There are prehistoric creatures roaming around yourlocal patch - creatures whose ancestors have walked,crawled and slithered since the age of the dinosaurs.They’re called amphibians and reptiles: frogs, toads,newts, snakes and lizards.These species are all around us, in fact many are probably within onehundred metres of where you are right at this moment.This booklet provides information on how to get out there anddiscover more about amphibians and reptiles in the wild.contents1 id guide 2 discover 3 leapgiantforward 4 oneleapGet ready bylearning howto identify theUK’s reptiles andamphibians.pg4Where to lookfor amphibiansand reptilesplus some ofthe threats theyface.pg14Find out abouthelping reptilesand amphibiansin your patch.pg20Getting closerto amphibiansand reptiles.pg26
1 id guide1Slow-wormAnguis fragilisSlow-worms look a bit snake-like but areactually a legless lizard. They have reallyshiny scales that give them a smoothappearance. Slow-worms are usuallybronze or gold coloured; females andjuveniles have dark flanks and, often,a stripe down the back. They can growup to 40cm. These lizards love compostheaps, where invertebrate prey thrives.Look for them on nature reserves,allotments and in gardens.ID tips:1. Shiny bronze or gold appearance2. Lacks a distinct neck3. Can blink (unlike snakes)23Francesca BarkerJules HowardPaul Furnborough/Froglife4
reptilescommon lizard Zootoca viviparaVariable in colour, these lizards areextremely quick - often, all you mightsee is the long tail as it flees into theundergrowth! If possible look out for thepointed snout and the stripes that runalong the flanks. Common lizards grow upto 15cm, nose to tail. Look forthem on nature reserves andon some allotments.1ID tips:1. Long tail that can be dropped if attacked2. Stripes along the back3. Toes with claws4. Pointed snout243Sivi Sivanesan/FroglifeJules HowardTracy Farrer5
1 id guideGrass snake1Natrix natrixLook out for this snake near water (ponds,lakes, rivers, reservoirs, canals). Grasssnakes can grow to 150cm but you’re muchmore likely to see smaller ones. Notice theyellow and/or black markings that form acollar behind the head. They tend to be ashade of green with darker markings alongthe sides of the body. Look for them atnature reserves and in some gardensand allotments (particularly wherethere is freshwater).ID tips:1. Dark bars/spots along the body2. Yellow and black collar3. Circular pupil2Amy HamlettBarry KempRichard Blundell63
reptilesAdderVipera berusThis stocky little snake has adistinctive ‘lightning bolt’ down itsback. They rarely exceed 60cm inlength and can be found aroundpatches of woodland and onheathland. Males are usually greywhereas females and juvenilesare brown. Adders are our onlyvenomous snake. Look for themon nature reserves (they’re veryunlikely to be found in gardens,especially in urban areas).ID tips:1. Dark zig-zag pattern2. V or X on the head3. Red eyes with vertical slit pupil123Tracy FarrerNick PeersTracy Farrer7
1 id guideCommon frogRana temporariaA firm favourite of garden ponds. Look out for stripy legs and a dark ‘eyepatch’. Adults can grow to around 9cm (nose to tail) and are very variablein colour and markings. Frogs lay clumps of spawn in pond shallows.Character: slightly nervy, often leaping at any sign of danger. Likes naturereserves, allotments and gardens and has thrived in urban areas.ID tips:1. Dark patch behind eye2. Smooth, moist skin3. Long, stripy back legs123Sam Taylor/FroglifeSue NorthTerry BrookerSam Taylor/Froglife8
amphibiansCommon toadBufo bufoPrefers crawling to jumping. Look for the dry, ‘warty’ skin and golden eyes.Adults are 5-11cm and usually a shade of brown or green with darkermarkings; variations do occur and juveniles can be very dark or brick red.Toads lay strings of spawn wrapped around pond plants slightly deeperin the water. Character: grumpy-looking! Look out for them in gardens,allotments and nature reserves.ID tips:1. ‘Warty’ skin2. Pair of raised glands on shoulders3. Golden eyes4. Short back legs1324Sam Taylor/FroglifeSivi Sivanesan/FroglifeOliver KratzJohn Heaser9
