RECAP - CW 49/2024

Talking Trees with Lily and Jad . Welcome to Talking Trees . It's Sunday and that means it's time for our weekly wrap-up , where we revisit the key topics covered throughout the week .

All right , let's dive in . We're going deep this time . A whole week's worth of Talking Trees , the podcast that gets down to the nitty gritty of arboriculture , that's , the care and science of trees , you know .

Yeah , what's great about this deep dive is it doesn't just skim the surface . We're talking European tree care standards , how trees fight back against stress and even the challenges of urban forestry .

You know , for me , the highlight was learning about Neville Fay , a true pioneer when it comes to conservation arboriculture . His work with ancient trees , well , it's literally changed how we think about preserving these living monuments .

Right . And these standards , they're not just some rulebook for the pros , they're a framework for anyone . Anyone who cares for trees , making sure we approach them with precision safety , you know , with sustainability in mind .

So it's not just a chainsaw free-for-all huh , you really need to know what you're doing . And speaking of knowing what you're doing , let's talk about this thing called reaction wood . It's amazing how trees respond to mechanical stress .

Oh yeah , trees are incredibly adaptive . If they're leaning from wind or gravity , you know , they actually grow special wood to compensate Broadleaf trees like oaks , they develop tension wood which pulls them upright .

Like they're doing their own tree yoga in there .

Exactly . And then conifers . Like pines , they form compression wood on the underside of leaning branches . It pushes them back up towards vertical .

Now this reaction wood , it's not just some cool biological fact . It actually has practical implications , Like in woodworking right . Imagine building a table with wood that's going to twist or warp because of how the tree grew .

Right . So understanding those properties of reaction wood , it's super important for anyone working with wood .

It's wild how something happening deep inside a tree can have such a real world impact . And speaking of impact , let's shift gears to a more practical and sometimes risky side of arbor culture tree felling .

Yeah , even though trees give us so much , sometimes you got to remove them . Disease , safety concerns , development , all sorts of reasons , and that's when you really need a trained arborist .

One thing that really struck me was how they use ropes and pulleys to dismantle trees safely , especially in cities where space is tight . There's a lot at stake .

It's a high skill process . Definitely You've got to understand physics , tree dynamics , you calculate the forces , the weight of branches where it's going to fall , the impact on stuff around it .

So it's not just chopping down a tree huh , it's like a carefully planned operation .

Yeah , like a choreographed dance , Making sure each part comes down safely with minimal impact , thinking about the strength of the ropes , the angles , even the weather plays a part . It's all about minimizing risk for the arborist and everything around them .

Now let's talk about a hidden danger to trees , especially those living near roadsides Road salt , you know , those trees with the brown , almost burnt looking leaves , especially in winter .

Ah , road salt . Got to have it for safe driving in winter , but it can be brutal on trees . Messes , with their ability to absorb water and nutrients , leads to all sorts of problems .

The Talking Trees podcast highlighted two studies on this that were really interesting . One from back in 2003 went deep on the symptoms of salt damage . Helps arborists catch the problem early .

And then a 2010 study . This one was by the Rhode Island Department of Transportation . They were looking for solutions , trying to figure out how to lessen the impact of road salt on roadside trees .

Those trees have it rough , don't they ? Pollution , limited root space , and then salt on top of it all .

Exactly so this research . It focused on finding salt-tolerant species that could handle those tough conditions .

So if you live where road salt is a thing , take a good look at the trees along the roads . You might be surprised at what can survive out there .

Good point . And speaking of survival , let's move from dangers to being proactive .

Yeah .

Tree risk assessment . Trees , especially in urban areas , they need regular checkups , you know , to see if they're healthy and structurally sound . Like a physical for a tree , right , exactly . But instead of blood tests and x-rays , we've got a whole range of methods to assess a tree's health , from simple visual checks to some pretty high-tech stuff .

Because sometimes a tree can look perfectly fine on the outside but have serious internal problems .

Exactly .

So it's not just looking at the tree , it's understanding its mechanics , its history , its potential to cause harm right .

Absolutely . And then you've got specialized software that helps calculate the risk factors in the species , size , location , even potential targets nearby , Helps prioritize which trees need the most attention .

It's a whole detective investigation for trees . And speaking of organizations doing great work for trees , we got to talk about the European Agricultural Council , or EAC .

