Arbor Day is a time to encourage people to plant and protect trees. Many communities traditionally take the opportunity to organize tree-planting and litter-collecting events on or around the holiday. The first modern Arbor Day dates all the way back to 1805. The first Arbor Day in the United States was held in 1872 when an estimated one million trees were planted in Nebraska. Trees provide the very necessities of life itself. They clean our air, protect our drinking water, create healthy communities, and feed the human soul. But these life necessities are threatened around the globe.
Arbor Day Foundation: The Time for Trees
Trees are an important part of the solution to many critical issues facing the planet. Trees purify our air, filter our water, and cool the earth. But our trees are at risk.
The Arbor Day Foundation has launched an initiative — Time for Trees — to plant trees at an unprecedented scale: they want to plant 100 million trees and engage five million tree planters by 2022. With their networks of members and partners, as well as access to both public and private land for tree planting, they are uniquely positioned to lead this undertaking.
Arbor Day 2021: What and When is Arbor Day?
Arbor Day is always observed on the last Friday in April. This year, it’s Friday, April 30, 2021. Arbor Day is a national holiday created to recognize the importance of trees. The most common way people celebrate Arbor Day is to get together in groups to plant trees.
The day was the brainchild of Julius Sterling Morton, a Nebraskan journalist who later became the U.S. Agriculture Secretary under President Grover Cleveland. Morton was an enthusiastic promoter of tree planting, had long championed the idea of a day dedicated to planting trees. Learn more about Arbor Day from the Farmers’ Almanac.
Learn Why We Celebrate Arbor Day and Plant a Tree!
Arbor Day is celebrated on the last Friday in April, although some states observe it on dates that better coincide with the local area’s planting times. For instance, Hawaii celebrates Arbor Day on the first Friday of November, and Alaskans celebrate it on the third Monday in May. Find out when your state observes Arbor Day.
Arbor Day is meant to encourage people to plant trees, and many communities traditionally take the opportunity to organize tree-planting and litter-collecting events on or around the holiday. A popular Arbor Day tradition is to plant a tree in honor or memory of a loved one. Dedicate a tree to someone who is special to you, and check out these facts about Arbor Day and the man who founded it from the Old Farmer’s Almanac.
The History of Arbor Day
Arbor Day — which literally translates to “tree” day from the Latin origin of the word arbor—is a holiday that celebrates the planting, upkeep and preservation of trees. For centuries, communities spanning the globe have found various ways to honor nature and the environment.
However, the appreciation of trees and forests in modern times can be largely attributed to Arbor Day. And although Arbor Day may not have the same clout as holidays like Valentine’s Day or St. Patrick’s Day (or even Earth Day), it has a history with strong roots that branched out across multiple nations. Arbor Day 2021 will occur on Friday, April 30, and is typically celebrated on the last Friday in April in the United States. Learn more about Arbor Day from the History Channel.
The Power of One Tree - The Very Air We Breathe
Just as we humans are comprised of many parts functioning together allowing us to do wondrous things, the anatomy of a tree is just as wondrous, empowering them with super hero qualities. A tree has the ability to provide an essential of life for all living things on our planet – oxygen, and the power to remove harmful gases like carbon dioxide making the air we breathe healthier.
Here is how it works. A tree is comprised of its leaves, stems, trunk and its roots. When you look at a tree, note that about five percent of the tree is comprised of its leaves, 15 percent its stems, 60 percent goes into its trunk and 20 percent is devoted to its roots. Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree. It is proposed that one large tree can provide a day’s supply of oxygen for up to four people.

The Importance of Forests
The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the water we drink. Forests provide habitats for animals and livelihoods for humans, prevent soil erosion and mitigate climate change. But deforestation rates across the planet are putting our forests under threat. From the bushfires in Australia to the slow destruction of the Amazon forest. Now more than ever, the world's forests need our attention.

