Wirral Parks and Open Spaces Section Ponds - How to pond dip Equipment you will need Pond net with a fine White plastic tray mesh filled with pond water Microspector - a clear plastic Pond identification key container with a magnifyer on top Pond dipping method 1.Holding the net vertically sweep it through the water in a figure of eight shape. Try not to disturb the mud at the bottom of the pond 2. Sweep the net through the vegetation to dislodge any animals which might be hiding there. 3. Bring the net out of the water and put the contents into the plastic tray filled with pond water. Turn the net inside out in the water and poke out the corners to ensure all creatures caught fall into the tray. Sort through any pond weed which might have collected to carefully remove any creatures into the tray but put most of the weed back in the net and return it to the pond straight away. 5. Using the identification key find out what has been caught. Try to find out more information about the pond life in the pond from pond information packs, books and leaflets. 4. Do not leave pond weed on the ground. A small amount of pond weed may be left in the tray to provide some cover for the creatures to hide among. Adults and older careful children may use a spoon to gently catch a creature and put it into a microspector for clear inspection. Small children should not be allowed to do this as damage can be caused to the creatures through lack of care.

They are often brown or grey with darker blobs, but are sometimes more colourful in shades of yellow or orange. All frogs have a distinct brown patch behind each eye which actually surrounds the ear drum and is not present in toads. Frog noses are more pointed than that of toads and the hump on the back is more pronounced. When disturbed frogs will leap away to safety and sometimes if they are alarmed they utter a weird shriek. Habitats In summer they are often found in long grass. Habitats include, open pasture, woodland edge and gardens. Frogs like pools with shallow edges to lay their spawn in preferably without fish since these will eat most of their tadpoles. Frogs choose their breeding ponds on the basis of which type of algae is growing in them as this is their tadpoles main food source. Status Common frogs are found throughout Britain and Northern Europe. The only protection given to common frogs is that it is illegal to sell them. Common toads Identification - they are plump warty creatures with uniform brown grey background colours. They tend to waddle or crawl along although they can make a few feeble hops. They have short back legs when compared with a frog. Habitats Toads are usually found under things such as logs and stones. They are more fussy than the frog in their choice of breeding pools. Toads prefer deeper pools Status and do not mind the presence of fish as their tadpoles are equipped early in life Widespread distribution in with a range of unpleasant tasting poisons that quickly persuade fish to leave Britain, Europe and across them alone. Asia. The only protection Natterjack toads afforded common toads is that Identification - they are small warty toads it is illegal to sell them. with pale skin and a distinctive yellow stripe which runs the length of the body from snout to vent. The function of this stripe is not precisely known but it could be for Habitats camouflage. They have short back legs and They live in sandy places under rubbish or in little burrows. get around by running. Males have loud Natterjacks only come to water to breed and they like very voices which can be heard up to a mile away. shallow sandy bottomed pools with hardly any vegetation. Status These pools heat up quickly which speeds up metamorphosis, Natterjack toads are rare and specially but it also means that they dry up easily which can lead to protected. They only occur in sand dunes in mass tadpole death. North West England and south west Scotland, with smaller colonies in East Anglia and southern England. Wirral Parks and Open Spaces Section Ponds - Amphibians Identification and habitats - newts Habitats Newts tend to prefer deep ponds with more vegetation in them as they lay their eggs on the underside of leaves. They do not like ponds which have fish as their tadpoles are easy prey. Newts only require the pond for breeding purposes, preferring to spend most of their time hiding in long grass or hiding beneath stones and logs. On damp nights they come out to hunt worms, slugs and other minibeasts. During the winter, newts can be found under stones and logs and in other damp sheltered places. They are not fully hibernating for if a period of warmer weather occurs they can venture out and find food. Newts are sometimes mistaken for lizards because they are found primarily on dry land. Status Smooth newts have no special protection afforded to them, although it is illegal to sell live or dead specimens. Great crested newts have full protection from the Wildlife and Countryside Act whereby their habitat may not be disturbed or damaged. They may not be intentionally killed, injured or taken from their habitats. It is also illegal to sell or to be in possession of any live or dead specimens Identification Smooth Newts are about 75mm long. They have yellow/orange bellies with a number of dark spots. In the breeding season, males have a continuous high wavy crest on their back and tail. Their fingers and toes are not webbed. Female smooth newts are very different in appearance to the males and they never have a crest and are usually duller in colour. These newts are entirely carnivorous and eat anything from water shrimps to frog tadpoles. Identification Great Crested Newts are much bigger than the other species of newts at 150mm in length and are more heavily built. They have warty skins which produce poisons just like in toads. The adult is dark in colour and from above looks almost black when in the water. Underneath both sexes are beautifully marked with yellow- orange and black blotches. Males have high jagged crests on their back. This crest is not continuous as it dips towards the end of the body by the start of the tail. There is a silver stripe along their tail and tiny white spots can be seen on their backs. Wirral Parks and Open Spaces Section Ponds -Amphibians Life cycles Frogs and toads 1.
