Of two toad species found in Scotland, only the common toad is present in the Lothians (the other is the natterjack, a much rarer animal found at a handful of sites in SW Scotland). It is easily distinguished from the frog by its darker coloration, bumpy or granular skin and more rounded snout. It also walks or hops rather than jumping or leaping. Toads are more terrestrial than frogs, only entering the water briefly in spring to breed. Eggs are laid in long strings of jelly rather than clumps – a sure indication of its presence at a site. Toads present a greater conservation worry than frogs as they are more selective in their choice of where to breed and require larger, deeper waterbodies, making most garden ponds unsuitable. Although toads have probably lost some habitat in the area, Edinburgh still has some excellent sites where thousands of toads converge every spring to breed. Toads are now listed as a UK Biodiversity Action Plan (BAP) species.
