If you’ve visited our ponds recently you’ll have noticed a very clear sign that Spring may be on its way, frogspawn! Large clumps of spawn have been deposited in our ponds and if you’re lucky you might even be able to spot the adult frogs. We are very happy to see local amphibians using our ponds following our recent work clearing up and planting around the ponds with Froglife.

However, temperatures are still very low overnight and we have certainly not seen the last frost and the ponds occasionally freeze overnight. We even spotted ice on the frogspawn! Many animals must time their behaviour carefully with the start of Spring and we hope the frogs have gotten it right. Let’s hope many of the eggs hatch and many of those tadpoles will survive and grow into adult frogs!

Frogs are loving the newly restored ponds and wetland area! The amorous amphibians have been spotted in the water and their developing eggs can be found along the edges of the pond.

We began restoring our ponds and wetland area in October, working with Froglife to clear to clear weeds and create a new viewing platform (find out more about our clean-up day here) and the current breeding European Common Frogs (Rana temporaria) are a testament to all our hard work!

The eggs will develop rapidly over the next few weeks, with their development dependent on the temperature. Warmer temperatures mean faster development. The black spheres shown in the image above will develop into tiny tadpoles, then break free from their eggs.

These eggs are beginning to develop, with the embryo starting to resemble a tadpole.

Frogs are just one of many species to live and reproduce in our ponds. To find out more about pondlife and our restoration project, join us on Thursday, April 17th from 11 to 3 for the official relaunch of the ponds with Tower Hamlets and Froglife!
