Datganiad

Slightly different methodologies were used depending on the site. At Johnstown, and Deeside and Buckley Special Areas of Conservation sites were monitored for the presence of Great Crested Newts eggs, larvae and adults. During the initial monitoring in 2003 all ponds were visited once, during June, where visual inspections took place for Great Crested Newts eggs, lying on substrates near the shoreline. Other bird and fish species were also noted. The main assessment in 2003 consisted of site visits to all ponds at least once between August and September to record presence of larvae and eggs using visual observation, bottle trapping, torch surveying and netting. Environmental conditions within the ponds and other birds and fish species were also recorded. At Halkyn Mountain Special Area of Conservation condition assessments were undertaken where 45 ponds were surveyed where Great Crested Newts had previously been recorded, for eggs, larvae, juveniles and other environmental data.
