- This time we're looking at the beautiful and bizarre Eucalypts and the creatures that rely on it to survive. Love them or hate them, they're perfectly adapted to living on this hot, dry continent.

Saying "they can photosynthesise on both sides" (3:15) is a bit of a disservice to how interesting trees are.
Normal trees, for example a lemon tree, have one side of the leaf which always faces the sun and one side which never faces the sun.
As a result of this they developed one type of tissue on the sunny side called palisade mesophyll which is densely packed with chloroplasts and has an epidermis covered on thick wax to reduce water loss. The underside contains all of the stomata and the spongy mesophyll adapted for gas exchange- letting CO2 in and O2 and water vapour out. This loss of water vapour is why the plant tries to keep this tissue on the shady side.
Both sides of the leaf are necessary for photosynthesis.
Because of that weeping habit you described, it is much less likely for many Eucalypt species to have a defined sunny side and a defined shady side- one side might be in the sun at 10am but then in the shade at 3pm. These species have therefore adapted to have stomata and palisade mesophyll on both sides of the leaf. We call these species "concolorous" because both surfaces of the leaf are the same colour.
But there are also species like sugar gum E. cladocalyx which are "discolorous" like the lemon tree described above with defined sides for spongy and palisade mesophyll.
Keep the vids coming mate! The quality and your deap-pan delivery are exactly what we need to show off Australia's epic flora and fauna!
Totally agree.
Great video, thanks!
Deap pan?? He's not cookin bloody pizzas mate 🤷♂😂
We took them to California in the 1850's thinking they were some great wood producers. an aussie guy tried to set up a business selling them, they never took off but he planted a lot of trees which are now getting to full height, and now we have different weather conditions and it is going to end REALLY BADLY in the next few years. T'm so glad i'm here for the final chapter of the series "how stupid are humans?"
I saw them at the foot of the hill in Bernal Heights Park in SF recently and was floored that they were there. I assumed they were introduced by humans, but I was amazed that balmy, cool, damp San Francisco could grow trees adapted to such extremes. Interesting to know their backstory, thanks!
I feel like it's been known since the times of ancient Greek that Eucalyptus is poor for would and paper production, but what did they know, right?
Top tier mate, love your work. You will get big if you keep this quality up
I agree 😁👌
My boyfriend said the same thing when he bought me a penis pump
Totally agree, great work 👍
Agreed, I'm upset there's only 3 videos. That's a good thing.
Came here after accidentally stumbling on your magpie video and instantly subscribed, mixing education and humour is a recipe for success
They are all over in Ethiopia 🇪🇹 . They are almost the national trees. The story goes by Ethiopian King, which went to Australia and got the seeds as a gift.
Greece and California too.
You've got a lot of Aussie fans who are keen for more of your content! A testament to your skills and presentation style
And I must say, Vivaldi is an excellent touch!
I was disappointed to see you’ve only done 2 videos. I enjoyed both very much and I’ll definitely watch them again. I love eucalyptus and have about 40 propagating in the greenhouse and the threatened Eucalyptus synandra at about 30cm in height in the backyard.
Australian flora: resilient, beautiful, successful
Australian fauna: smooth brained, endangered, cute tho
Our son has eucalypts in his suburban yard in South Australia. It is part of a koala corridor.
The best tree of all 👌
We take them for granted but now and then you see a massive beautiful gumtree, I love em
These two videos have been great to watch especially since Australian flora and fauna are so often overlooked in nature videos. So keep up the great work! 👍
I just subscribed to your channel today after watching your magpie video. You’re brilliant! Love your work.
I lived in an area heavily affected by the black Saturday fires - watched over the years as the acres of blackened gum trees sprouted up with new growth. They're tough buggers, and you can't help but be heartened by how resilient nature is. Keep up the great videos!
I grew up on the Murray River, and some of the River Gums along the bank are absolutely magnificant. Spent many a summers day as a kid climbing in, and falling a long way out of, the mid upper regions of those trees (seems strange calling them just 'trees') looking for the best spot to tie on a rope swing. Never broke anything but got nicely winded hitting the water from about 20 meters up once 🤕
Another great video man! Learnt some things , had a laugh.