1 id guideSmooth newtLissotriton vulgaris12A very common newt in gardensand urban areas, rarely reachingmore than 10cm. This specieshas a slightly yellow/orange bellywith black spots and males have awavy crest in spring. Females layindividual eggs which they wrap inplant leaves; newt ‘tadpoles’ havea frill of gills behind the head. Lookout for smooth newts in gardensand on allotments andnature reserves.3ID tips:1. Brown/green smooth skin with stripes and/or spots2. Line or wavy crest down the back3. Yellow/orange belly with black spotsJohn MustoChris QuyFrancesca Barker10
amphibiansPalmate newt1Lissotriton helveticusCan be quite common in the south westof England and Wales. Very similar to thesmooth newt, but males lack a wavy crestin the breeding season. Instead, in springmale palmates develop bulky back feet anda tiny filament appears at the tip of their tail.Females and juveniles can be very difficultto distinguish from smooth newts but theyusually lack spots on the throat. Individualeggs are laid and carefully wrapped inplant leaves. Look out for themin gardens, allotments andnature reserves.234ID tips:1. Tail filament (males in spring)2. Brown/green smooth skin with stripes and/or spots3. Webbed, bulky back feet (males in spring)4. Throat unspottedJules HowardSivi Sivanesan/FroglifeMark Rowe11
1 id guideGreat crested newtTriturus cristatusOur biggest newt. Look for the obvious warty skin(some ‘warts’ are white tipped) and the size is agiveaway (they grow up to 15cm and are quite stocky).Males have a white flash on the tail and a jagged crestthat is much less pronounced outside of the breedingseason. Females and juveniles lack this crest. Great crestednewts have a bright orange belly with irregular black blotches on it.Eggs with a white centre are laid on plant leaves. Look out for them onsome allotments and nature reserves; still considered quite rare(and protected) due to their patchy distribution across the UK.ID tips:11. Jagged crest (males in spring)2. White-tipped warts3. Orange belly withblack blotches4. Stripy toes23Andy MortimoreJules HowardSivi Sivanesan/Froglife124
rare speciesother speciesThe following species are native to the UK but areso rare you are only likely to see them on specialistnature reserves.Smooth snake Coronella austriacaThis slender snake only survives in a few isolatedpatches of heathland in the south of England - it’svery hard to spot! Look out for a heart-shapedmarking on the back of the head.Sand lizard Lacerta agilisThis rare lizard is normally found on sand dunesand heathland nature reserves. Males have aprominent green shimmer to their flanks during thespring breeding season. Sand lizards are relativelychunky lizards, reaching 20cm in length.Natterjack toadEpidalea calamitaLook for the distinctive yellow stripe down the backof the body. These noisy little toads like sand-duneponds and are very rarely found in gardens. Thereare only around 60 populations in the UK.Pool frog Pelophylax lessonaeOnce extinct, but now reintroduced to a single sitein Norfolk. These charismatic little frogs are noisy,making a croak that sounds a little bit like a duckquacking manically!13
To see amphibians and reptiles youhave to know what makes them tick.Here’s a quick guide to some of theplaces you might see them.Natalie Giles2 discoverWhere: Compost heapNatalie GilesWhen: Possible site for overwinteringamphibians and reptiles. Slow-worms maybe found all year. Look out for tiny pencilsized grass snakes in late August andSeptember.Liz Evans-JonesWhy: Both compost bins and compostheaps are used by reptiles and amphibiansas places to hide and places to forage.Many compost heaps are colonised by slowworms, hiding out of sight, whilst takingadvantage of the multitude of invertebrates(particularly slugs and woodlice). If compostheaps are sufficiently big, female grasssnakes may choose to lay their eggs inthem. If you cover your compost heap withold carpet or tarpaulin try lifting this to geta closer look at the creatures inside.Where: Sheds and greenhousesWhen: All year in and around sheds;primarily spring and autumn ingreenhouses.14Lucy Benyon/FroglifeWhy: Amphibians or reptiles may fleeunder a shed if disturbed so could be foundlurking nearby. Frogs, in particular, areknown to live comfortably in greenhouseswhere it stays damp and there are plenty ofbugs and slugs to eat.
