Trees in the City

    In desert regions people congregate around oases and waterways, planting shade trees left and right. In Seattle's pioneer era, settlers were forced to fell the unbroken forest in order to enjoy such amenities of civilization as roads, buildings, sewers, orchards and gardens. Trees were converted into lumber, street pavers, piers, and telephone poles for what Chief Seattle called "talking wires." Trees were also our main export cash crop. So it was a logical farewell to the forest; hello to the big city and bright lights.
    Seattle transformed itself from just another backwater "forest primeval" --a dripping wet soft green wilderness-- into a heavyweight, hard-edged, gray-tinted city with puddles beyond telling. But since the 1970s our dawning awareness of a need to balance all facets of the urban matrix has caused a shift in emphasisand much arguing as well. Trees are right in the middle of the controversy.
    Trees cause problems as well as affording beauty, clean air, and their myriad environmental benefits. They buckle sidewalks, grow into wires, block views, intercept light, drop leaves and fruits, attract bugs and rats, shed limbs, and often blow down. Is it any wonder that dozens of companies specialize in tree removal and not one in tree planting?
    But for all the trouble they cause, trees do more good than bad. Just visualize Seattle with no trees at all, and think how ugly the place would be. Imagine the unbroken wind. Summers would be hotter and drier. More slides would occur, more flooding. The air would be less fragrant, more acrid. Wildlife and associated plants would be hurt. Seattle would be hellish, and be looked upon with pity by cities elsewhere. Fortunately for tree-huggers, trees have never had so many friends. Local trees benefit from PlantAmnesty, TREEmendous Seattle, Tree Stewards, the Arboretum Foundation, and many smaller associations.
    Next time someone complains about trees, keep in mind not only the individual situation, but the big picture and the long run. The average Seattle resident probably stays at any one location for less than 10 years. Many trees here live for more than a human lifespan. A tree can simultaneously block your view of the mountains, while being the most attractive landmark in the neighborhood.
    To call trees "attractive" is to damn with faint praise. Trees, unlike buildings, streets or cars, present seasonal changes, being living calendars that dramatically unfold their celebration of life, from the day they sprout as tiny seedlings to the day they die. When the most beautiful and thriving trees coexist near noble buildings, it results in a powerful union of natural and human forces. Call it synergy, or the potency of vivid contrast, but regardless of our terminology or explanation, the sum is glorious to behold. Since most tree plantings and architecture are unremarkable, the few instances where both elements do match perfectly become all the more precious.
    Let's single out a few superb examples of trees and buildings. These tend to make everyone happy because you'll either like the trees or the buildings, if not both. Such combinations vary much in their ability to uplift viewers. For how people perceive beauty is determined both by our state of mind or receptivity, and by external phenomena, and both fluctuate. For example, happiness is your lot if you're in love, a full moon illuminates the sky, and soothing quiet surrounds you. On the other hand, suppose you're cranky, running late, it's raining, and a gang of teenagers are screaming obscenities nearby. You get the picture. So when your mood is right, immerse yourself in whatever comforting associations or beauty you hunger for. Contemplating favorite trees, gardens, views, or other natural features can rest one's mind from its normal obsession with human matters, and help tilt our perspectives to a broader balance.

Yoshino cherry trees

    Seattle's best known example of a superb blend of fine architecture and trees may be the Yoshino cherries of the U.W. campus liberal arts quadrangle. The neo-Gothic motif brick buildings provide dignity, formal structure and an air of enduring timelessness. The trees lend seasonal delineation, informality, the excitement of life, and an annual floral display in March or April which elevates everyone wonderfully. If the trees were gone the quad would seem a desolate expanse of lawn. If the buildings were modern dark glass boxes, no number of trees would win people over. The existing conditions provide a rare match that raises eyebrows and earns widespread admiration. The buildings were constructed between 1917 and 1950; the trees were moved from the arboretum to the campus when the Evergreen Point floating bridge was built in the early 1960s.
    Next go look at the trees around Holy Names Academy on Capitol Hill (21st Ave E, south of E Aloha St). Although the street-tree elms are heartening, I prefer the dark, majestic Atlas cedar dominating the front lawn. The way its roots grip the earth is especially fascinating. Among Seattle's largest at some 100 feet in height, it probably dates, like the school, from 1910. Gaze upon that noble tree and its monumental, domed building, and tingle with good feelings.

    For a far less institutional building that nestles cozily among great trees, consider a charming stone cottage, on Lake Washington Boulevard in the arboretum, close to Madison street. As the boulevard gently slopes and curves north from Madison, it is lined with shade trees planted in the fall of 1907. They are 22 English oaks, 8 hybrid planes (also called sycamores), 3 Oriental planes, 2 Turkish oaks, and 1 cypress oak. These trees, some now more than 100 feet tall, are among the very first called for by the Olmsted Brothers landscape architects, in their plan for Lake Washington Boulevard --which predated the arboretum by decades.
    In 1936-37 the stone cottage was built with WPA labor, one of many valuable projects done during the Great Depression years. The cottage features massive stones and algae-coated timbers, some light touches of concrete, a patina copper roof, and glazed windows. Except for the discordant unnaturally bright green plastic sign on its door, and an occasional motorcycle marring its front porch, it is wholly evocative of much earlier times. It recalls fairy tales --Hänsel and Gretel could live here. The trees and other plants frame it perfectly. Numerous ferns grow among mossy boulders and leggy rhododendrons.
    These three examples I've just highlighted in this article could be multiplied. Entire blocks boast architecture and street-trees uniting to form a continuous delight. Be glad to live in a region rich with diversity of trees and built structures; revel in your own favorites. Think twice before you give a tree the kiss of death.
