Don't think I can give a definitive list but if I make a start with those species I know to be surviving may be others can add more known to be surviving species?

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.

There might still be American bullfrogs breeding out there... hopefully not, though.

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.

Your right Caleb, typing slip they were brown B. orientalis not B. bombina

Xenopus still persist at some locations, there are also likely to be as yet unknown populations.

There has however been an eradication programme in recent years, at least at one breeding site.
