Rhododendron ponticum revisited

Rhododendron ponticum revisited

by The blog at woodlands.co.uk, 30 March, 2023, 0 comments

In the eighteenth and nineteenth century, many explorers / adventurers brought ‘exotic’ plants back to the United Kingdom. These ‘exotics’ were planted in arboreta, botanic gardens, and some in gardens.  One bush that was introduced was Rhododendron ponticum. The plant is native to the eastern and western Mediterranean, and the Pontic Mountains, hence its name). It was introduced into Britain in the late eighteenth century, by Conrad Loddiges.  It was planted in Victorian hunting estates, also on heathland areas to provide shelter for game species. Its rootstock has been used for grafting of less hardy, more colourful types.  Many Rhododendron species are a delight and an adornment to our parks and gardens, indeed many hundreds of species of Rhododendron are known (many in China and the Himalayas)*.   Rhododendron ponticum has proved to be invasive.  It is a threat to key parts of our woodland ecosystems, such as Atlantic Oak Woodland.  Atlantic oak woodland is sometimes referred to as Celtic Rainforest.  It is characterised by lichen covered trees, growing amongst a rich moss and liverwort flora.  This woodland environment is damp and humid, to which streams and waterfalls contribute. These woodlands have evolved under the influence of the Gulf Stream,  which helps keeps warm and wet the area.  In some parts of the country, the woodlands have remained in their 'ancient state', since the last ice age.  However, these woodlands were more extensive but now exist as much smaller ‘pockets’ - damaged by grazing, pollution, and ‘exotics or aliens’ like R. ponticum. When this shrub ‘invades’, it 'takes over' and the woodland floor becomes a dark and barren place. A deep shade results from the thickets of the Rhododendron.  This results in the loss of much of the ground flora so that only some shade tolerant mosses and liverworts remain.  They form a ‘mat’ of dense vegetation that is a barrier to seed germination.  Even when the Rhododendron thicket is removed, the re-establishment of the original flora is compromised.  There is also evidence that as it grows this shrub produces chemicals which inhibit the growth of other species;  this is known as allelopathy. R.ponticum has spread in many areas, mainly to the West of the country. Each flower can produce several thousand seeds, so that a large bush can produce several million seeds in year. These seeds are tiny and wind dispersed; and though not all the seeds will germinate and grow, many will and colonise an area. Even when bushes have been removed from an area and the litter layer cleared, the seeds may persist in the seed bank of the soil - allowing the species to recolonise. In consequence, follow up over a five year period is really important. Recent figures suggests that some 37,000 hectares are affected in the UK.  Though the government does make a grant available for the removal of Rhododendron, progress with its removal has been slow. In Wales, there is a project called the Celtic Rainforests Project  (YouTube video link here) that focuses on invasive species and their attempted eradication in Atlantic Oak Woodlands in Wales.  With the agreement of the landowner, the project will organise surveys to identify the scale of the problem, and then contractors to carry out the work over the period of a management agreement, at no cost to the landowner [woodlands.co.uk has groups of buyers who have agreed for their various woods to be covered by such management agreements]. Clearing an area of this plant is difficult and expensive. An  effective first treatment to eliminate R. ponticum is to drill the stems, and inject herbicide directly into the plant.  This uses a lot less herbicide than spraying, and is a selective approach.  Mabberley’s Plant-book notes that the cost of eradicating the plant from Snowdonia was £30 M and that was in 1988.  Further information about the work in the welsh oak woodlands here. The plant is also a problem in Ireland. Indeed, referring to the Killarney National Park a politician has said “nothing short of calling in the army is going to put it right.” [caption id="attachment_39688" align="aligncenter" width="675"] Rhododendron ponticum growing near to the River Tay.[/caption] Forest Research has a number of publications about the management and control of R. ponticum. * Details of the genus may be found in Mabberley's Plant-Book.

Honey from the woodlands of Scotland.

