The action of glaciers 10,000 years ago has left many areas of exposed rock within the National Park. While at first they may seem inhospitable to wildlife, a closer look will find that some wildlife can survive here.
Mosses and lichen can grow on bare rock and are helped by the high rainfall and moisture available in the uplands. Where the rocks are cracked, thin soils can develop from dust blown in or left behind by rain. Tiny amounts of soil can be enough for plants to grow, while the cracks and holes themselves can be homes for insects.
The rich geological heritage of the National Park has led to the designation of the Fforest Fawr Geopark.
