TREES
"I am the Lorax. I speak for the trees, for the trees have no tongues." — Dr. Seuss
Our Hill Country trees, such treasures
|
By Frank Dietz Herald-Zeitung January 30, 2021 In surveying my own life journey through the decades, it is clear that a very early fascination with and appreciation for trees developed. My earliest connection remains a cluster of Gulf coastal oaks. They provided playscapes and meditation that nurtured my spirit and imagination. Perhaps you have a similar special place you go to in your personal memory bank. As our childhood habitat expanded it grew to include two historic public parks in uptown New Orleans where play and inquisitive discovery were nearly endless. Later in life as visitors, our children and grandchildren have had their turns at developing adventurous explorations and memories among moss draped live oaks. The valuing of trees that was rooted in my early life experiences has prompted attention at every turn to the gifts of trees in our contexts for living and exploring. One dramatic moment comes to mind when our older son came home from his nearby high school on lunch break. A creek bed that wound around our home was being deepened and widened for drainage purposes in an overdeveloped area. A huge handsome sycamore was marked for removal. Lunch break was over and I approached inquiring about whether our son had lost track of time. Alas, I found tears! His fist came down on the table as he declared he wasn’t returning to school but “going out there to climb that tree so they can’t destroy it and cut it into pieces!” Oh, my! Before he could be calmed it took some reasoning and work with my own feelings about engineering and political plans with little or no regard to grand trees and their value. Fast forward to note a personal support of our late life domicile in an oak motte in Comal County. |
Yes, it presents some constant challenges and demands but mostly provides shade, pleasure and a fascinating habitat for the winged and wild neighbors we know currently in greater intimacy with 2020-2021 quarantine life. It is my great personal physical, emotional and spiritual good fortune to twice or more each day go on our lane through two wooded strips between our “haus” and the county road where mail, papers, packages and more are delivered.
When I need a break a bench, hammock or convenient low branch offers a place to reflect and restore. Along the ranch’s creeks is an array of life in abundance. Heritage oaks send the imagination into soaring zones of reflection and quieting. What a gift of our Hill Country life! We can drive in any direction here in Comal and neighboring counties to see the implications of being a top growth community in the USA. Even more telling is any drive on our interstate corridors (I-35 and I-10) or other major thoroughfares where so many acres are being opened for development. Too frequently one notes that Hill Country trees to be removed to expand access and improve mobility with little or no thought for mitigation. Indeed, just like our son had to understand that flood control measures when well planned serve an important purpose, so, too, pathways for transit can be important. One just hopes the planning is “smart” and cognizant that grand Hill Country trees do not grow in a few days but require decades. As so much acreage is repurposed for home sites and supporting services in the Hill Country, we have to plead for diligent responsible planning. Some of that begs for setting aside parcels of value to future generations. A growing number of neighbors and colleagues share commitment and passion about Comal’s land, water and wildlife. They make for wonderful new friends and collaborators. Join the conversation about our Comal County Hill Country stewardship as we go forward at ComalConservation.org. It’s a worthy conversation with much discovery ahead! |
San Antonio now must report tree variances

Jan. 29, 2021Updated: Jan. 30, 2021 4:22 p.m. For at least two years, the San Antonio city development office has routinely given developers every variance they wanted to skirt the tree preservation ordinance, letting them remove thousands of trees without the knowledge of the city’s elected leaders. Now that’s going to change. Reacting to an investigative report in the San Antonio Express-News, City Manager Erik Walsh has directed staff to be more transparent about any variances to the ordinance given to developers. In an email to Walsh and the City Council on Tuesday, Mike Shannon, director of the city’s Development Services Department, promised to track and share all variances to tree preservation rules that are requested and approved, as well as any fines assessed or waived by the city, and any requests for exceptions to the ordinance made by elected officials. “I believe this strengthened reporting and documentation will allow us to review our process related to these variances and allow us to make any necessary changes or adjustments if we identify issues in terms of appropriate application and consistency,” Shannon wrote. The city decided to change the policy after the newspaper found that developers asked for 206 variances to the tree ordinance in the last two years and that all were granted. The report also revealed how state Sen. Roland Gutierrez, D-San Antonio, persuaded |
