Welsh Sand Lizard (Lacerta agilis) and Natterjack Toad (Epidalea calamita) Recovery Project 2011-2014
This dataset comprises of field observations of adults, spawn strings and habitat conditions for Natterjack Toads (Epidalea calamita) and Sand Lizards (Lacerta agilis). The data was collected for an assessment of current populations at re-introduction sites. Natterjack Toad (Epidalea calamita) Natterjack toad breeding activity was recorded in all three sections of Gronant Dunes and Talacre Warren Site of Special Scientific Interest (SSSI) in 2013. The breeding pools were monitored and the data presented to the annual recorders meetings. A project to establish natterjacks at the Old Colliery site was started in 2009, but the initial translocation was unsuccessful. In 2010, Environment Agency Wales created about 30 pools at the site and further modified them for natterjacks in 2012. Their hydro-periodism was observed during 2013 and the translocation programme will start afresh in 2014. In 2011 a total of only 168 spawn strings were recorded in Wales, whereas in 2012 was a record year was observed with 454 spawn strings counted. The relatively low spawn count in 2011 can be attributable to the dry weather that shortened the breeding season. In stark contrast to a dry start, 2012 became very wet and the natterjacks had a long and successful breeding season. The total recorded in 2012 was the highest ever, a reflection of the strengthening population, good weather conditions and an increase in the number of pools at Talacre through the Million Ponds Project funding. The population and breeding range is likely to be at its highest level since the re-introduction project began in 1995. Sand Lizard (Lacerta agilis) The sand lizard (Lacerta agilis) was formerly known from dune systems in north and west Wales. These known populations were lost due to erosion, development and increased public pressure. Natural Resources Wales (formerly CCW) has continued to provide funds to ascertain the status of the species via site monitoring and provided funding for captive breeding and translocation programmes, to restore the species former range. Monitoring at all of the translocation sites continued though was constrained by poor spring weather in 2013. Positive results of both adults and juveniles have been obtained at all established translocation sites.

The majority of the 2013 sand lizard monitoring data has been entered into the ARC and Cofnod databases, though we have not yet received all of the records. The report collating information on further potential sand lizard translocations remains based on HCT, 2007. Short term \priority\" options included both Newborough Warren National Nature Reserve (NNR) and Aberffraw Site of Special Scientific Interest (SSSI)."
