The same pond was subject to bottle trapping that evening using a total of 15 traps left in the pond for 12 hours. % Should evidence or potential for GCN be identified via the phase 1 preliminary habitat assessment, further newt survey effort may be required. The results were very impressive: 11 GCN (5 males and 6 females). In preliminary trials the Dewsbury trap was found to be more effective at catching newts than traditional bottle trapping methods - where newts were present in a pond the average catch was 12 newts per trap deployed, the maximum catch recorded in a trap was 56.

Bottle trapping was undertaken on all four survey visits. There are different survey methods that are used to locate the presence or absence of GCN, these are; Bottle Trapping, Torching, Netting, Fingertip Search, Egg searching, DNA testing and Habitat Suitability Index (HSI) surveys. GCN are listed as Species of Principal Importance for Nature Conservation in England. This has led to the great crested newt being internationally recognised as vulnerable, threatened or endangered within the 37 different European states that it currently occupies. endobj Bottle Trapping; Torching; Netting; Egg Searches; Natural Refugia Searches; Test for DNA Traces in Water; Bottle Trapping.

(LogOut/ Barry Wright of Dryad Ecology has had many issues about setting bottle traps around pond margins by wading in, potentially getting stuck and disturbing the mud. This information allows the species, population and GCN use to be established.
