IS SCOTLAND HAVING A DEER PROBLEM?
Yes — but it is more accurate to say that Scotland has a deer-management challenge rather than simply a “deer problem.”
Deer are an important part of Scotland’s wildlife, culture and rural economy. However, NatureScot states that deer numbers are increasing in parts of Scotland and that high densities are preventing woodland regeneration, damaging crops and existing woodland, and overgrazing and trampling peatlands.
Because Scotland’s wild deer have no natural predators capable of regulating populations, active management is necessary. NatureScot currently estimates that the national cull may need to increase by around 25%, or approximately 50,000 deer per year, for several years to meet biodiversity objectives.
Why deer management matters: it keeps deer populations in balance with their habitat, protects woodland and agriculture, supports peatland and biodiversity restoration, reduces deer–vehicle collision risks, maintains deer health and welfare, and provides sustainable wild venison.
A useful way of putting it is:
The problem is not deer themselves — it is having more deer than the land can sustainably support. Good deer management aims to achieve healthy deer populations, healthy habitats and a sustainable balance between the two.
SCOTLANDS DEER
Deer are an iconic part of Scotland’s landscapes, with four main species present: red, roe, fallow, and sika. Red deer, the largest, dominate upland moors and glens, while roe deer thrive in lowland woods and farmland. Fallow and sika, introduced species, occur in scattered or expanding populations. Deer play important ecological and cultural roles, but high numbers can damage young trees, crops, and biodiversity, and increase road collisions. Careful, evidence-led management—through habitat design, fencing, and regulated culling—balances conservation, forestry, farming, and rural economies, while ensuring the long-term health of Scotland’s wild deer populations.
In Perthshire we have three of the four species present - roe, red and fallow.
Scottish Roe Deer (Capreolus capreolus)
Status: Native and widespread in Scotland.
Size: 60–75 cm at shoulder; 15–30 kg.
Lifespan: 3–7 years (rarely up to 10).
Diet: Buds, herbs, bramble, heather, young shoots.
Activity: Mostly dawn/dusk, often solitary.
Antlers: Bucks only; shed in autumn, regrow over winter.
Identification: Reddish-brown in summer, grey in winter; white rump patch; short face and dark eyes; small upright antlers.
Breeding: Rut July–Aug; fawns born May–June after delayed implantation.
Impacts: High numbers can damage young trees, crops and increase vehicle collisions.
Signs: Small neat tracks, pellet droppings, frayed saplings, rut scrapes.
Open season in Scotland:
Bucks: year-round
Does: from 21st October to 31st March.
Scottish Red Deer (Cervus elaphus)
Status: Native to Scotland, common in the Highlands, expanding into the lowlands.
Size: Stags 100–190 kg, hinds 70–120 kg; shoulder 90–120 cm.
Lifespan: Typically 10–14 years (rarely up to 20).
Diet: Grasses, sedges, heather, tree shoots, farm crops.
Activity: Graze in herds, often on open hill or moorland; also woodland edge.
Antlers: Stags only; large branching antlers, cast in spring, regrow in velvet, cleaned by late summer.
Identification: Large reddish-brown body (greyer in winter); pale rump patch, short tail; stags with mane and prominent antlers.
Breeding: Rut September–October; roaring stags defend harems; calves born May–June.
Impacts: Heavy grazing pressures habitats, limits woodland regeneration, damages crops, and increases road collision risk.
Signs: Large slots (7–9 cm), groups of pellets, bark stripping, wallows, roaring in rut.
Open season in Scotland:
Stags: year-round
Hinds: from 21st October to 15th February
Fallow Deer (Dama dama)
Status: Introduced species; established in scattered areas of Scotland (not native).
Size: Bucks 60–100 kg, does 35–55 kg; shoulder 75–95 cm.
Lifespan: 8–12 years in the wild (occasionally longer).
Diet: Mixed feeder—grasses, herbs, crops, young woodland browse.
Activity: Herd-forming; active at dawn/dusk, often in parkland or mixed farmland/woodland.
Antlers: Bucks only; broad, flattened (palmate) antlers; cast in April–May, regrown by late summer.
Identification: Variable coat—commonest is chestnut with white spots in summer, grey-brown in winter; distinct white rump with black edging and long tail—slender build, smaller than red, larger than roe.
Breeding: Rut in October; bucks grunt and defend rutting stands; fawns are born in June.
Impacts: Can heavily graze crops and woodland; may hybridise with other populations; road accidents are a concern.
Signs: Medium-sized slots (~5–6 cm); pellet groups; tree fraying and buck scrapes in rut.
Open season in Scotland:
Bucks: year-round
Does: from 21st October to 15th of February
Scottish Sika Deer (Cervus nippon)
Status: Introduced from East Asia; established in parts of Scotland. Can hybridise with red deer.
Size: Stags 40–70 kg; hinds 30–45 kg.
Diet: Grasses, heather, tree shoots, bark and crops.
Activity: Secretive woodland deer, most active around dawn, dusk and at night.
Antlers: Stags only; usually smaller and simpler than red deer antlers.
Identification: Reddish-brown with white spots in summer; dark grey-brown in winter. Distinct white rump patch edged in black.
Breeding: Rut September–November; stags make a distinctive high-pitched whistle. Usually one calf born May–June.
Impacts: Browsing, bark stripping and forestry damage. Hybridisation with red deer is an important conservation concern.
Signs: Small slots, pellet groups, bark damage, wallows and rutting whistles.
Open season in Scotland:
Stags: Year-round.
Hinds: 21 October–15 February.