Shannon to waive a $2,000 fee he was assessed for cutting down a large heritage oak tree without a permit. Shannon now must send Walsh a monthly summary of any variances and fines. And if an elected official requests an exception to the tree ordinance, Shannon must alert the city manager “immediately,” Walsh said. “I think it improves awareness,” Walsh said. “And if we start to see trends or issues that have to be addressed, then there’s a heightened awareness about it. But that aside, the tree ordinance is hugely important and has been the source of a lot of debate in this city for a long time. I think that regular report that we can make available and that I can view is important from a management standpoint.” Walsh said the impact of the 206 variances was minimal, noting they represented a “very small portion” of the total tree permits — about 10,600 — issued by Development Services in the last two years. “It’s a very small portion of the total number of permits that are issued, and so I’m not concerned with that,” Walsh said. “I think everybody’s intention is to live within the tree ordinance and the regulations, and I think the development community does that and I think we administer it that way.” Read more at: www.expressnews.com/news/local/politics/article/San-Antonio-now-must-report-tree-variances-15908382.php?utm_source=newsletter&utm_medium=email&utm_campaign=SAEN_210Report&utm_term=news&utm_content=headlines&sid=5b02346b24c17c5e3d90593a |

Jan. 21, 2021Updated: Jan. 22, 2021 4:21 p.m. In 2019, a city environmental plans examiner emailed then-state Rep. Roland Gutierrez to inform him he had violated San Antonio’s tree preservation ordinance by chopping down a large heritage oak without a permit on a lot he was developing. “There will be a work without permit penalty of $2,000 assessed to your project,” Robin Loyd wrote to Gutierrez, D-San Antonio. The fine didn’t stick. Upset by the penalty, the state lawmaker called Michael Shannon, director of the city’s Development Services Department, to protest. Shannon then instructed staff to waive the fine. Shannon’s decision caused an immediate rift inside the department. But the bending of tree rules already was business as usual at the city, where developers often ask staff for exceptions to the tree ordinance — and almost always are successful, an investigation by the San Antonio Express-News found. In the last two years, even as population growth continued to explode in San Antonio — the city ranked second in the nation after adding more than 17,000 people between July 2018 and July 2019 — developers asked for 206 exceptions to the tree ordinance. All were granted. City of San Antonio Development Services tree inspector Robert Kwiatkowski examines trees in the Davis Ranch Development near the Government Canyon State Natural Area. Each lot is to have four trees of a certain size. |
In theory, the city’s tree ordinance is designed to protect all heritage trees — large, old-growth trees of 24 inches in diameter or greater — and 35 percent of “significant” trees on a property. Developers who remove more than that must mitigate the loss by paying fees or planting new trees that eventually would provide tree cover of at least 38 percent on the property. A 2010 revision to the ordinance reduced the amount of trees that developers can remove and mitigate on a property from 90 to 80 percent. But the city’s development code allows them to request exceptions to this rule. In floodplains or environmentally sensitive areas, where the ordinance requires the preservation of 80 percent of all trees, variances must be approved by the city’s Planning Commission. Otherwise, city staff can grant the exceptions. Shannon, who was appointed director of Development Services in 2017, said all requests are considered on a case-by-case basis. Any exceptions must be justified by “hardships” facing the developer, he said. “No matter how many codes we write, there’s always going to be circumstances with some hardships where alternatives or variances are warranted,” Shannon said. “The whole goal is even if you don’t meet the black and white letter of the code, you meet the intent of the code. The intent of the code is what we have to protect at all costs.” In some cases, staff approved exceptions simply because developers found it difficult to develop a site without removing more trees, the newspaper’s review of city records found.

HERITAGE TREES
The beautiful Founder's Oak in Landa Park is over 150 years old.
