Much has been written about the explosion of the UK deer population in recent times, and the damage to woodlands through their browsing activities.  However, the grey squirrelis associated with tree damage.  The grey squirrel is not just the 'cheeky chap' who steals the bird food in the garden, it is a serious pest.    The grey squirrel is a non-native species.  It was introduced in the 19th century.  The squirrels have spread across the country and have displaced the native red squirrel from many areas (either through competition or disease).  The grey squirrel's bark stripping activity now poses a threat to the sustainable management of woodlands. Gnawing of the bark means that they can get to the sweet, sap filled tissue (phloem) just beneath the bark. This tissue is responsible for the movement of sugars and other organic molecules around the plant (known as translocation). If the gnawing extends around the stem then the tree is ‘ringed’ [i.e a complete circle of bark and underlying tissue is removed]  then the tree us likely to die.  The squirrels tend to take bark from the main stem (and branches). The bark stripping may : Lead to the loss of particular tree species (for example, beech) Lead to the loss of insect / spider and fungal species associated with the loss of tree species, i.e. a loss of biodiversity allow fungal infection of the tree Reduce carbon capture Reduce the economic value of timber Act as a disincentive to creating new woodland for timber In order to reduce squirrel damage, it is important to Start inspecting for damage in late February as damage typically occurs in early Spring.  Examine the base of trees for damage. Look for ‘tester patches’ made by squirrels (to which they may well return later). Check young, broadleaf trees as they are particularly favoured by the squirrels.  Oak and beech are quite vulnerable to damage (see image of damaged beech trunk below). Recent research* at Bangor University has investigated the microbiome of the squirrel in relation to its bark stripping activity.  The microbiome of the gut refers to the various micro-organisms found with the intestines.  Analysis of bacterial DNA found in the colon of great (and red) squirrels revealed that grey squirrels had 'oxalobacter' bacteria in their colons.  These bacteria are able to 'release / access' calcium from the tree bark to the squirrels.  Calcium is an important nutrient in terms of bone building and is also involved in muscle contraction. had  a more diverse bacterial population in the colon. These findings may help explain why the grey squirrel 'outcompetes' the red squirrel.  Their more diverse gut microbiome may mean that they can access a greater range of resources. For example, grey squirrels can digest acorns, which red squirrels cannot;  this is possibly associated with tannin content of acorns. In order to reduce damage in a woodland, the number of grey squirrels may need to be managed.  This can be done though trapping or shooting.  Trapping is a legally acceptable and effective way of controlling grey squirrels in most situations. Grey squirrels can be trapped throughout the year though March to September is a good time as food is less abundant. Through autumn, berries, nuts and seeds [natural foods] are available so trapping is less successful.  Details of the various types of traps and their use / placement may be found at: https://greysquirrelcontrol.co.uk/trapping-method.php https://www.britishredsquirrel.org/wp-content/uploads/2016/07/Grey-Squirrel-Best-Practice.pdf https://basc.org.uk/pest-and-predator-control/grey-squirrel-control-with-live-capture-traps/ https://www.britishredsquirrel.org/wp-content/uploads/2016/09/Trapping-Protocol.pdf  https://bpca.org.uk/a-z-of-pest-advice/squirrel-control-how-to-get-rid-of-squirrels-bpca-a-z-of-pests-/188983 To go down the ‘shoot to kill’ route then there are a number of rules and regulations to observe.  Details may be found in the link below : http://www.britishredsquirrel.org/grey-squirrels/grey-control/ It is hoped that eventually a form of oral contraception will be developed, which will offer a non-lethal and humane means of population control.