Lucy Benyon/FroglifehabitatsWhere: Long grass, flowerbeds orvegetable patchesSam Taylor/FroglifeWhy: All of our amphibians are predatorsand need to seek ample prey to survive.Invertebrates (particularly slugs andsnails) make up the bulk of their diet. Tolook for amphibians and lizards it helps tothink about where invertebrates gather.When: Spring, summer and autumn.Where: Sunbathing spots (open areas)Colin ParryLucy Benyon/FroglifeWhy: Being cold-blooded, the activitiesof snakes and lizards are linked closely tothe weather. If conditions are fairly cool(12-18oC), then they’ll need to get theirbody heat up in order to hunt prey. To dothis they bask in the sun (a good time tospot them). They like to do this nestledagainst something into which they canflee if disturbed (e.g. a dense bit of scrubor under a shed). For this reason you areunlikely to see snakes or lizards baskingin the middle of a flower bed. Instead, lookfor the sunny edges of low-growing thickvegetation.When: Spring and autumn. If it’s toohot, then snakes and lizards will be fullycharged by the sun and you’re less likelyto see them.15
Where: Ponds and water features16Lorraine BakerWhen: Look for breeding amphibians onmild, damp spring nights by torchlight. Insummer, ‘metamorphs’ (newly developedfrogs, toads and newts) make their firstminiature steps out of the pond as fullyformed adults - look for them in vegetationsurrounding the pond but be careful notto step on them! Outside of the breedingseason (May to October) you can expect tosee amphibians up to one kilometre awayfrom their breeding ponds (depending onthe species). Adult newts may hang aroundlonger at the pond in order to hunt foraquatic invertebrates and tadpoles.Lucy Benyon/FroglifeWhy: Frogs, toads and newts all need toreturn to ponds to breed so this is a goodplace to start looking for them. A spot ofpond-dipping can help you find out whatamphibian larvae may be present in apond. Night-time sessions with the torchcan be equally valuable - particularlyfor seeing adult newts courting. Eventhe smallest water feature can becomehome to common species like frogs andsmooth newts. You may see grass snakesvisit ponds, lakes and canals in search ofamphibian prey.Wendy Dowling2 discover
Sam Taylor/FroglifehabitatsWhere: Logs and log pilesWhy: Amphibians may seek protectionfrom predators or extreme weatherby hiding underneath logs; toads canoften be found buried down in soft mud.Decomposing wood is also a great placefor amphibians and slow-worms to huntfor invertebrates.Sivi Sivanesan/FroglifeWhen: All year.Where: Hidey holes - such as in betweenplant pots or behind wheelie binsWhy: Seeking protection from predators.If you carefully look in or around theseareas you might find amphibians orreptiles lurking!Sam Taylor/FroglifeWhen: Spring, summer and autumn.If there is enough protection from theelements amphibians may choose tooverwinter here too.Where: Rockeries and paving slabsLucy Benyon/FroglifeWhy: With their nooks and crannies,rockeries are great places for reptiles andamphibians. There are plenty of baskingopportunities for grass snakes and lizards,with easy escape routes if disturbed.Check under paving slabs for newts ortoads hiding out.When: All year.17
2 discoverNow you know what you’re looking for and where you’ll findit, things should be simple right? Unfortunately not. All of ournative species are facing some serious threats to their futureand once common species are getting more and more scarce.The top three threats facing the UK’s amphibians and reptiles are.Destruction oftheir homesHabitat destruction is oneof the biggest problemsfor all our wildlife. Ashuman habitat hasspread, animals have lostthe woodland, ponds,meadows, heathland andother wild places theycall home. Habitats havealso been broken up byroads and development,so that where one largepopulation lived before,there are now smallerfragmented groups. Allof this makes it harderfor animals to find placesto live, breed and feed,making their lives morefragile. This has been aparticular problem forreptiles, meaning thatsmooth snakes and sandlizards are now incrediblyrare.18RoadsAmphibian diseasesFor amphibians, andcommon toads especially,roads can present a realchallenge. As the roadsbreak up habitats, theysometimes cut hibernationsites off from breedingponds. When the toadswake up in spring andtry to migrate back tothe ponds to breed theyhave to cross these busyroads. It’s estimatedthat 20 tonnes of toadsare killed every year onroads - through beinghit by cars or becomingtrapped by kerbs or drains.Fortunately, some luckytoads have Toad Patrolvolunteers to help. Everyyear, volunteers rescueanything from 35,000 to70,000 toads!There are two diseasesthat are of concern toamphibians and we areworking with the ZoologicalSociety of London onresearch into managingthem. Ranavirus makesfrogs lethargic and verythin, and can lead tothe sad sight of groupsof dead frogs around apond. These mass dieoffs generally happenin hot summer months.Chytridiomycosis (orchytrid for short) is afungus that grows on theskin and causes the animalsto suffocate. Chytrid haswiped out populations offrogs and toads across theworld. Although seriouswhen it does occur, therehave been very few casesin the UK so far. Pleasereport any incidences ofdisease to Froglife.