|
By Rosemarie L. Gregory and Arlene K. Seales
Herald-Zeitung January 23, 2021 Landa Park, New Braunfels was chosen as the site for the 1998 State of Texas Arbor Day Celebration. Associate Director of the Texas Forest Service Tom Boggers stated, “It’s important to select a community that is setting the standard for caring about their community through the care and nurturing of their urban forests.” New Braunfels met those criteria. The year 1998 marked the community’s 10th year as a Tree City USA, a distinction awarded by the National Arbor Day Foundation and the Texas Forest Service to recognize cities who made environmental improvements and encouraged tree care. New Braunfels also received the Texas Urban Forestry Council’s Award. The community was noted for the fine examples of cooperation demonstrated between the City and the Garden Clubs with special emphasis on the trees, their planting, and the necessity of good care. Dignitaries came to Landa Park to join with local residents in the observance of Texas 109th Arbor Day to celebrate the magnificence and utility of trees. There was much time spent in preparing for this grand occasion that New Braunfels was co-sponsoring with the Texas Forest Service, Texas Forestry Association, and the Texas Association of Nurserymen, Inc. A planning meeting was held on February 10 at the New Braunfels Municipal Building on Castell Street, with Tom Boggers who came from College Station. Others attending were City Manager Mike Shands; Parks Director Iris Neffendorf; County Extension Agent Marty Gibbs; New Braunfels High School Principal John Thurman; District VII Director Barbara Perry; San Antonio Urban Forester Mark Peterson; Men’s Garden Club of New Braunfels President Kenneth Triesch; Comal Garden Club President Laura Behrendt; Four Seasons Garden Club President Ginger Abbott; New Braunfels Garden Club member Marie Offerman; Guada Coma Garden Club representative Dolores Schumann; Four Seasons Garden Club members Sue McFeeley and Nancy Schultz; and Ferdinand Lindheimer Chapter President, Daughters of the Republic of Texas, Delitha Guenzel. By mid-March, Parks Director Iris Neffendorf had all the invitations to the event mailed. In addition, she had the Park Rangers from her department make presentations on the importance of trees and Arbor Day to over 500 students in the Comal and New Braunfels Independent School Districts. The Parks Department also promoted poster and poetry contests with the winners to be honored at the Arbor Day Celebration in Landa Park. Theme of each contest was, “The Benefits Trees Provide.” Comal Garden Club sponsored the Oak Run sixth-grade poster contest with the winning posters: First place: Tiago Hillermann, Second place: Kelley Shelton. Poetry contest winners were Brittany Stanford and Aaron Coronado. The Carl Schurz School contest was sponsored by the Men’s Garden Club of New Braunfels. The First place winner was Ashley Romo, the Second place winner was Karen Zentiek, Third place winner was Amanda Saenz, and the Fourth place winner was Patrick Mills. |
On Friday, April 24, 1998, crowds of people, local residents and statewide dignitaries, arrived at Landa Park to celebrate the beauty and resources of trees during the observance of Texas’ 109th Arbor Day. “We’re here to honor people and the relationship people have with
trees…and the quality of life that comes about because of this relationship,” said Jim Hull, director of the Texas Forest Service who served as master of ceremonies. Mayor Pro-Tem of New Braunfels Ray Schoch welcomed all to Landa Park in New Braunfels to celebrate the 109th Texas Arbor Day. The Invocation was given by Dr. Kenneth Peters of New Braunfels Presbyterian Church. The Presentation of Colors and Pledge of Allegiance were provided by the New Braunfels High School Marine Corps Jr. ROTC Color Guard. Mayor Pro-Tem Schoch then presented the Arbor Day Proclamation by the City of New Braunfels. James P. Hull read the Governor’s Proclamation. The ceremonies included musical presentations by the New Braunfels High School Choir under the direction of Judy Bagley, the Comal County 4H, and “Trees for America” sung by City Council member Cathy Talcott. Seele fifth grade students recited “Trees of the Fragrant Forest.” During his address, featured speaker State Senator Jeff Wentworth, urged everyone to plant new trees for future generations, “Trees are a source of joy for spiritual renewal,” he stated. Trees serve many purposes in the ecosystem as windbreak enhancement, reducers of soil erosion, and suppliers of oxygen. In addition, trees increase property values, beautify the community, and promote the well-being of all citizens, today and tomorrow. As part of the ceremony, New Braunfels Garden Club donated a Texas Red Oak tree that was planted in recognition of the 109th Arbor Day Celebration in Texas and the 65th Anniversary of the New Braunfels Garden Club. Other trees planted were donated by MeSuJo Services, Ferdinand Lindheimer Chapter, Daughters of the Republic of Texas; Christine Brown in memory of Dr. Dorris Brown; and Four Seasons, Comal, and Guada Coma Garden Clubs. Landa Park served as an ideal setting for the State Arbor Day celebration with over 70 species of trees including the 300-year-old Founders’ Oak in its Arboretum. In addition to the Arboretum there were the enormous ancient Cypress along the Mill Race. In the 1850’s these water-loving Cypress were the signal to William Hunter Meriwether that a former channel of the Comal River flowed there enabling Meriwether to support his mills. This column is based on the book New Braunfels’ Historic Landa Park, Its Springs and Its People by Rosemarie Leissner Gregory and Arlene Krueger Seales.

