About Us

Hertfordshire Amphibian and Reptile Group (HertsARG) is a new organisation established to involve the public in the conservation and recording of reptiles and amphibians. We are developing links with other local conservation groups in order to complete projects and develop records for the County. It is anticipated that we will affiliate to ARG UK and work closely with the County recorder to develop these aims.

Over the coming months we hope there will be news of a number of interesting and valuable conservation and research projects. Should you wish to become involved, or simply to be kept updated of progress, please email your contact details to davewillisbhs@yahoo.co.uk.

If you have any questions or ideas for future work, or know of a site you think may be of interest, let us know!

Survey season is upon us, so (perhaps when the weather sorts itself out) we need to get out there and get some records in and projects planned. If you would like to get involved, please email me.

February meeting

Posted on Tuesday 5th February, 2013
Lots to talk about this month, as this will be the start of the season. If anyone fancies coming out for an evening’s newt watching/counting in the Hatfield area this weekend, let us know! Unfortunately, it is uncertain as to whether Gail Austin-Price from KRAG can join us. However, Jonathan Cranfield from EssexARG might step into her spot.
See the attached flyer. Over the coming season we are going to get very involved with this, and over the next few weeks, we shall be visiting known toad sites. Please can we have names and contact details for patrols/groups.
Newt and Comon Lizard sites
There are a few sites needed for populations of Newts. We will discuss in more detail, but one is a garden rescue, the other a potential new Great Crested Newt Site, specially created. Additionally, it looks as though we will be montioring a translocated population of Common Lizards in the region.
Record Pool
The ARG UK “Record Pool” has been created in order to create a nationwide distribution map. Check out the website: http://recordpool.org.uk/
Thanks are due to Scott Townend who produced the new logo, which will be unveiled at the meeting. It is great, and should shortly be adorning the website and clothing available to buy online. Should anyone else have any ideas as to how we can raise the profile of the group, please share!

First meeting of 2013

Posted on Thursday 10th January, 2013

Has it really been that long ?!

Posted on Thursday 13th December, 2012

Hello all,

Apologies it has been so quiet for so long, but things have been busy. There have been a few talks undertaken (Bishops Stortford Natural History Society and Hertfordshire Natural history Society). 2013 looks set to be our busiest season yet! Our next meeting will be on the second Friday of January 2013, when we will be getting ready for the upcoming survey season. Watch this space, which will be a lot busier than it has in 2012!

April 2012 update

Posted on Sunday 8th April, 2012

HertsARG April 2012.

Happy Easter! Many thanks to everyone who came to Bayfordbury Field Centre last week, and thanks to the University of Hertfordshire for letting us use the facilities again. Photos of the day are up on the website. There are a few dates for your diary, some good news and a request for assistance.

Great Crested Newt evening

Depending on weather, Will Atkins (LEHART) will be leading a tour of the ponds of Coppetts Wood in Barnet. These ponds are a great example of conservation volunteer effort and support a thriving population of Great Crested Newts. This will take place over the next fortnight and Will is going to send out notification 2-4 days in advance. This will give you opportunity to see some of the theory discussed last week put into practice.

Wildlife Trust Events

There are a number of Herp-focussed Wildlife Trust events coming up. Some highlights;

Monday 16th April 2012 6-9pm. Herp Surveying in the Colne Valley. Iver Heath SL0 0EB. Contact Jennifer Gilbert (07909 914962) or wildlifetrust@hillingdon.gov.uk.

Saturday 12th May 2012. 10am. Reptiles and rare plants, Balls Wood, Hertford.

Hertfordshire Toads and Toad Crossing projects

There is growing national concern regarding the numbers of Common Toads (Bufo bufo). There are a number of locations in Hertfordshire at which “toad crossings” used to take place with volunteers helping toads to cross roads en route to their spawning ponds. The following are, at least historically, known to be toad crossing sites;

Hollycross Road, Amwell Great Wymondley/Willian

Bourne End, Pix Farm Road Westmill

Mangrove Road/Lord Street, Hertford/Hoddesdon Panshanger/Mimram Valley

Sparrowhall Farm, Waterend Lane Wilstone Reservoir

Stevenage Rd., Letchworth

Sperberry Hill, St Ippolitts

If anyone lives near any of these places, or knows of other toad locations, please contact me or our Conservation Officer, Michelle Bullock (michelle.bullock@live.co.uk) as we will be organising a few of these and hopefully getting a handle on any decline in Hertfordshire.

HertsARG field days

A trip to the Alpine Meadow Nature Reserve, Berkhamsted ,home to Common Lizards, Slow Worms and Grass Snakes is planned for the next 3-4 weeks. This will be dependent upon weather, and further notifications will follow.
