About Us

DARN is a network of people in Dorset interested in our native reptiles and amphibians. Its purpose is to promote the conservation, recording and appreciation of native amphibians and reptiles in the county of Dorset. DARN serves as a means of communication between volunteers, professionals and the general public. DARN members pay an annual fee of £6 and then when suitably trained they can  take part in our widespread reptile surveys. These can be viewed once reptile surveyor status has been achieved. DARN is also running the SliC project - Slow-worms in Churchyards. We have rare reptile survey sites on FE and MOD land and we are continually adding new transects as we expand our activities across the county. DARN also monitors non-native species to try to assess any impact on our native species.  

Dorset has 12 of the UK's 13 native amphibian and reptile species, and a handful of non-native species. Its internationally-important heathlands are famous as national strongholds for the rare reptiles - Sand Lizard and Smooth Snake - and southwest England's only populations of our second-rarest amphibian, the Natterjack Toad. With such an important wildlife heritage in Dorset, several wildlife NGOs have their headquarters in the county, including the Amphibian and Reptile Conservation Trust (ARC). Together with the various statutory bodies and local authorities, this means Dorset has many wildlife professionals. DARN aims to form a link between all these people, and to nurture an appreciation among the general public for our herpetofaunal friends.

Sheila Dyason is Chair of DARN. DARN Dispatches is a newsletter that is produced at least twice a year, telling you of news, items of interest, and projects to get involved in. Dorset is home to some of the most important reptile and amphibian populations in the country, with a high concentration of protected sites, conservation activities and research projects. There are endless opportunities for helping out by volunteering, and there are already many volunteers in the county who give their time towards projects helping to conserve our herpetofauna, and raise awareness.

The History of the DARN Group

DARN was set up as a surveying and recording group on 30/01/2020. Previously it had been an email and facebook group.

The founding members were Sheila Dyason as Chair, Catherine Dyason as Secretary, Pete Gillatt as Treasurer.

The Group started with rare reptile sites which Sheila had arranged with Forestry England to survey as part of HIWARG – the Hampshire Group. Some of them had been set up and monitored by David Tamarind who sadly died recently. There were not any widespread species surveys for members to get involved with so Sheila set up the SliC Project – Slow-worms in Churchyards - as a way to get members involved in surveying.  

As of July 2021 DARN has 8 widespread reptile transects set up in north Dorset and three more rare reptile transects including one on MOD land. DARN is working with land owners and managers such as Forestry England, Butterfly Conservation, the Dorset Wildlife Trust, the MOD, church communities and private land owners.




DARN Dispatches 2

Posted on Tuesday 30th June, 2020

Hello again!

I hope you’re all keeping safe and well.

Naturally, not a lot of DARN surveys have been carried out over the past few months but we have just started again in Ringwood Forest. Nevertheless, throughout the lockdown, some records were still coming into the DARN database – which is fantastic! So, thank you, everyone!

If you have any records, historic ones are fine as well, add them to Casual Sightings on the DARN website:  or on Record Pool: or email the details to:

The recent fires in Dorset and Hampshire, some deliberate and others through thoughtlessness, are sad and frustrating. Some people just don’t care about our precious wildlife. How species manage to survive is a miracle. On the other hand, because reptiles are difficult to find, some people do not realise they are in the area.

Amphibian survey training is just beginning in Hampshire. If you are interested in amphibian or reptile survey training then make sure that your DARN membership is up to date and for insurance purposes, that you have completed the Volunteer Worker’s Agreement (VWA) and we will add you to the list.

Just before lockdown I was about to set up transects at Motcombe and I was investigating sites in the Purbeck area. If you have any other suggestions for sites, maybe just 3 or 4 tins near where you live, just let me know and we can set it up.

Pete Gillatt took these fabulous photos earlier in the month in Dorset – thanks Pete! Pete has a rare reptile licence and was surveying under that licence.

Posted on Saturday 7th March, 2020

I hope you have all had a good hibernation and are fully refreshed and ready for an exciting new survey season!

DARN now has a bank account and Paypal operational so if you would like to pay the annual £6 subscription or donate to DARN then this is now possible on

the Home page.


On Sunday 26th April there will be an opportunity to undertake reptile survey training at a joint event with HIWARG (Hampshire and Isle of Wight Amphibian

and Reptile Group) and another partner, in the New Forest. If you are interested in this then email

and further details will be sent out as preparations are finalised. You will need to be a DARN member and have completed the VWA (volunteer worker's

agreement) which you are prompted to do once you join. This is so that you are covered by ARGUK's insurance.

DARN has 9 reptile transects in Ringwood Forest. More survey sites are needed so if you know of an area that needs surveying or a landowner who might

be interested in knowing what reptiles are on their land, then email

with the details. Similarly, email if you know of any churchyards or cemeteries with wildlife areas that may have Slow-worms. This is another area I would like

to develop.

Any spawn or animal sightings can be added on the Home page, Record a sighting, or if you are already an amphibian or reptile surveyor on the on-line

recording page.

Any ideas or questions just email 

I look forward to hearing from you and seeing some of you at the reptile survey training.

Best wishes

New Year - New Chair

Posted on Wednesday 29th January, 2020

Sheila Dyason, Secretary of HIWARG (Hampshire and Isle of Wight Amphibian and Reptile Group) is the new Chair of DARN. Chris has done a fantastic job over many years but he does not currently have the time to take the Group forward but we thank him for all his hard work and luckily he is going to continue as a DARN member.

Sheila lives in Dorset near the Hampshire border and hence her interest in both Groups. She has previously surveyed for reptiles for the Cyril Diver Project and for ARC's New Forest Smooth Snake Project which has now morphed into the Snakes in the Heather Project. She has a GCN licence and a Rare Reptiles licence. This year she will be doing some work with Natterjack Toads at Hengistbury Head. She looks forward to meeting and working with land managers, volunteers, ecologists and other conservationists across Dorset.
