Key Takeaways
1. Trees as Ancient Deities and Life-Givers
Because they are larger and older than we can ever hope to be, because they give shade, wood, food, and shelter, and because they stretch from earth to heaven, trees have been our gods since before recorded time.
Sacred reverence. Ancient cultures revered trees as divine entities, linking them to the cosmos and the cycle of life and death. Sacred groves were places of worship, leading to biblical prohibitions against planting trees near altars, as seen in Deuteronomy and Judges. This reverence stemmed from their immense size, age, and life-sustaining properties.
Universal symbolism. The Tree of Life, a universal symbol, connected the underworld to the heavens, with roots deep in the earth and branches reaching the sky. It was believed to be a perch for souls awaiting rebirth, and in Turkish lore, a falling leaf signified death. The Norse Yggdrasil, an ash tree, embodied this cosmic connection.
- Tree of Life: Roots in underworld, branches support heavens.
- Perches for souls: Children's souls waiting to be reborn.
- Turkish lore: Falling leaf means someone died.
- Norse Yggdrasil: Traditionally an ash tree.
Essential sustenance. Beyond spiritual roles, trees were fundamental for human survival, providing food, shade, shelter, and fuel. From the Garden of Eden's fruit trees to the practical needs of early humans, dependence on trees shaped societies. Even today, their products are indispensable, highlighting an enduring, multifaceted relationship.
2. The Dual Nature of Human-Tree Relationship: Reverence and Exploitation
The conflict between use and reverence is not new.
Historical tension. Humanity's relationship with trees has always been marked by a tension between deep reverence and practical exploitation. Ancient societies, while worshipping trees, also cleared forests for agriculture, recognizing that fertile land for crops often meant removing trees. This balance was a constant challenge.
Resource demands. The need for timber, especially for shipbuilding, led to widespread deforestation, as seen in Europe's dwindling forests. Even in the New World, settlers cleared vast tracts for farming, often moving on when the soil was exhausted. This exploitation was sometimes a deliberate act of dominance, like the British felling the "Liberty Tree" in Newport, Rhode Island.
- European forests depleted for shipbuilding.
- American settlers cleared forests for farming.
- British troops cut down "Liberty Tree" as dominance.
Modern paradox. Today, this conflict persists. Despite understanding trees' role in counteracting global warming, our reliance on their products, from paper to furniture, remains high. John Evelyn's 17th-century plea to replant trees in Sylva, and William Penn's vision for Philadelphia as a "greene country towne," underscore the long-standing awareness of this delicate balance.
3. Trees as Living Libraries of History and Culture
The World is a great Library and Fruit-trees are some of the Bookes wherein we may read and see plainly the Attributes of God.
Etymological insights. The names of trees, both common and botanical, are rich with historical and cultural narratives. The shared Old English root 'treow' for "tree" and "truth" suggests their steadfast nature. Latin names like Prunus amygdalis (almond, meaning "plum") or Fagus (beech, from Greek "to eat") reveal ancient uses and classifications.
- "Tree" and "truth" share Old English root 'treow'.
- Almond: Prunus amygdalis ("plum").
- Beech: Fagus (from Greek phagein, "to eat").
- Clove: From French clou ("nail").
Folklore and mythology. Trees are central to countless legends, embodying human emotions and experiences. The almond tree, for instance, symbolized rebirth and hope, as seen in the Greek legend of Phyllis or Aaron's budding rod. The trembling aspen, despite its toughness, was associated with timidity and shame in Christian and Native American lore.
- Almond: Phyllis legend, Aaron's rod (rebirth).
- Aspen: Trembling leaves (timidity, shame) in Christian/Native American legends.
- Cypress: Kyparissos's transformation (mourning, death).
Practical and medicinal lore. Historical texts like Gerard's Herball detail extensive medicinal uses, from almond oil for urinary complaints to elder bark for healing wounds. Trees also provided essential materials: alder wood for underwater construction, birch bark for canoes, and beech wood for early books, demonstrating their integral role in daily life.
- Almond oil: Good for urinary complaints (Gerard's Herball).
- Alder wood: Best for underwater construction (Venice pilings).
- Birch bark: Used for canoes (Native Americans), early writing.
- Beech bark: Used for early books, mattresses.
4. Global Journeys and Botanical Discoveries
War for plant lovers is different from war for politicians.
Botanical expeditions. European explorers and botanists embarked on perilous journeys to discover and collect new plant species, often driven by scientific curiosity or economic gain. Figures like William Bartram, David Douglas, and Robert Fortune braved harsh conditions, sometimes disguised, to bring exotic plants back to Europe.
