Botanist here. 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.

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.
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!
California gave Australia Monterrey pine or Pinus radiata and Monterey cyprus, or cyprus leyandii as the weather in South eastern Australia is similar to California. The SEPO Trees give us Aussies a headache just as the eucalypts give them one. Sorry about the spelling but it is late.
@paulphotios3920 by the way since Australia gave california eucalyptus trees california has been in flames ever since because they are not supposed to be in california only Australia is built different for those types of trees
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 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!
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!
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 🤕
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.
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!
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
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 😊
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.
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.
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!
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.....
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!
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.
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. 💜❤️👍🏼
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.
? 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
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!
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.
Bro you need mroe subscribers! Really dotn stop making contents i look fowarrd to your videos the humor + the editing and the accurate knowledge! Please keep it up
Absolutely fascinating. Thank you. I live in Portugal where many eucalyptus grow in these northern mountains. They are truly beautiful and I now admire them even more after watching this.
Many years ago heading to Lisbon I was amazed descending the plateau from Spain to see eucalypt forests outside the train window. I had to look twice and shake my head, it was so familiar. Along Californian freeways too.
@@emceeboogieboots1608 - Australian eucalypts were widely distributed in the 19thC because they were thought of as a hardy dry land tree. When in fact they just have a long tap root that searches down for the water table, which is a problem in many places now. There’s even hybrid species unknown in Australia, one at least in Brazil.
@TenOrbital That is very true for some. Many though are drought resistant. Inland western Australia particularly has no water table to speak of, and is often saline where it exists. These trees are not likely to be widespread overseas though I imagine
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.
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.
