decl<strong>in</strong>es occurred <strong>in</strong> the first half of the 20 th<br />

century due to habitat alteration and change as<br />

well as human persecution [12] , but over the last<br />

century, its distribution has changed as a result of<br />

local colonisations and ext<strong>in</strong>ctions [13] .<br />

Habitat preferences and general densities<br />

As a highly adaptable species tolerant of arid conditions,<br />

the jackal occurs <strong>in</strong> a variety of habitats<br />

<strong>in</strong>clud<strong>in</strong>g desert, grassland, wetland, forest, and<br />

agricultural and semi-urban areas, although it is<br />

most common <strong>in</strong> dry, open country [1] . In Europe,<br />

it shows a preference for agricultural areas and<br />

wetlands with adequate cover <strong>in</strong> lower elevations<br />

[12] . Intensively cultivated areas without<br />

cover are not suitable, although human activity<br />

often <strong>in</strong>creases food availability [14] . While subpopulations<br />

comprise fewer than 1,000 adults [12] , the<br />

species is common and numerous where food<br />

and cover are abundant [1] . Viable populations can<br />

exist <strong>in</strong> small areas because the species tolerates<br />

liv<strong>in</strong>g at high densities [14] . In terms of competition<br />

with other carnivores, the jackal is mutually<br />

exclusive with the Grey wolf (Canis lupus) [14–16] ,<br />

dom<strong>in</strong>ates over the Red fox (Vulpes vulpes) [14] ,<br />

and may impact negatively on the Wild cat (Felis<br />

silvestris) [14] .<br />

Legal protection and conservation status<br />

The species is <strong>in</strong>cluded <strong>in</strong> Annex V of the Habitats<br />

Directive <strong>in</strong> the EU [17] and has been protected<br />

<strong>in</strong> Bulgaria s<strong>in</strong>ce 1962 [18] , Italy s<strong>in</strong>ce 1997 [19] and<br />

Slovenia s<strong>in</strong>ce 2004 [16] . In Bulgaria, Croatia<br />

and Hungary, it is actually managed as a game<br />

species [12] . In Greece, a government-led poison<strong>in</strong>g<br />

campaign (with bounty payments until 1981)<br />

was discont<strong>in</strong>ued <strong>in</strong> 1990 [14] . Although there is<br />

a national action plan [14] , the species is neither<br />

officially a game species nor protected [15] . The jackal<br />

is listed as Least Concern both globally and <strong>in</strong><br />

Europe because it is widespread, locally common,<br />

found at high densities where food and cover are<br />

abundant, and highly adaptable and opportunistic<br />

(Table 1). With<strong>in</strong> the EU, it is Near Threatened<br />

because of its small, patchily distributed and<br />

fragmented subpopulations (Table 1). In Greece, it<br />

is listed as Vulnerable.<br />

Abundance and distribution:<br />

current status<br />

The IUCN estimates a global population of over<br />

130,000 <strong>in</strong>dividuals, with a maximum of 42%<br />

occurr<strong>in</strong>g <strong>in</strong> Europe (Table 2). The largest populations<br />

are found <strong>in</strong> Bulgaria (72%), Hungary (13%),<br />

Serbia (9%), Romania (4%) and Greece (2–3%).<br />

In Bulgaria, the Golden jackal is present <strong>in</strong><br />

72% of the country [24] , with the highest densities<br />

<strong>in</strong> the southeast, northeast and central-north [18] .<br />

A 33-fold expansion <strong>in</strong> range between 1962 and<br />

1985 [7] has been attributed to <strong>in</strong>creased food<br />

availability, and legal protection s<strong>in</strong>ce 1962 [25] .<br />

Concurrently, the colonisation rate <strong>in</strong>creased<br />

from 1,150 km 2 to 9,650 km 2 per year [7] . At risk of<br />

ext<strong>in</strong>ction before the 1970s [23] , the population <strong>in</strong><br />

Serbia is now the third largest <strong>in</strong> Europe (Table 2),<br />

and jackals are locally common near the Bulgarian<br />

border and <strong>in</strong> Srem [23] .<br />

The Serbian population orig<strong>in</strong>ated from a small<br />

number of Bulgarian founders and therefore shows<br />

a strong founder effect [26] . It has s<strong>in</strong>ce colonised<br />

Hungary [23] , where it became ext<strong>in</strong>ct <strong>in</strong> the 1940s [18] .<br />

Natural recolonisation started with a few vagrant<br />

animals here <strong>in</strong> 1979 [27] , and a viable population<br />

was established <strong>in</strong> 1991–2 [8] . It is now said to be<br />

spread<strong>in</strong>g “like an <strong>in</strong>vasive species” [8] and numbers<br />

over 7,200 <strong>in</strong>dividuals <strong>in</strong> three regions <strong>in</strong> the<br />
