Tired as a newt

My legs ache like I’ve just climbed a mountain, and I’m sleep deprived. It’s all the newts’ fault.

Earlier this week I helped out with a newt survey, which was great. But newts, being nocturnal, have to be surveyed after dark, and then very early the next morning, which meant I missed a few crucial hours of beauty sleep. (You didn’t think I look as gorgeous as I normally do without a good 8 hours slumber each night, did you?) And as newts live in ponds, there’s quite a bit of crouching down needed to extract bottle traps and release newts back into the ponds, hence the achey legs.

But they’re so enchanting and strange, I forgive them my aches and doziness.

I joined staff at Surrey Wildlife Trust to monitor newts in ponds on one of their reserves. Spring is the best time to monitor newts, as at night they can all be found in ponds where they congregate to breed.

We used 3 approaches to survey the newts. The first, lamping, involves shining a bright torch into ponds to see what you can see. This was remarkably effective, and we saw lots of both smooth and great crested newts. It takes a bit of time to get your eye in, particularly to distinguish between males and females of the same species, but I was amazed how many we saw.

Another surveying method is to set traps made from bottles, Blue Peter style. You set them in the evening, and check them very early on the morning to release anything you’ve caught, before it gets too warm or they run out of air. This also worked well, and I got some wonderful close-up views of both sorts of newts.

The other approach is to look for newt eggs folded individually into the leaves of pond plants.

Great Crested Newts are rare and protected by law, like dormice and bats, which means you can’t do anything to disturb them (including these survey methods) without the supervision of a licence holder. This, combined with their nocturnal and discreet way of life, and scarcity,  means it’s rare to get a good look at them.

They are very fine looking. In the water they look like marine iguanas, and their bellies are startling bright orange with bold black spots.  Smooth newts are small, neat looking things.

While it was a bit hard leaving my bed at stupid o’clock, it was definitely worth it – the early morning is my favourite time of day, and it’s lovely in the woods. I did have a secret smugness as I later boarded my train to work, the other commuters having no idea what I’d been up to an hour earlier.

So that’s two out of three types of newts ticked off my British Animal Challenge list, plus common pipistrelle bats that we saw as we waited for it to get dark enough for lamping. A good night’s work…

Return of the frog

Soon after we moved into our house we built a mini pond, made of a wine barrel. I was delighted when, a few weeks later, we spotted frogs in the pond and around the garden.

But then winter came. I don’t know if you remember, but the winter of 2010 was a particularly cold one (as was 2011 and 2012).  Since that winter we haven’t seen any frogs in our garden. I don’t know if it’s connected, but I wouldn’t be surprised if the cold had had a bad effect on the frog population.

I used the ‘Dragon finder’ app on my phone, developed by the charity Froglife, to identify what species the frog was (through answering a series of simple questions), and report the sighting, together with a photo and GPS location. It was very easy to use, and I’m looking forward to trying it out on some other amphibians and reptiles.

It looks like at least one has returned to our garden. Let’s hope he’s the first of many!
