Our friends from the Bedfordshire Reptile and Amphibian Group visited and surveyed the pond again this month, and have reported a good population of great crested newts.
They had no difficulty finding eggs, even this late in the season, and also found great crested and smooth newt larvae. They did not see any frog or toad tadpoles.
They conducted a Habitat Suitability Index calculation of the pond for great crested newts which came out at 0.83, which is ‘excellent’, although this has to be treated with a degree of caution because of the uncertainty about the suitability or otherwise for great crested newts of other ponds within 1 km of our pond. The key point is connectivity – a totally isolated pond community is vulnerable and it helps sustain genetic diversity if there is interchange between one pond community and another.
