at 164 sites (8% of original area), of blanket bog at 233 sites (18% of original area) and hectares of fen at 221 sites (58% of original area). These 200,000 hectares of actively growing raised and blanket bogs and fens are of European conservation importance.

Formation

In Ireland two factors led to the formation of such extensive peatlands. High rainfall- there are 175 rain-days each year in the west, southwest and northwest of Ireland and poor drainage The bogs formed at the end of the last ice age, about 10,000 years ago in the central lowlands of Ireland in basins of calcareous boulder clay. These became lakes overgrown with fen vegetation and infilled with fen peat which cut off the surface plants from mineral-rich water below. Nutrient-demanding fen plants were then replaced by bog mosses and plants which could survive on low levels of nutrients. The fen peat below prevented the rainwater draining away and the sponge-like bog moss and plants soaked it up.

Bog flora

The vascular plants characteristic of raised bogs (an example is the Bog of Allen) include:
