About Us

Welcome to CPARG - Cambridgeshire and Peterborough's local Amphibian and Reptile Group. ARGs are local, grassroots amphibian and reptile conservation groups spread out throughout the UK, usually organised by county. As a volunteer run group we get up to a whole range of activities – newt surveys, frogspawn counts, advice service, liaison with planning authorities and consultancies, data collection/collation, training, chytrid swabbing, talks and presentations. The opportunities are endless! Events are held on nature reserves and throughout the wider landscape, and while our focus is on Cambridgeshire there are good links between neighbouring ARGs with access to shared away-days, conferences and training available.

We are run by and for volunteers, and we'd like you to join. We're looking for members – people who might be interested in surveying, receiving training, attending talks, sharing their knowledge and experience, or getting involved in any way with amphibian and reptile conservation locally. We're also looking for new committee members to help with the running of the group, most importantly in organising and/or running events (surveys, training, talks, habitat management etc).

Posted on Monday 23rd April, 2018

Although news hasn't been posted on our website for a couple of years now, we have been going strong on WordPress! We moved away from this platform and over to there shortly after out 2016 AGM when our new Communication's Officer then setup a WordPress blog due to the improved functionality over the blog system that is built into our site. Maybe we'll see the return to use using the home system as well but for now you can find out what we've been up to and what's going on here

Volunteers needed for the Big Spawn count!

Posted on Monday 14th March, 2016

It’s that time of year again – soon many garden ponds across the country will be bubbling with hundreds of croaking toads and frogs, and your help is needed to record all that spawn!

Amphibians are commonly found breeding in garden ponds, and data gathered by volunteers is vital in better understanding just how important gardens are for these species. Spawn counts can be used to estimate population sizes and species distributions, an important way of monitoring the status of our amphibians and identifying ways to better conserve them!

It’s really simple, all you have to do is fill in some basic information online; the size and depth of your pond, whether the pond has fish in it, and how much spawn (frog or toad) you can see!


Check out the Fresh Water Habitats website here for more details!

Cambridge toads are on the move!

Posted on Tuesday 8th March, 2016

As the evenings are very slowly getting warmer, toads have been awakening from their sleepy slumber and are now on the move! Their migration from hibernacula to natal spawning ponds can however be lengthy and pretty treacherous. Unfortunately many breeding ponds are now surrounded by an urban environment, making road crossing a necessary, but perilous task.

Toads on Roads and Toad Size are two projects aiming to alleviate and better understand the risk of roads on toad populations. Volunteers collect toads from road sides and help them safely reach their pond for breeding. The level of traffic flow and number of deceased individuals found is also recorded. The Toad Size project involves the measuring of male toads at these road sites to determine whether road mortality is influencing the age structure of populations. Preliminary results show the importance of frequent toad patrols for reducing mortality and enabling a more varied age structure, and the impact of crossing distance on toad size.  Further research is however needed from more sites across the country.

So we at CPARG have just begun Toad Patrol and Toad Size activities for the year, with three outings so far. This is the second year of Toad on Road activities at this specific site, and the first year we have been collecting data for Toad Size.  Our first visit resulted in 152 males safely delivered to the pond. Visit two was on a fairly cold night and resulted in a much more modest number of 19, with 1 of these being scooped out from the depths of a drain, whilst visit number 3 saved 119 toads.

Have you been out helping toads cross roads? Or have you seen sites that could do with some assistance? Let us know! For more information about these projects, check out the website links below, or for more specific Cambridge related queries, contact our Toads on Roads Officer Mark Goodman at

CPARG volunteers help manage ponds for great crested newts (and other amphibians!)

Posted on Tuesday 8th March, 2016

Careful pond and land management is needed to ensure the persistence of amphibian populations in the UK, especially for the Great crested newt (GCN), a species that has seen rapid declines in the past 50 years.  Threats facing amphibians in the UK are largely linked to agricultural intensification, pollution, disease and the introduction of non-native species such as ornamental fish.  Great crested newts have been largely effected by these changes due to their specialist habitat requirements.

The cement-lined ponds at Cambridge city crematorium have been monitored for amphibians since 2013. It was then that CPARG investigated a possible GCN sighting and were pleased to confirm a breeding population of the species, as well as a healthy population of smooth newts.

As appropriate management of remaining GCN populations is important, in early January CPARG volunteers gathered at this GCN site to give the ponds some TLC. An ideal pond for GCN has both extensive submerged and floating aquatic vegetation as well as more open areas for males to woo the ladies with their mating displays. To improve these ponds we therefore dragged out dead vegetation that had been clogging them up, reducing the quality of the habitat and making population monitoring difficult.

We carefully checked and recorded all the material being removed from the pond for life; we found an array of invertebrates including water boatmen and dragonfly larvae, as well as two GCN, three smooth newts and one common frog.

Now the dead vegetation has been removed and the live vegetation trimmed a little, the plants needed for newt egg laying will be able to better flourish and hopefully we’ll see the benefits of our labour later this year during the survey season!


Do you know of any great crested newt populations? Let us know! For more information about how to effectively manage your garden pond for amphibians, check out the Froglife website here.