Wild For Life Journeys – Forests
Nature sustains all life on earth, but nature is under threat. One million wild plant and animal species are facing extinction – many within decades. Three-quarters of the land-based environment, eighty-five per cent of wetlands, and two-thirds of oceans have been significantly and negatively altered by human activity.
The UN Environment Programme has created immersive digital experiences for its #WildforLife campaign. These four ecosystem-based “journeys” show the magic of interconnected natural systems and inspire people to take action to protect these distinct ecosystems.
What Would Happen If We All Helped Plant Trees?
Large scale global ecosystem restoration and reforestation is possible and can be done when millions of people contribute to tree planting. The Trillion Trees Campaign offers a simple way to get involved by helping to plant trees for as little as 10 cents per tree – micro-crowd funding our way to a thriving future. Visit http://www.trilliontreescampaign.org to learn more.
How Trees Clean the Air
Trees and forests are constantly cleaning our air and improving our air quality. They exhale the oxygen we need to breathe, while absorbing carbon dioxide and other air pollution. Here are four things that trees do for our atmosphere that are essential for our health and our quality of life: trees create oxygen; trees reduce air pollution; trees remove humid hazes air; and Trees Prevent Dust Storms.

Jane Goodall on the Importance of Planting Trees
Jane Goodall started her career studying chimps in Gombe, Tanzania. Her work changed the way we see chimps forever, but when she returned to Gombe 30 years after her first visit, she was shocked to see it had been stripped of most of its trees — an island of forest surrounded by completely bare hills, with people struggling to survive.
Thanks to Goodall’s innovative Roots & Shoots program, thousands of kids around the world are planting trees, encouraging children to volunteer in nature. Now, Goodall’s taking her reforesting mission to the next level, joining the global movement to plant and protect one trillion trees.
The Canopy Project
The Canopy Project improves our shared environment by planting trees across the globe. Since 2010, earthday.org has planted tens of millions of trees with The Canopy Project, working worldwide to strengthen communities.
Earthday.org works with global partners to reforest areas in dire need of rehabilitation, including areas with some of the world’s communities most at-risk from climate change and environmental degradation. They have also conducted broad tree planting in the wake of environmental disasters.
What if Everyone Planted a Tree?
Around 30 percent of our planet is covered in trees — that's approximately three trillion trees, according to this video from BBC Ideas. As well as helping with biodiversity, they can also help combat climate change. But we're cutting our trees down at an alarming rate — 4.1 million a day. So, what would happen if everyone on the planet — all 7.7 billion of us — planted a tree?
What Are Urban Forests?
Over 141 million acres of America’s forests are located right in our cities and towns. Urban forests come in many different shapes and sizes. They include urban parks, street trees, landscaped boulevards, gardens, river and coastal promenades, greenways, river corridors, wetlands, nature preserves, shelter belts of trees, and working trees at former industrial sites. Urban forests, through planned connections of green spaces, form the green infrastructure on which communities depend. Green infrastructure works at multiple scales from the neighborhood to the metro area to the regional landscape. Learn more from the U.S. Forest Service.

Spotted Lanternfly Basics from iEcoLab
According to the Pennsylvania Department of Agriculture, the Spotted Lanternfly is an invasive species native to China, Bangladesh, and Vietnam. In 2014 it was found in Pennsylvania, and has since spread to 26 counties which are now quarantined. If you see a Spotted Lanternfly, it's imperative to immediately report it online or via phone by calling 1-888-4BADFLY. This pest poses a significant threat to the state’s more than $28 million grape, $87 million apple, and more than $19 million peach industries, as well as the hardwood industry in Pennsylvania, which accounts for nearly $17 billion in sales.
Viral Water Bottle Hack for Trapping Spotted Lanternfly
The Pennsylvania Department of Agriculture is not subtle about what you should do if you see a spotted lanternfly — "Kill it! Squash it! Smash it! Just get rid of it!" You get the idea. iEcoLab in Temple’s Department of Biology, however, has tested out the viral hack of catching spotted lanternfly (SLF) with an empty water bottle that requires a lot less messy squishing. SLF bottle trapping can be a safe and easy method to euthanize the pests humanely and sustainably.
Get a bottle.
Trap the hoppin' SLF.
Freeze the bottled SLF.
Compost the caught SLF.
Reduce, reuse, recycle bottles.
