We purchased Knox Wood in August 2023, part of Boltonmuir Wood, an old woodland site on fairly boggy ground in East Lothian. Our five acres are split 50% almost pure birch (Silver and Downy) regenerating [about 20 years old] and 50% mature Scots Pine that is well thinned over mixed natural regeneration.  All of the site has previously been used for commercial forestry so there is plenty of natural regeneration from Sitka Spruce, Douglas Fir, Western Hemlock, Silver Fir and Larch. Some oak, rowan, hawthorn and beech regeneration is also present. Roe deer use the site but are not having much impact on the trees, just ticks to be aware of.   Plenty of mosses, ferns and bracken that indicate acidic soil conditions. Our plan is to improve the site for biodiversity and use some birch for green wood working.  So far we have been taking out non-native conifer regen, leaving a few that are suitable for bird nesting and to provide a bit of evergreen shelter. A few Rhododendrons to eliminate as well, easy enough using the lever and mulch technique. We will create some standing deadwood and add to the fairly good level of deadwood from previous birch thinning that is now well rotten.  We will add a few native species, such as Aspen and maybe more Willows for weaving.   Also hoping to grow some edible fungi on site, there are wild mushrooms and I am sure plenty of people already roam around there collecting them.  As Alien Spoons, I teach green wood working so will thin out the birch for spoon carving, shrink pots, bowls and other treen.  Maybe make some besoms and other products with it as well.    [caption id="attachment_41045" align="aligncenter" width="675"] Birch regenerating[/caption]  

  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.

Across the UK, there are several types of deer to be found in woodlands and rural areas namely : Red deer Sika Deer Roe Deer Reeves Muntjac Deer Fallow Deer Chinese Water Deer In recent times, the number of deer has increased and it is thought that there might be as many as two million wild deer in the UK - the highest number for many hundreds of years.  Unfortunately, deer can cause substantial damage to trees and woodlands.  Their feeding can cause a range of problems, which can include [caption id="attachment_34910" align="aligncenter" width="650"] Deer damage - bark removal[/caption] Stripping shoots, flower buds and foliage from plants Damage to woody stems, where a deer has bitten part way through the stem and then the shoot is tugged off - leaving a ragged end Eating the bark from younger trees. This mainly happens in winter when other food sources are scarce In addition to the damage associated with their browsing / eating activities, there is also the damage done by male deer who rub their heads / antlers against the trunks of younger trees.  This rubbing may be for scent marking or to remove the outer skin (velvet) present on a new set of antlers.  The antler rubbing results in cuts in the bark. [caption id="attachment_34415" align="aligncenter" width="700"] Remnants of birch woodland near Loch Muick are subject to browsing by red deer (especially in the winter), so temporary fences have been out in place to allow for regeneration and tree guards in place[/caption] Deer numbers are reduced by culling in order to supply restaurants, farm shops, and the hospitality sector with venison.   However, with the onset of the pandemic and subsequent lockdowns / restrictions  the demand for venison dropped significantly (as has price) so very few deer were culled.  Consequently, the number of deer is increasing.  Deer have probably gone through one or two breeding cycles since the first national lockdown,  and numbers are set to increase.   The increase in deer numbers not only affects the trees in a woodland but also plants of the herb and scrub layer.   The loss of plant species and aspects of the structure of the woodland means that particular microhabitats are lost so that species such as nightingales and warblers are at risk. Without careful management of deer numbers, woodlands could become much more ‘uniform’ as deer have no natural predators (in the UK).  It is important that deer numbers are monitored  as they will do significant (most) damage to woodland in Spring as there’s not much food elsewhere for them. Young trees are particularly at risk, unless they are protected.

Wind, fire and frost can seriously damage or kill trees.   Animals also wound them when they feed on bark tissues, and when they rub their bodies or antlers against tree trunks. Insects, like bark beetles can cause significant damage damage to woodlands and forests. The extent of damage to trunks and the bark of trees varies considerably in relation to the nature of the ‘attack’.  If the damage to the bark is severe and the vascular cambium is exposed then neither new water nor sugar conducting tissue can be formed.  Damage to the (outer) cork cambium (phellogen) will limit the trees ability to form the outer tissues of the bark - which protect the tree.  If the damage is restricted to the outermost bark layer then this will render the tree more susceptible to further damage (be it from herbivores or temperature extremes).

Most regard woodlands as a beautiful and important part of our countryside, and feel that they can exert a profound and positive influence on our emotional state.    Time spent wandering through the woods can have a relaxing and calming effect. Woodland only forms a small percentage of our countryside (about 13%), and some of that is dominated by conifers planted in the post-war period for timber production; however, the area covered by broad leaved trees is now increasing.    Despite this, our woodlands do harbour a wonderful variety of wildlife (think of the red squirrel, the nightingale, the dormouse) but there is concern that woodland plants and animals face a number of threats - many species are in decline.   Why is this ?

There are six species of deer to be found in the U.K. – two of which are considered native – Roe Deer and Red Deer.  The other species, Sika, Chinese Water Deer and Muntjac have been introduced in the last 150 years – and the Fallow deer is often accepted as part of our natural heritage as it was introduced back in the 11th Century. The range of Roe Deer (Capreolus capreolus) has extended considerably in the last 40 years, as have the numbers of Roe Deer.   The natural predator of the Roe Deer is the lynx, but this does not exist in the wild in the U.K – so the population has had one control on its numbers removed.  Read more...

Man has created the necessity for deer management by eradicating the natural predators of deer - the wolf, bear and lynx.  Escapees from deer parks introduced several non-indigenous varieties into the wild.  During the two World Wars, when manpower was limited, deer parks were left in disrepair and escapee deer spread.  With the formation of the Forestry Commission, land owners were encouraged to plant trees.  The aim was to create a national reserve of timber against future conflicts, but also created an ideal habitat for deer.  Improvement in farming practices provided more food. Deer Damage Deer are responsible for forestry and crop damage and, as they increase in number and range, more damage is now seen in gardens in urban areas. The damage they do to trees and plants are as follows: Fraying is damage done by territorial behaviour when deer rub and trash antlers on trees and shrubs. Browsing this is caused by the deer’s natural feeding and can kill or inhibit the growth of trees (note in the image below, small trees are the same age as the larger ones).  Has the effect of creating 'bonsai'. Control Measures There are numerous so called effective deterrents i.e. lion dung, sweaty socks, chemical agents and mechanical worriers, these are all short term solutions.  The only effective control is proper deer fencing put in by qualified persons, bearing in mind that roe deer can get under an 8” gap. Proper fencing is expensive and is not cost effective on large woodland areas therefore most areas have deer culling taking place in some form or another.

This generally has to be done in the field depending on how far one has to travel and disposal of the head, feet and gralloch should be by burial in the field (ensuring it is not near a water course).  Thus, taking other countryside users into consideration. Venison  Venison is one of the best meats to eat (recommended by the heart foundation) it is free-range meat with approximately 60% less cholesterol. The purchasing and eating of venison helps promote good deer management as they are looked at as a natural renewable resource,  instead of a pest. All six species of deer in the uk produce good quality venison,  although there is a slight difference in taste between them depending on what the deer have been eating and this can produce quite a unique taste.  It is recommended that a carcass be hung for at least three days to help venison mature, hanging for longer would produce a stronger taste (this should always be in a fly and vermin proof area and at 7 degrees C).
