Happy New Year to you all. It’s January and the start of 2025, our weather doesn’t seem to be getting any more predictable and the warmer winters do have an impact on our amphibians and reptiles. These animals usually rest up over winter, either in the bottom of ponds, in rocky crevices or finding places underground to brumate, hidden away from cold or freezing conditions.
As the climate warms, however, we are noticing changes in behaviour. Our winters in the UK are now generally milder and can tempt amphibians and reptiles out of their brumation state. With reports of newts and frogs in ponds in January, even in full breeding condition, is now fairly normal in southern counties. Snakes and lizards will also make an appearance when the winter sun is strong enough, and all this would have been unheard of 15 or 20 years ago.
All the evidence is now pointing to our reptiles and amphibians emerging from their slowing-down period and breeding earlier than ever before, in response to our ever-changing climate.
It is still too early to predict the implications of these changes in behaviour, but a consequence of this has been on our reserve at Hampton with delayed pond maintenance due to the higher risk of harming our pond animals as they stay active for longer. This year we will be starting our great crested newt surveys earlier in response to breeding patterns.
With an unpredictable climate it can cause issues if newts, frogs or toads breed earlier with higher risks of frozen ponds, spawn and eggs. Being more active over winter could also have negative impacts on our species life expectancy- using up energy reserves when they would normally be brumating. Food sources will be scarce over the winter months, so feeding becomes harder.
You can help us in our research by uploading your sightings of frogspawn or any amphibians and reptiles on our free Dragon Finder App – these records help us learn more about how our changing climate affects our species.
first time to reach dry land. They will often leave en masse as there’s safety in numbers!
Summer is arriving! As June has the greatest number of daylight hours during the year and is often one of the warmer months, this can be an enticing time for reptiles.
Potentially as early as January in the South East of England, and up to April in other areas of the UK, the common frog will emerge from their winter hideouts and head back to a pond. Male frogs will ‘piggy back’ on their chosen female using their nuptial pads to hold on tightly. This is a process known as ‘amplexus’. He will then fertilise her spawn as she lays it. Common frog eggs are laid in clumps, with up to 2,000 eggs laid in one single clump. Female frogs can lay up to 4,000 eggs over one breeding season.
Common toads will ritually return to the same pond for breeding each year where possible. They take advantage of warmer, damp spring evenings to leave their overwintering sites and return to their specific pond. This behaviour makes them notorious for crossing roads over night and putting themselves at risk of being run over. Our 
Once the warmer weather of spring hits, newts too will venture back to a suitable pond to breed and lay eggs. Males of each newt species will perform elaborate ‘dances’ to attract the attention of females, who will choose which male gets to fertilise their eggs. Newt eggs are laid in a very different way to toads and frogs. A female newt will lay each egg individually, she will lay the egg on the leaf of an aquatic plant and carefully fold the leaf around the egg to protect it, giving the leaf a very straight edge where it has been folded over. Newts lay less eggs than their toad and frog counterparts, but females will still lay hundreds over the season.
