In 2004, a population of the Tadpole Shrimp Triops cancriformis (Bosc.) (Crustacea, Branchiopoda, Notostraca) was discovered in a small, temporary (ephemeral) pool at the Wildfowl & Wetlands Trust (WWT) reserve at Caerlaverock, on the Solway Firth, in Dumfries & Galloway, on land jointly managed with Scottish Natural Heritage (SNH) on the Caerlaverock National Nature Reserve.
