Dutch elm disease is beetles that move in when the tree is already dying. once the tree dies it falls. however, the disease doesn't effect the roots. elms are a sucker root system that continues producing trees. Dutch elm disease was bigged up in the 70's to give Satanists an excuse to destroy thousands of miles of healthy roots, by moving the hedge rows. Elms are described as the phoenix tree because of their regenerative ability. The beetle is just a normal part of the elms life. like the disease you are talking about in oaks. stress is their inability to cope. leave them alone, many will die, but from that resistant oaks will flourish. that's natural law.
Honestly, the growing list of new tree diseases frightens me, considering the low diversity of tree species we have in Europe (compared to other continents).
Kew gardens Pioneered a method of aerating the earth beneath their trees to aleviate the effects of soil compaction. The technique was developed after it was noticed that a poorly tree began to thrive after it was almost toppled during the Great Storm of 1987 - the entire root plate had been lifted and dropped back down! If the tree is already weakened then perhaps an application of subterranean decompaction would help alleviate some stress to help it mitigate the effect of age and disease. Perhaps make an enquiry of the Arboretum team there?
It amazes me that there wasn't any fence that prevents visitors from trampling the tree's root area. This is a common practice where a live (Belgium) to protect ancient trees.
I'm currently writing my bachelor thesis about sulphur-fertilization for oaks, so they become more resilient against all kinds of stressors. One of the stressors the institute performs test on is phytophthora and it is good to see that there are so many people will be invested in this topic! Carry on this work!
Epsom salts, magnesium sulphate or gypsum, calcium sulphate? I use both on all my plants indoors and out. Makes a huge difference to their growth and disease resistance. Easy for both to get washed out of a woodland soil, I suppose.
This is a worldwide problem. In New Zealand, the ancient Kauri trees _(Agathis australis)_ are imperilled by _Phytophthora_ dieback. In Australia, a similar threat is emerging for Bunya Bunya _(Araucaria bidwillii)._ To lose these tree species would be devastating, not only because of their particular cultural significance for indigenous peoples, but also because they are relict species essentially unchanged in hundreds of millions of years ("living fossils"). In the US, chestnut blight emerged in the 1900s and pushed a keystone species of their Eastern forests to the brink of extinction. It's dismaying that the short-term interests of international commerce continue to be prioritised over biosecurity and the environment. We know that floristry and the live-plant nursery trade are high risk for transmitting plant pathogens. We know that transporting earthmoving and agricultural equipment internationally is high risk, not only for soil microbes, but also for the introduction of invasive nematodes, ants, and weed seeds. But it's still happening.
Nobody ever logged out my grandpas property in Montgomery creek ca there’s still full grown pacific yews redwoods and California black oaks the amount of endangered flowers and other plants at his property is unbelievable oaks this size are all over the place hidden in a valley on his 52 acres from 299 to woodhill he’s got untouched land. Grew up the last 5 years of my childhood there big change from Tucson Arizona. To say the least what I get to visit whenever I want is priceless
This is horribly saddening, oaks in England already struggle, they need help, they are so important and one of the last bits of ancient English culture, there are such a large part of what the isles are, it would be extremely sad to loose, ash, elms and oaks due to disease so quickly, I sincerely hope they manage to pull through, but I am also scared since part of the management of ash dieback included chopping down extremely old trees, sure it was for the better but it lead to the death of extremely old trees, and I so deeply hate that it's so outside of our control, hopefully we find a way to protect them from the bacteria, however I have hope since old oaks have usually survived terrible diseases and have pulled through, they are left hollow and broken but alive, hopefully they can survive also this one
I have a big oak tree near where I live. I thought it had been hit by lightning as it's hollow and looked burnt, but apparently this is a sign of longevity. It's right on the rivers edge and we now have beavers again, having found their way here after being released elsewhere. I always wonder how old the tree is, it's very big, and whether in its youth if it ever saw beavers before they became extinct. It's a sandy bank and someone over time has let their dog dig all around it and now all the roots are exposed. I could see it was dying anyway but who knows how much longer now. Still, it's been a pleasure to see.
