A common and widespread species. Declines are occurring in the northernmost part of the range, but in the southern part it is abundant and considered a pest species. Consequently it is assessed as Least Concern.

Geographic Range [top]

Range Description:Glis glis has a global distribution that extends across Europe and through northern Turkey to the Caucasus, northern Iran and Turkmenistan. In the Mediterranean, it occurs from northern Spain through central and eastern Europe, as far as Latvia in the north and Italy and the Balkan Peninsula in the south (Kryštufek 1999). It is found on a number of Mediterranean islands, but the population in the British Isles is the result of an introduction in 1902 (Kryštufek 1999, Battersby 2005). It is recorded from sea level to 2,000 m.
Countries occurrence:
Albania; Austria; Azerbaijan; Belarus; Belgium; Bosnia and Herzegovina; Bulgaria; Croatia; Czech Republic; France; Georgia; Germany; Greece; Hungary; Iran, Islamic Republic of; Italy; Latvia; Lithuania; Macedonia, the former Yugoslav Republic of; Moldova; Montenegro; Poland; Romania; Russian Federation; Serbia; Slovakia; Slovenia; Spain; Switzerland; Turkey; Turkmenistan; Ukraine

Population [top]

Population:In northern parts of its range it is scarce and may be declining, whereas in southern parts of its range it is sufficiently abundant to be considered an agricultural pest in years of high population density. In central Europe, typical population densities may be c.5 individuals per hectare, although densities of 20-22 individuals per hectare have been recorded (Kryštufek 1999).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is typically found in mature deciduous and mixed woodland, where it frequents the canopy, although it also occurs in maquis and shrubland on rocky areas along the Mediterranean coast. Man-made habitats such as gardens and orchards are sometimes used, and the species often enters buildings (Macdonald and Barrett 1993, Kryštufek 1999).
Generation Length (years):3

Use and Trade [top]

Use and Trade: Hunted for human use.

Threats [top]

Major Threat(s): In parts of its range, including Slovenia, Croatia, and Italy, there is a tradition of hunting this species. In the past, it was a source of meat, fat, and skins for subsistence and trade, but today it is hunted recreationally (Kryštufek 1999). The species is protected in Italy, but is sometimes illegally hunted (G. Amori pers. comm. 2006). In northeastern Europe, cutting of oak forests is a threat (Juškaitis 2003).

Conservation Actions [top]

Conservation Actions: It is listed on Appenix III of the Bern Convention. It occurs in protected areas throught its range.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
