Ireland’s biodiversity stems in large part from the exceptional diversity of its geology – the bedrock that underlies the landscape. This has shaped our landscape with its mountains, rivers and very varied coastline. As a result of this variety, we have an exceptional diversity of habitats, given the size of the island. The second factor influencing our diversity is our mild, moist climate which allows unusual combinations of plants and animals to survive. For example, in the Burren, County Clare, arctic-alpine plants are found side-by-side with species that are otherwise more common in Mediterranean countries.