You're doing great!
The algorithm's got you in its claws because YT recommended your magpie video to me right after you uploaded this one!
Your video style reminds me of a channel I've been watching for years, Ben G Thomas. Informative but with bits of silliness injected in to add humour and help keep those with glider-style attention spans engaged, clear narration and a set format with a nice intro. Subbed!
Ive always loved Maggie's... your video was great. You are easy to listen to and I like your simple humour. Keep it up please and ignore any negativity please. I hope your channel does well for you
I don't thumbs up videos normally, but your content is exceptional and definitely a GOAT in the making
The self pruning of gum trees is a looming threat around built-up areas of the Bay of Islands. They were brought to NZ early in the piece for wind breaks and firewood but they liked the climate so much that they bolted upwards, meaning the logs were not as useful for lumber as hoped for, apart from the red gum, but it's not so common.
Educational content with humour sprinkled in is some of my favorite content and you are making some great content. I hope to see this channel grow
Another great video!
These videos are so enjoyable, yes please make infinitely more. I'm moving to Australia, I've always loved it and it has always felt like home and it's difficult to find videos like these to show my family in the US aussie flora and fauna. I'm always searching for many many just clips or recordings of birds and their noises along with terrain and vegetation. I don't always catch things myself on video when I'm visiting Australia so it's a smidge frustrating when trying to explain things or show them. These videos are informative and they make me laugh at the editing. They're absolutely perfect lol. Thanks for your hard work indefinitely!
Australia's landscape is majestic and unique but you'll be giving up many of your freedoms and may be required to be poisoned should you wish to work.
We're full
I'd stay in the states....... nice for a visit, but as a lifelong resident, citizen, this place has seriously degraded in the past 30 years. I would leave my options open.....
"I've always loved it and it has always felt like home' bahaha wtf?
How lovely that you feel like this is your true home❤ ignore the yank bashers. Some of us forget that heaps of us come from immigrants, in my case Italy.
You'll end up knowing more about this country than many inhabitants if you keep educating yourself like this!
Another great video! This channel could blow up with this level of quality!
Great work mate. You should definitely branch out!
wow, just found your channel. Love it. Eucalypts are beautiful and I have 8 giant gums in my backyard. The two biggest are the ironbarks. The yard backs onto a reserve and is a subtropical rain forest.
Wow whereabouts are you

Letttssss gooo I hope this channel does really well ❤️🔥
I live in California where we have eucalyptus trees growing everywhere like weeds. We love them. If you age the wood it makes a wonderful, long and hot burning log in the fireplace.
Can you guys send to vic? Communist Government wants to try and ban wood burning heaters.
The government is shutting down logging.
A good split red gum should be weathered for at least 2 years. Some people say at least 5 years but realistically mostly weathered /aged for 12 months.
I usually mix red gum with peppermint and other gum it regulates heat nicely.
Most species do, but many are to precious to burn, making beautiful woodworking timbers
Fantastic!! Great Video mate about our favourite birds. 💜❤️👍🏼
Great vid
Love the vid! Love learning about the things around me that I didn't appreciate until now!
Loved both this and the last video - keep it up!
Just moved to Australia and I know I'm going to love learning from this channel ✊🏾
Welcome mate. Where are you from? And where have you settled?
A great video. Please don’t stop.
Keep up these quality videos 👍
Excellent job mate.
A fabulous production. Thankyou.
Love seeing the Australian flora and fauna, and these videos are so well made, keep it up!
From here in the States we thank you for sharing this excellent video and wish you the best of luck!
On a holiday in Crete, Greece at the moment. Plenty of Eucalyptus trees here. I think they were imported at some point and then began to thrive in the climate up here
Commenting for the algorithm, and to let you know that your videos so far have been fantastic. Love your presentation style, the jokes, and also learning about local flora/fauna. Can't wait for more!
Wow I never had a second thought of these trees, but this vid made me appreciate how amazing seemingly mundane things could be.
I love this channel! Relaxing and informative, the best combination.
Fascinating. Never clicked in my brain before the connection between eucalyptus oil and the intensity of the fires, and never knew that was the cause of the Blue Mountains haze.
great delivery and excellent editing. Subbed!
