Forest

 

Consider a forest: One notices the trunks, of course, and the canopy. If a few roots project artfully above the soil and fallen leaves, one notices those too, but with little thought for a matrix that may spread as deep and wide as the branches above. Fungi don’t register at all except for a sprinkling of mushrooms; those are regarded in isolation, rather than as the fruiting tips of a vast underground lattice intertwined with those roots. The world beneath the earth is as rich as the one above.

For the past two decades, Suzanne Simard, a professor in the Department of Forest & Conservation at the University of British Columbia, has studied that unappreciated underworld. Her specialty is mycorrhizae: the symbiotic unions of fungi and root long known to help plants absorb nutrients from soil. Beginning with landmark experiments describing how carbon flowed between paper birch and Douglas fir trees, Simard found that mycorrhizae didn’t just connect trees to the earth, but to each other as well.

Simard went on to show how mycorrhizae-linked trees form networks, with individuals she dubbed Mother Trees at the center of communities that are in turn linked to one another, exchanging nutrients and water in a literally pulsing web that includes not only trees but all of a forest’s life. These insights had profound implications for our understanding of forest ecology—but that was just the start.

It’s not just nutrient flows that Simard describes. It’s communication. She—and other scientists studying roots, and also chemical signals and even the sounds plant make—have pushed the study of plants into the realm of intelligence. Rather than biological automata, they might be understood as creatures with capacities that in animals are readily regarded as learning, memory, decision-making, and even agency.

Plants communicate, nurture their seedlings– and feel stress.  An interview with Suzanne Simard: “Never Underestimate the Intelligence of Trees.”

Pair with: “Should this tree have the same rights as you?

As we contemplate cultivation, we might recall that it was on this date in 1602 that The Bodleian Library at Oxford formally opened.  (Sir Thomas Bodley had donated over 2000 books in his personal library to replace the earlier Duke of Glouchester’s (Duke Humphrey’s) Library, which had been dispersed.  Bodley’s bequest was made in 1598; but the full collection wasn’t catalogued and made available until this date in 1602, when the Library reopened with its new name, in honor of its benefactor.  Eight years later, Bodley made a deal with the Stationer’s Company– which licensed [provided copyright] for all publications in England– that a copy of everything licensed should be sent to the Bodleian…  making it a Copyright Depository, the first and now one of six in the UK.)