Willow bark and the covid virus. The Covid pandemic created great strains on health and business services, and the virus continues to impact society in many ways.  It is not surprising that there is an ongoing search for anti-viral agents. Finnish scientists have found that willow bark may have a role to play. Willow bark has been used as a natural medicinal product over the centuries as an effective agent to treat pain and inflammation.  The anti-inflammatory properties of the bark are generally ascribed to salicin, which was to lead to the development of acetylsalicylic acid, that is aspirin.  The Finnish scientists ground up the willow bark in hot water and then sieved it to create an ‘extract’.   This solution was then added to a number of cell cultures that were exposed to different viruses (enteroviruses, a seasonal coronavirus and SARS CoV2).  They then monitored the viral activity, cell infection and viral replication  The extract had an effect on all of the viruses.  In some cases, the extract affected the envelope of the virus (a structure surrounding the viral genetic material) so the viruses essentially broke down, whereas others were prevented from releasing their genetic material and reproducing.  Specifically, though the Covid-19 virus could enter cells when treated with the extract, it could not reproduce once inside. The research team analysed the extract’s chemical composition and tested some known constituents of bark but concluded the success of the extract probably resulted from the interactions of different biologically active compounds.  Compounds in the extract included many complex chemicals (for example, hydroxycinnamic acids, salicylates, flavonoids, flavan-3-ols, and proanthocyanidins (polyphenols).  Further work will focus on the role / interactions of these various compounds. The Hazel Dormouse in peril. The numbers of the hazel dormouse have fallen dramatically since the turn of the century.  The dormouse has disappeared from Staffordshire, Northumberland and Herefordshire in the last few years.  This loss is attributed to The destruction / fragmentation of their habitats Poor management of woodlands and hedgerows, leading to a loss of diversity / niches Rising deer numbers, feeding on saplings and shrubs Extreme weather patterns may also play a part Captive-bred dormice have been re-introduced to some 25 sites in 13 counties across the country, sadly nine of these reintroductions were not successful.  Dormouse bridges have been created to enable the animals to move between areas dissected by major roads (such as the M1), others are planned.   The dormouse (Muscardinus avellanarius) is a nocturnal animal and lives mainly in deciduous woodland,  it feeds among the branches of trees and shrubs. the dormouse rarely descends to the ground.  It feeds on a wide variety of 'foods' ;  flowers (nectar and pollen), fruits (berries and nuts), certain buds and leaves and some insects, such as aphids and caterpillars. The hazel dormouse is regarded as a ‘flagship species’, that is to say, if the dormice are thriving then it is likely that other species are too from butterflies to birds such as the nightingale.  Dormice are currently assessed as ‘Vulnerable’ to extinction in Britain under IUCN Red List criteria, but recent studies suggest a classification of ‘Endangered’ might be more appropriate.  Certainly, their future is uncertain. Detailed information on the hazel dormouse is available at PTES (note this link opens a PDF).  Their report details the state of hazel dormice in 2023. zsaqwa https://youtu.be/4u-yMkXOuTY Changes in the Boreal Forests. Boreal forests encircle the northern reaches of the Earth, lying just below the treeless under of the Arctic.  These forest cover large areas of Alaska, Canada, Scandinavia and Siberia.  These forests contain billions of trees, most are conifers but birch, poplar and aspen may also be found.  The trees (and soils) contribute significantly to the cycling of carbon in nature, absorbing carbon dioxide in photosynthesis. They are also home to many species of migratory birds, plus predator species such as lynx and brown bears, and wandering herds of moose. Due to the remoteness of these forests, they have remained (until relatively recently) unaffected by human impact.  Now these forests are warming at a rate above the global average.  This has a number of effects:  In the southern parts of the boreal forest. Conditions are becoming too warm for cold adapted trees; their growth is slowed and they may die. With the warming comes increased dryness, which leads to water stress and increased risk of insect attack /  infestation. The dryness also means that forest fires are more likely and occur with increased ferocity.  This year, the fires in Canada have been particularly extensive and damaging.  Some 18.5M hectares went up in flames.   The plumes of smoke spread far and wide. [caption id="attachment_40597" align="aligncenter" width="675"] Canadian forest fire[/caption] Scientists are now using satellites to track changes in the extent of the boreal forests.  If trees are being lost on the southern edge of these forest, then it might be expected that the northern limit for tree growth might change.  Indeed, there is some evidence for this in Alaska where young Spruce are now growing some 25 miles beyond the previous tree line, moving into the ‘treeless tundra’.  It may be the loss on the southern edge is compensated by extension of the most northern parts of the boreal forest, but it is not clear whether tree can ‘move’ at the rate of climate change.  