Honey from the woodlands of Scotland.

by Andrew, 13 March, 2023, 2 comments

Beekeeping has a long and rich history in Scotland, dating back to the early medieval period. The country's rugged terrain and abundant natural resources have made it an ideal location for beekeepers, who have been keeping bees in the woods for centuries. In recent years, there has been a growing interest in keeping bees in Scotland's woodland areas. This approach has many benefits, both for the bees and for the surrounding environment. In this post, we will explore the historical aspects of woodland apiaries in Scotland, as well as the advantages of this approach to beekeeping. Historical Aspects Historically, bees were kept in a variety of different locations, including meadows, hedgerows, and woodland areas. In Scotland, woodland apiaries were particularly popular, as they offered a number of advantages over other locations. For one thing, the trees provided shelter and protection from the elements, which was particularly important in Scotland's often harsh climate.   Woodland areas also provided a rich source of food for the bees. In the spring, the trees would produce large amounts of nectar and pollen, which the bees could gather and use to build up their strength and numbers. This meant that the bees were able to produce more honey, which was an important source of food and income for the beekeepers. Over time, beekeeping became an important part of Scotland's rural economy. Beekeepers would sell their honey and beeswax to local markets, and the trade in bees and bee products became an important source of income for many families. Advantages of Keeping Bees in the Woods Today, there are many advantages to keeping bees in Scotland's woodland areas. For one thing, the trees provide a natural shelter for the bees, which helps to protect them from predators and harsh weather conditions. This means that the bees are more likely to survive and thrive, which is good news for both the bees and the beekeeper. Another advantage of woodland apiaries is that they provide a rich source of food for the bees. In addition to the nectar and pollen produced by the trees, there are often wildflowers and other plants growing in the surrounding area. This means that the bees have a diverse and varied diet, which can help to improve their overall health and wellbeing. Keeping bees in the woods can also be beneficial for the surrounding environment. Bees are important pollinators, and their presence can help to increase the productivity of local ecosystems. By keeping bees in woodland areas, beekeepers can help to support biodiversity and promote the health of local ecosystems. Conclusion Keeping bees in the woods has a long and rich history in Scotland. From early medieval times, beekeepers have recognised the many benefits of this approach to beekeeping. Today, this tradition continues, with many beekeepers in Scotland choosing to keep their bees in woodland apiaries. There are many advantages to this approach, both for the bees and for the surrounding environment. Woodland apiaries provide natural shelter and food for the bees, and can help to support local ecosystems. By choosing to keep bees in the woods, beekeepers can help to continue this important tradition, and ensure the ongoing health and wellbeing of their bees."

Proud owners of Coed Bwlch Coch

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.  
Sustainability sponsorship.

Sustainability sponsorship.

by Angus, 16 February, 2023, 0 comments

Woodlands.co.uk was chosen as the sustainability sponsor for the February 2023 conference, State of Open 2023.  Mostly held for those working in computing and data, this event was held at the QE2 centre in Westminster, with several hundred individuals who networked and learnt more about open source, open data and open standards.  The highlight was the speech by Jimmy Wales, founder of Wikipedia, explaining that Wiki isn't just about free and open information but about structure: their whole model is unusually open. It's truly democratic amongst wikipedians and is the antithesis of top-down models which dominate most of the world's organisations. As sponsors, woodlands.co.uk committed to plant at least one tree for every conference delegate as a carbon-offsetting measure and to encourage biodiversity. It turns out that at this conference relatively little extra carbon was produced for various reasons - the QE2 conference centre itself has strong environmental policies and the delegates were mostly either UK-based or were travelling to Europe anyway for a related conference.  Nethertheless many of them took away free eco-merchandise from the Woodlands stand, including seeds for planting and wooden pens.  Lots of the conference attendees were also interested in buying land for tree-planting so that their company would be offsetting its own carbon footprint and the staff would have a nearby place to go and enjoy. Sustainability sponsors can occasionally be accused of offering 'greenwash" but in this case there was no risk of that because the OpenUK movement is already so committed to sustainability and to using software to reduce carbon emissions.  And in this case, too, the sponsor was offering practical measures such as the planting of defined numbers of trees in the UK (in Kent) rather than a theoretical payment to a nebulous foreign project.  Conference participants were offered the chance to take away seeds to plant their own oak, cherry, lime, chestnut or sycamore trees. The role of sustainability sponsors at conferences varies but can involve financial support or the promotion of sustainability initiatives.  Some eco sponsors also offer energy audits, sustainability assessments or carbon footprint analysis.  According to the AI chatbot, ChatGPT, "Overall, sustainability sponsors play a critical role in supporting the transition to a more sustainable future by providing resources, expertise, and advocacy to organisations working on sustainability issues."  
Woodism and woodist ideas, which stigmatise woodlands