Jules Howardthreatsunsung heroes?We love them, but we’re aware thatfrogs, toads, newts, lizards andsnakes are often forgotten about.Not only have we had a tendency toundervalue our wildlife in the UK,the creatures Froglife representsare sometimes misunderstood asnasty or dangerous. Sadly, thishas lead to people deliberatelykilling amphibians and reptiles orremoving them from their gardens.19
3 leap forwardWant to get involved in helping amphibians and reptiles but notsure where to start? An urban tail to inspire you.Hidden behind Green Lanes in Haringey,the lush vegetation of Railway FieldsNature Reserve blocks out noise fromthe surrounding streets, creating apeaceful, safe refuge for wildlife. Butthings weren’t always this way.Rebeccca Turpin/FroglifeThe site was originally established as aBritish Rail goods yard in 1868, probablyused mainly for coal. A hundred yearslater, the yard closed and the site wenton to house a community centre forHaringey Social Services. Then, in 1985,it was transformed into a haven forboth wildlife and people and becameHaringey’s first ‘nature park’.20In 1990 the site was declared astatutory Local Nature Reserve and in2004 was awarded Green Flag statusfor achieving and maintaining excellentstandards for a public park.One of the best features of the reserveis the pond, which was created duringthe 1980s in order to encourage wildlifelike frogs, toads and dragonflies on tothe site. Not only is it a fantastic placefor aquatic wildlife but it also attractsbirds and mammals, such as blackbirdsand bats, which come to drink, batheand find food.
case studyThe most frequent visitors to the pondare the blue-tailed damselfly and thecommon frog but below the surfacethere is an array of aquatic insects,from water beetles to dragonfly larvae.Several years ago the water levels inthe pond started to drop beyond whatwas acceptable and experts felt that,unless the pond was repaired, thelocal population of frogs, toads andnewts would disappear. So in 2010,Froglife, with the help of the HeritageLottery Fund, re-lined the pond. Thehealth of the pond was restored almostimmediately.The pond still has to be carefullymanaged and maintained to ensure itssurvival. This is normally done in winterand involves removing fallen leaves andexcess plant growth, plants such as duckweed grow very quickly. The pond, andthe rest of Railway Fields, is maintainedthrough monthly volunteer workdaysorganised by conservation charity BTCV.At only a hectare in area (the size of 21 /2football pitches) this hidden treasureis one of three local nature reservesin Haringey and is a fantastc exampleof how wildlife can flourish in an urbanenvironment.21

how to helpKey: This habitat is used for:1 Hiding2 Hunting3 BreedingAllotments are havens foramphibians and reptiles as theyprovide many of the featuresthese creatures depend on, andall in one place. They provideplaces to sunbathe, find prey,hide and, in many cases, crucialplaces to breed (such as pondsand compost heaps).&trees,hedges12rubsctcveg p ah2p ots&ck eror i es1Why are allotments sogood for amphibians andreptiles?Often, allotments have beenaround for years (sometimes acentury or more), and this meansthat they have had more time tobe colonised by amphibians andreptiles. Allotments have becomea sort of ‘historical safe-house’- a safe place for frogs, toads,newts, snakes and lizards to live,in a landscape that is changing allaround them.Allotments are particularlyimportant places for reptiles,which have very specificrequirements. Because reptilesneed places to bask, thickvegetation in which to hide, andopportunities to find a range ofprey, you’re more likely to findreptiles on allotments than ingardens.23
3 leap forwardrailwayembankmentsgardensThe key to helping reptiles and amphibians, particularly in urbanareas, is linking up habitats. Think about your allotment, gardenor local green space. you can make it a wildlife haven but canthe creatures get there or spread out?What features surround the area?Amphibians and reptiles flourish whenthere’s lots of different habitats thatthey like, all in one area. Basically you’remore likely to see amphibians andreptiles in places that are surroundedby other ‘frog-friendly’ habitats.For instance, if an allotment or gardenis surrounded by other gardens (good24foraging habitat for amphibians) andwoodland, then expect to see moreamphibians and reptiles here than on asite that’s surrounded by roads, fencesand concrete.Generally speaking, as well as gardens,woodlands and allotments, amphibiansand reptiles may be attracted toheathland, hedgerows, cemetaries,
how to helpallotmentsparkscemetarieshedgesparks and general overgrownwasteland. If your garden or allotmentis surrounded by lots of these features,and they are well connected, thenodds-on you’ll have good populations ofamphibians and reptiles.Railway embankments, like allotments,have often been present for morethan a century meaning that reptilepopulations locally may have stayedrelatively untouched as the countrysidehas changed around them.South-facing slopes, such as railwayembankments are a featureparticularly associated with reptiles.Because these embankments areoften at an incline this provides lotsof opportunities for basking. Reptilestend to use railway embankments ascorridors between sites.If your allotment, garden or local naturereserve has a railway embankmentnearby it might turn out to be a reptilehotspot.25

The free swimming larvae, called tadpoles in toads and frogs, breathe through gills. Adult amphibians breathe with lungs as well as through their skin.
