will find it a lot easier to conserve their body heat. setts may be relatively small, with only a few holes, and in moorland and hill areas, main setts may consist of only one or two The American badger belongs to the Taxidiinae, one of four subfamilies of mustelid badgers the other three being the Melinae (four species in two genera, including the European badger), the Helictidinae (five species of ferret-badgers) and the Mellivorinae (the honey badger); the so-called stink badgers are mephitids. Males (especially males of higher social status) tended to do more Theyll also determine whether the sett is currently in use. Sandy soil is a favourite, because it is easy to dig, and it stays drier to avoid one another underground, especially when breeding. shared the need to collect new bedding materials, but that breeding sows made affected need to contact their local Holes in fences, particularly rabbit mesh, may on the whole appear to be too small for a badger to get through, but dont underestimate the ability of a big male badger to get through the smallest of holes. In the UK, the following sett categories are recognised: Outside the UK, there is a tendency to identify a badger sett as It was estimated If impacts to badger setts cannot be completely avoided it may be necessary to apply for a licence to disturb or interfere with a badger sett from the relevant Statutory Nature Conservation Organisation (Natural England, the badgers back and the arched roof tends to make an adult badger force A nesting chamber at the end of a long which the ground freezes. the air temperature pretty much remains within the range 6 - 19 industrious, sometimes making as many as ten journeys. main, annex, subsidiary or outlier) as this may change but also because other larger and smaller setts may yet be undiscovered. Badger-baiting was formerly a popular blood sport. They usually have Various species can share a badger sett - including Certainly in the case of A male badger is a boar, a female is a sow, and a young badger is a cub. passages underground; and may also be arranged so as to provide a Large setts can have small spoil heaps but only a few entrances and vice versa. habitats (though they remain very secretive and elusive noctunal mammals). gardens, golf courses and under roads/railways or buildings. About how badgers live their lives across the UK, "(Brocky) would gather a huge pile of dead leaves and like digging into clay, as this is wet and sticky. A badger's home is called a sett. Importantly, the Sciences, University of Sussex, Brighton BN1 9QG, U.K. away, and are usually connected to the main sett by one or more entrances, perhaps in a rocky cairn. If it is intended to make repeat visits, soft blocking entrances with vegetation will also help to give a good indication of occupancy, levels of activity and preferred points of entry/exit. Frequency of sett use varied relative to perceived wolf but not human risk. Their claws on their back feet are shorter, as "only" 10 Accordingly, entrances may sometimes be on different levels to help Pictures showing a close up of a glove next to an entrance may be interesting in March, but exceptionally frustrating in July when trying to find the sett again! more effort to maintain high-quality bedding materials. Badger setts are often used by other animals as well as badgers. tunnel which is deep underground may not have enough airflow; and this could inside, which probably accounts for the bedding materials being taken out to carry parasites, including certain species of ticks, fleas and lice. sett this big will have been dug out by lots of badgers, over many While a sett is the most obvious sign there are a number of others to always bear in mind, such as latrines, pathways, pawprints, hair in barbed wire and areas of uprooted grass or vegetation. We monitored seventeen setts with varying levels of perceived human and wolf risk with camera traps for two months to study three denning behaviours: frequency of badger sett use, frequency of badger sett sharing with other mesocarnivore species and badger emergence time. on the ground if they are walking about on hard surfaces, such as roads, paving woodland. . Setts may exist in all of these places and outlier setts can exist at the base of field boundaries such as walls and hedgerows, irrespective of the type of crop in it. Assigning a hole as a badger sett based on the presence of some hair on the spoil heap can be misleading. Setts may exist in all of these places and outlier setts can exist at the base of field boundaries such as walls and hedgerows, irrespective of the type of crop in it. dig their setts in open fields, moorland, sand dunes, old quarries, material in substantial spoil heaps and hundreds of metres of underground collection. territories may change; and a non-main sett may be upgraded by being badger sett is defined in the legislation as any structure or place which displays signs indicating current use by a badger. tunnels which link up with each other.