Woodism and woodist ideas, which stigmatise woodlands

by Angus, 13 February, 2023, 2 comments

"We're not out of the woods yet..." said Chancellor Jeremy Hunt in February 2023, warning that the British economy was still in danger.  It was widely reported by the BBC in ways that indicated the metaphor was apt and reasonable.  Hunt was unconsciously referring to the common idea that woodlands are dangerous and should be avoided, and that when we are out of the woods everything will be okay. This is in the same vein as stories like Little Red Riding Hood where she is warned not to talk to strangers when she has to go through the woods, and "woodist" notions like this are conveyed when the storyteller says "the woodcutter was never seen again after he entered the forest.".  This fear of woodlands runs very deep in our culture and creates a genuine barrier to their conservation and enjoyment.  Unfortunately Jeremy Hunt reinforced this fear, probably unwittingly. Such prejudicial language is perverse for a government which has just tried to burnish its environmental credentials with the 2023 Environmental Improvement Plan, part of which aims to "Enhance beauty, heritage, and engagement with the natural environment".  It's also surprising to hear such woodist language when the Forestry Commission's tree planting grants are over £2,000 per hectare higher where public access is given. More positive language about woodlands will be needed to achieve the Forestry Commission's aim of "boosting the country’s woodlands and timber industry." But Jeremy Hunt's prejudice and woodism is not new - for centuries people have feared the 'big bad wolf' lurking in the woods and the witch who is said to live in the forest.  Ideas of enchanted forests with traps and dangers are pervasive throughout literature and across the world.  In the past, people feared wild animals in woodlands that could attack and they knew that the forest is home to many dangerous plants and poisonous mushrooms, and in some cultures there are spirits of the forest which can be easily angered.  Many others in authority use similar imagery to Jeremy Hunt.  A Time magazine article by James Stavridis in January 2023 starts with a woodist stance: "Sadly, in these not-so-United States, we have found our way deep into a dark forest, and the question before us is how do we find the path out of this dangerous thicket into which we have wandered?".  Phrases like this which fight against nature are rife such as the expression that a report will be 'kicked into the long grass" implying to a place where no one wants to be.  Other anti-nature sayings are, "going feral" or "nipping problems in the bud". Many traditional stories indoctrinate children from a very young age such as the story of Hansel and Grettel who got lost in the woods leading to their being eaten by a witch.  And there were the three little pigs who were afraid of the wolf in the woods.  Stories make people fear getting lost and trapped in woodlands, having heard of Rapunzel who was trapped in a tower in the middle of the forest.   At least they were a place of refuge for Snow White who hid in the woods to escape the evil queen, or for Robin Hood and his band of outlaws who lived in Sherwood Forest.  And it's not just older stories that convey that impression - Maurice Sendak's 1963 bestseller, "Where the Wild Things Are", tells an allegorical story of a boy who misbehaves and is sent to his bedroom without his supper. But the tale is also about mood and behaviour: the woodlands which appear to grow in Max's bedroom are associated with him going onto a dark place.  Although it's sold as a children's book, it's just as much an adult's story, and it reinforces that strong link between woodlands and bad things. Much of the recent work to reduce people's prejudices around race and sexual orientation are fighting long-held and widespread stereotypes.  Ideally "woodist" language like Hunt's should be called out in the same way that racist and sexist language is - and despite woodist language showing a prejudice against nature rather than groups of people, it still affects how we view our world and how we behave towards others.  Perhaps we need a new lexicon of more positive language around woodlands, encouraging terms like "rewilding" and "greening".  Even the more jargony terms like 'eco-services' and 'biodiversity' are positive although it's more than better language which we need as an antidote to the woodist expressions of Jeremy Hunt.  What is needed is to make politicians ashamed of using woodist expressions and ask them to spend more time, well, in the woods.  
A camera for woodlands ?

