning during drought and mapping post-wildfire recovery
… for peatland functioning globally, including for blanket bogs, a globally rare peatland types particularly abundant in Scotland, where they hold up nearly a quarter of the UK’s soil carbon.<br/>This thesis combines the use of ground-based empirical data and UAV-derived cover type estimates to …

The impact of conifer plantation forestry on the ecology of peatland lakes
Blanket bog lakes are a characteristic feature of blanket bog habitats and harbour many rare and threatened invertebrate species. Despite their potential conservation value, however, very little is known about their physico-chemical or biological characteristics in western Europe, and their …

Investigating Peatland Margins and Determining the Role of Peatland Margin Characteristics in the Resilience of Blanket Peatland
… a globally rare peatland type called blanket bog. Despite this, many<br/>challenges face the future of this type of peatland, including the increased demand for renewable energy infrastructure, as well as decisions regarding current forestry on blanket bog. Understanding the resilience …

Bog in a Box: Is Long Term Peat Storage for Future Restoration Viable?
… islands, an archipelago densely covered in blanket bog which form the most northerly reach of the UK. In an attempt to mitigate for the damage, it was decided that all 672,000 m3 of peat had to excavated would be stored in purpose built wet storage for use in future reinstatement, a novel …

Peatland Afforestation: Effects and Restoration
… most extensive and ecologically significant blanket bog systems, recently designated as a UNESCO World Heritage Site. This thesis examines the impacts of large-scale non-native conifer afforestation on the biodiversity of this globally important peatland, the ecological outcomes of …

An ecosystem-based management approach for maintaining sandhill crane nesting habitat on northern Vancouver Island
… habitat and biological diversity within the bog wetland complex of the Nahwitti Plateau at the northern tip of the island. Shelter, forage and nesting habitat suitability were identified and rated with a six-class scheme from April to October over a two-year period. Vegetation surveys and …

Developing a trait-based approach to understand <i>Sphagna</i> responses to hydrological stress in the Flow Country
Blanket bogs are a globally rare type of peatland found in high latitudes and cool, wet, oceanic limates. Blanket bog resilience depends strongly on the traits and plasticity of Sphagnum mosses, which dominate blanket bog vegetation communities. However, the scales at which Sphagna traits vary, and …

Carbon Accumulation Rates Over the Holocene in Flow Country Peatlands and the Direct Comparison of Open and Afforested Peatland Carbon Stocks Using Tephrochronology
… With >30% peatland cover, Scotland has more blanket bog than any other country in Western Europe and are estimated to contain carbon equivalent to almost one hundred years of anthropogenic emissions. When damaged and disturbed, these same peatlands can nevertheless turn into a significant …

Studies in the holocene vegetation history of Wensleydale
… pollen diagrams have been prepared for three blanket bog sites and one valley bog in the Wensleydale area of the Yorkshire Dales. Local pollen assemblage zones have been defined for each site using numerical methods, and these have been correlated to give regional pollen assemblage zones. A …

From landscape to freshwater invertebrates: understanding the effects of peatland restoration on Atlantic Salmon (Salmo salar) habitat in the Flow Country
… techniques, drain blocking and forest-to-bog, within the Flow Country blanket bog. We focused on how these restoration activities impact both stream and river water quality, and the potential consequences these changes could have for aquatic ecosystems, especially freshwater …

Weathering below Irish blanket bogs and impacts on carbon dynamics
… demonstrates that traditional models of blanket bog hydrology neglect the influence of substrate flow originating in underlying soil and rock. Stream baseflow from substrate sources is a significant input to catchment streams during periods of limited precipitation. The chemistry of base …

An Isotopic Analysis of Carbon Dynamics in Sphagnum Peat
… associated methanotrophs can be applicable in blanket bog habitats. In the context of methane emissions from peatlands globally, this study indicates that previous estimates of methane uptake by Sphagnum applied broadly in these landscapes would likely overestimates the true extent of this …

Evaluating blanket mire vegetation recovery following hydrological restoration, with specific focus on the influence of Molinia caerulea
… the ecological processes involved in passive blanket peatland vegetation restoration following hydrological rewetting and evaluates the role of Molinia caerulea tussock development as a barrier to blanket mire vegetation establishment. Using data collected from restoration pools and …

The vegetational and archaeological history of the Ingleborough Massif, North Yorkshire
… areas of the massif were covered by spreading blanket bog in this period. All peat profiles have been truncated, three end with the Late Bronze Age; the others continue until the Iron Age on end of the Romano-British Period, at which time the massif was almost cleared of woodland. Regrowth …

Aqueous carbon losses from the Glenfeshie Mòine Mhór
… Mòine Mhór (900-950 m) is an upland blanket bog located in the north-west of the Cairngorms National Park, Scotland. It is currently in poor condition with 242 ha of bare peat located within the 1600 ha study site, equating to 15 % bare peat coverage. This study aimed to further the …