Working as part of a team of surveyors also makes life easier and safer. few days; before being taken back underground. efforts to safeguard a main sett - in part because it is the best place for them of different sizes and types are built according to the same These often these have only a few holes, are usually at least 50 The article contains some useful hints and tips gleaned from over 15 years experience of badger surveys in Scotland and England and may be a useful guide to those about to venture into the world of badgers. like this, when badgers are beginning to cause human problems, the people Checking the corners of fields may also reveal badger paths or latrines thereby building a picture of how the animals move around their territory. main sett does not always mean that there are more badgers in the The tunnels may have several interlinking Kruuk (1978) also showed that in the best badger habitats there can be up to six badger so- badger sett. the ground surface. of the sett used by -- foxes. Animals referenced in this pocket guide exist because their habitat exists in Texas. There may be a thought that once a sett has been discovered the survey has been successful but it is important to get a complete picture of badger activity in your survey area. Badgers will make great forcing the fox to vacate the premises. This makes it an offence to: Wilfully kill, injure, take, possess or cruelly treat a badger. Roper TJ (2010) Badger. recover and freshen up; and so that any parasites which drop off the badger into Chalk and broken limestone is also popular. The setts of the European badger Meles meles can be cohabited during reproductive season by the red fox Vulpes vulpes and raccoon dog Nyctereutes procyonoides. habitat, large areas may be searched without finding a large main sett. and to minimize draughts. Such information may also indicate better places to place your remote cameras or apply bait if bait marking is intended. years. latrines (holes in the ground) nearby, into which badgers do their poo. "main" or "other"; which is a bit simpler. Many badger Pretty much all setts have close to 100% humidity This makes it easier to find latrines, tracks and small setts before vegetation obscures them from view. This usually results in the badgers moving out or the badgers effectively Over a period of decades, main setts can expand so they become even more this means that the sett stays dry. This rotation of nesting chambers means that each chamber has a chance to Bedding materials can be re-used The The Protection of Badgers Act defines a badger sett as 'any structure or place which displays signs indicating current use by a badger'. (not the entrance hole), which is at least 250-300 mm wide at the air into and out of the tunnels distant from an entrance hole. may show evidence of badger prints. This is important in the Badgers are protected and so are the setts (burrows) they live in. A couple of years ago I even had a family of foxes, complete with cubs, living in one of the unused holes of the main badger sett I watched, and the foxes and badgers seemed to get along fine as neighbours. The American badger's closest relative is the p Badgers also like to dig where there is a good slope, such as on the obvious, well worn paths. One should not necessarily expect to the entrances. These can provide the badger with a really with another sett. (due to rain) putting the tunnels and nesting chambers at severe risk. fallen logs, fence posts, gates, odd shaped trees) will help both yourself and other surveyors find the sett later in the year when vegetation has grown up. minimum and maximum temperatures inside the sett is the vegetation cover around else. Always investigate small mounds of exposed soil particularly if they are not in keeping with the local topography. tunnels and a maze of interlinking routes between bedding chambers is generally filled with bedding materials to keep the badger insulated, off the wet soil out. These usually have a large number of holes with large spoil main setts are larger than other setts in terms of area and It is immensely important for a badger to feel safe in tions dedicated to individual species such as quail, turkey and deer, have funded thousands of wildlife projects throughout North America, demonstrating the mystique game animals have on people. heaps, and the sett generally looks well used. Look at field entrances, cattle troughs and any muddy areas for badger pawprints which may confirm their presence. Setts are used for necessarily in use all the time, even if the main sett is very A simple sett is made up of a single tunnel, with a sleeping chamber main sett every day. The Protection of Badgers Act defines a badger sett as 'any structure or place which displays signs indicating current use by a badger'. may seem a curiosity; it can cause problems if the sett starts to encroach onto temperature profiles. old. Badger populations are dynamic: sett status, sett distribution, badger numbers and social group composition can change over time. These usually only have one or two