A camera for woodlands ?

by The blog at woodlands.co.uk, 2 February, 2023, 1 comments

We, like many woodland owners, have stand alone battery powered trail cameras that record photos and videos onto a SD card.  They work well but obviously need regular monitoring to check battery state, and if the SD card is full.  Some time ago, I found a Reolink Go which is battery powered with the option of a Solar panel.  This camera records photos and videos onto a SD card, but differs from a Trail camera in that it has a SIM card. This allows remote access with live and remote viewing of photos and videos 24 hours a day. The daytime viewing is full colour, and black and white at night. There is sound, two way speech and an alarm all controlled from your mobile handset.  There is an option of "Push" notifications when the camera is triggered.  We live almost 50 miles from our woods and find it works well.  When I was researching the camera there was a review saying it worked well from 3000 kilometres but I cannot imagine many UK woodland owners would require it to work over such long distances. My original camera came with a V Sim which is a Vodafone data-only card, costing £4 per month with a monthly rolling contract.  These Sims are only  available via third parties now and are very expensive to buy but the subscription remains the same.  The cameras work on mobile Sims obviously using only the data aspect. The full technical data is available via the Reolink website and cameras are often discounted via the Amazon website..  There are other similar cameras, some more expensive but I do not have experience of these. We have seen deer, hares, squirrels, rabbits, mice, pheasants, extremes of weather and the occasional trespasser!  We enjoy the ability to see part of the wood from home when we are unable to visit.

