Last week I was fortunate to attend and offer a small Forest Therapy walk following a symposium on The Transformative Properties of Horticulture, sponsored by the Madison Square Park Conservancy. The symposium featured inspiring speakers engaged in breathtakingly impactful work.
Naomi Sachs, a professor of therapeutic landscape architecture at University of Maryland and founder of the Therapeutic Landscapes Network, a resource for gardens and landscapes that promote health and well-being, spoke about "restorative landscapes" and the importance of providing access to nature in healthcare settings. Hospitals are stressful places where patients and their visitors are at their most vulnerable. “Health”, she added, is not just “not being sick”. It is also about physical, emotional, and spiritual wellbeing, which is enhanced by natural environments. She described the notion of “restorative landscapes”, which are landscapes that promote health and wellbeing, and could be as simple as a fire escape or memorial--any place that where a person can find peace and solace.
Sachs described the many scientific and medical studies supporting the beneficial impact of nature, including—among medical patients—more rapid recovery from surgery, reduced patient complaints, and reduced need for medication, and--among the general population--improved memory and attention and a reduction in ruminative thoughts.
Gwenn Fried, Manager of Horticulture Therapy Services at NYU Langone Medical Center, then spoke about therapeutic horticulture in public spaces and underscored the value of targeting the certain populations that can most benefit from it, including:
Regina Ginyard and Jenn Hertzell then engaged the audience in a networking activity focused on green spaces that give people joy. Ginyard is a founding member of Black Urban Growers (BUGS), an organization committed to "building networks and community support for growers in both urban and rural settings." Jenn Hertzell is a Bronx-based farmer and founder of At the Rood: An Herbal Eastery, Farm, and Apothecary that exists to create opportunities for people of the African Diaspora to hear their relationships with their bodies and with the earth.
How fortunate we are that scholars and practitioners like Sachs, Fried, Ginyard, and Hertzell are improving lives through the transformative properties of horticulture.
Stay tuned for my next blog entry to learn about what Amos Clifford said at the conference.
Dr. Yoshifumi Miyazaki spoke yesterday at the Japan Society, describing his findings about seeking wellness through nature. Miyazaki coined the term “forest therapy” in 2003 as a way to convey the essence of the Japanese term “shinrin-yoku” (forest bathing).
Miyazaki is generally considered the father of Forest Therapy. His key insight is that the human body is made for nature. Humans evolved over a 6-7 million year period; the time since the Industrial Revolution—that is, the introduction of the urban world—represents just .01% of that time span. Urbanization has led to overwork for our brains and bodies; nature offers a return to a calming normal state.
Miyazaki has supported this finding with abundant, seminal research, both in laboratory and field experiments. In one lab study, the presence of merely a bouquet of roses on a desk resulted in a calming effect on the brain’s prefrontal cortex activity. A similar effect resulted from the scent of air-dried wood chips. Similarly, a calming effect was identifiable when a subject viewed an image of forest scenery versus city scenery and when a subject’s hand ran over uncoated wood versus wood featuring urethane and other finishes.
Field experiments produced similar results. Parasympathetic nervous activity, which helps with relaxation and slows the heart rate, increases in forests, both from 15 minutes of viewing a forested area versus an urban area and from 15 minutes walking in a forested area versus an urban area. Likewise, the stress hormones Cortisol and Adrenaline decrease when humans view or walk in forested settings. Notably, these measures, as well as blood pressure and pulse rates, remain reduced for several days following a few hours in a forested area.
Miyazaki also reported on his studies of the impact of nature therapy for depressed and highly stressed people. There too, even a Bonsai tree or bouquet of flowers sitting on a desk had a favorable impact. The favorable impact was felt by healthy people (with a 15% improvement in parasympathetic nervous activity); however, in highly stressed people the improvement was nearly 100%.
Miyazaki's findings are a reminder that the benefits of Forest Therapy are available to almost everyone. While access to a park or garden, or of course a rural setting, is desirable, his research shows that significant improvements in physiological relaxation are achievable even with the presence of essential oils, recordings of natural sounds, natural wood products, and flowers and other house plants.

