The nineteenth century saw the introduction of many ‘exotic’ or non native species.  Some of these introductions have proved to be invasive, for example the Himalayan balsam.  Invasions have also included animals. For example, muntjac, parakeets and grey squirrels.  More recently, there have been many sightings of wallabies. Their presence is thought to be due to escapees from wildlife parks, zoos and possibly private collections. It has been suggested that some were released during the WW2 as people were unable to look after them.  On the Isle of Man, there is a thriving population of red necked wallabies, which dates back to the 1960’s.  A recent survey (2023 & 2024) using thermal imaging and drones estimates the population to be around one thousand animals, possibly more.  The grassy and woodland habitats are not dissimilar to those in Tasmania, though the climate in the Isle of Man is somewhat cooler and wetter.  Here, there are no predators and they seem to have adapted well to the somewhat cooler conditions. They feed on heather, bracken, bilberries and grasses.  The local wildlife trust is concerned that the animals may be having a detrimental effect not only on the native vegetation but also the local fauna - such as ground nesting birds.  On the plus side, there are those who think their presence helps to support the local tourism industry. Beyond the Isle of Man, there have been many sightings of wallabies across the U.K, ranging from Cornwall to Scotland.  Sightings are more common in the South.  In some areas sightings of wallabies are no longer reported as the animals are ‘common place’. The Chilterns being a possible hot spot for sightings.  However, at present it seems that there is little evidence for self sustaining populations though this might change as our climate becomes milder.  There was a small population in the Peak District but it has since died out, possibly due to a harsh winter in 2010.  This population arose from the introduction of five wallabies by a local landowner, Henry Brocklehurst,  the  wallabies formed part of his private zoo at Swythamley.

  There are now more deer in the UK than there have been for 1,000 years.  Probably between 650,000 and 2,000,000, of which about half live in Scotland. Dormice like sleeping and can sleep for up to 7 months a year. UK woodlands are home to half the world’s flowering bluebells. There are 15,000 species of fungi, on land, in water and even on plants and animals. Swallows migrate annually to Southern Africa travelling 6,000 miles twice a year. Grey squirrels have become a problem because they were released deliberately, in 1876. Half the deer species in the UK were escapees - three of our six deer species, being Muntjac, Sika, Chinese Water Deer. Conifers have been around so long that they were dinosaur food - about 300 million years. The oldest British trees predate Christianity, Islam and Buddhism. One of the oldest is the Fortingall Yew in Scotland, estimated to be as much as 3,000 years old. Not all conifers have cones - the Juniper, for example, has fruits that are tiny, round, fleshy and berry-like.  

Deer are eating out the bottom of our woodlands and wildlife is suffering.  Although the size of the national deer population is not known for sure it is probably at its highest for a thousand years. There may be as many as two million deer in the UK’s countryside. There are several types, such as the two native species, being the Red deer (Cervus elaphus) and the Roe deer (Capreolus capreolus) - which is the most populous of the larger deer being, perhaps, 500,000 animals. Then there are the ones the Normans introduced, the Fallow deer (Dama dama) with a population of at least 150,000. On top of that there are three species of deer which have been introduced from the Far East including the Sika deer (Cervus nippon).  The other two from China are very different - there are relatively small numbers of the Chinese Water deer (Hydropotes inermis), whereas there are probably hundreds of thousands of the small and mostly nocturnal Muntjac (Muntiacus reevesi). They are all hungry and they all love woodlands. Most people believe the deer population needs to be controlled, or even reduced in number, but the range of species makes that harder to do. If you reduce the population of one type of deer the others will expand their numbers. Culling, or shooting, is certainly helping but stalkers are usually only interested in the larger species with enough meat to make it worthwhile and this leaves the muntjac space to thrive. Here is a film we made of a Scottish deer stalker explaining her job and how her stalking helps with environmental management: [embed]https://www.youtube.com/watch?v=ISh2sN-Ljy8&ab_channel=WoodlandsTV[/embed] Megan: “99% of stalking is looking through the binoculars.” Other ways of controlling the deer population are fencing them out but that is expensive and unlikely to work in the large open areas of the British countryside such as the moors and the uplands. Another potential method of control is introducing predators such as lynx or other larger hunting species. This meets some resistance from the public and the unintended consequences are that the predators might well go after different species altogether and occasionally humans. Most work is going on with contraceptive solutions so that the birth rate is reduced and less killing or culling is needed. This is also being researched for controlling populations of wild boars and grey squirrels to keep their numbers in check. It means getting the drugs to the target species and usually to the females which is often done through their foodstuffs, using food hoppers which are designed to be only accessible to that species. Other approaches include sterilization through injections and the Deer Initiative partnership has done a lot of work on examining different methods of biological control of deer numbers: https://www.thedeerinitiative.co.uk/pdf/contraception-and-wild-deer-control.pdf It’s not easy.  Even if one of these methods works, it will require an enormous effort to cut deer populations particularly of the smaller and more evasive species such as the muntjac. What do you think should be done? Meanwhile , deer are dangerous to motor cars.  The British Deer society estimates that annually there are between 40,000 and 70,000 accidents involving deer and this leads to about 700 human injuries, and far more deer fatalities!. So, in short, an overpopulation of deer is a large and growing problem: they damage the flora in woodlands, they eat young saplings, they compete with other mammals for space, they eat farmers’ crops, they carry ticks and they cause road accidents. The challenge of controlling the deer population is very real.

