Fallow deer Dama dama

Taxonomy: Class: Mammalia; Order: Artiodactyla; Family: Cervidae

Description

Fallow deer © Peter Thompson

The fallow deer went extinct in Britain during the last Ice Age, and was re-established by the Normans for hunting in the 11th century. Typically its coat is fawn with white spotting, but white varieties also occur, as do black ones. The male has palmate antlers cast in April-June. The fallow deer prefers mature broad-leaved or mixed woodlands. Bucks may be shot from 1 August to 30 April, does from 1 November to 31 March.

Recent trends from the National Gamebag Census

United Kingdom

Index of bag density from 1976 to 2009 (see statistical methods and interpretational considerations).
Error bars represent 95% confidence intervals.

Too few sites provided records to evaluate trends before 1976. After a brief initial increase after 1976, the UK bag index has remained approximately stable between 1982 and 2009. The period of increase corresponded to a period of range expansion that slowed after the 1990s (see maps).

Change in fallow deer bags over time, with 95% confidence limits (see statistical methods):

Country	Sites	Start year	End year	Change (%) 1961-2009	Change (%) 1984-2009	Change (%) 1995-2009
United Kingdom	150	1976	2009	370 -21 to 1051	84 -7 to 338	30 -23 to 141

* significant at P < 0.05

England

Index of bag density from 1976 to 2009 (see statistical methods and interpretational considerations).
Error bars represent 95% confidence intervals.

Too few sites provided records to evaluate trends before 1976. The bag index for England has remained approximately stable between 1976 and 2009., with perhaps a brief initial increase. Throughout this period there was an expansion in range (see maps).

Change in fallow deer bags over time, with 95% confidence limits (see statistical methods):

Country	Sites	Start year	End year	Change (%) 1961-2009	Change (%) 1984-2009	Change (%) 1995-2009
England	127	1976	2009	107 -46 to 507	47 -14 to 303	21 -31 to 148

* significant at P < 0.05

Scotland

Index of bag density from 1976 to 2009 (see statistical methods and interpretational considerations).
Error bars represent 95% confidence intervals.

Just seven sites reported fallow deer in Scotland between 1961 and 1975. There has been a significant increase in the bag index from 1976 onwards following range expansion and increasing abundance (see maps).

Comparison with BBS mammal data

Since 1995, data on fallow deer abundance have been collected under the Breeding Bird Survey (BBS) organised by the British Trust for Ornithology. Below, the UK trend from the NGC is compared to the one from the BBS (from 1995 onwards).

NGC index of bag density (blue) and BBS index of abundance (red), from 1995 to 2009.
Error bars represent 95% confidence intervals.

The BBS records are limited to England and show no significant change. For all years, the BBS confidence intervals are completely or almost completely within the NGC confidence intervals, indicating good agreement between the two index series.

Long-term trend from the National Gamebag Census

There are too few bag records of fallow deer to produce a trend starting before 1976.
