"The world of badgers is in some ways analogous with the human world. Like us, their behaviour is greatly influenced by their need for homes and living space, and being social like we are, they too have their problems of learning how to live together ..... and with us"
Ernest Neal


Each badger clan has its own area - called a territory or a home range. There is a lot of discussion about whether these terms have the same meaning, but they are different concepts.

  • The home range is that area of land which is used by any or all members of the group in the course of their normal activities.
  • The territory, relates to the area of land which is used by the badgers and which the clan or the dominant boar would defend. It is quite common that a particular individual badger uses only a part of the home range.
  • Accordingly, there may be areas well away from a sett which clan members use but do not defend; but there are areas nearer the sett which would be fiercely defended. Badgers may be less likely to defend peripheral areas if there is a great food abundance either generally or in those specific areas. They may be proportionally more likely to defend areas in which their females maintain a territorial presence; as dominant boars would  not be happy to see one of his females mated by neighbour or a stranger.

Generally nowadays, many people talk only about the territory of a badger group; when they in fact mean the home range.

The home range contains only one main badger sett and one or more non-main setts, as well as a variety of places where the badgers can find regular food. The badgers have their own pathways, linking their setts and feeding areas.

The size of the home range will vary depending on the local habitat, food availability, landscape features and local badger density. A home range may be as small as 30 hectares in a good rural habitat, but as large as 300 hectares in a poor habitat. On average a territory may be around 50 hectares, with main setts normally at least 500 metres apart. The key exception here is in urban areas of cities/town, where territories can be as small as 5 hectares, IF they can obtain enough food from bird tables, food waste or artificial feeding in suburban gardens.

If a badger from one clan wanders into the territory of another clan, there may be trouble. If the incoming badger is discovered, a fight may break out. As badgers have very powerful jaws and sharp teeth, nasty injuries can be inflicted when they fight. A badger which gets into a fight with another badger may well end up with a wound on its rump, just above the tail.

Boars (males) are more territorial than females, and mark territorial boundaries more often than females. As well as the need to mark the territory, males may also stray into neighbouring territories looking for receptive females. Accordingly, males are less likely to tolerate other males coming into their territory; as other males may be a threat, whereas other females may become an opportunity.

The desire of male badgers to breed means that there is a greater degree of territorial marking (and other behaviour) in the period from January to May; with a peak in the main mating season from February through to May.

Fights can also take place between members of the same clan. This usually happens when there are too many badgers in the clan, and not enough food to go round; or when badgers are trying to fight their way up the pecking order to become a dominant boar or sow. If proper fights break out, the younger animals may then be forced out the clan and have to find somewhere else to live. This may be in a small sett on the edge of the territory, or in another territory altogether.

In fact, badgers are a little unusual in having such a strong family group or clan which reigns supreme over the territory. The clan will often take greats pains to try and cover most of the territory each night, walking on most of their regular well-worn pathways. They may well take the opportunity to scent mark and defecate on the boundaries which mark the edge of their territory. It is believed that the clan does this, because it collectively has the time to mark out and protect its territory. A lone badger would not have enough time to scent-mark its territory and gather and eat enough food to enable its long-term survival.

A territory can vary in size and shape, depending on many factors. These will include the availability of food, the ability to gather that food, the pressures on the territory from other badger clans, physical barriers or hardships (like wide rivers, railways, motorways and busy trunk roads). A particular territory will be sized so as to provide a large enough regular food supply for the clan. Accordingly, "good" territories, such as those with large amounts of regularly cut grassland may be relatively smaller. Territories which have a less good food supply (such as those in rough moorland or steep craggy mountainside areas, may be much larger in relative terms.

In an area which provides a very poor habitat, the territory may be as large as 300 hectares.

In areas where there is a high badger density, they will sleep in the main sett for at least 90% of the days. However, in areas where food is relatively scarce, badgers will need a larger territory in which to find enough to eat. In those cases, badgers may have very large territories; and may move from sett to sett from one night to another.

Although badgers can and do climb, they can be deterred by the presence of large obstructions. For this reason, it is often the case that badger territories follow dominant physical landscape features, such as walls, hedgerows, fences, busy roads, railways and wide waterways. You will often find well-used badger paths which approach the boundary; and then result in marking; with examples of latrines (dung pits), scent marking/musking, scratch marks and urine. A line of latrines on both sides of a main landscape feature may be a good indicator of a territorial boundary.

Bait-marking is a widely used technique for determining the territorial configuration of social groups of the European Badger (Meles meles). Applications include ecological research and applied wildlife management problems. Bait laced with indigestible plastic pellets is fed to Badger social groups, and the markers are identified in subsequent defecations. Feeding a unique colour and/or shape of pellet to each social group allows the origin of droppings to be assigned. This method is particularly suited to Badgers because they mark their territorial boundaries with communal latrines. In this paper the technique is described in detail for the first time in the scientific literature. Data from sequential visits to latrines during the survey period showed significant short-term variation in the number of marked droppings counted at individual latrines. This suggests that counting marked droppings may be of limited value in quantifying defecation rates and latrine use. However, counts of droppings at latrines could be useful if repeated over time and/or grouped into broad categories. Bait marking does provide reliable data for the estimation of territorial boundaries between Badger groups, although it is labour intensive and time-consuming, with the best results obtained by experienced fieldworkers.

Factors affecting population density, group size and territory size of the European badger, Meles meles

This paper discusses the relationship between the distribution and biomass of the main prey of European badgers, Meles meles and the badgers group size, territory size and population density. The distribution of areas rich in earthworms, Lumbricus spp., is correlated with badger range size, whilst badger group size increases with the biomass of worms per badger territory and badger density increases with overall worm biomass. Regulation of badger density in an area is likely to take place through regulation of group size, in the absence of other factors such as persecution and lack of suitable sett-sites.