Frogwatch – Big Garden Spawn Count Volunteers Needed!

Posted on Saturday 28th December, 2013

Do you have a garden pond?  Do you ever see frogs in your garden?


Lots of people would answer yes to at least one of these questions but unfortunately conservation organisations know very little about where frogs are found or how well they’re doing.  But as urban dwellers as well as rural, frogs offer a great opportunity for the public to get face-to-face with wildlife and to contribute to its wellbeing.  For two years the Freshwater Habitats Trust (formerly Pond Conservation) has been running a simple project to make this link. 

Members of the public who are lucky enough to spot frog spawn in their ponds are asked to fill in a simple online record form which then gets logged with others across the country to help answer these questions!  This survey will also pick up on any toadspawn present…but it doesn’t look out for newts so we should still promote either Record Pool or CPERC to capture these records: or

The data from this survey will then be shared with county-based organisations to help fill in some of the gaps on their local frog maps.

This year Cambridgeshire and Peterborough Amphibian and Reptile Group (CPARG) will be promoting this project within our Cambridgeshire patch, contributing both to answering the big questions nationally (e.g. what sort of ponds do frogs like) and providing our partners at CPERC with up-to-date records of breeding frogs.

We’re looking for a team of confident volunteers to send out press releases to local media (online, papers, radio and TV) and to be available for interview to promote this project, CPARG’s other survey opportunities, and amphibian and reptile conservation generally.

If you might be interested in pitching this conservation message to local media please email us on and CC in or call Paul for an informal chat on 07508020437.

This project would suit confident, friendly-sounding people either with or who would like to get some media experience.

Frogs could start breeding as early as February – or even sooner if we have a mild winter/early spring – so we’d like to have people signed up and ready to be interviewed by the end of January if possible.  Good luck spreading the frog-count word!

Dig a Pond!

Sun 13th January, 2013

Sunday 13th January 2013
A secret location in Peterborough! email for address

Come to Hampton, Peterborough, to help repay a dedicated amphibian conservation volunteer by digging her a bigger garden pond. There's already a small 50cm squared pond with a resident frog but we'd like to make a bigger splash and hopefully encourage smooth and crested newts too - and given that she lives next to the world's biggest colony of Great Crested Newts - the Hampton Nature Reserve - it's very likely that newts will colonise. To misquote Field of Dreams "If we build it, they will come". Paul Furnborough will be organising and leading the event so if you've got any pond creation or management questions bring them along and feel free to quiz him. Spades will be provided but if you've got a mattock please do bring it along. Clothes you don't mind getting muddy and weather appropriate are the order of the day. Please bring some lunch, but cakes and hot drinks will be on tap.

Reptile Habitat Management - Scalloping and Bonfire

Sat 26th January, 2013

Saturday 26th January
Hampton Nature Reserve, Peterborough; meeting at Nature's Way - the 'i' on this map:

Join the Froglife volunteer team for a joint day of habitat action! We'll be cutting scallops (D-shaped cuttings) into scrub to create better basking microhabitats for snakes and lizards, before burning the scrub in a bonfire to cook potatoes, bacon, marshmallows or other treats on. 

 Tools and gloves will be provided (though if you've got small hands and gloves which fit well bring those along), as well as hot drinks and biscuits. I'll supply potatoes and if everyone could bring something to share we'll have a treat of a lunch. Wear weather appropriate clothes which you don't mind getting muddy and footwear with decent grip and ankle support.

Please email if you'd like to come and let me know what you'd like to bring for the 'outdoor buffet' (or I can assign/suggest items). 

Paul Furnborough will be organising and leading this event.

TALK: CPARG in Action - Talk for CNHS

Thu 21st February, 2013

Cambridgeshire and Peterborough Amphibian and Reptile Group re-launched in 2012. We are a grassroots volunteer group working to conserve our species through a programme of talks, training events, habitat management and surveys. We are always on the lookout for new members, volunteers and projects - or even just simple garden frog records! This talk will look at the status of Cambridgeshire's 5 native amphibian species and 4 native reptiles, and what you can do to help them.

7:30pm in Room LAB027 on the ground floor of the Lord Ashcroft building of the AngliaRuskin University Campus on East Road. Enter ARU through the main entrance and continue down the corridor; the lecture room is on your left. Tea, coffee and biscuits are provided from 7:00pm. All welcome - non members £1. There is no car parking on site, though some disabled parking may be booked in advance. The Adam & Eve Street car park on the other side of East Road usually has spaces and is free, and there is also nearby on-street parking. The Grafton Centre or Queen Anne Terrace car parks are a five minute walk from the venue.

TALK: Can zoos make a difference for amphibians?

Fri 22nd February, 2013

Ben Tapley, Zoological Society of London

Friday 22 February 2013
13:00 - 14:00
Part II Lecture Theatre, Department of Zoology, Downing Street, Cambridge CB2 3EJ

More than one third of amphibian species are threatened with extinction. Ex situ captive breeding programmes have been set up for a number of amphibian species with mixed success and considerable financial investment. It is time that we step back and evaluate the roles of the modern zoo in such programmes and decide whether or not ex situ conservation breeding programmes are really worth the risk and investment.