From time to time I play a thought experiment that involves reflecting on what it took to arrive at a certain moment in time in my life—the people, circumstances, choices, and opportunities that led to my doing something as routine as commuting to work or sending a text to a friend. Perhaps I owe this way of thinking to Carl Sagan’s comment, “If you wish to make an apple pie from scratch, you must first invent the universe.”
I found myself engaging in this experiment while walking among the crowds that had gathered in lower Manhattan on Friday, September 20 to bring attention to climate change. What has it taken for us to arrive at this point?
With a nod to Sagan, first we needed a universe--a Big Bang, and the creation of Earth 4.5 billion years ago. Fast forward to the appearance of Homo Sapiens 300,000 years ago, and in time the emergence of new technologies, from the use of fibers to make baskets, clothing, and bags 26,000 years ago, to pottery for food storage and cooking 20,000 years ago. The first city, Jericho, emerges 11,000 year ago. Cattle are first domesticated 10,500 years ago, and the first depiction of a wheeled vehicle appears 5,500 years ago.
Fast forward again to the industrial revolution, 250 years ago, and the rise of machine tools and manufacturing, chemical and metal production, factories, and steam and water power, which led to unprecedented population growth. It took over 200,000 years for the human population to reach 1 billion, and 100 years for it to reach over 7 billion, leading to increased urbanization and a growing appetite for ever more natural resources.
Metals, ores, petroleum--refined, purified, rarified, smelted, condensed for our use. Plants and animals cultivated and bred for our consumption. Land devoured for our agricultural needs, roads, and sprawling mega-cities. Styrofoam and other throw-away plastic containers replace bags and baskets made from woven leaves or strips of carefully selected and tended wood. Cars and planes replace travel on foot or horseback, and even in many regions by train. Our reliance on petroleum, derived from ancient decayed plants and all the carbon they harvested, now releases that same carbon into the air.
So how did we arrive at a moment when thousands of children all over the world would be protesting inaction against climate change? There are infinite strands that lead us to this point, and I have provides the lightest of sketches here. The bigger question is, "What will it take to change the course of this ever accelerating and alarming trajectory?"
When planes struck the Twin Towers 18 years ago, New Yorkers and the world witnessed the perverse deployment of one type of human invention—airplanes—against another—skyscrapers. Of course, it was not the human-engineered aeronautic and architectural innovations themselves that resulted in the horrific loss of life, but rather al-Qaeda’s heinous scheme to appropriate them for harm.
Yet, the scale of loss could not have been achieved without the capabilities made possible by human innovation. And, while we know that airplanes and skyscrapers derive from metals and petroleum harvested from the Earth, these materials, once smelted, shaped, and refined on an industrial level, hardly appear recognizable as “nature”. On September 11th we witnessed a Frankensteinian deployment of natural resources.
What a contrast to that sinister application of human invention is the Ground Zero Memorial. With water cascading into hollowed imprints of the former sites of the two towers, names of the murdered etched into stone, and trees interspersed along the pavement, the memorial site brings together sustaining elements of nature: water, rock, and trees.
I do not know what theories underlie the planner’s vision for the memorial site, but with my office just a few blocks away, I frequently stroll through the site and am regularly taken by how comforting it is. The continual rush of the sound of falling water as it catches the daylight; the solidity of stone holding in perpetuity the names of the deceased; and the color and fragrance of shade-providing trees, along with the musical sounds of the birds they host, offer strong reminders of the solace offered by elemental nature, particularly in contrast to technology gone rogue.
Summer solstice, when the sun reaches its highest point in the sky, is an opportunity to connect with cyclical changes and embrace the bounty of nature around us. Summer is upon us, a time of abundant growth. The day that provides the most light, it is perhaps then a time for enhanced clarity and insight as well as chance to appreciate the world's plenitude.
Derived from the Latin words "sol" (sun) and "sistere" (to make stand), the word "solstice" connotes an inflection point, a moment when what is before differs from what is after, as is fitting for the day that marks a shift from the sun progressing northward to tracking southward and with this a shift from lengthening daylight hours to shortening daylight hours.
