Marsh Frog Pool Frog Edible Frog Alpine Newt Italian Great Crested Newt Midwife Toad African Clawed Frog I've also removed from the wild: Green Toad Firebellied Toad (Bombina bombina) I have no idea if these were breeding or not.

I think Julia Wycherley's acoustic studies have identified some of the more obscure green frogs in the UK, I can't remember the exact species off-hand, possibly R. bergeri and R. perezi? Gemma- are you sure your firebellies were B. bombina? B. bombina are quite rare in captivity these days, and brown B. orientalis are often identified as B. bombina.

There has however been an eradication programme in recent years, at least at one breeding site. GemmaJF38752.4824884259 Gemma Fairchild, Independent Ecological Consultant
