Surveying PEA

Native species of frog found in the UK are:

  • Common Frog (Rana temporaria)
  • Pool Frog – Pelophylax lessonae
  • This is extended to include the potential for a site to contain supported protected species.

Alien Frogs found in the UK are:

  • Pool Frog (Rana lessonae)
  • Edible Frog (Rana esculenta)
  • Marsh Frog – Pelophylax ridibunda
Breeding season of Common Frog:
  • Emerging from hibernation in late February
  • Spawning varies in different parts of the country depending on how warm it is
  • Can run from January through to the end of March but usually starts in March
  • Males croak during the breeding season
  • Males grip the females for days
  • Female will lay up to 2000 eggs, surrounded by a layer of jelly (known as frogspawn) in the water
  • Successful male fertilises eggs immediately in the water
  • Frogs do not feed during breeding season

Unlike toads, common frogs can breathe through their skin as well as their lungs; they have moist skin. These frogs are  largely terrestrial, when active they can be found in meadows, woodlands and gardens. They eat  invertebrates such as insects, snails, worms and slugs. Adults only feed on land. Younger frogs will feed on land and in water. Tadpoles feed on algae.  In winter they  hibernate and can often be found in compost heaps, piles of  logs and stones.