Humans have a rich traditions honoring the summer solstice. Ancient Northern and Central European pagans--including Germanic, Celtic and Slavic tribes--celebrated Midsummer with bonfires, which were thought to enhance the sun’s energy and promote a good harvest for the fall. Early Christians celebrated the day as St. John's Day, commemorating the birth of John the Baptist. The Great Pyramids of Egypt are situated such that, from the viewpoint of the Sphinx, the sun sets directly between two of the pyramids on the summer solstice. The ancient Chinese regarded the summer solstice as connected with the feminine force “yin,” and celebrated with festivities honoring Earth, femininity.
The Mayans of Central America built structures to align with the sun's solstice path. And many Native American tribes engaged in solstice rituals, some of which continue to be practiced. The Sioux sun dance entails cutting and raising a tree as a symbolic connection between the heavens and Earth, placing teepees in a circle to represent the cosmos., and participants decorating their bodies in colors of red (sunset), blue (sky), yellow (lightning), white (light), and black (night).
While many ancient cultures were attuned to the sun's cycles and engaged in solstice rituals, contemporary urban dwellers may fell less connected to this astronomical happening. But as entrenched as we may be in our day-to-day lives, the eternal dance between the Sun and Earth continues, a reminder of the extent of time beyond humanity and forces that are bigger than ourselves.
Botanists call flowers that have either male or female sex organs "imperfect", whereas flowers that contain both male and female sex organs are called "perfect". What a contrast to the negative views about human sexual diversity among all too many communities!
June marks the arrival of "Pride Month", celebrating sexual diversity and gender variance. The month includes parades and other events to foster a positive, self-affirming stance against violence and discrimination toward LGBTQ people. June, 2019 promises to be the largest celebration of LGBTQ pride in history as it marks the 50th anniversary of the rebellion at NYC's Stonewall Inn in response to a police raid.
Tolerance for human gender diversity may be an ongoing struggle, but gender variability is well recognized in the plant kingdom. Some trees, such as white ash and willow, have male and female flowers on different trees (that is, individual trees bear either male or female flowers). Others, such as beech and oak, have separate male and female flowers on the same tree. And others, such as magnolias, serviceberries, and elms, produce flowers with both male and female parts.
That gender isn't binary is apparent in the plant kingdom. And, as the courageous people standing up for LGBTQ rights have shown us, gender isn't binary among humans either. Rather, among many natural creatures, ourselves included, there are variations of gender expression, with gender manifesting along a spectrum rather than black or white.
There is much that plants can teach us, including that sexuality manifests in diverse ways.
I am a restless person. Left to my own when confronted with free time I like to go elsewhere, to get away and explore places near and far, other countries, other landscapes, other neighborhoods, and I am fortunate that circumstances allow me to do so.
Restlessness has had its rewards. It has introduced me to different people and cultures, to new perspectives and has broadened my sense of natural and human history and activity. At the same time, it can take a lot of resources to be on the go, including time, money, and pollution-emitting carbon.
Through hiking, exploring and guiding forest therapy walks, I spend much time in the presence of trees, pausing to take in their presence, to notice their form, and to contemplate their lives. Unlike animals, trees can't run away from their predators. They live their entire existence, sometimes hundreds of years, in one place (200 years in the life of a tree is the equivalent of 40 human years). Not able to run away or fight with tooth and claw, they carry their own medicine and systems to ward off danger. There's a reason so much of our medicine derives from plants: Imagine what trees have witnessed over the years as their trunks grow tall and thick and their branches reach skyward!
Of course, trees are hardly still. From large vascular systems transmitting xylem and phloem to micro-activity on a cellular level, there is much movement, even if it isn't always visible to us. Yet, other than through the disbursal of seeds, trees are not mobile, whereas we are. As a human, I am animal, with muscles and limbs that enable me to ambulate and senses that enable me to to be drawn to what I need or to turn away from what is unpleasant or dangerous. This way of being is as central to me as it is to any other creature in the animal kingdom.