December Monthly Mushroom - Purple Jellydisc (Ascocoryne sarcoides

December Monthly Mushroom – Purple Jellydisc (Ascocoryne sarcoides

by Jasper Sharp, 15 December, 2022, 0 comments

Looking out of the window as I type this month’s fungi focus, it is difficult to believe that but a few months ago we were at the tail end of a prolonged and intense heatwave and drought. Now as we plunge towards the depths of midwinter, the traditional mushroom hunting season is already well past its peak. Like heat and dryness, most fungi seem to have little tolerance for frost, snow and ice. But there’s no need to be too pessimistic that it’s all over for another year. There’s still plenty of stuff out in the woods and after several years of writing in these blogs about what can be found in any given month, as far as I’m concerned the season is never really over. “Seek and you shall find” is my chosen mantra when I head out with my camera. In fact, I perversely prefer the winter months to the brief but intense height of the season during September to November, a period that yields so many discoveries that photographing and identifying them all can be onerous and overwhelming, and when the forest floor is so dynamic it is difficult to know what species to make the subject of these monthly focusses. Winter is a great time to concentrate on the less showy side of the fungi kingdom; the crusts and the jellies and the other little things you might not notice until you actively start looking. This is the time to persevere with getting that ever-elusive perfect photo of such commonplace species as Candlesnuff Fungi (Xylaria hypoxylon), for example. It is most likely that in the process, while crouched amongst the crisp leaf litter, your eyes will wander and you’ll end up discovering something else you’d might otherwise never have noticed. Candlesnuff With this end-of-year windup for the winter, I decided to focus on a species that has just emerged over the past month that might be lingering a little longer while we wait for Spring. I’ve written before how jellies such as the Yellow Brain fungus and the various other types some refer to as Witches’ Butter manage to resist regular freezing and defrosting and can be found many months after they first emerge. To the list we might also add Jelly Ears and Tripe Fungi, but also another one I’ve not yet covered, which is the Purple Jellydisc (Ascocoryne sarcoides). These can take a variety of forms, from walnut-sized and brain-like to the more discoid example one might expect from its common name. They start emerging mid to late November, when the temperatures first start dropping, growing in clusters on dead deciduous trunks and branches – often beech but certainly not always – as if oozing from the wood. One might assume from the shape and texture that these are closely related to Yellow Brains and Crystal Brains, but whereas these other jellies are basidiomycetes (producing their spores on external structures), Purple Jellydiscs are ascomycetes (with their spores developing internally in sac-like structures called asci) - again, I’ve regularly covered this crucial taxonomic distinction, such as for example in some detail here. I would label the Purple Jellydisc a very common fungi, in that I’ve found it in every woodland I’ve ever spent much time in, although it is not as conspicuous as the other jellies. Yellow Brains, for example, seem to be appear quickly and fully formed, while Purple Jellydiscs seem to emerge small and grow slowly.  Black Witch I’m not entirely sure they are as durable as these other “true” jellies either; I’ve monitored a single growth of Exidia glandulosa, the Black Witches Butter, for a period of almost half a year, watching it dry, inflate, freeze and defrost through the seasons, but I am not entirely sure if I’ve really ever registered Purple Jellydiscs past January. These are also rather drab in the winter light too, more reddy brown than purple, and more opaque than glistening. They are consequently rather difficult to get a decent photo of, although with artificial lighting one gets a better sense of its blanched beetroot hues and jelly baby-like texture. This should all be enough for the casual nature lover to be able to look at a specimen fitting this basic description and to ascribe a name to it. As usually seems to be the case in mycology however, with the two near identical Yellow Brain species proving the point wonderfully, there are a handful of other species in the Ascocoryne genus that look pretty much exactly the same and share similar environmental niches. To prove this rather maddening point, just a few weeks back, I found a group of purplish discs growing in clusters on a fallen beech trunk that looked nothing like any other Purple Jellydiscs I’d ever found before, but they did fit descriptions of Ascocoryne cylichnium, which has the common name of the Budding Jellydisc. First Nature describes this species as “similar but its fruit bodies remain cup shaped rather than merging into a brain-like form.” So far so good, I thought, and if I didn’t have a microscope in my possession, I would have left it at that. But as First Nature also wrote, that “it can only be identified with certainty by microscopic study of the spores, which are much larger than those of Ascocoryne sarcoides”, I decided to dive in for a better look. At this point, I was also informed of the existence of a couple of further species that looked pretty much the same: Ascocoryne solitaria and Ascocoryne inflata. They could only be distinguished from one another and identified with any conviction through close microscopic scrutiny of specific structural details. Needless to say, they don’t have English common names. Anyway, to cut a long and potentially very tedious story short, I did look at my sample under the microscope and it turned out after all to be your bog standard Purple Jellydisc, Ascocoryne sarcoides, after all. I don’t think there’s much more to add at this point beyond a Merry Christmas and Happy New Year to all who have read this far!
Stick and flick, a possible solution to dog mess in woodlands. What to do?

Stick and flick, a possible solution to dog mess in woodlands. What to do?

by The blog at woodlands.co.uk, 8 December, 2022, 3 comments

One of the most read blogs is that entitled “Stick and flick, a possible solution to dog mess in woodlands”.  It also has elicited some very detailed comments.  It concerns the problem of dog faeces / poo that is left in woodlands and public spaces.   A NFU  survey in Scotland revealed significant issues associated with irresponsible access, notably livestock worrying by dogs,  the impacts of owners failing to pick up faeces after their pets, but also plastic bag pollution . Whilst, there is no shortage of dog fouling laws in the United Kingdom, the hanging of poo-filled plastic bags from bushes and trees has sadly become commonplace in many areas.   Local authorities in England and Wales receive many thousands of complaints about dog fouling each year. Not only is dog faeces a risk to us in terms of disease (due to bacteria such as E.coli and Campylobacter, plus parasites such as hookworms and roundworms), but it is also a danger to livestock through parasites such as Neospora, which can cause abortion in cattle, and Sarcocystis which affects sheep. Forestry England asks you “Bag and bin your dog's waste. Any public or household waste bin can take bagged dog poo.”  The National Trust has produced a Canine Code, like that displayed at Mottistone Manor, Isle of Wight (see below).  It offers sound advice for wherever you are walking your dog be it a National Trust property or local woodland.
