Famous for its role in history, Carew Castle is less well known - but just as important - for its wildlife. The castle, grassland, millpond and mill lane were designated a Site of Special Scientific Interest (SSSI) in recognition of this fact in 1995.

BATS: More than half of all the species of bats found in Britain - including the greater Horseshoe Bat- have been recorded here over the past few years.

PLANT LIFE: Reputedly one of the best sites in Britain for the southern polypody fern. In the grassland around the castle grow spotted medick, knotted hedge-parsley and fiddle dock. There is a variety of moths, beetle and other invertebrates which are important sources of food for bats.

BIRDS: Blue-tits, wrens, blackbirds and jackdaws all make their home in Carew castle. Little owl, tawny owl and barn owl have also been recorded at the castle. The millpond attracts redshank, curlew, common sandpiper and shelduck. Perhaps best known, though, are Carew's resident swans.

SHEEP: Carew has been home to a flock of Jacob sheep since 1988.