In 2022,  we made a decision to buy Coed Bwlch Coch from woodlands.co.uk,  just over four beautiful acres of woodland near our home in mid Wales. Although we knew nothing about woodland management or forestry my partner and I love the outdoors. Just how important this is became apparent when I had breast cancer some years ago - I even camped out near the hospital during my treatment regime. It took less than six weeks to gain ownership. Woodlands.co.uk had two superb representatives on the ground, Ash and Helen. They opened our eyes to the possibilities this gorgeous strip of woods held. They answered all of our novice questions and guided us with ease through the buying process. We have been so impressed with the sensitivity and care taken by woodlands.co.uk to prepare the whole forest for sale. We’ve only owned the woods for a few months but we have already enjoyed dozens of visits. Our first task to cut back loads of brambles in one area where a bit of old stonework was peeking out has revealed a treasure: the ruin of a stone longhouse that pre exists the 1840 Welsh Tithe Maps on land once owned by the Earl of Powis. We are taking baby steps to learn- we’ve invested in some training courses, some decent outdoor clothing, some second-hand tents and handbooks. This year we’ll do some coppicing, harvest firewood for home, build a store, make some charcoal, camp, bring all our friends and family ... but mostly we will feed our souls.  

The Duke of Burgundy (Duke) is a beautiful rare butterfly which has a colony in Denge Wood. Its two main populations there are at Bonsai Bank (Forestry England) and the Warren (Woodland Trust), with individuals found in other parts of the wood linking them. They fly in May, with a few emerging in late April if the weather is warm, and by June they are gone until next year.  Dukes are small butterflies, being not much bigger than a thumbnail when they close their wings. The males and females look the same unless studied closely, but behave slightly differently. The males tend to bask in the sun and perch on vegetation up to 1.5m high. They are quite territorial, so can often be seen flying to battle with interlopers. The females are more secretive, and can sometimes be seen laying eggs on Primroses or Cowslips. Dukes sometimes take nectar from flowers and particularly seem to like Wood Spurge.  Read more...

My parents and I have recently purchased a piece of woodland of about 3 acres, in Devon, called Beauchamp woods. It is a mixture of semi-natural ancient woodland, larch plantation and a clear-felled area. This is the perfect mixture for us. We wanted to give something back to nature by preserving a small piece of habitat for wildlife, whilst enjoying spending time in our woods. We are loving it and find it very rewarding. I have some knowledge of woodland management and conservation through my education and work and it is great to have the opportunity to put this into practice. My main aim is to maximise biodiversity, I want it to be the best habitat for as many species as possible. Read more...

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 ?

The arboretum at Tortworth is a very special place. It has a long and interesting history and boasts some incredible exotic trees. The trees are a living history of the woodland and the family that planted it, but a few years ago the collection was at risk of decline through lack of management. That is, until 3 years ago when woodlands.co.uk purchased the woodland and the trees were given a new lease of life -  while also changing lives.   The 20 acre site is now managed by a community woodland group who are gently restoring the trees and at the same time, making a difference to people, as we hear from one of their regular volunteers.

Peter Fiennes immersed himself in British woodlands for a year and he dug out every literary reference to woodlands that he could and visited dozens of woodlands to appreciate their magic.  The result is an erudite and inspiring tome that is also a cry for help to preserve any ancient woodland that we haven't already destroyed. "Sell everything! Protect the land!" exclaims Peter.  He outlines a five-page action plan to protect British Woodlands which he also describes as a statement of the "bleeding obvious", including creation of more woods and visiting the woods more often.  When he joins one of the Woodland Trust's campaigns to protect an ancient woodland near Sheffield from development he becomes apoplectic: "An ancient wood for a service station.  What sort of sick exchange is that?"