A bonus tidbit about ironbark is at one time they were highly sought after for the construction of hulls on the early ice ships. As the wood is incredibly dense and hard. Apparently the wood would splinter instead of cracking.
Once I dropped a hammer on some grey ironbark flooring.
It bounced.
It’s also great for a long hot burn, as firewood.
And making bass guitars from
Part of the reason they're so adapted is due to indigenous practices who used to regularly do controlled burns for thousands of years which not only create agricultural territories but also reduced the buildup of leaf litter and other flammables which mitigates the damage of uncontrolled burns common to the country. Now that we've stopped doing it so regularly we suffer much greater damage
Prolonged droughts from anthropogenic climate change probably don't help either
I believe you are correct in stating Eucalypts are not always the reason for large fires spreading.By way of contrast some of the worst fires in the Canberra area in 2003 were attributed to some of the Pinus forests located in the area.
Keep these coming for sure Australia has great native plants and wildlife. 10|10
Amazing video 😊
Look forward to see more 👍
Bloody rippa cob, keep it cookin
Working in Native Foresty on super hot days we had to down tools because a small spark of a machine on a rock could start an inferno. Gotta love a tree that needs either fire or snow (sometimes both) to germinate.
Even old dirt bikes can shoot sparks from the muffler if they don't have an exhaust arrestor. Chainsaws can't be used in Summmer either
You're the guy who did the Magpie video. Toxic dating advice videos have been rotting out my brain lately, so it's refreshing to have another video like this pop up for me.
It's rough out there, take care bro
How truly wonderful to learn everything about Eucalyptus trees, Koalas and Flying Gliders from you. I enjoy your relaxing voice, and touch of humour. Thankyou so much 😊
Just the sort of content I was looking for, would love to know more about all our amazing plants
What an awesome channel. I really like the recognition that your giving us Aussies. I see this channel going a long way with this level of production quality, and relaxed vibe.
I never thought I would be so interested in eucaplyts but you have truly surprised me this was very fun and informative to watch.
Love it. Well delivered, humorous and educational. Awesome to hear our Aussie accent in such a well made video ❤
Fascinating and funny! Looking forward to more!
Love your work, you're filling a niche of australian sci-comm content that I've been feeling a need for. Keep it up, man!
Oh man, you are brilliant! This is one of the best videos ive seen in ages.
Love the videos and look forward to more. Your delivery is great, mixed with humorous comments.
I like the gum tree, got one of the different 800 species in my yard. definitely learnt some new things about them from your video. You did forget to mention that they are one of the thirstiest trees around, strange for the driest continent.
They suck up as much water as possible when they can so that they can last through droughts
? The Goldfields region has a very diverse range of eucalyptus endemic and it has a rainfall of around 250mm (10"). This is a pretty arid climate
They cover the whole continent and have adapted to every soil and climate type
During my lifetime of 70 plus years I have seen an expansion of forests.
Australia once had mixed forests which have now been replaced nearly entirely by eucalyptus.
Excellent video mate, with very well researched info and the added touch of typical Aussie humour is awesomely entertaining. We laughed heaps, thanks! Really looking forward to many more videos, keep them coming. 💜❤️👍🏼
Please make more, really enjoyed both of your videos, high quality, fun, educational and very wholesome =)
Nice job! Not what I expected but informative, uplifting and entertaining -all wrapped up into something just the right length for my attention span. Thanks mate.
Damn... As an Aussie, I learnt something, and also was entertained...
As a builder, I froth a all of my seams when I get to salvage Blackbutt or River Red from the homes areound NSW.
feel like it’s so rare to see such great, top quality UA-cam videos particularly on Australian biology (on plants and animals) - keep it up!
Brilliant as always and an excellent quick foray into our beautiful iconic Eucalypts.
Love this video. Funny and very informative.
This is the sort of top tier video that makes my day, incredibly well done mate!
I love your videos! They are not only entertaining but informative as well. Thank you for sharing them! ❤
Great topic. Hugely informative. Enormous potential. Please keep up with this important journey.
really enjoyed this, was going to keep scrolling but something caught my attention and im glad it did. thank you for making this, will stick around to see the journey of your channel!
