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 />