History rich in trees
|
By Jane W. Miller
Friends for the Preservation of Historic Landa Park Herald-Zeitung Feb 6, 2021 The William and Dolores Schumann Arboretum Guide, which is offered in the Parks Office and online (www.nbtexas.org/DocumentCenter), describes some of the over 80 species of trees in Landa Park. There is an allure of history and charm documented in those pages. Entry No. 1 is the Ginkgo (Ginkgo bilboa). The Ginkgo can be found outside the Parks Office on Golf Course Drive. It’s on the left side of the sidewalk entrance. Ginkgo, you ask; is that a native tree? The answer is no. Ginkgo is native to China, where it has been used in Chinese herbals for a long, long time. Also called the Maidenhair tree, Ginkgo is the only living species in the botanical division Ginkgophyta. All others are extinct. Gingko tree fossils which date over 200 million years have been found. In North America, the Ginkgo Petrified Forest State Park along the Columbia River and southeast of Yakima, Washington, was founded in the 1930s because petrified wood was discovered near the Columbia River. Over 50 species of petrified wood, including Ginkgo, were found. Today, the conservation status of Ginkgo bilboa is “threatened” yet we in New Braunfels have a living example right outside the Parks Office. Notice it and show your children. The history of Founders’ Oak is more widely known. This beloved Texas live oak (Quercus fusiformis), entry No. 11 in the Arboretum Guide, joined a select group in 2012 when the Texas Forest Service declared Founders’ Oak a “Famous Tree of Texas”. Our famous oak became the 87th member of what former San Antonio Express-News writer Zeke MacCormack described as “an elite arboreal club.” In documents submitted by the city’s then urban forester, Kelly Eby, we learn that Founders’ Oak, which is over 300 years old, was witness to:
|
Ferdinand Lindheimer documented cypress trees with a diameter of 3 to 7 feet along Central Texas rivers. Lindheimer further reported:
“Not all kinds of wood split into shingles in the same way. Some species split better with the growth rings (concentrically), some better across the growth rings (diametrically). Oak species in particular belong to the latter, coniferous species to the former, but above all of them is the bald cypress. Bald cypress cannot be split across the growth rings even in longer pieces of the slimmest stem, which is why it cannot be used for fencing.” Look for this giant, Bald Cypress, near the Children’s Wading Pool.
Possum-haw (Ilex decidua) is entry #3. This gem, found opposite the Parks Office, is a favorite of birds. The reddish-colored berries attract songbirds and small-mammals. Nectar-insects favor this understory tree, too. It is a favored nesting site as well and its winter color can be spectacular. Anaqua (Ehretia anacua) is a strikingly beautiful tree when in bloom. The Arboretum Guide’s entry No. 15, Anaqua grows primarily in South Texas and Mexico because of its cold intolerance. Landa Park’s specimen grows near Landa Lake. German settlers gave the tree the name vogelbeerenbaum due to its popularity with birds. Bees, too, love these blossoms. The light brown wood of Anaqua is hard and heavy. These characteristics make the wood a prized choice for posts, tool handles, and similar uses. Be sure to feel the Anaqua’s leaves. You will know immediately why it is referred to as “sandpaper” tree. Pecan (Carya illinoensis), entry #18, became the State Tree of Texas in 1919, following the request by Gov. James Stephen Hogg that a pecan tree mark his grave. Pecan is the only true nut that is native to the U.S.A., part of a multi-million-dollar industry in our state. Some species of pecan trees can live to 300 years. The Landa Park pecans are located near Gazebo Circle. Another pecan, planted as a Memorial Tree for Marie Offerman, grows along the Mill Race. Mrs. Offerman served as Chaplain of Friends for the Preservation of Historic Landa Park from its inception until her death in 2018. These six tree species are but a small example of those awaiting your next visit to Landa Park. Use the map included in the Arboretum Guide. Think about their place, indeed their importance, in the environment. Be grateful — grateful for folks like Bill and Dolores Schumann because they and friends cared enough to help protect and then record the importance of these botanical witnesses.