Its likely that it could of been hit by lightening, it usually causes quite a lot obvious damage through burning. But yes old oaks typically get heart rot and hollow out! Sounds like a cool tree - I think no matter where you are in the UK, we all have a personal oak that comes to mind.
@@weatherwatcher5303 along the river Tay in Scotland. I can see right through it. It has ferns growing on it as well as lichen. I will collect acorns this year and hopefully another generation in the future will enjoy it's offspring.
I'm from Ontario, Canada, and when I visited England, I went to Kew Gardens and saw this magnificent oak. It's the largest tree I've ever seen myself. Maybe one day I'll go out west and see the towering red woods of the Pacific North West. Until then, I'm sure I'll never see another tree quite as large and magnificent.
There's just something about Oaks that gives them a real character and personality, I can't think of any other tree that I feel quite the same way about
Norway lost all of our old oak forests (they could only grow in the south) from chopping them down for shipbuilding some centuries ago. They have never returned. We still have two species of oaks, but we don’t have any pure leaf forests. We also lost most of our elms (I think) to that disease sweeping Europe.
*This is incredibly interesting* ~ especially the part about what determines the health of a tree & how outer growth does not necessarily mean the tree is also resilient. 🌳 (I think this also applies to people, where the typical kind of "success" does not mean that they are also healthy, in particular their mental health) Thank you for another video with Oliver and your wizard friend. See you in the next one. 💚
Also The majesty Oak may be helped in part from some good mulching strategy, and possibly aeration of soil beneath canopy. Looks very dry and compacted under there and no deadwood kicking about on the floor.
They have statutory protection in the form of a Tree Preservation Order but it's a pretty weak mechanism. Ancient Woodland and Ancient/Veteran Trees are also regarded as "irreplaceable habitat" in the National Planning Policy Framework (NPPF). These trees are often also found in landscapes with other designations like a SSSI or similar. I agree though, not enough being done.
As an amateur mycologist im suspecting our distinct lack of agarikon fungal species that are key combatants of viral diseases in Europe has a large part to play in the desolation of our old-growth forests, Paul Staments points out that in the United States, there are far more species of agarikon fungus in their old-growth mycorrhizal biome and they are known to combat many different variants of infectious viruses. I wonder if we could inoculate large swathes of our old-growth forests with these protective fungal species. Agarikon was known to grow in Europe and the uk offering protection against viruses that they no longer posses however a complex combination of factors has led to near extinction of this ancient and essential fungus.
That’s really interesting. Does these fungus’s/fungi protect against bacterial diseases too? This video talked about three different types of bacteria that are causing the disease. I wonder if my country (Norway) has agarikon fungal species. But if they are to be introduced we should use those that have naturally been here before, European ones.
I think science is just starting to scratch the surface of the ecological importance, different roles and diversity when it comes to the whole kingdom of fungi.
My area of Ireland is full of ash trees due to limestone soils. They have all been affected by ash dieback in recent years leaving a lot of gaps in foliage in the woods here. I’ve recently heard about fire blight affecting hawthorn & rowan trees now too. I really hope oak isn’t going to be next.
It’s always hard seeing whole species of trees being wiped out by disease or insects. When I was growing up my house was surrounded by enormously tall oak trees- they were actually quite scary during storms due to their height as compared with their width. But one by one almost all of them died to oak wilt. I also watched entire mountains of pine trees die due to pine beetles.
Thank you for your wonderful videos, your boundless enthusiasm, your deep love for the British Isles' environments and your tireless work! Your beard looks great! You'd look cool & handsome in a full beard!
