The entire site is almost 8 kilometres in length and 2.5 kilometres in width, comprising an ‘intermediate’ peatland site with characteristics of both raised and blanket bogs. At several locations the peat is up to 8m deep, unusually deep for this part of the country. The bog is surrounded by the Muirkirk Uplands, which are made up of heather moorland, upland grassland and blanket bog. It is now the largest area of unafforested moorland in South Strathclyde, but is bordered by large forestry blocks in several areas. Airds Moss and the Muirkirk Uplands are of national importance for hen harrier. The whole area qualifies as a Special Protection Area under the terms of the European Union Birds Directive. The 26,330 ha SPA is of national importance for breeding curlew and short-eared owl and further supports merlin, peregrine and golden plover. Airds Moss and the Muirkirk Uplands are also of significant interest for other breeding birds including black grouse and waders such as snipe, redshank, lapwing and dunlin. The RSPB manage large areas of Airds Moss, and originally became involved with the site due to a series of threats that could seriously damage the habitats and wildlife of the area. The Society’s operations at Airds Moss are primarily to ensure site protection and to work in partnership with developers to ensure no net loss of habitats. This report summarises the results of monitoring at the CEI’s peatland enhancement sites at Airds Moss between 2014 and 2018. 2 Background There have been six separate phases of peatland enhancement work at Airds Moss, within the RSPB Reserve. The first three phases were delivered by RSPB and the fourth phase of work was by EACEI before the EcoCoLife project commenced. Initial phases 1-4 (not funded by EcoCoLife) Phases 1-3: were carried out by RSPB between 2009 and 2012 (Fig. 1). Peat and plastic dams were installed in the drainage network. Phase 4: Carried out by CEI in 2013-14 (see Figs. 2 & 3). The enhancement area was 131ha and the value of the contract was £30,000. The work was carried out by Openspace (Cumbria) Ltd. 2,097 peat dams, 16 plastic piling dams were installed. 2 Figure 1: Airds Moss peatland enhancement, Phases 1-3 by RSPB (c) RSPB Figure 2: Airds Moss peatland enhancement, Phase 4 by EACEI (c) RSPB 3 Figure 3: Airds Moss peatland enhancement, Phase 4 dam locations (c) CEI Figure 4: Map showing Airds Moss peatland enhancement phases including phase 5 (2014- 15) (c) EACEI 4 Phases 5 and 6 were undertaken and funded through EcoCoLife. Phase 5 was completed in early 2015, enhancing the site across 111 ha (Fig. 4). Phase 6 involved repairing historic dams and installing new dams to reinforce areas subject to damage. An additional area also had ditch blocking carried out (Fig. 5). Table 1 summarises the actions undertaken in phases 5 and 6.

Baseline monitoring – carried out prior to enhancement activities. 2. Initial monitoring period – following completion of works, carried out within the EcoCoLife project timescale to identify any short-term changes. 3. Long-term monitoring – ongoing monitoring to be carried out at 3, 5, 10 year intervals to measure long-term changes. Table 2 describes the monitoring methodology. 6 Monitoring Vegetation Fixed point Water level monitoring Peat depth Species surveys tool monitoring photography Species of Ecological Indicator of Ecological functionality Structure Structure conservation functionality importance Each site exhibits the full Stable or increasing relevant species range of structural populations of positive A long-term surveys carried out to features which should be bog indicator species, monitoring system in assess how particular expected for a functioning High, stable water table, close to particularly relevant place which will allow species not captured Target bog.
