Spending #ArborDay on the air in the media capital of the world. Loved spending the day with @ABCNewsLive and @WNYC talking about the power of trees.

Happy Arbor Day, and thanks to these journalists for helping spread the message when it matters most.

We teamed up with @Snoopy to light the @EmpireStateBldg green for Earth Day.

Grateful to be part of a movement that continues to grow, reach higher, and shine brighter every year. 🌎🌳

Big morning talking trees on the @weatherchannel 🌳

Loved being back on air with @JimCantore and @StephanieAbrams (and of course, seeing @JordanSteele) to talk about Arbor Day and how trees help cool communities.

Can't thank this crew enough for supporting the work we do!

An inspiring week in SoCal, surrounded by partners leading the way in recovery and replanting efforts after the Eaton Fire.

We are grateful to work alongside such dedicated, passionate collaborators. Together, we’ll continue to bring back life, shade, and hope to this region.

What if connection could change the way you see the world?

In Unearthing Optimism, Anna Rathmann reflects on how studying chimpanzees opened Dr. Jane Goodall's eyes not just to animals, but to the deeper truth of our shared world.

Listen to this new episode of Unearthing Optimism wherever you get your podcasts.

Please note: This conversation was recorded prior to Dr. Goodall’s passing. We dedicate this episode to her — her life, her work, and the enduring hope she gave the world.

One year after the Eaton & Palisades Fires, the scars remain in LA County, but so does hope.

At an Altadena-area school in the burn zone, we planted trees with @amigosrios and generous partners to help restore a space for students.

[Dan Lambe @DanLambe]

California, you delivered.​

An inspiring visit seeing forest sustainability and urban tree management in action. From @longbeachcity to @TaylorGuitars, I'm grateful for the partners and leaders using trees to make a real difference for people and communities.

Wrapping up a week of meetings in Mexico with partners as we grow the Tree Cities of the World program. Mexico City is as special as everyone says it is. Great parks, people, food and even a birthday surprise. Thank you @ReforestamosMx for your fantastic partnership! 🇲🇽 🇺🇸🌳🌲🌎

[Dan Lambe @DanLambe]

Happy #ArborDay! The @NYSE wanted trees and the @arborday team to take center stage at its iconic opening bell ceremony. What a way to celebrate this important day.

[Dan Lambe @DanLambe]

Now more than ever, trees are vital to our planet. Not only do trees provide beauty and relaxation, but they also make areas more sustainable and resilient. Thank you to the @weatherchannel with @JimCantore and @StephMcMahon for speaking with me about our pledge.

[Arbor Day Foundation @arborday]

This is a turning point for the planet. Experts agree a colossal amount of trees need to be planted.

The future will take all of us doing whatever we can. It’s why we’re evolving our brand to bring everyone in on the same team to plant a better world. Including you.

[Dan Lambe @DanLambe]

It’s more than a new look. It’s a renewed commitment to being bold enough to shape a better future, together.

Beyond proud of our team at @arborday for meeting the moment.

[Arbor Day Foundation @arborday]

Hope for the planet is bold. But at the Arbor Day Foundation, we hear a better future calling. For more than 50 years, we’ve inspired people to plant, nurture, and celebrate trees. But to plant at the speed we need to change the world, we have to grow to meet this moment.

That’s why we’re evolving our brand. To connect our vibrant network of thinkers, doers, organizers, leaders, supporters, and planters with one another, and with a better future. By teaming up with us, we’re making it clear that each of us are part of the same living, growing movement.

It’s more than a new look. It’s a renewed commitment to being bold enough to shape a better future, together. When progress feels impossible, with support or shovels, you can make a greener world happen.

[Dan Lambe @DanLambe]

In this moment when the future health of the planet can feel uncertain, we need to be bold enough to believe in better days ahead. To put hope in motion by doing the work our world needs from us.

That’s why our global nonprofit is evolving its brand.

10million trees!

[Arbor Day Foundation @arborday]

Within 2 weeks, Hurricanes Helene and Milton ripped through cities, towns, and homes. Countless stories of hope, kindness, unity, and compassion have emerged following the storms, showcasing the incredible resiliency of humanity.

It’s a reminder that even on our darkest days, we can be bold enough to believe in better days ahead.

That’s why we're pledging 10 million trees to help communities and forestlands across the six states impacted by Hurricanes Helene and Milton.
