1. Deer Human-Wildlife Conflict

2. • Situated in Sevenoaks, Kent. (TQ545538)
• Kent's last remaining medieval deer park
• 1, 000 acre deer park owned the National
• Part of Kent Downs Area of Outstanding Natural Beauty
• Site of Special Scientific Interest
• Site includes habitats such as parkland, woodland, acidic
grassland, wildlife ponds
• Supports rare beetle such as Cerylon fagi (fig.1.) and rare
fungi such as Geastrum fornicatum (earth star) (fig.2.)
• Originally the Archbishop Thomas Bouchier house in
1456 (former hunting ground of Henry the VIII); was then
passed down to the Sackville family in 1603

3. • Fallow deer (Dama dama) were originally kept
in the park for hunting by the Archbishop
• Current population of fallow deer is between
350-400; decedents of original 15th century herd
• Japanese Sika deer (Cervus nippon) where
introduced in the 1890’s for ornamental
purposes
• Current deer manager: Thomas Marshall
• Current deer keeper: Dom Andrews

4. • Public feeding deer and dogs let lose harassing deer
• Lack of acknowledgement of the threats dogs pose to deer; with attacks
leading to slow painful deaths and abortion in pregnant ewes
• Picnics and food availability from members of the public; leading to
conditioning
• Deer not feed can become aggressive posing a risk to people;
particularly young children
• Deer’s crossing roads with potential for collision or blocking vehicle
access
• Deer are £1,000 to purchase, plus additional husbandry costs

5. • Increasing deer vehicle accidents (DVA’S), and the associated economic and animal welfare costs,
has led to further research including environmental and ecological factors leading to such
incidents (Steiner, et al., 2014).
• GPS monitoring has been carried out to identify deer movements and home ranges and risks
zones in relation to seasons, habitat characteristics, deer behaviour, speed limit and road design
(Meisingset, et al., 2014).
• GIS has been utilised to map sites of DVA’s in the City of Edmonton, Alberta, to identify areas of
high collision incidents; the study revealed that collisions where more likely in areas of dense
vegetation and less likely in areas with a 40m buffer of absent vegetation (Found and Boyce, 2011)
• Also been applied in Spain for investigation of Roe Deer (Caprelous caprelous) and Wild Boar
(Sus scrofa) collisions (Rodríguez-Morales, 2013).
• Mitigation methods include; warning signs on roads, speed limits, fencing, reflectors, chemical
repellents, and one way gates (Found and Boyce, 2011; Meisingset, et al, 2014).
• Animal welfare and behaviour considerations are required (Putmam, 1997; Goddard, et al., 2001)

(Found and Boyce, 2011) (Rodríguez-Morales, 2013).

7. • Tracing features and digitisation of a map can identify key conflict areas, e.g. roads and car park
• The Buffer tool can be used to establish a uniform area in which mitigation fencing can be placed (Ormsby,
2011)
• Previous studies have stated that a vegetation free buffer of >40m reduces deer-vehicle collisions (Found and
Boyce, 2011).
• However, it is recommended that fencing does not exceed beyond high risk areas as fencing can disrupt
habitat connectivity; a buffer of 20m could therefore be selected for fencing (Ascensãoa, et a., 2013; Goddard,
et al., 2011; Putmam, 1997)
• Fencing can lead to undesired behaviour (e.g. pacing) and can be costly (Goddard, et al., 2011; Putmam, 1997)
• Partial fencing of roads is suggested to be the most effective mitigation (Ascensãoa, et al, 2013)
Advantages of the buffer tool
• Area of focus identified in which fencing can be put into place to reduce collisions (Ormsby, 2011)
• Cost and time effective (Longley, et al, 2011)
Disadvantages of the buffer tool
• Human-wildlife issues, deer behaviour and welfare could be over looked outside the buffer (Goddard, et al.,
2001)
• Establishment of fencing can be costly and time consuming (Ascensãoa, et al., 2013; Goddard, et al., 2001;
Putman, 1997)

9. • Deer-vehicle collisions are one of many human-wildlife
conflict issues that can be investigated with GIS
(Kempster, 2014; Word Press, 2013).
• GIS can be used to put appropriate mitigation methods
in place and monitor human-wildlife conflict issues;
including conflict with domestic dogs and public
feeding deer (Found and Boyce, 2014; Ormsby, 2001).
• The buffer tool can be used to create a uniform area in
which deer fencing can be established (Ormsby, 2001)
• However Knole park must be considered as a whole
outside the buffer zone as well as deer welfare and
habitat connectivity; this can be investigated using GIS
(Ascensãoa, et al, 2013; Goddard, et al., 2011).
