European fallow deer


The European fallow deer, also known as the common fallow deer or simply fallow deer, is a species of deer native to Eurasia. It is one of two living species of fallow deer alongside the Persian fallow deer. It is historically native to Turkey and possibly the Italian Peninsula, Balkan Peninsula, and the island of Rhodes near Anatolia. During the Pleistocene it inhabited much of Europe, and has been reintroduced to its prehistoric distribution by humans. It has also been introduced to other regions in the world.

Taxonomy

Some taxonomists include the rarer Persian fallow deer as a subspecies, with both species being grouped together as the fallow deer, while others treat it as a different species. The white-tailed deer was once classified as Dama virginiana and the mule deer or black-tailed deer as Dama hemionus; they were given a separate genus in the 19th century.

Description

The male fallow deer is known as a buck, the female is a doe, and the young a fawn. Adult bucks are long, in shoulder height, and typically in weight; does are long, in shoulder height, and in weight. The largest bucks may measure long and weigh. Fawns are born in spring around and weigh around. Their lifespan is around 12–16 years.
Much variation occurs in the coat colour of the species, with four main variants: common, menil, melanistic, and leucistic – a genuine colour variety, not albinistic. White is the lightest coloured, almost white; common and menil are darker, and melanistic is very dark, sometimes even black.
  • Common: Chestnut coat with white mottles, it is most pronounced in summer with a much darker, unspotted coat in the winter. The light-coloured area around the tail is edged with black. The tail is light with a black stripe.
  • Menil: Spots are more distinct than common in summer and no black is seen around the rump patch or on the tail. In winter, spots are still clear on a darker brown coat.
  • Melanistic : All year the coat is black, shading to greyish-brown. No light-coloured tail patch or spots are seen.
  • Leucistic : Fawns are cream-coloured; adults become pure white, especially in winter. Dark eyes and nose are seen. The coat has no spots.
Most herds consist of the common coat variation, yet animals of the menil coat variation are not rare. The melanistic coat variation is generally rarer, and the white coat variation is very much rarer still, although wild New Zealand herds often have a high melanistic percentage.
Only bucks have antlers, which are broad and shovel-shaped from three years. In the first two years the antler is a single spike. Their preferred habitat is mixed woodland and open grassland. During the rut, bucks spread out and females move between them; at that time of year fallow deer are relatively ungrouped compared with the rest of the year, when they try to stay together in groups of up to 150.
Agile and fast in case of danger, fallow deer can run at a maximum speed of over short distances. Being naturally less muscular than other cervids such as the roe deer, they are not as fast. Fallow deer can also jump up to high and up to in length.
The diet of the European fallow deer has been described as highly flexible, and able to adapt to local conditions. A 1977 study of European fallow deer in the New Forest of Britain found that European fallow deer were selective mixed feeders, feeding primarily on grass during the spring and summer, while primarily feeding on acorns and other mast during autumn until late December, with winter foods including grass as well as shrubs like brambles, bilberry, heather, holly, as well as ivy and coniferous material.

Distribution

During the Last Interglacial around 130-115,000 years ago and prior, European fallow deer were widely distributed over Europe, occurring as far north as the British Isles. During the Last Glacial Period the range of the species collapsed due to unfavourable climate conditions, surviving in refugia in Anatolia and probably the Balkans and possibly elsewhere, though the fossil record of their distribution during this time is sparse.

Turkey

Turkey is the only country known to have definitively natural populations of European fallow deer since the Last Glacial Maximum, but populations there have since become endangered and almost fully extirpated. European fallow deer in Anatolia underwent a major population decline due to the spread of agriculture and hunting, and populations in the Marmara and Aegean regions went extinct by the turn of the 20th century. Other wild populations of Turkish fallow deer survived for longer on islands at Ayvalık Islands Nature Park, Gökova, and Adaköy near Marmaris, but also appear to have died out in recent years. Currently, the only extant wild population of the species known to be undoubtedly natural lives in Düzlerçami Game Reserve in the Mount Güllük-Termessos National Park in southern Turkey, although the area has been largely fenced since, making the population only semi-wild. This population is very few in number and is genetically distinct from other European fallow deer.
A 2024 study suggests that the Turkish populations of fallow deer are ancestral to most fallow deer found throughout Europe as well as introduced populations worldwide. The translocations of fallow deer out of Turkey were facilitated by Roman-era trade networks. The only other refugium found was one in the Balkans, whose surviving descendants are significantly fewer in number.

