The Fallow deer is a medium-sized cervid that has been widely translocated within Europe by early civilisations. Originating from Turkey and Iran, the Fallow deer was introduced to Britain by the Normans during the 11th century and is still kept widely in deer parks and farms in Britain. Those in our countryside today are descendants of mediaeval introductions or escaped from parks that fell into disrepair during the World Wars. Despite being an introduced species, it is not considered invasive, although they can negatively impact forestry if populations aren't managed.

That which follows is a brief summary of Fallow deer natural history. The detailed article for this species is in preparation. Certain aspects of the natural history common to all deer (e.g. antler growth and formation, collisions with vehicles, chronic wasting disease) have been split from the individual overviews and placed into their own QA – this is partly to avoid repetition but also to allow more detailed coverage of the topics. A summary of the more general aspects of the biology, ecology and behaviour of Britain’s deer species can be found in the Deer Overview.

The Fallow deer at a glance

Two subspecies, Dama dama dama and the Mesopotamian fallow Dama dama mesopotamica, although some consider this a separate species (i.e. Dama mesopotamica). Non-native species that appears to have been introduced to Britain by Romans around AD 43, dying out shortly after Roman withdrawal; current population probably stems from introduction in late 11th century by Norman invaders.

Size: Adults 1.3 to 1.7 m (4 – 5.5 ft) long; buck (male) stands 85 to 110 cm (nearly 3 to 3.5 ft) at shoulder. Weight 35 to 130 kg (77 – 287 lbs). Females (does) slightly smaller than bucks.

Colour: Hugely variable. Red-brown coat with white spots in summer and grey-brown coat in winter, with less distinct spots. White rumps with black borders; large palmate antlers on males. Four recognised colour phases: Common (rust with black dorsal line), Menil (tan with brown dorsal line), Black (or melanistic) and White (albino and non-albino).

Distribution: Probably most widely distributed deer in world thanks for introductions by humans. Common throughout UK, where it’s naturalised, and much of Central Europe; absent from Iceland and most of Scandinavia. Introduced to America and New Zealand. Bulk of British population in southern England and eastern Wales; patchy distribution in northern England, western Wales, Scotland and Ireland. Population estimated to be growing at ca. 2% per year; 2008 data numbers put at 150,000 to 250,000.

Longevity: In wild reach 8 to 10 yrs, exceptional ages of 16 yrs known; oldest captive specimen was 20 yrs old.

Sexing: Males have antlers for much of year (shed in spring), laryngeal prominence (Adam’s apple) and penile sheath.

Antler Cycle: Antlers cast late March to early June (peak mid-April to mid-May); velvet shed August/September.

Activity: Active throughout day and night, with peak at dawn and dusk. Open spaces used ony at night by disturbed populations. Seasonally variable activity patterns; alternate between periods of feeding and ruminating.

Habitat: Areas of mixed or deciduous woodland and grassy open spaces with shrubby undergrowth for shelter and feeding. Can be found in open conifer stands.

Territory: Non-territorial with overlapping ranges. Prepare for rut late August and early September; maintain rutting stands to which does are attracted (‘lekking’), or may ‘herd’ females more akin to Red deer, depending on location/habitat – peak rut in October. Home range varies with season and habitat: e.g. in New Forest (UK) males = ~50 to 250 ha (123 – 618 ac.), females = ~50 to 90 ha (up to 222 ac.).

Diet: Primarily grasses and bramble; bark and shrubs may be taken during the autumn and winter.

Reproduction: Rut during October (peak around 20th) and a single calf is born after 230 day (~33 wk / 8 mo.) gestation (typically during May/June); twins rare (<1% births). Calf suckled for 6 to 9 months; stays with doe for first year.

Behaviour and Sociality: Generally speaking a gregarious species that live in groups of, at times, a hundred individuals. Social structure in does, with single dominant female, although social structure highly variable with environment. Mixed sex groups may form at good feeding sites.

Threats: Hunted for sport in parts of their range, although stag hunting with hounds is now illegal in the UK. Roads can pose threat to deer; people often killed or seriously injured upon collision with deer – Fallow more frequently hit by cars than other deer species. Sometimes come into conflict with forestry or private land owners because of the damage they can do to trees (esp. ancient woodland), crops and flowers.