Trees need People. People need Trees. Twenty-two Benefits of Trees
|
#1
TREES COMBAT CLIMATE CHANGE |
Excess carbon dioxide (CO2) is building up in our atmosphere, contributing to climate change. Trees absorb CO2, removing and storing the carbon while releasing oxygen back into the air. In one year, an acre of mature trees absorbs the same amount of CO2 produced when you drive your car 26,000 miles. |
|
#2
TREES CLEAN THE AIR |
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark. |
|
#3
TREES PROVIDE OXYGEN |
In one year an acre of mature trees can provide enough oxygen for 18 people. |
|
#4
TREES COOL THE STREETS AND THE CITY |
Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased. Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves. |

How to Plant a Tree the Right Way — 7 Steps for Getting it Right Every Time
|
BY JOE LAMP'L
APRIL 18, 2017 How to plant a tree the right way can return years of happy returnsWith a little luck and good timing, sometimes simply sticking a tree in the ground and walking away can be enough for it to survive. But knowing how to plant a tree the right way, will ensure success every time. In my book, there are 7 steps for planting success which I share below. Suffice it to say, I’ve learned these all-important steps mostly by trial and error. It’s always the best way to learn, especially when it comes to gardening. Trees have been described as the lungs of the earth for good reason. Without them, there would be no life on this planet. That’s reason enough to plant as many as we can. But when you learn just how important they are for so many reasons, you begin to understand my passion for trees and why we need more. |
That’s led to a lifelong crusade to encourage people to plant more trees. Or even one. So it only stands to reason how thrilled I was to team up with Lands’ End recently to encourage everyone to #PlantATree in celebration of Earth Day this year. So whether this is your first tree planting, or you’ve planted a forest by now, we’re always learning. Knowing how to plant a tree the right way — especially now, considering such unprecedented climate conditions — will ensure your efforts will not be in vain. To give you the whole story, check out this video we created to walk you through how to plant a tree the right way, along with the 7-steps for getting it right every time. |
Introduction to Oak Wilt (Texas A & M)
|
Oak wilt, one of the most destructive tree diseases in the United States, is killing oak trees in central Texas at epidemic proportions. Oak wilt is an infectious disease caused by the fungus Bretziella fagacearum, which invades and disables the
|
water-conducting system (xylem) in oaks. All oaks can be infected by the fungus that causes oak wilt; however, some oak species are affected more than others. The successful management of oak wilt depends on correct diagnosis and an understanding of how the pathogen and different oak species interact.
|
|
Red Oaks
Members of the red oak group, particularly Texas red oak (aka Spanish oak), Shumard oak, blackjack oak, and water oak are the most susceptible of the fungus and may play a unique role in the establishment of new oak wilt infections. Red oaks never survive oak wilt and often die within 4 to 6 weeks following the initial appearance of symptoms. During summer months, diseased red oaks can often be spotted from a distance because of their bright, autumn-like coloration in contrast to the surrounding greenery. This symptom is called flagging. |
|
White Oaks
Members of the white oak group include post oak, bur oak, Mexican white oak, white shin oak, Durand oak, Lacey oak, and chinquapin oak. Although white oaks show some tolerance of the disease, all oaks can be infected by the fungus. White shin oak, Lacey oak, and chinquapin oak can grow in stands with interconnected root systems, enabling the fungus to possibly infect adjacent trees are susceptible to the fungus. Many infected white oaks will exhibit some canopy loss and generally the disease will not spread to adjacent trees. Lacey oaks, white shin oaks, and chinquapin oaks sometimes form root connections similar to live oaks, offering a pathway for the disease to spread to adjacent trees, causing higher infection and mortality rates than in other white oak species. |
|
Live Oaks
Live oak and Texas live oak are intermediate in their susceptibility to oak wilt, but are most seriously affected due to their tendency to grow with vast, interconnected root systems that allow movement of the fungus among adjacent trees. Most live oaks defoliate and die within 3 to 6 months following initial appearance of symptoms. Some live oaks take longer to die, and a few untreated trees may survive many years in various stages of decline. Occasionally, a few live oaks in an oak wilt center may escape infection and remain unaffected by the disease. |

Oak Wilt Quick Guide
Early detection and prompt action are essential for successful management of oak wilt. The specific measures taken depend on several circumstances but should include appropriate combinations of the following:
Prevent New Infections
Diversify Your Landscape
Stop Spread through Root Connections
Inject High-Value Oaks with Fungicide
Prevent New Infections
- Remove and dispose of oak wilt-infected red oaks immediately.
- Avoid wounding oak trees, including pruning, from February through June.
- Sterilize/sanitize all pruning equipment between trees.
- Paint all wounds and fresh stumps immediately regardless of season.
- Handle oak firewood cautiously, burn all firewood before spring, and never store unseasoned oak wood from infected trees near healthy oaks.
- Cover unseasoned firewood (from infection centers and unknown origins) with clear plastic and bury the edges of the plastic.
Diversify Your Landscape
- Plant trees that are native and/or adapted to your area.
- Favor a diversity of tree species.
