Willow, willow
This is the initial entry here about the Prefumo Creek Restoration and Enhancement Project, my main activity for the past three years.
As the second and largely solitary portion of the project nears completion, my attention is turning from weed-whacking, chainsawing and mulch-moving to making it accessible to more people, rebuilding lapsed institutional support for its further expansion, telling its story and studying its lessons.
That study led me yesterday to a Google search about the bizarre growth habits of its dominant occupant, the Arroyo Willow. Buried deep in the list of uninformative links, I discovered a marvellous scientific paper published in September 2024: THE ROLE OF PARTIAL LIMB BREAKS IN THE GROWTH AND PERSISTENCE OF ARROYO WILLOW (SALIX LASIOLEPIS),
Its subject has intrigued me ever since I started cutting a pathway through the thicket of willows along the creek bank to open views of the incised channel 15 feet below. The heavy trunks of the oldest trees crawl up from the stream bed and grow horizontally along the ground conveniently providing trail borders and benches before pivoting upward into leafy crowns.
The paper author’s onomatopoeic term for such trees seemed perfect: “decumbent sprawlers.” It captured the combination of weighted immobility and reptilian motion that I sensed passing them on my daily walks. He provided an ecological explanation for their animated shape as the final stage of the tree’s growth. Young willows spring up single and erect to compete for light as do other pioneer species. Those which are shaded die out, while the survivors sprout multiple trunks from their bases, turning from trees into shrubs. Their rapid accumulation of biomass leads to breakage of limbs and trunks that cant be supported under the stress of weight and wind. Such breaks would leave other species liable to infection, weakening and mortality. But willows can tolerate open wounds indefinitely, and their broken limbs continue to grow and heal even if thinly attached. They re-root when touching the ground, where they continue growing horizontally and mature as sprawlers that sprout decumbent vertical shoots which thrive in the light opened by the breaks.
Upon returning to the creek the next morning, I came upon a large branch that must have broken the night before, while I was reading the article. Instead of an ugly marker of weakness and injury that needed to be cleared, I saw it now as the tree’s extension of territory and length of life.
I’d been led to the paper listening to the first chapter of Landmarks, a 2017 book written and narrated by Robert MacFarlane, mountaineer, naturalist, Cambridge English professor, and splendid stylist, while while walking with the dog at Pismo Beach. His thesis about the interrelation of language, literature and appreciation of nature is a variant of the one guiding the Cal Poly class I taught from 1998 until retirement in 2014, “Ecolit, Reading and Writing the Landscape,” its syllabus headed by a quote from Thoreau
Where is the literature which gives expression to Nature? He would be a poet who could impress the winds and streams into his service, to speak for him …whose words were so true, and fresh, and natural that they would appear to expand like the buds at the approach of spring, though they lay half smothered between two musty leaves in a library.
Grieving for the new Oxford Junior Dictionary’s culling of words like acorn, fern, otter and pasture, which named particulars of the natural world, and their replacement with terms like attachment, chatroom, and voicemail– supposedly of more relevance to modern children–MacFarlane includes glossaries of traditional local words for landscape features, plants, and animals whose loss accompanies the loss of the features they name under the pressure of industrial/commercial development. Naming, he observes, is the prerequisite for knowing, a point confirmed by my subsequent discovery of “sprawler.”
In addition to preserving dying vocabulary, MacFarlane practices literary criticism in appreciation of obscure books of nature writing, like The Living Mountain, a volume of essays by Nan Shepherd produced in the course of her wanderings through the Cangorns, a range on the island of Lewis in the Outer Hebrides of Scotland, which he has explored since early childhood visiting his grandfather there.
Facing an abyss of unstructured time at this interval of the Prefumo project, MacFarlane encourages me to relate to the Creek in a different way, to make the difficult transition from physical activity back to my earlier academic engagement with reading and writing the landscape.
