Pollagoona bog is an area of high quality blanket bog located in the extensively afforested Slieve Aughty uplands of County Clare, some 20km southeast of the town of Gort (Co. Galway). Lough Atorick lies just to the northwest of the site. The bog is completely surrounded by conifer plantation, dominated by Sitka spruce, most of which is more than 15 years old. The bog is of particular interest as it displays vegetation and morphological features transitional between blanket and raised bog systems.

In general, the bog is of high ecological value, being soft, wet and quaking over most of its surface. Sphagnum cover is high, with some well developed hummocks while wet lawn areas, dominated by white-beaked sedge (Rhynchospora alba), are also frequent. In the more central parts of the bog, plant species such as bog asphodel (Narthecium ossifragum) and cross-leaved heath (Erica tetralix) dominate, along with Cladonia portentosa and Sphagnum capillifolium. A feature of the bog vegetation is the presence of bog rosemary (Andromeda polifolia) and cranberry (Vaccinium oxycoccos), species that are more typical of raised bog habitats. Along the intact bog margins, where the peat depth is shallower, i.e. <1 metre, the vegetation is dominated by purple moor-grass (Molinia caerulea). Pool areas are generally not common however there is a small pool complex in the eastern half of the site which is colonised by bog-bean (Menyanthes trifoliata), mud sedge (Carex limosa), brown-beaked sedge (Rhynchospora fusca) and the aquatic mosses Sphagnum cuspidatum and S. auriculatum. As a result of the high ecological quality of the area it has been designated as a Special Area of Conservation.

The main restoration measure at this site involves the felling of poorly-developed areas of conifer plantation around the margins of the intact unplanted bog and the subsequent blocking of drains. This will increase the area of bog habitat over time and will also prevent the drying out of adjoining intact areas. In these afforested areas a modified bog vegetation is often still present and there will be good regeneration of blanket bog following tree felling.