In NZ we have kauri die back. Kauri are one of our biggest trees the diameter of the trunk can be meters across and they’re known to live upwards of 2000 years, and in Māori mythology they’re related to whales. They’re dying off due to a fungal infection spread by humans and animals moving spores from tree to tree, they spread thru the soil very slowly on their own
Fantastic video, Oaks are my favourite Trees and trying to learn as much as I can about them so can show people our wonderful trees in Ireland. I've made a few videos on Oaks but know very little so thank you so much for showing the Maiden Oak, has to be one of the most beautiful trees I've ever seen in my life. Thanks so Much !
We should all keep an eye out, I'm sure its worth it to notify your local forestry Commission if you spot any of the Oak disease symptoms in the countryside around you!!
It was heartwarming to see you hug that tree 🌳 Rob. Maybe an exchange of your healing energy gave it some more energy to heal itself. It’s an absolutely massive tree!!
This is distressing news Rob. I do hope it doesn’t start to affect the oaks on our common. So true what you says about trees being individuals. Within a few yards from the edge of the common to the interior of the wood the oak’s complete morphology changes from a rounded spreading habit to tall thin forest trees reaching for the canopy and light.
Nobody ever logged out my grandpas property in Montgomery creek ca there’s still full grown pacific yews redwoods and California black oaks the amount of endangered flowers and other plants at his property is unbelievable oaks this size are all over the place hidden in a valley on his 52 acres from 299 to woodhill he’s got untouched land. Grew up the last 5 years of my childhood there big change from Tucson Arizona. To say the least what I get to visit whenever I want is priceless. Completely unrecognizable from the actual redwoods except in the summer time and dead of winter it snows and rains so much we even get summer monsoons.
Resilient woodlands - in terms of diversity, soil health, reduced compaction etc - should stand more of a chance in resisting AOD. Would be great to make direct comparisons over time between say old, traditionally managed woodlands and more recent plantations, both of predominately oak. Great video thanks for producing this.
With environmental factors and pollution changing so fast over a short period. Could this have an effect on the tree "stress"? Younger tress may be more resilient than older ones who have become used to a specific environment?
This is happening all over. We certainly have the same problem in the US. The factors contributing to it sometimes seem overwhelming…logging, air pollution, non-native species, global warming with its change in weather patterns, non-native diseases, stress to flora caused by all the factors hitting at once lowering resistance to native diseases...I’m sure I missed something. The presence of organizations like this gives me some hope, but without worldwide changes in how we, the human population, live the future still seems grim.
Very interesting But most saddening to hear about another of our native trees developing disease. This seems to be developing all at once throughout our tree species.
Since it's an infection, I suspect it wouldn't be a good idea to touch any of the bleeds or damaged wood. It's not at all likely that the bacteria would affect humans, but we could spread it to other still-healthy trees. We don't usually think of that sort of thing, but I doubt that any bacteria that landed on human skin would immediately die before there's any chance of spreading the infection.
Same problems here in Southeastern US. Everywhere I've gone, VA, NC, FL, MS, all oaks mostly in the red oak family are showing crown dieback, and the trunk bleeding. Here at our property the Turkey oak (laevis) is declining rapidly due to hypoxolen fungus invading the wood when droughts come along. Appears to me alot of these oaks wouldnt be here to begin with if wildfires were allowed to burn the vegetation and maintain the Longleaf Pines and keep oaks in more moisture retaining sites.
@@ConontheBinarian I'm not an expert, but when trees die of natural causes, I believe it compromises the timber. It would be a shame for this particular tree to go straight to firewood. Although depending on the cause of death, it might be best leaving it to rot away naturally. It's never been pruned after all. It's a tree as nature intended, with no input from man.
So strong growth may not equal resilience for trees? Does this mean the 'The Miyawaki Method of Forestry' could effect this resilience also? I'm no scientist but perhaps this is worth looking into also maybe. Keep up the great work everyone! 💚
You are absolutely correct. You all are warriors on the front line of the battle. Thank you for standing strong. And congrats on the sponsorship. You deserve it.