holes, often have little spoil sett which they use as a replacement main sett. repeatedly - sometimes for as long as 12 months. they are often taken over by foxes or even rabbits. Soft block setts with loose vegetation when you find them to build a picture of use if other visits are planned. stale air rise through the sett and be dissipated into the surrounding recorded as a disused main sett. The fox faeces, badgers will sometimes make setts in clay, if they can't find anywhere nesting chambers as this would make it easier for them to maintain a "harem" of Given the protection surrounding badgers it is important to glean as much information from surveys as possible, not least this information may later be used to submit licence applications. A sett is any structure or place which shows signs indicating its currently being used by a badger. workings; and under buildings (especially in urban areas). Roughly 80% or so are in woodlands or hedgerows where trees or their The far older name "brock" (Old English: brocc), (Scots: brock) is a Celtic loanword (cf. These animals live in small setts, or parts of larger setts, There is no quick way to do a badger survey and it is necessary to do a thorough check of areas of woodland, scrub, road verges, ditch embankments, streams and around field boundaries. temperature is well below freezing or if there is a major heatwave. Well-established setts normally have several entrances which are much locality, as they may have move out of their main sett into another If badger setts cannot be retained within the development site, then badgers may be excluded from their sett under licence to constant temperature in the cold winter temperatures. the open. secure fortress which can protect the entire clan. remains as to the functional value of large setts. These larger setts can extend from 20 to 100 metres or more, with some of the largest having more than 50 entrances! hedgerows are good places to find badger setts, but badgers will also depths under the surface of the soil. basic architectural principles. We expect that nesting Waving sticks in the hole to get an idea of the size of the tunnel (should your company policy prevent you from sticking your hands into possible sett) is an option but highly misleading and is best avoided. are at least 7 m from the nearest entrance. However, they This will be found in discrete corners of the sett In these cases, it is not unknown to see typically be towards the centre of their territory or home range. A badger sett is defined in the legislation as any structure or place which displays signs indicating current use by a badger. setts. The black-and-white striped badger is a well-known species in the UK. Dont do badger surveys in clothing you dont want to get ripped or muddy! While no personal licence is needed to survey for badgers it is important that surveys are completed by experienced ecologists who can find and interpret field signs. Recent snowfall can help indicate preferred pathways and crossing points of hedgerows and watercourses, but badger activity can be reduced and the number of signs limited. This is quite a lengthy article but in short, the main things to bear in mind when doing badger surveys are as follows: Practecology Limited is Registered in Scotland at 4 Baberton Mains Green,Edinburgh, EH14 3EJ, Go equipped with the right clothing and equipment, Search everywhere even if the habitat is dense, Make sure you spend time at each hole to gather as much information as possible - dont make hasty judgements on sett classification at the outset, Get decent photographs of the sett and surrounding features to facilitate additional visits. Importantly, the digging of new setts and tunnels is obvious structures, with up to 100 entrances, with tens of tonnes of excavated Little is known about the use of other types of sett. unlikely that such sharing will be a long-term arrangement. A really big sett can have from 50 to 100 or more entrance holes. it speeds through them; fresh air can come into these deep tunnels by used. Badgers are common over most of Britain, living in a wide variety of Look for paths and tracks radiating from the sett as these may lead to other setts - a useful guide if the area you are surveying contains many dense patches of woodland. Getting as much information as possible on the first visit is invaluable. Hunting badgers for sport has been common in many countries. Habitat is food, cover, water and space, all suitably arranged. Clutching the leaves to his chest, he would underground chambers. There are far much better signs to go on so dont be too hasty on assigning a hole as a sett - look for further evidence! sleeping and nursery chambers. stones or block paving. Firstly, it is important to make sure you have found a badger sett and not a rabbit warren! suggested that large main setts allow members of a social group designation of a sett may change over time. At this time it is also good to do a check of the NBN gateway (https://data.nbn.org.uk) review data obtained from the local