Yet there is much that trees can teach us. Lately I've been thinking a lot about tuning in from time to time to a tree's perspective and the lessons to be learned. Without the impossible task of abandoning my animal self, maybe there is something to be said for staying more local, for standing tall while the activity of the world happens around me. What lessons would I absorb? What powerful medicine might I generate from such a stance?
I recall the snarky word play, "Make like a tree and leave!" Cute, maybe, but what a brusque and inapt dismissal of our botanical, oxygen-providing neighbors on which we depend.
Maybe it's time we "Make like a tree... and stay."
They stand tall, nurturing their offspring to enhance their chances of growing steadily and sturdily. They support their neighbors, transmitting messages across vast and intricate networks to ensure the community’s safety and well-being. They have withstood the cycles of many years, including challenging conditions, yet persist with grace and beauty. They are mothers – mother trees.
Much attention has focused lately on the networked nature of forests. Trees exist not simply as individuals but within a highly collaborative, interconnected system, communicating through elaborate circuitry of fungi and root tips. "Forests", notes forester Peter Wohlleben in The Hidden Life of Trees, are superorganisms with interconnections much like ant colonies" Key to this interconnectedness are "Mother Trees", a notion pioneered by Scientist Suzanne Simardin (who appears as a fictionalized character in Richard Powers' The Overstory, the subject of the prior blog). The dominant trees in forests, Mother Trees function as central nodes for extensive underground networks of roots and mycorrhizal fungi. They nurture young trees by spreading fungi to them and conveying needed nutrients.
Mother Trees also restrain the unfettered growth of young trees so that they can grow in ways that make them sturdier and more resilient.Writes Wohlleben:
" Young trees are so keen on growing quickly that it would be no problem a all for them to grow about 18 inches taller per season. Unfortunately for them, their own mothers do not approve of rapid growth. They shade their offspring with their enormous crowns, and the crowns of all the mature trees close up to form a thick canopy over the forest floor. This canopy lets only 3 percent of available sunlight reach the ground and, therefore, their children's leaves. Three percent--that's practically nothing. With that amount of sunlight, a tree can photosynthesize just enough to keep its own body from dying. There's nothing left to fuel a decent drive upward or even a thicker trunk .... [S]low growth when the tree is young is a prerequisite if a tree is to live to a ripe old age. ... Thanks to slow growth, their inner woody cells are tiny and contain almost no air. That makes the tree flexible and resistant to breaking in storms."
Slow growth also makes trees resistant to disease-bearing fungi,, which has difficulty penetrated the their tougher trunks. In the meanwhile, over a period that could last 200 years (the equivalent of 40 human years), the Mother Tree passes along sugar and other nutrients to the offspring. "You might even say they are nursing their babies," notes Wohlleben.
Thanks to the attentiveness of Mother Trees, young trees can grow up strong and resilient, and forests can thrive. The same can be said for the roles of mothers (and fathers) within human families and communities. On this Mother’s Day, consider the Mother Trees around you.
New York is the epicenter of the book publishing industry. So, in exploring NYC nature connections it is apt to note the 2019 Pulitzer Prize for fiction awarded to Richard Powers' The Overstory, a novel in which trees shape the lives of nine characters and are so vividly evoked as to be characters too. In addition, Victoria Johnson's American Eden was a finalist for the Pulitzer for history. American Eden is a riveting biography of David Hosack, visionary physician and botanist during the early Republic who created the New York's first botanical garden (more about this terrific book in a later blog).
Nature certainly received much attention from this year's Pulitzer Prize Board.
The Pulitzer Prize Board describes The Overstory as "An ingeniously structured narrative that branches and canopies like the trees at the core of the story whose wonder and connectivity echo those of the humans living amongst them."....a sweeping, impassioned work of activism and resistance that is also a stunning evocation of—and paean to—the natural world. From the roots to the crown and back to the seeds, The Overstory unfolds in concentric rings of interlocking fables that range from antebellum New York to the late twentieth-century Timber Wars of the Pacific Northwest and beyond. There is a world alongside ours—vast, slow, interconnected, resourceful, magnificently inventive, and almost invisible to us. This is the story of a handful of people who learn how to see that world and who are drawn up into its unfolding catastrophe."
