Create artificial hibernacula or aestivation sites
A replicated study in 2007–2008 of 10 created hibernacula at three sites in Tyne and Wear, UK (Latham & Knowles 2008) found four amphibian species near hibernacula at two of the sites. In autumn six common frogs Rana temporaria and nine common toads Bufo bufo were found under tiles at two of the sites (with six hibernacula). In spring six great crested newts Triturus cristatus, six smooth newts Triturus vulgaris, seven common toads and two common frogs were caught in pitfall traps near the two hibernacula at one of those sites. Hibernacula were constructed in 2005–2007 by excavating an area 2 x 1 m and 0.5 m deep. This was filled with rubble and covered with tree cuttings and leaves, a permeable geotextile fabric and then soil and grass turf (total height 1 m). In autumn, amphibians were surveyed using six roofing felt tiles (0.5 x 0.5 m) around each hibernaculum. At one site a combination of drift-fencing and pitfall trapping was used to monitor species in spring.