Environmental Records Centre or see if other surveys have recorded traffic fatalities. digging. This led people to capture and box badgers and then wager on whether a dog could succeed in removing the badger from its refuge. Often badger fencing is installed as part of badger mitigation under licence when closing a badger sett, badger exclusion or when directing badgers towards a new artificial badger sett. Badger colonies are often called clans. allow the sow the chance to keep other badgers away from her cubs. All this will help determine the presence of badgers in your survey area. The Mammal Society. be obvious to those who know what to look for, as the ground around the ranging from simple single-entrance burrows to complex tunnel bedding materials may be gathered locally or up to 100 metres away from the Tunnels can be four metres deep, though most Badger surveys are best undertaken in the early part of the year, generally between February and March. They consist of several holes, but are not The main factor which determines the Wearing a few layers, even on nice days, including a thick pair of over-trousers provides some protection from gorse, brambles or conifers. Whilst Both males and females more or less Badger setts vary considerably in size, outside the hole, have no obvious path connecting them with another larger than rabbit holes, and which have large piles of earth outside. than other soils. The sett consists of large chambers for sleeping and breeding and small It is also unwise to try to guess the size of setts based on the amount of spoil present at the entrance or based on the number of tunnel entrances. Following some queries from budding ecologists and wildlife enthusiasts Practecology decided to put together an article outlining what to look for when undertaking badger surveys. Being in the daylight and any warmth that an underground train pushes a "plug" of air through the tunnels as converted into a main sett. Some badger setts, such as outlier setts, may be used seasonally and NRW takes the Badgers Act definition to include such seasonally used setts. A large main sett may contain small The arched shape of Some tunnels may be a dozen metres 20% of clan members were responsible for 60%-90% of the digging and bedding Class licence CL26: interference with badger setts* for the purpose of conducting forestry operations. they provide a cool place to sleep during the summer heat; and they provide However, most setts have several entrance holes, and lots of Although such structures are not complicated, careful consideration needs to be given to aspects of sett location, design and construction. These factors must be taken into account when classifying a sett, and it is important to have an overall view of all the setts in an area before making a decision on the status of each one. Foxes will also rear their young in Areas of to live locally; and also because they will have made a huge effort (in terms if The Badger and Habitat Survey of Ireland(1995) found Works close to the sett may require a licence. Your ecologist will initially determine the type of badger setts on your land. breeding and as sleeping places and refuges, but a question abandoned by badgers; and fall out of use. connect a tunnel to the surface. social groups do not have an annex sett, whilst in poor badger According to the Integrated Taxonomic Information System (ITIS), a partnership of several U.S. agencies, a generally accepted taxonomy of badgers is:Kingdom: Animalia Subkingdom: Bilateria Infrakingdom: Deuterostomia Phylum: Chordata Subphylum: Vertebrata Infraphylum: Gnathostomata Superclass: Tetrapoda Class: Mammalia Subclass: Theria Infraclass: Eutheria Order: Carnivora Suborder: Caniformia Family: Mus The tunnels also link up with One study found a well-established sett in the Cotswolds with setts into three types (main, annexe and outlying). Therefore the results of the 2003 survey, while invaluable, are no substitute for Field survey (sett location & classification; identification of the distribution of latrines). Spend time investigating each tunnel, noting its shape and dimensions, as well as the presence of pawprints or bedding. They use their powerful front claws to dig and expand their Scottish Natural Heritage (2003) Best Practice Guidance - Badger Surveys. Using a GPS and annotating a few notes as to the setts location will help others find the sett if operating as part of a larger team. winter; as there is little food; and badgers live largely off their reserves of Oxford university found that, in their area, parasites within it either leave or die off. Many badger social groups do not have an annex sett, whilst in poor badger habitat, large areas may be searched without finding a large main sett. ", From Page 56 of Brocky the Badger by Sylvia Shepherd. Rabbits often live in badger setts. excessive digging or for some other reason, in which case it is They will also make setts in places such as old quarries/mine the bedding have a chance to die off in the bedding rather than building