A group of curious scientists set out to research whether trees sleep. They spent several nights tracking changes in a birch tree using infrared laser scanners. They discovered that the birch tree they were studying drooped its branches by an average of 10 centimeters at night. Once daylight hit, they lifted back into place. Scientists know that trees cycle through different physiological changes depending on certain factors, like water balance and light availability. But why branches relax is still a mystery. Is it to conserve energy overnight? Is it because of too much or too little water? Is it the lack of light? What we do know is that trees may not sleep in the traditional sense, but they do take time to unwind. Considering how hard they work for us and the planet during the day, they’ve certainly earned the rest.

We know that most Americans want to live in neighborhoods with more trees, yet only a minority have planted a tree in the past year. We are going to help you become a tree planter without ever having planted a tree. By becoming an Arbor Day Foundation member, you’ll receive 10 trees to plant in your neighborhood while helping support tree plantings in forests and communities around the world. As a member, you’ll gain the confidence to plant trees successfully and enable us to show up when and where we’re needed and plant at the speed and scale necessary to strengthen communities and revive our planet’s most important forests. You can also opt to send your 10 trees to a forest where they’ll make an impact. Whatever you choose to do, you will be there, right alongside us, planting for future generations. No shovel, no gloves, no backyard needed.

From a heavily used industrial rail yard to a vibrant waterfront park. To kick off Climate Week NYC, @verizon joined us to plant some of the final trees at Riverside Park South, helping to complete the transformation of this once-industrial site. In a city shaped by what people build, trees help create something essential, too: greener, healthier and more resilient communities.

What does it take to protect a spring that produces more than 500 million gallons of clean water every day? At Indian Lakes State Forest in central Florida, restoring longleaf pine forest is part of the answer. In 2016, 40,000 trees were planted across this 4,400-acre property, helping restore former fields and pastureland and protect groundwater recharge areas that feed Silver Springs — one of the largest artesian spring formations in the world and a National Natural Landmark. As the forest grows, it will help support water flow and water quality while creating habitat for Florida black bears, white-tailed deer, wild turkey and countless other species. A forest can do more than grow trees. It can help protect the water we all depend on.

Aspen trees can have an incredible root system that spreads underground with new trunks emerging to make a forest. When aspen trunks grow from the same root system, they are clones that sync up, dropping leaves, changing colors, and leafing out all at the same time. Through their connected roots, they can even share nutrients and alert each other of insect attacks. And when individual trunks die, the root system lives on, sometimes for thousands of years, sending up new trees to take their place. A good reminder that nothing in nature stands alone.

A hollow tree might look like a small feature of the forest or neighborhood, but inside, it can create a surprisingly stable environment for wildlife.​ A new global analysis looked at 36 studies spanning five continents and found that tree cavities consistently buffered temperatures from the conditions outside. The effect was influenced by things like cavity depth, opening size and the size of the tree — meaning the structure of the tree itself can shape the climate available to the animals living inside it.​ That matters as animals face more frequent and intense temperature extremes. A cavity isn't just an empty space in a tree. It can be nesting habitat, shelter and a place where wildlife can escape conditions that would otherwise be dangerous.​ Want to learn more of what the researchers discovered?

Every fall, trees put on a spectacular color show that happens inside their leaves. In the summer, leaves are packed with chlorophyll, which helps them turn sunlight into energy. As the days get shorter and the nights get longer, chlorophyll production slowly stops, allowing existing pigments to shine through, like yellows and oranges. A new pigment called anthocyanin forms when sugars are trapped in leaves. Anthocyanin may also protect leaves from sun damage, helping trees draw more nutrients from the leaves before they drop. It's the eye-catching reds, purples, and crimsons we love to see. Even though there's a very scientific explanation of the leaves changing, we get to enjoy the magical show.

Every bottle of bourbon has a story that starts long before the barrel. And at the heart of that story is American White Oak. But there’s one catch: White Oak takes decades to grow.​ That’s why @angelsenvy's Toast the Trees program is about more than planting trees today. It’s a 70-year investment in the future of bourbon — helping replenish the White Oak forests that this storied industry depends on for generations to come.​ It’s a full-circle partnership: giving back to the forests that give so much to bourbon, while helping create a healthier environment for generations to come. Here’s to the trees behind the barrel and to the future they’re helping grow.​

At Mehraban Wetlands Park in Draper, Utah, 30 native trees are helping strengthen an important wetland habitat.​ Planted along wetland edges and trails, these trees will provide shade for park visitors, support pollinators and create new layers of habitat for wildlife. Their roots can also help improve water quality by helping filter and slow runoff before it reaches the wetland.​ And with 554 people indirectly impacted, this is a reminder that when we plant trees in shared spaces, the benefits can spread far beyond the planting site.​

This month, I joined urban forestry leaders from across Australia at the 27th Annual TREENET Street Tree Symposium, hosted by @nationalurbanforest in Adelaide.   From addressing extreme heat to helping communities better understand the value of trees, cities around the world are navigating many of the same challenges. When we share what’s working and learn from one another, local ideas can lead to global progress.   Through programs like Tree Cities of the World, we’re proud to help connect and celebrate the people building greener, more resilient communities worldwide.