A few years ago I started deer stalking with my wife, Roxanna, for three reasons:- we wanted to do something useful to help control the burgeoning deer population, we like eating venison and we wanted to do something active in the country side. In the absence of the natural apex predators, such as Lynx, wolf and bear, deer are now threatening to become a serious nuisance in some parts of the country.   Deer have co-evolved with predators which have now been eliminated, so the deer are at risk of 'eating the bottom out' of British Woodlands; preventing the natural regeneration of trees for future generations. This creates a need for culling of selected deer but it needs to be done in a way that is safe and humane Read more...

Muntjac deer ("Muntiacus reeves") are small but they reproduce quickly.  They are fast becoming a major threat to wildlife.  Because they tend not to eat agricultural crops, they are not controlled by farmers so they are in danger of 'eating out' the floors of English deciduous woodlands - which are so important to biodiversity.  These deer were originally introduced into this country by mistake after they escaped from Woburn Safari park in about 1925, and since then they have spread through most of England but are concentrated south of the M62 motorway (Hull to Manchester).

The wholesale destruction of ancient woodland through farming and forestry has diminished but new roads,  bypasses and the installation of infra-structure & services (such as utilities & power lines) can still be a problem.  In recent times, new or different threats to ancient woodlands have emerged to upset the balance of woodland ecosystems. In the 1960’s and early 70’s concern focussed on the effects of air and acid rain pollution .  Such pollution was characterised by the deposition of sulphur dioxide and its derivatives (sulphuric & sulphurous acid), plus various nitrogen oxides.

Nightingales are migratory birds and fly into the U.K. in the Spring, having spent the winter in Africa. The nightingale is particularly well known for its song; (a wma file of which can be found here).  However, not everybody in the UK is likely to hear them singing.  It is not found in Scotland or Wales, and in other places its numbers have fallen quite dramatically.  It is now mainly found in the South-East, especially Kent, Sussex, Suffolk and Norfolk. A sighting is unlikely; nightingales are shy, drab brown birds who seek the dense vegetation described below. Read more...

Woodland owner and occasional deer stalker, James, gives us his personal views and advice on deer management gained from his own experience. Like many woodland owners we have deer in our woodland.  The deer population in the UK is increasing rapidly and woodland owners need to consider a number of issues when dealing with deer stalkers or those offering deer management services. Building a relationship with a good, reliable deer stalker can be very beneficial.  Besides controlling the deer population, he can keep an eye on things when you are not around, and may well be able to help out with odd jobs and other pest control.  However, there are a lot more stalkers – most of them amateur or recreational - than stalking opportunities, and it pays to take a little bit of care over whom you choose.  Read more...