Native but originally extinct

Southern Balkans

On mainland Greece and some Greek islands, such as Corfu, Kythira, and Thasos, that were connected to mainland due to lower sea level or proximity to land, fallow deer were present during the last ice age. A belief arose that the species was almost extinct in Greece, returning during the Neolithic. Contrary to that, remains indicate that reduced numbers survived in several parts of the country like in Thessaly, Peloponnese and Central Greece, increasing and becoming common during mid Neolithic, but mostly east of Pindus mountain range and especially in Macedonia and Thrace. During the Neolithic period and the Bronze Age, the species survived on the islands of Corfu and Thasos, appeared on Euboea, and began to be introduced by man to other islands, including Crete, some of the Cyclades, Rhodes, Chios, Lesbos, Samos and Sporades.
Early-historic-period remains have been found in eastern Greece and on the islands of Thasos, Chios, Rhodes and Crete. A few surviving individuals were observed on Samos in 1700, while the species became extinct on Lesbos late in the Ottoman period. On the Greek mainland, wild fallow deer survived until the 16th century in northeastern Chalkidiki, until the 19th century in the forests of Mount Olympus, Vermio Mountains, Arakynthos, Evrytania and Boeotia and until the 1910s in Thesprotia. The last individuals were hunted in Acarnania during the 1930s.
In Bulgaria, the autochthonous population of fallow deer is believed to have declined and disappeared after the 9th or 10th centuries, and the species was reintroduced there much more recently. The species remained in European Turkey into the 19th century. A male fallow deer was captured in Thrace in 1977 and translocated to Düzlerçamı, suggesting that a small population existed there at that time. In Albania, the fallow deer seemed to be plentiful during the first half of the 19th century.
A 2024 genetic study suggests that the Balkans served as one of two refugia for fallow deer during the glacial periods, alongside Anatolia. Members of this population were also translocated around Europe during the Iron Age and Roman Empire, but have largely been replaced by Turkish-origin fallow deer aside from parts of southern Europe. The Balkan fallow deer are thought to represent the ancestors of modern Iberian, Italian, and Rhodes fallow deer, with the Rhodes population dating back to Neolithic translocations.

Possible native populations

Aside from Turkey, other areas of Europe that could have potentially served as refuges for the species during the last ice age include parts of the eastern Mediterranean, including most of the Italian Peninsula, parts of the Balkans, and the Greek island of Rhodes, all of which still host populations of this species. However, palaeontological and archaeozoological evidence of the species' diffusion into these areas during the ice age is very fragmentary, thus whether the present populations in these areas are truly native descendants of relict populations or were introduced by humans is unknown. Presently, the IUCN Red List's range map lists European fallow deer as being native to Italy, Turkey, Rhodes, and most of the Balkans, as having a population of uncertain origin in central Bosnia and Herzegovina, and being introduced to the rest of Europe. In the text, though, all the eastern Mediterranean populations aside from Turkey are listed as having an uncertain origin. A 2024 study suggests that Italian and Iberian populations descend from a now-extinct Balkan population that was translocated early on.

Rhodes, Greece

The Rhodian population of European fallow deer is smaller on average than those of central and northern Europe, though they are similarly coloured. European fallow deer are said to have been introduced to Rhodes in Neolithic times; although fossils of the species on Rhodes do indeed go back to Neolithic times, no major evidence has been found of domestication, so they could be considered native. In 2005, the Rhodian fallow deer was found to be genetically distinct from all other populations and to be of urgent conservation concern. At the entrance to the harbour of Rhodes city, statues of a fallow deer buck and doe now grace the location where the Colossus of Rhodes once stood.

Introduced

Outside of Europe, this species has been introduced to Algeria, Antigua and Barbuda, Argentina, Australia, Canada, Cape Verde, Chile, the Comoros, Cyprus, the Falkland Islands, Fernando Pó, Israel, Lebanon, Madagascar, Mauritius, Mayotte, Morocco, New Zealand, Peru, Réunion, São Tomé, the Seychelles, South Africa, Tunisia, and the United States.