With stirring, incisive descriptions, Powers awakens deep, limbic understanding of humans' biological and emotional connection to the natural world and the primacy of trees. “This is not our world with trees in it" he writes. "It's a world of trees, where humans have just arrived.” And what lessons there are to be learned from trees. Here's a passage I particularly like, one that portrays survival of the fittest not as fierce drama played out through competition among individuals but rather as a result of successfully networked, interrelated, and cooperative communities:
"The things she catches Doug-firs doing, over the course of these years, fill her with joy. When the lateral roots of two Douglas-firs run into each other underground, they fuse. Through those self-grafted knots, the two trees join their vascular systems together and become one. Networked together underground by countless thousands of mile of living fungal threads, her trees feed and heal each other, keep their young and sick alive, pool their resources and metabolites into community chests.... Her trees are far more social than [she] suspected. There are no individuals. There aren't even separate species. Everything in the forest is the forest. Competition is not separable from endless flavors of cooperation. Trees fight no more than do the leaves on a single tree. It seems most of nature isn't red in tooth and claw, after all."
There is much to learn from trees.
Inconspicuously situated at Central Park West and 77th Street stands a statue of Prussian naturalist Alexander von Humboldt (1769–1859), largely forgotten in the English-speaking world. As we approach Earth Day it is timely to consider the impact of this extraordinary polymath who invented the concept of nature's inter-connected forces and unity. At a time when Enlightenment philosophers were still grounded in Aristotle's view that "nature has made all things specifically for the sake of man" Humboldt saw the natural world as an interconnected, fragile web of life.
Humboldt's textual works, Personal Narrative, Views of Nature, and Cosmos, as well as political essays about the colonies, and his maps and graphical depiction of climate zones, inspired scientists, leaders, poets, and thinkers including Johann von Goethe, Charles Darwin, Thomas Jefferson, Simon Bolivar, Jules Verne, William Wordsworth, early environmentalist George Perkins Marsh, Erst Haeckel who term Humboldt's discipline "ecology", Henry David Thoreau, and John Muir. Entire philosophical and literary movements--German Idealism, Romanticism, and Transcendentalism--can trace their lineage to Humboldt and he revolutionized fields as wide ranging as agriculture, meteorology, zoology, geology, hydrology, and botany. Over 300 plant and 100 animal species are named after him, as are minerals, mountains, geologic formation, glaciers, waterfalls, bays, state and national parks, moon craters, and an asteroid--more than are named after anyone else.
At the source of Humboldt's influence was his relentless energy and curiosity, which in the early 1800s led him to travel widely to places where few Europeans had traveled before to conduct hands-on scientific experiments, map geologic characteristics, and collect and record botanical samples. With collections of the latest instruments, ranging from telescopes and microscopes, to barometers and pendulum clocks and compasses, he traveled 1700 miles of Venezuela's Orinoco River to the Amazon River basin, across Cuba, Mexico and Peru, (where he climbed Mount Chimborazo, an inactive volcano of nearly 21,000 feet) and across the mountains of Kazakhstan.
From evidence accumulated during his travels, he pieced together systemic patterns, similarities, and connections across contents, inventing the classification of plants by climate zones rather than taxonomy. Observing the coastal matching of Africa and South America, he sensed an ancient connection between the continents that presaged our understanding of plate tectonics. Humboldt also identified the devastating ecological consequences of deforestation, ruthless irrigation, and cash crop agriculture, decrying the impact on habitats of man's "insatiable avarice”. Moreover, Humboldt sensed and observed nature not only empirically but viscerally and emotionally. "Nature", he wrote to Goethe, "must be experience through feeling."
In her thrilling and meticulously researched biography of Humboldt, The Invention of Nature, (2015), Andrea Wulf reminds us of the contributions of this influencer of influencers and restores his rightful place among the pantheon of scientists. With the arrival of Earth Day, consider the impact of Humboldt; there are few better ways to do so than through Wulf's magnificent biography.
