Other Site Characteristics

Garriskil Bog SAC (347.71 ha) consists of two raised bog sites. The main area is Garriskil Bog, which covers 324.81 ha and lies 3 km east of Rathowen in Co. Westmeath A small outlier, Derrya Bog, covers 22.90 ha and lies 2.2 km to the east of Garriskil on the northern shore of Lough Derravaragh. Both bogs are remnants of the large river floodplain bogs which developed where the River Inny enters and leaves Lough Derravarragh. Garriskil Bog is considered to be an excellent example of a Midland raised bog and it includes 170.26 ha of uncut raised bog and 154.55 ha of surrounding hinterland which includes 109 ha of cutover bog. Derrya Bog, which is part of Lough Derravaragh Bog NHA (000684), has been restored as part of an EU LIFE project. The site consists of 2.5 ha of high bog and 20.4ha of cutover most of which was afforested in the 1970s. All the conifer plantations were recently clear-felled and restored by drain-blocking. The bedrock geology of both sites is carboniferous limestone. Garriskil Bog is a large raised bog with 51.7% of the original bog still present. It contains a large, wet high quality central core of Active Raised Bog (ARB) amounting to 50.87ha. There are extensive, well developed systems of pools and hummocks present. Outside the Active Raised Bog area pool complexes are rare and where they do occur they tend to be dominated by shallow open water or algal mats. In a number of places the high bog is being invaded by Downy Birch (Betula pubescens) and pines. The large areas of old cutover bog provides an additional habitat where Purple Moor-grass and Heather dominate, along with cottongrasses, while in some parts Downy Birch woodland is developing. Along the north-east margin of the high bog a narrow band of fen-grassland occurs. Past drainage of the bog, associated with arterial drainage of the Inny and Riffey rivers and peat cutting, has unfavourably impacted on the site and lead to widespread subsidence and drying out. The northern area of the site was also affected in the 1990s by intensive surface drainage which directly affected the area of Active Raised Bog reducing it from 71.23 to 45.12 ha. Those drains were blocked by NPWS in the late 1990s and by 2014 the area of Active Raised Bog had increased by 5.75 ha to 50.87 ha. There has been no turf cutting since the 1990s and though burning has caused damage in the past, there has been no severe fire in recent years. Grazing cattle have caused some local poaching damage to the bog surface. The Derrya outlier is within Lough Derravaragh Bog NHA (000684). Lough Derravaragh Bog is a remnant of a larger area of bog much of which has now been cutover and reclaimed for forestry and agriculture with only 48 ha (approximately 40%) of high bog remaining. A small area of Active Raised Bog habitat (4.61 ha) is present and, based on hydrological modelling, an area of 2.1 ha is considered to be Degraded Raised Bog. In Derrya Bog both the high bog and cutover were planted with a closed canopy plantation of Sitka Spruce (Picea sitchensis) in the 1980s. This conifer plantation was clear-felled in 2011 and the drains were blocked with peat dams in 2013 as part of an EU LIFE project. As a consequence water-levels have risen and some raised bog vegetation has returned to the wetter areas of the high bog. These areas contain Ling Heather, Hare’s tail Cotton-grass (Eriophorum vaginatum), Bilberry, Purple Moor-grass and Tormentil (Potentilla erecta) with the Bog mosses Sphagnum palustre and, in the wet drains, Sphagnum recurvum. There is some scattered Birch and Sitka Spruce regenerating and these are being controlled. On the cutover, now that the conifers have been clear-felled, it is expected that most of this area will develop into dry native broadleaf woodland, but 4.5 ha may be wet enough to support Wet Birch woodland and 1.44 ha of Alder (Alnus glutinosa) - Willow (Salix spp.) woodland along the western cutover. A site specific restoration plan has been developed for Garriskil Bog SAC to help meet the national conservation objectives for raised bogs. One of the key objectives of that plan is to restore the area of Active Raised Bog to 84.9 ha. The area of Active Raised Bog was reported as 50.9 ha during the latest monitoring survey (Fernandez et al, 2014a) and it has been concluded that there is 31.6 ha of Degraded Raised Bog on the high bog which can be restored to Active Raised Bog with the appropriate restoration measures. There is also long-term potential for 2.4 ha of bog peat-forming habitats (BPFH) to develop if restoration measures are undertaken on cutover areas. Detailed conservation objectives have yet to be developed for the Derrya Bog subsite of the SAC but will be produced as part of the restoration plan for the Lough Derravaragh Bog NHA site. Derrya Bog is being actively managed for conservation by the landowner, Coillte, as part of an EU LIFE Project and most of the required restoration measures have already been carried out. An After LIFE management plan is being developed by Coillte for the future conservation management of that part of the SAC. Garriskil Bog is part of the current NPWS Restoring Active Raised Bog in Irelands SAC Network 2016-2020 (LIFE NAT/IE/000032).

4.2 Quality and importance

Garriskil Bog SAC is a site of considerable conservation significance comprising two subsites, Garriskil Bog and Derrya Bog which contain raised bog, a rare habitat in the EU and one that is becoming increasingly scarce and under threat in Ireland. It contains good examples, covering significant areas, of the EU Habitats Directive Annex I habitats Active Raised Bog (7110), Degraded Raised Bog (7120), which is being restored to the priority Annex 1 habitat Active raised bog (7110), and Depressions on peat substrates of the Rhynchosporion (7150). The site already supports a large area of high quality raised bog microhabitats, which is unusual for a site in the east Midlands, including some very well developed hummock/hollow complexes and has a large area with the potential for restoration to Active Raised Bog. Although the Derrya Bog subsite of the SAC is small (22.3 ha) and lacks annex habitats it has been restored and has the potential to support the retention of Active Raised Bog and the restoration of Degraded Raised Bog to Active Raised Bog in Lough Derravaragh Bog NHA (000684). Ireland has a high proportion of the total EU resource of Atlantic raised bog (over 50%) and so has a special responsibility for its conservation at an international level.

6.3 Conservation measures (optional)

Restoration work has been carried out at both bogs but significant amounts of drain blocking is required on the cutover at Garriskil. Tree-felling and most of the drain-blocking have been completed at Derrya Bog except for the boundary drains. The blocking of cutover and boundary drains will require ongoing consultation with other stakeholders. The control of regenerating conifers and birch at Derrya, and dam maintenance and vegetation monitoring at both sites is ongoing. When the restoration management plan is completed for Lough Derravaragh Bog NHA (000684), it will include the management requirements of the section of the SAC at Derrya. The restoration plan for Garriskil has been finalised and it is being currently being implemented as part of the NPWS Active Raised Bog Restoration Project 2016-2020 (LIFE NAT/IE/000032).