Literally the best VPN ad EVER!!! I watched the whole advert, and am actually listening to the info. Well done on a very creative sponsorship advert 🙌😂😂😂😂
Very interesting! You know why we still have trees and every other living thing, it's because of natural selection, the more we interfere with it the less effective it becomes and the more we need to keep interfering to keep it alive in the future, this is as far as i can tell not our fault, let nature run its course. As magnificent as that tree is there is a reason most things don't live forever and it's because they can't evolve, death is necessary for life
A tree with lots of growth and reproduction of flowers, seeds, like acorns, is not necessarily healthy. Under stress plants can put more effort into reproduction than other things, like mentioned in this video. During my degree i put a species of annual plant (Brassica rapa, oil seed rape) under different stresses, and though (as an annual plant with easily measured traits across a short timescale) it showed smaller leaves and shorter stem height and even fewer flowers, with poorer nutrients and growth conditions, the count of pollen from the flowers off all the plants through a particle counter never significantly varied. So a big tree may still look healthy if it is under stress as reproduction may be what comes first. Thanks for the vid, and for making me think about my biology experiment at uni after 23 years!
I am worried about our trees. There are a lot of sycamores around where I live and over the last 2 years I've watched Tar Spot Rip through them, every leaf of every young tree I saw last spring was covered in it.
According to rhs tar spot may look bad and cause early leaf drop but it doesn't affect the long term health of the tree. I've been a bit worried about oaks I've seen with very mildewy new leaves, it's something I've seen happen around warm and wet springs.
Good and interesting video, thanks! However, you may in the future wish to pronounce 'climatic' correctly. Climactic refers to climaxes, or orgasms, but climatic is, as you know, to do with climate.
The smaller growth rate in the year of drought could point to the trees ‘knowledge’ and quickness to shut down in reaction to the drought thereby retaining its healthy resilience, not opening it up to other serious risks related to poor drought stress related mechanisms. 'Power of trees' book discussed some of how the trees learn to adapt and be more adaptable, and how the learned experience to react to drought is beneficial. It would probably represent as a smaller growth ring. In a practical sense, perhaps its grows a denser (harder) layer in that ring also making it more physically resistant to pest and disease. What about chemical composition in the growth layer and its ability to either produce, or be comprised of disease/pest resistance? Thirdly, what about ecological / environmental tipping points, and the role trees play in the climate / environment. Are our tree Bourne diseases ecologically mastered to alter rebalance ecosystems shifts - more wood on ground, more water retention, new tree growth, increased carbon sequestration…. Or is it a tipping point where by the extant of the ecosystems is so damaged it takes a few ecological thresholds to knock back until it can ‘return’ to what it is now. Think - trees collapse and carbon shifts from soils to the atmosphere until soil fixing is repaired (through decomposition of trees and dying animals as a result in shifting ecosystems and habitats) whilst grazers keep down any new growth and die off themselves, until such time that vegetation can be the primary trophies driver once again, and things ‘return’ after such cycles of knocking back through ecological systems. For example!?!?
@@mr.lonewolf8199 there are, many of them if you look, i'm sorry I don't have the time to link one right now, but as an environmental science student, how plants react to climate change and such is often an important topic, still besides that investigating it more thoroughly will never do any harm
That was awful. I'll probably unsub if you keep doing these advertisements. Nothing personal, it might even appeal to a different audience, so if that's the route you're going then good luck.
I think if you support the channel and me as a creator you should be able to stomach the advertisements. This channel takes a lot of time and I cannot do it all for free, as much as I would like to. Just so I understand what you didn't like, was it the integration of the advertisement itself, or how it was done... I understand that Wizzard may be an acquired taste.
Great Video! You should make a video on the e woodii there is only one left but its a male and they cant find a female. I believe the last one is a Kew gardens but i am not sure. It could be quite interesting?
