Coed-y-Werin is an area of semi-natural woodland with ponds. It is a Site of Importance for Nature Conservation and its variety of habitats provide homes for many types of wildlife. There are small mammals including the Yellow Necked Mouse, as well as the endangered Hazel Dormice (we must stress these are illegal to handle without a license); reptiles such as the adder, grass snake, slow worm; bats can be seen in the late evening, and amphibians such as frogs, toads and newts are plentiful.
The area is a birdwatchers paradise with over 60 named species, including buzzards, woodpeckers, herons, crossbills, kingfishers, owls and hawfinches. Look for the tiny Treecreeper that climbs upwards around the tree trunk looking for insects and the flash of colour as the Kingfisher flies across the pond, listen for the raven and Buzzard as they circle overhead making their distinctive calls.