Yeah , the EAC . They're leading the charge for high standards in tree care across Europe . Huge role in professional development , research and raising awareness about how important trees are .

Their certification programs , like the European Tree Worker and European Tree Technician certifications . Those really stood out to me .

Those certifications are like a seal of approval . You know , shows an arborist has the knowledge and skills to really take care of trees . It's how you make sure that people caring for our trees are qualified up to date on the latest techniques .

And the EAC . They do so much more than certifications . They've got events , research , publications , and this year was special . The EAC celebrated its 30th anniversary three decades of promoting excellence in arboriculture , pushing for the care and understanding of trees all across Europe .

Their impact on the field is undeniable Healthier trees , safer urban environments and a greater appreciation for the vital role trees play in our lives .

Now get ready to be inspired , because we're about to delve into the incredible work of Neville Fay . This guy he's a visionary in the world of arboriculture .

Neville Fay you hear his name , you think conservation , arboriculture . He's dedicated , like over 35 years , to sustainable tree management , especially focused on ancient and veteran trees .

His approach . It goes way beyond just keeping trees alive , you know . It's about their ecological value , understanding their place in the ecosystem and making sure those living monuments are around for generations to come .

He sees veteran trees as living libraries , each one with its own story , its history written in its bark , its branches , and he believes it's our responsibility to protect them , to learn from them .

And his work has had a real impact , from managing the iconic royal parks in London to advising local governments on how to care for their trees .

He's shaped policy , guided research and inspired a new generation of arborists to look at trees through a conservation lens .

And speaking of protecting those ancient trees , we got to mention Neville Fay's work with the Ancient Tree Forum .

Yeah , the Ancient Tree Forum . They're a UK-based organization dedicated to conserving ancient and veteran trees , raising awareness , promoting best practices , advocating for policies that protect these living monuments .

So what are some of the ways arborists actually care for these ancient trees ?

One of the main principles is to intervene as little as possible . Respect the tree's natural processes . Only step in when absolutely necessary .

So let nature do its thing as much as possible .

Exactly Like with pruning , they keep it to a minimum on veteran trees .

Because too much pruning can actually weaken the tree , make it more susceptible to diseases and pests .

Another important technique is providing support for branches or cavities that are weak .

Like using props or cables to help distribute the weight and prevent further damage . It's like giving those old trees a little extra help to keep on going .

That's the idea . It shows how much arborists care about these trees , you know . And speaking of taking care of trees in our communities , let's talk about tree risk assessment .

Super important , especially in urban areas where trees are living side by side with people and buildings .

We've talked about how much trees benefit our cities .

They clean the air , provide shade , reduce noise pollution . They even make us feel better .

But they can also pose risks , especially as they get older or face challenges from their environment .

And that's where tree risk assessment comes in .

It's about identifying those potential hazards .

And figuring out how likely they are to cause harm .

It helps keep people and property safe .

While still allowing us to enjoy all the good things trees do .

The Talking Trees podcast gave a good overview of the different ways to assess tree risk .

Starting with visual inspections where arborists look for signs of decay or weakness .

And then there are more advanced techniques like sonic tomography .

But remember , removing a tree is always the last resort .

Arborists will try everything they can to save a tree .

Because they understand how valuable they are to our cities .

As we wrap up this part of our deep dive into the Talking Trees podcast , let's think about how all these topics are connected .

From the technical aspects of pruning and tree felling to the idea of trees as biotopes .

From the importance of managing salt and assessing risk to the role of the European Arboricultural Council and the inspiring work of Neville Fay .

Tree care is clearly a complex and multifaceted field .

It requires a holistic approach that considers the needs of the tree , the environment and the community .

But it's also incredibly rewarding .

Because trees give us so much .

They clean our air , provide shade , make our surroundings beautiful and connect us to nature .

So let's all do our part to ensure that trees continue to thrive for generations to come .

Whether it's planting a tree in your yard , supporting sustainable forestry or simply appreciating the beauty of a tree-lined street .

Every little bit helps .

Because trees are essential for our well-being and for the health of our planet .

So as we finish our deep dive into the world of arboriculture , let's remember what we've learned from talking trees . Let's appreciate the trees around us .

Fight for their protection .

Support those who care for them .

Because , in a world facing so many challenges , trees offer hope resilience and a reminder that we're all connected . Keep exploring the world of trees everyone .

And remember . Every tree has a story to tell .
