Common Frog - Rana Temporaria
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.
Great Crested Newt - Triturus cristatus
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.
