The history of wild deer on the Isle of Wight reflects the neighbouring areas on the mainland coasts of Hampshire & Dorset,with deer populations establishing after the last Ice Age and fluctuating ever since.
Both wild and captive deer probably disappeared altogether from the island in the middle of the 19th century, around the time that the Worsley Estate was sold and carted deer hunting ceased, and only began to be seen again in the wild in the mid 1970’s
Wild deer remain comparatively scarce on the Isle of Wight, Reds and Muntjacs are probably the most common species with the odd Fallow and Roe occasionally being seen. Deer are sometimes seen swimming across Southampton Water and the Solent to the island.
A few myths about our resident wild Isle of Wight deer:-
1. There are no wild deer on the Isle of Wight
Many people will have heard that the Isle of Wight has a “deer free status”, the Forestry Commission have recently clarified what they mean by this:- ” This is of course a relative term which compares the minimal deer numbers on the Isle of Wight with significant populations on the mainland”. Obviously their use of the term “deer free” has been very misleading.
2. Deer are an introduced species like Grey Squirrels and American Mink
There are 6 species of wild deer in the UK, evidence of 5 of which have all been seen on the island in recent years. Red and Roe are native* deer that recolonised England including the land that was to become the Isle of Wight after the last Ice Age, whilst Muntjac, Fallow and Sika are introduced species.
3. They are all deer farm escapes and there are no naturally occurring deer on the island
Red deer and Muntjac have been breeding in the wild for some years now and deer are known to swim across the Solent*. The last commercial deer farm on the island closed around the year 2000. Roe and Muntjac are not kept in deer farms at all. A FOI request revealed that the IWC had no evidence to support their claim that there are no naturally occurring deer on the island.
No public authority has been able to produce firm evidence of any escaped farmed deer when challenged under FOI/EIR regulations
4. The vegetation on Isle of Wight is more lush and varied compared to the mainland and biodiversity is greater due to the relative absence of deer
The mild climate and geology of the Isle of Wight are the prime reasons for our vegetation being different from many areas of the mainland and was recorded as such hundreds of years ago when wild deer were more abundant on the island. Both historical and archaeological records show that our rich woodlands evolved in the presence of wild deer.
Dorset claims greater floral diversity than the island whilst Hampshire claims to have the most varied biodiversity in the country, both of these counties have strong deer populations.
5. Populations of rare mammals such as Woodland Bats, Red squirrels and Dormice are threatened by the presence of deer
The JNCC report on the status of our wild mammals makes no such claim, in fact Bats in particular benefit from deer grazing woodland pastures and rides which enables the Butterflies and Moths that they feed on to thrive. Some Bats also feed on the coprophagous insects found in deer dung.
6. Nightingales are only found when deer are absent
Nightingales breed mostly south of the Severn-Wash line and east from Dorset to Kent. The highest densities are found in the south east: Essex, Suffolk, Norfolk, Kent and Sussex, all these counties have significant populations of wild deer.
7.Woodland Biodiversity is harmed by deer
It has been established by scientific research conducted in North America, Great Britain and Europe that woodland biodiversity is at its greatest when deer are present at low density and decreases when deer are either totally absent or at a very high density.
8. In the UK deer spread diseases such as bluetongue
Bluetongue is a non-contagious disease of ruminants found in tropical and subtropical areas that rarely occurs elsewhere, it is carried and spread by the Culicoides imicola midge that cannot overwinter in our climate. No deer within the UK have ever been found to be infected with this virus.
9. Deer cause Lyme Disease
Lyme disease is an infection caused by a group of bacteria called Borrelia burgdorferi which are transmitted to humans following a bite from an infected Sheep tick Ixodes ricinus. Despite its name the Sheep tick will feed from a wide variety of mammals and birds. Bites from other ticks are possible, including the Hedgehog tick , Ixodes hexagonus, and the Fox and Badger tick, Ixodes canisuga. These ticks become infected during their larval and nymphal phases by feeding on the small mammals and birds which harbour the Lyme bacterium. Later in their development the infected nymphs and adults transfer the Lyme bacteria to the animals and people on which they feed. On the Isle of Wight there are over 30,000 Sheep and abundant small mammals and wild birds that can perform the role of a host for the Ixodid ticks and the diseases that they carry. Deer do not infect the ticks but it is the ticks that infect the deer!
The important thing is to be aware of the dangers caused by a tick bite and to seek prompt medical help if bitten. Take special care when walking through long damp grass etc. as this is where ticks are found after falling off one host to await the next. More useful information may be found on the Lyme Disease Action Website
