Great Crested Newt Special Area of Conservation (SAC) Monitoring Data
Natural Resources Wales
Description
Natural Resources Wales monitoring data for Great Crested Newts on Special Areas of Conservation (SACs) in Wales where Great Crested Newts (GCN) are a special feature. Includes records for other amphibians.
Currently the monitoring covers three sites in North East Wales:
1) Johnstown Newt Sites SAC
2) Deeside and Buckley Newt Sites SAC
3) Halkyn Mountain/Mynydd Helygain SAC
The reports also include collations of historical records however, these are not included here as they are not owned by NRW and are therefore omitted from this published dataset.
Geographic Description
The dataset currently only contains records from SACs in North East Wales, however when further sites are monitored geographical coverage will be extended.
Purpose
The purpose of this data capture was to assess the condition of designated SAC features based on site-specific performance indicators, and to record aspects of their management, both as an aid to management decisions and for reporting at a variety of scales.
Data quality
Monitoring carried out by experienced contractors.
Methods
Johnstown and Deeside & Buckley SACs.
Sites were monitored by contractor Jan Wilkinson, for presence of GCN eggs, larvae and adults.
a) 2003 initial monitoring: All ponds visited once in June, to carry out visual inspection for GCN eggs on laying substrates near shore. Other bird and fish species noted.
b) 2003 main assessment: All ponds visited at least once, in most cases twice, during Aug-Sept, to record presence of larvae/efts using visual observation, bottle trapping, torch surveying and netting. Environmental conditions within pond and other waterfowl and fish species also noted.
Halkyn Mountain SAC
Sites were monitored by contractor Young Associates, as follows:
a) Survey of 45 ponds, where GCN had previously been recorded, for eggs, larvae and juveniles and other environmental data. 31st May and 1st June 2005 with a return visit in Aug 2005.
