For years Frogs have been living in my garden pond. We originally had Toads as well but unfortunately these are no longer there. I have counted as many as 80 frogs in the pond spawning, not bad for an area of about 12ft diameter.
Last year 2019 we found we had Great Crested Newts in the garden pond. I was modifying a loose stone wall and one shot out. The wall has been made an even better retreat now snd the newts are very happy to live there.
Smooth Newt - Lissotriton vulgaris
I had a good look at online references to make sure these are smooth newts. The location and the orange underneath define them so I think.
