Cwm Idwal National Nature Reserve holds a variety of habitats which sustain a host of insects, small mammals, amphibians, reptiles, fish and birds. The habitats include wet, and dry heath, acidic grassland, calcareous grassland, tall-herb cliff ledges, nutrient poor lakes, and montane heaths. Here are some of the species that can be found at Cwm Idwal.<\/p>\n\n\n\n

Mammals<\/h2><\/div>\n\n\n\n
<\/div>\n\n\n\n

It is fairly infrequent that you’d spot mammals in the nature reserve, often they are well hidden or only venture out between dusk and dawn. Among these mammals are stoats, weasels, moles, bats, goats and foxes.<\/p>\n\n\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t
