As I’m sure many of you are aware, we are currently swabbing the Cambridge midwife toads for the presence of a deadly fungus. The results from our 2017 swabbing efforts have recently been published online and they can be found here. With the unusually cold start to the spring, the toads have only just started to become active. Luckily, on our first survey we found toad and we will continue to survey them until the end of the survey season. Keep an eye out here for updates!
This May saw members of CPARG returning to Wandlebury Country Park to continue the monitoring for a second year of an introduced slow worm population within a small area of the site. Two surveys have been carried out so far and will continue throughout the summer and early autumn on a bi-weekly basis.
Already the results are up on numbers found last year, with a maximum count of 15 during the late May survey. These were mostly juvenile reptiles; however, adults were also found, including a mating pair, which is positive sign for the continuation of the population found there.
In addition to the count we are also recording basic biometric information including weight and length (using photographs and ImageJ software) as well as keeping headshots of the adults to help build up a record of the individuals within the study area.

I’m sure that many of our readers from around the Cambridge are will be aware of the annual event that the Cambridge Natural History Society (CNHS) puts on each year, called the Conversazione – the Italian word for conversation. CPARG has been in attendance for the past 3 years now and this year was our biggest and best year yet!
This year, on the final event before it’s centenary (or should that be centenario?), we had the highest number of engagements with members of the public. We also had the largest stand we’ve had at any event, that may have something to do with it – but my personal opinion is down to the moved timing of the event. Usually the Conversazione takes places in July, but this year it took place on the 6th and 7th of April. This is important to our success as this is about the time when people start to notice that amphibians and reptiles are active in their gardens. Hopefully we will have an even bigger stand next year and even more engagements!
If you’d like to help out a similar event then please do get in touch!
CPARG successfully held it’s Annual General Meeting (AGM) on Wednesday 4th April at All Saints Church, Milton. At the meeting a new Toads on Roads Officer and Secretary were elected, due to the previous position holders stepping down from these roles. Treasurer Helen Moore provided everyone in attendance with new’s of CPARG’s finances before Chairman Steven Allain gave a talk about the past 5 years in which CPARG has been active following it’s reformation in November 2012. The talk went down a treat and hopefully a number of new people will be getting involved with CPARG’s activities across the county in the coming year. If you’d like to get involved with any of our events or training then please get in touch!
Some of you may have read a piece published in the Herpetological Bulletin in 2016 written by CPARG’s very own Steven Allain and Liam Smith. The piece of research reported on the mortality of smooth newts on a cycle path along the River Cam where newts were being struck by cyclists on their annual migration to their breeding ponds. Unfortunately the mitigation we planned to implement was impossible due to access rights and getting the right land owner permission. Instead we’ve taken a different approach to address the problem at Riverside Bridge. We’ve installed a small number of signs to let cyclists and other members of the public know that newts are crossing in the area (see below). We’re hoping that this will help to reduce the number of deaths and we will be monitoring the effectiveness of this measure over the next couple of months to see if this intervention is working or not. If you’d like to get involved with the monitoring then please get in touch!

Volunteers are poised to help the once common toad to their breeding pond in east Cambridge. Last year, over 85,000 toads were saved across the country from the dangers of rush hour traffic and gritted roads.
Armed with torches and buckets, volunteers are set to wait a little while longer to scoop up the toads from the roads as they make their way from surrounding gardens and public areas to the very pond they were born in. With a freezing Artic blast forecast next week sending temperatures below zero, it is more than likely the toads will continue to put off their migration until temperatures rise again above 5 degrees Celsius. Something, I’m sure volunteers and toads alike will be looking forward to!

You may remember last week’s post regarding the fact that newts were active at Cambridge City Crematorium despite the cold weather. Due to the relatively warm weather and rain that we’ve been having we felt it was a good idea to check whether or not other amphibians from the other sites we monitor are also awake from their winter slumber. Four sites were checked on the evening of Valentine’s Day in the hope that some amphibians were well on their way to amplexus. Unfortunately some frogs were found but not in great numbers but it still shows that amphibians are starting to move towards their breeding ponds. It would seem we’ve managed to catch things just before the explosion of frogs, toads and newts that appear out of no where in order to breed. Please remember to take care when out at night near ponds not to disturb them and if you do see any, don’t forget to submit sighting reports via RecordPool.
A couple of nights ago myself and a couple of our volunteers made a quick preliminary survey of the ponds at Cambridge City Crematorium. As you may remember they have recently been worked on and the two ponds we stripped out have now been relined. They have also full up with pond water and been fitted with some native vegetation that should start growing when the weather warms up. Something else you’ve probably realised is that the weather hasn’t been the most productive for amphibians but we decided to check the ponds anyway as amphibians have been active and have even started breeding in certain areas of the UK. It was -1°C when we visited the ponds (one of them was even frozen over) but despite this the newts were active!
You’ll have to excuse me for the poor mobile quality photos but it really isn’t what we were expecting. Over 30 smooth newts and 15 great crested newts were seen in the two untouched ponds, with most of them being male. Two two newly renovated ponds had no amphibians present but were slowly being colonised by other pond life. It’s likely that these will be used by frogs and toads to breed in this year due to the lack of predators such as newts (if the newts don’t gradually move in). We’ll keep you updated on future surveys and what we find as well as ways that you can help by getting involved.

On the 2nd December, CPARG Chairman Steven Allain presented a talked titled ‘Investigating the presence of the amphibian chytrid fungus in a non-native species’ at the Joint Scientific Meeting. This was held at the Bournemouth Natural Science Society museum and organised by the Amphibian and Reptile Conservation Trust (ARC) and the British Herpetological Society (BHS). The event is always a very popular one day conference with science and research based presentations from the UK and overseas. Steven presented data from the Cambridge midwife toad project from the past two years including the origins of the project. The talk was very well received and there were a number of questions asked afterwards regarding the future of the project.
You may have seen in an earlier post that we were recently involved with some restoration work of ponds at Cambridge City Crematorium. What I failed to mention before is that we didn’t just rock up and rip out the ponds, months of planning and preparation went into the hard work we did over that weekend. First of all, because the site is known to be home to a large population of great crested newts and because the chances of encountering them was quite high – we had to apply for a conservation licence from Natural England to allow us to disturb them when removing the ponds.
Another issue is where do you put amphibians if you find them? For that the team at Cambridge City Crematorium really outdid themselves. They built the hibernaculum pictured above, make from old paving slabs, turf and some top soil. It is the ideal location for amphibians to hunker down for the winter and hibernate. When we encountered amphibians whilst removing the ponds, if they were in their terrestrial phase they were relocated to this purpose built amphibian hotel. If they were found within the ponds we were working in, they were moved 10 metres to one of the other ponds.
We are hoping to start surveying again in the spring to see how long it takes the newts to recolonise the freshly lined ponds so keep an eye out for our updates!