As someone named after the tallowwood eucalyptus tree, I approve of this message
I've been a transplant (tree puns ha) to Australia for over seven years now, and I've always been drawn in by the bush--there's something so magnetic to this country's nature, but I've never been able to put into words how and why it makes me feel a certain way. Your narration here, though, touched me deeply, especially when I could hear the pride in your voice when you were talking about the centuries-old eucalypt in Melbourne. Something about it made me tear up. Thank you for putting your wonderful work out there ❤
In saying you are a transplant. May I ask the origin of your sprouting? Here in Tasmania we have had an influx of people from different origin since Covid and since we have been isolated geographically I do have an interest as to why. My ancestor was sent here during the machine wrecker riots in England in the early 1800 so it was not my choice but at this point I can’t see myself anywhere else. I spent 6 and a half years in tropical Townsville but Tasmania is home.
@@garryrichardson4572 I'm originally from South East Asia. I arrived, at the ripe old age of 19, for uni (got a decent scholarship), but stayed for work and then started a postgrad degree by research. My husband and I are not yet permanent residents, but we're working hard to get there, since we can't see ourselves putting down roots anywhere else.
@@clumsyfeetsies cool.
Please keep at it. You're informative and interesting and you don't speak down to us, you just speak to us.
Saw your magpie video shortly after it was uploaded and immediately subscribed. And this video is just as amazing, hilarious, and informative. I’m an American hoping to immigrate to Australia within the next 2-3 years, so these videos are fueling my interest and desire to learn. Please keep them coming!!!
Make sure you bring a tent! Good luck trying to find a house 😅
Biggest problem with Eucalypts - us and the fact we do nowhere near enough cool quiet burning of the landscape.
Was super surprised when went to your channel and saw that there were only two videos, and I'd already watched both of them! I'll definitely be subscribing and watching for more, the quality already feels like a channel thats been around for a while!
Me2. Such high quality takes time. Be patient.
Bloody awesome stuff mate. Your channel is going to explode if you keep this up. Top tier
Really interesting commentary. Especially the fact that the oils cause fire to rage quick and hot and leave the interior untouched! Grateful for the measurements supplied in Victorian units. Hahaha!
The Aussies who built our highways here in NZ planted eucalyptus alongside them, resulting in a certain type of eucalyptus being a common site now. Not sure what kind they are but theyre tall, pushing 100 years old now and their bark is beginning to fall on most of them showing a smooth whit trunk underneath
This video is fantastic. Informative, good writing, and super cozy. Awesome 👍
Loved this. Your videos should be extended to teaching in schools. Informative, interesting and delivered in the most fun aussie manner.
absolutely loving the videos, keep up this quality please i would love to watch more of your content
The Fevola reference is bloody spectacular mate, bravo. Your videos are wonderful, keep it up
Looking forward to more vids from you, we now call Australia our home and you have a great way of educating us about what lives and grows here, the humour is a great touch,
I love the gums and the magpie will always be my fav Aussie bird, looking forward to your next vid, the work you put into them is really appreciated
🙂👍
Mate, your videos are first rate and I’ve just watched all three - please make lots more!
Mate as an Aussie botanist, this is a great video and well researched. You described it all pretty accurately, well done 👌
Wow so enjoyed this video, how you put it all together is wonderful. So informative, so visually appealing. Thank you
Just got recommended one vid and had to watch them all. (Didn’t take long) and your hilarious keep it up!!
I love your videos and watched the magpie episode more than twice. I know I will watch the magpie one and this one more because I really enjoy them. Your speech is perfect. I am wondering whether you could slow down the pictures motion and make your EIGHT minutes video program into around TWELVE minutes, same content, just slow down. ❤your videos and longing for more.
didnt expect this hard of a video from a channel about plants, banger vid.
This is great! Hi from Melbourne, im absolutely loving your videos, thanks!
I’m loving these videos! please make one about paper bark trees I’ve been very much enjoying them lately!
Fantastic video. You just earned yourself another subscriber. Looking forward to seeing your next ones.
I look forward to your continued career on youtube mate. Keep up the great work!