Please note this is not a CPARG organised event - we are just helping to advertise it. 

Introduction to Toad Patrolling

Fri 22nd February, 2013

Friday 22nd February
Lakeview Holiday Inn car park, near Histon, Cambridge
5.30-8.00 PM

Join CPARG, CPERC and Froglife at this central Cambridgeshire location to find out more about Toad Patrolling and (subject to toads and weather) have a go yourself!

Please bring some food, a drink, reflective (and/or light coloured) clothing and a torch (head-torch is preferable) if you have one. The finishing time is dependent on toad activity, but will finish by 8pm at the latest.

The Holiday Inn have kindly allowed us free parking, but please Jane know if you plan to come by car. If you are biking/walking you can meet us beside the guided busway for around 5.45pm, but please be careful of the buses.

If you haven’t said you would like to come along to a Toad patrol meeting please let Jane and Rebecca know as there will be further chances for anyone who cannot make this evening, but it would be good to have as many people along as possible.

If you would like help with travel costs/arrangements to this event please let Jane know.

AGM: Amphibian Conservation–A Personal Account; Arnie Cooke

Sat 9th March, 2013

7-9.30 at Wildlife Trust, Cambourne
Saturday 9th March

Please come along and support CPARG at our AGM.

If you'd like to run for committee please email If you have any points you'd like discussed please also email them to Laura.

Event is open to all but only members can vote; you can sign up on the door (£5 for the year).

We're promising a short meeting followed by a unique talk by our very own local expert, Arnie Cooke, titled: Amphibian Conservation - A Personal Account.

Arnie is a well respected local scientist whose talks on a variety of subjects always prove to be popular with his audiences.

His talk looks back on his personal involvement in various studies over many years involving newts and toads including extended scientific studies of various local ponds which provides a wealth of data and an invaluable insight into the ups and downs of the local conservation status of great crested newts and toads.

Committee Member Steve Parnwell said

Arnie’s presentation promises to be thought provoking as well as entertaining. His talk will include a focus on the Toads of Ramsey and Bury and the reasons for their dramatic decline to the point of almost local extinction of the toad population. His other studies carried out over many years go significantly beyond short term snap shots to provide long term overviews of the past, present and possible future of some of the county’s amphibian populations."

Please RSVP to Laura so that we have an idea of numbers. We'll look forward to seeing you there and in the field.

Pond Project

Pond Project

Recent research as identified that urban ponds provide numerous and diverse roles including their ecological function with good quality ponds acting as stepping-stones and refuges for wildlife species within a suriunding of otherwise inhospitable habitat. With this in mind, we are currently looking to find out where all of Cambridge's urban ponds are in an attempt to learn more about the potential dispersal routes of the City's amphibians. It is important to know both where amphibians breed (in terms of public areas) but also where they may also hibernate, which is usually away from breeding ponds and in gardens. Of course amphibians will also breed in garden ponds too and this is useful additional information that we are hoping that you, the constituents of Cambridge will be able to help provide us with. If you're happy for us to make a visit to your garden to survey the pond or give you some advice on how to improve your pond or garden or amphibians then please also let us know of your address. If this is not the case, then please provide us with a grid reference of your pond's location which you can easily find using this free online tool.


Even small garden ponds like the one above can offer plentiful opportunities for amphibians to breed and feed. If you do have a garden pond, the please do get in contact and let us know what species of amphibians you find in it, whether it is stocked with any fish, how old the pond is and how big it is. It is hoped that this information will be used to help inform planning and management of urban areas within Cambridge to benefit amphibians and other wildlife which tend to share the same corridors.

Disclaimer: Any data you share with us will not be shared with any third party groups without your permission first.



CPARG prouds itself with the important conservation research that the group runs, below are short summaries of some of these projects and information on how you can get involved.

Toads on Roads

Toads on Roads is a national initiative which aims to help set up and manage toad crossing across the country. Roads are a huge issue for amphibians, with the main threat being that of cars. Roads bisect amphibian migration routes between breeding ponds and over-wintering sites and so the aim of a toad crossing is to help as many toads as possible make it to the other side of the road. There are a number of registered toad crossings within the county, with one of CPARG's most active ones is in central Cambridge. We are looking for volunteers to help organise other crossings in their towns and villages with CPARG helping to support them where we can. If you'd like to know more, please contact Sarah Coulson.

Cambridge Midwife Toads

Since 2015 CPARG has been monitoring the population of midwife toads (Alytes obstetricans) in central Cambridge. The study first started out as a population assessment but then quickly transformed into a disease monitoring exercise. It was feared that when the toads were introduced that they may have been infected with infectious diseases that are deadly to amphibians. These do not affect humans but they have caused huge declines in species around the world. Fortunately so far  no toads have come back positive for the amphibian chytrid fungus (Batrachochytrium dendrobatidis). We'd like to thank the local residents for allowing us access to their gardens to carry out this important research. If you'd like to know more then please contact Steven Allain.
