We did patrols around Harcourt the day after the fire came through & hosed down old trees along the roadsides that were still burning. Terrible to see the loss. And that was before they did 'clean up' for safety. The cumulative loss of old trees is hard to bear.

A magnificent River Red Gum (Eucalyptus camaldulensis), photographed in Harcourt by Alan Deumer. Sadly, it burned to the ground in recent fires. For centuries it sheltered wildlife and watched over the community. Farewell, stately giant. 📸 Alan Deumer #thicktrunktuesday

Hey nature lovers! #NationalEucalyptDay2026 is just over the horizon and we can't wait to celebrate with you! This year it is all about Our Eucalypt Home 🏡 Fancy hosting an event? Get involved here: eucalyptaustralia.org.au/host-an-event/

A week on from the heatwave and catastrophic fires here in Central Victoria. We're taking a moment to enjoy the cool breeze amongst the scented blossoms of a Yellow Box (Eucalyptus melliodora). It's such an intensely different day from this time last week. #FlowersOnFriday

We’re thinking of the communities, wildlife, and places affected by the recent bushfires. We recognise and share in the deep grief many feel for the loss of homes, businesses, stock and pets, and the beloved trees and bushland people love. Our thoughts are with everyone impacted. ❤️

Congratulations & thank you to 2025 Dahl Fellow Peter McHugh as he wraps up his fellowship project, “The Working Forests” – a free two-volume eBook recounting the story of Victoria’s State Forests from the 1800s to the present. Vol.1 nla.gov.au/nla.obj-4135... Vol.2 nla.gov.au/nla.obj-4135...

Two stunning, haunting scenes this #ThickTrunkTuesday by Joy Kachina Photography. Joy captures the dying Miena Cider Gums of Tasmania—majestic even in decay. Endemic, endangered, and vanishing fast due to climate change. Read more about this project: www.joykachina.com.au/miena-gums-p...

Happy #ThickTrunkTuesday from Gariwerd/The Grampians, where Will Hudson captured this ancient Red Gum stag. "Hidden away down a quiet Grampians road, this Eucalyptus camaldulensis hosts three scars, striking remnants of history & culture of past centuries. An honest time traveller across our lands"

Happy #ThickTrunkTuesday, everybody. This gorgeous big River Red Gum (Eucalyptus camaldulensis) shrouded in mist was photographed by @treeside.bsky.social‬ near Mount Pleasant, South Australia. Show us your big gums! Tag @eucalyptaus to feature on a future #ThickTrunkTuesday!

Microgrants for #NationalEucalyptDay2026 are open! The theme is "Our Eucalypt Home"—we're seeking events that celebrate gums + Aussie flora & fauna. Info + EOI: eucalyptaustralia.org.au/national-euc...

Happy #ThickTrunkTuesday from the Eucalypt Lawn at @anbgalive! With 70+ eucalypt species, it’s a top spot for #EucalyptID—or just resting in the shade from Angophora, Corymbia & Eucalyptus. Tag @eucalyptaus in your pics for your chance to be featured #LoveAGum #eucbeaut 🌳

Last week we shared the green gumblossom of Eucalyptus platypus—but is it named after the Platypus? Not quite! Both names come from Greek: platy = flat, pus = foot. The tree has flat flower stalks; the animal, flat feet. Same roots, different species! #LoveAGum 📸: Dean Nicolle

🌿 Planning has begun for #NationalEucalyptDay2026! 🌿 Theme: Our Eucalypt Home We're calling for events that celebrate the biodiversity value of eucalypts — in bushland, farms, towns + suburbs. Info + EOIs now live: eucalyptaustralia.org.au/national-euc... #LoveAGum #OurEucalyptHome #ozplants

Happy #ThickTrunkTuesday, everyone! Old Blotchy is the second largest Spotted Gum (Corymbia maculata) in the world, at 58 metres tall and 10.7 metres in circumference. #LoveAGum 📸: helenwylkscross on Instagram

Let’s hear it for the big old habitat trees this #ThickTrunkTuesday! Dead or alive, they’re vital for wildlife. Show us your local legends—tag #LoveAGum + #ThickTrunkTuesday and shout out the landowners and councils protecting them! 🌳: Yellow Gum (Eucalyptus leucoxylon)

Two Fuchsia Gums often confused: Eucalyptus dolichorhyncha & E. forrestiana. 🌺 Look to the bud cap (operculum): dolichorhyncha has a long, pointed “nose” (from Greek dolicho = long, rhynchos = nose); forrestiana has a rounded dome. #LoveAGum #eucalyptID

Happy #ThickTrunkTuesday, tree friends! This beauty is a Yellow Box (Eucalyptus melliodora) from near Beechworth, Victoria. Sound on for the calls of Pied Butcherbirds! #LoveAGum #treeoftheday #australiannature #bigtree #eucalyptusmelliodora

#FlowersOnFriday: Lemon-scented Gums aren’t just about that iconic citrus scent 🌿—they explode with nectar-rich white flowers that lure birds, bees, bats, gliders, moths & more. A generalist pollinator magnet, spreading pollen far & wide! #LoveAGum 🌳: Corymbia citriodora

🌱 #DidYouKnow most eucalypts can thrive in pots? Choose the right species, use free-draining native mix, give them sun + shelter, and don’t overwater. Airpots help avoid root issues, and pruning keeps them in shape. More tips + inspo on our Instagram and Facebook 👇 #LoveAGum #pottedeucs #ozplants