- Avoid wounding oaks during planting.
- Find the right tree for your property here.
Stop Spread through Root Connections
- Install a trench at least 4 ft deep and 100 ft beyond the perimeter of infection centers (last symptomatic tree) to break up root connections.
- Cut or uproot all trees within the 100-ft barrier (except those injected with fungicide).
- Find trenching vendors here.
Inject High-Value Oaks with Fungicide
- Identify susceptible, high-value oak trees in proximity to expanding oak wilt infection centers.
- Consult a trained and licensed arborist (with certified applicator’s license) for treatment of susceptible trees with injections of propiconazole.
Central Texas Oak Wilt — Forestry Fact Sheet - TX 1
What is oak wilt? Oak wilt is an aggressive fungal pathogen (Ceratocystis fagacearum) that affects many species of oak, killing thousands of trees each year in woodlots and home landscapes.
Where is it in Texas? The Hill Country and Central Texas areas have been particularly hard hit by this disease. This map shows the extent of its damage in 2007 with yellow counties having a few incidences and the brown counties recording over 400 mortality areas. Oak wilt has been called one of the most destructive tree diseases in the United States and is at epidemic proportions in the Central Texas Hill Country.

Rivers in the Sky: How Deforestation Is Affecting Global Water Cycles
A growing body of evidence indicates that the continuing destruction of tropical forests is disrupting the movement of water in the atmosphere, causing major shifts in precipitation that could lead to drought in key agricultural areas in China, India, and the U.S. Midwest.
|
BY FRED PEARCE • JULY 24, 2018
Every tree in the forest is a fountain, sucking water out of the ground through its roots and releasing water vapor into the atmosphere through pores in its foliage. In their billions, they create giant rivers of water in the air – rivers that form clouds and create rainfall hundreds or even thousands of miles away. But as we shave the planet of trees, we risk drying up these aerial rivers and the lands that depend on them for rain. A growing body of research suggests that this hitherto neglected impact of deforestation could in many continental |
interiors dwarf the impacts of global climate change. It could dry up the Nile, hobble the Asian monsoon, and desiccate fields from Argentina to the Midwestern United States. Until recently, the nuggets of data delivering such warnings were fragmented and often relegated to minor scientific journals. But the growing concerns came to the fore in reports presented at two forest forums held by the United Nations and the Norwegian government in recent weeks. |

Why Trees Are Important to the Environment?
Trees help clean the air we breathe, filter the water we drink, and provide habitat to over 80% of the world's terrestrial biodiversity. Forests provide jobs to over 1.6 billion people, absorb harmful carbon from the atmosphere, and are key ingredients in 25% of all medicines. Have you ever taken an Aspirin? It comes from the bark of a tree!
Here are the six pillars that explain why trees are vital:
Here are the six pillars that explain why trees are vital:
|
AIR
Trees help to clean the air we breathe. Through their leaves and bark, they absorb harmful pollutants and release clean oxygen for us to breathe. In urban environments, trees absorb pollutant gases like nitrogen oxides, ozone, and carbon monoxide, and sweep up particles like dust and smoke. Increasing levels of carbon dioxide caused by deforestation and fossil fuel combustion trap heat in the atmosphere. Healthy, strong trees act as carbon sinks, offset carbon and reducing the effects of climate change. https://onetreeplanted.org/pages/why-trees |
|
WATER
Trees play a key role in capturing rainwater and reducing the risk of natural disasters like floods and landslides. Their intricate root systems act like filters, removing pollutants and slowing down the water’s absorption into the soil. This process prevents harmful waterslide erosion and reduces the risk of over-saturation and flooding. According to the UN Food and Agriculture Association, a mature evergreen tree can intercept more than 15,000 litres of water every year. |
|
BIODIVERSITY
A single tree can be home to hundreds of species of insect, fungi, moss, mammals, and plants. Depending on the kind of food and shelter they need, different forest animals require different types of habitat. Without trees, forest creatures would have nowhere to call home. - Young, Open Forests: These forests occur as a result of fires or logging. Shrubs, grasses, and young trees attract animals like black bears, the American goldfinch, and bluebirds in North America. - Middle-Aged Forests: In middle-aged forests, taller trees begin to outgrow weaker trees and vegetation. An open canopy allows for the growth of ground vegetation preferred by animals like salamanders, elk, and tree frogs. - Older Forests: With large trees, a complex canopy, and a highly developed understory of vegetation, old forests provide habitat for an array of animals, including bats, squirrels, and many birds. |
