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.