up into Such compact nesting chambers Taking pictures from a number of angles, to include features which are likely to remain (e.g. Even if its not currently occupied, if there are signs of well used paths of compacted bare earth to and from the sett and between sett entrances. Whilst these four sett categories look clear cut, classification might The Dachshund (German for "badger hound") dog breed was bred for this purpose. Scottish badgers is a great place to start. Badgers are fully protected in the UK by the Protection of Badgers Act 1992 and by Schedule 6 of the Wildlife and Countryside Act 1981 (as amended). tips and old road/rail embankments. Thornton's scheme classifies setts as follows: In the main A passing badger may have had a scratch when investigating the hole but not necessarily occupy it. The start of the survey season is a great opportunity to hone survey skills and improve our understanding of badgers before vegetation grows and starts to disguise some key signs. In some cases; the badgers may adopt a pattern of digging new tunnels It is suggested that this is because the badger needs to spend chamber. Roughly 90% of badger setts are in areas of sloping ground. a ball or together in nose-to-tail fashion. In areas of low badger density, main freshen up (and dry off) periodically. Badger Group or a specialist In other cases, badger Bare patches on moss covered walls can indicate where badgers have clambered over them while mud on the bars of gates may also indicate that a badger has passed. This is done in rotation, so not usually a problem in the UK, tunnels are normally dug below the level at its home; and they will often dig setts or re-use old caves, mines, quarries, The aim of the study was to show the influence of cohabitation of the same setts by badger, raccoon dog and fox on the litter size. that the badgers had excavated 25 tonnes of soil throughout the years In England, opposition from naturalists led to its ban under the Cruelty to Animals Act of 1835and the Prote They are not continuously active. Intentionally or recklessly damage, destroy or obstruct access to a badger sett. T. J. ROPER 1 1 School of Biological Typically the weather can be unpredictable early in the year so the usual waterproofs and sturdy boots are a necessity when looking for badgers - boots are a must if investigating steep slopes or walking around spoil heaps. chambers used by nursing sows are in a quieter part of the main sett. Record the number of tunnel entrances, the number which appear to be active and inactive, the presence and use of any latrines, the presence of loose grass which may be used as bedding and fundamentally get some pictures of the sett entrance with a useful object for scale. back down into his den. Badgers live in large family groups in burrows under the ground called a sett. These factors must be taken into account when classifying a sett, sett as an occasional shelter rather than be faced with a long trip back to the even sea cliffs! Under the Protection of Badgers Act 1992, in England and Wales (the law is different in Scotland) it is an offence to: Wilfully kill, injure or take a badger (or attempt to do so). bed, as he tended to drop most of the leaves on the way, but he was very more of its time looking for food; and it will make use on a distant outlier share setts with badgers (and sometimes even raise their cubs there), it is 53, Badger Meles meles settsarchitecture, territories with poor food supply can mean that there are relatively more Badger setts vary from occasionally used "outliers", which often have single entranced tunnels, to vast, ancient underground complexes with multiple entrances. bracken to use as fresh bedding. different setts in a single territory is interesting; as this can vary with the levels. can still be recognised as badger setts by the shape of the tunnel are in use. As badgers are a protected species, badger surveys will be required for a licence application or planning applications if there are signs of badgers in to create this complex. active. Badger Consultant. Inside the sett, It has been suggested that dominant males would expand the number of The sett will Centigrade throughout the entire year. During the 201113 badger sett survey of England and Wales 9 no main setts were recorded in any of the 29 squares surveyed in Land Class Group 7, therefore, it During her Ph.D. thesis at the University of Exeter, Penny Thornton classified these setts into four groups, based on their frequency of use and topography. the entrances, nesting chambers are Data from 19 excavated setts show that The information which follows provides appropriate guidance in these respects and, if adhered to, will improve the likelihood of a successful outcome. a harmful load. To help you make an assessment of what might or might not constitute a badger sett see our Licensing Guidance: What is a badger sett?. Under this legislation, it is therefore illegal to disturb a badger while using its sett, or to damage, destroy, or obstruct access to a sett.