- William Bartram: Explored Florida, discovered Franklin tree.
- David Douglas: Collected Douglas fir, Monterey pine, noble fir.
- Robert Fortune: Smuggled tea plants from China, introduced China fir.
- Engelbert Kaempfer: Found ginkgo in Japan.
Plant migration. Trees spread across continents through various means: intentional cultivation by traders (e.g., Arabs bringing coffee and cinnamon), accidental transport (e.g., paulownia seeds in porcelain packing), or natural dispersal (e.g., coconuts floating across oceans). These migrations profoundly altered global flora.
- Coffee: Spread by Arabs from Ethiopia.
- Cinnamon: Portuguese discovered true source in Ceylon.
- Paulownia: Seeds spread inadvertently from porcelain packing.
- Coconuts: Shipwreck off Florida coast led to rapid colonization.
Transformative impact. The introduction of new trees had immense societal consequences. Cinchona bark revolutionized malaria treatment, enabling European colonization of tropical regions. Coffee and tea became global commodities, shaping social customs and economies. These botanical exchanges, however, often involved exploitation and dramatic personal stories of discovery and loss.
- Cinchona: Quinine controlled malaria, aiding European expansion.
- Coffee: Became a global beverage, leading to coffee houses.
- Tea: British broke Chinese monopoly by planting in India.
- Mahogany: Valued for shipbuilding and furniture, often from slave labor.
5. The Astonishing Adaptations and Resilience of Trees
Shaking and quaking in trees, as in religious sects, is not necessarily a sign of weakness.
Ingenious survival. Trees exhibit remarkable adaptations to diverse and challenging environments. Aspens, for example, have flattened leaf stalks that allow their leaves to tremble, preventing wind damage. Baobabs store vast amounts of water in their spongy trunks, enabling survival in deserts.
- Aspen: Trembling leaves avoid wind damage.
- Baobab: Stores water in spongy trunks.
- Mangrove: Stilt roots, pneumatophores for saline, low-oxygen environments.
- Joshua Tree: Spiky, waxy leaves conserve water in desert.
Extreme longevity. Many tree species demonstrate incredible resilience and lifespan. Bristlecone pines can live for nearly 5,000 years, and redwoods for thousands, enduring fires and harsh conditions. Their ability to regenerate from roots (aspens, cork oaks) or fire-activated seeds (eucalyptus, redwoods) ensures their continuity.
- Bristlecone Pine: Methusela tree, ~4700 years old.
- Redwoods: Live for thousands of years, fire-resistant bark.
- Eucalyptus: Buds sprout after fire, seeds need heat to germinate.
- Cork Oak: Regenerates bark every few years.
Intricate ecosystems. Trees are often part of complex, interdependent relationships. Fig trees rely on specific fig wasps for pollination, and yucca plants depend on yucca moths. Mangroves, with their stilt roots and salt-exuding leaves, create unique coastal ecosystems that protect against erosion and support diverse marine life.
- Fig trees: Rely on fig wasps for caprification.
- Yucca plants: Pollinated by pronuba yucca moth.
- Mangroves: Support intricate food chains, protect coastlines.
- Koalas: Feed almost exclusively on eucalyptus leaves (despite toxins).
6. Trees as Markers of Human History and Progress
No judge these days would depend on a witness identifying the tree under which a crime took place!
Historical milestones. Trees have served as silent witnesses and symbols throughout human history. The "Liberty Tree" in Newport, Rhode Island, became a focal point of revolutionary sentiment. The sycamore maple under which the Tolpuddle martyrs met marked a pivotal moment in labor history.
- "Liberty Tree": Symbol of American Revolution.
- Tolpuddle martyrs: Met under a sycamore maple.
- Joshua trees: Guided Mormons to their promised land.
- Japanese cedar: Avenue of sugi trees to Shogun burial site.
Evolving utility. Human progress and changing needs have continually redefined the utility of trees. Pine wood, once crucial for naval masts, later fueled the American logging industry for houses and matches. Cork, initially for shoes and fishing nets, became essential for soundproofing and wine preservation, reflecting technological and lifestyle shifts.
- Pine: Masts for ships, then houses, matches, turpentine.
- Cork: Shoes, fishing nets, soundproofing (Proust's room), wine stoppers.
- Rubber: Waterproofing (Mackintosh coats), tires (Goodyear).
- Ebony: Luxury wood for chessmen, piano keys, fine furniture.
Loss of intimate knowledge. In modern times, the intimate knowledge of individual trees, once vital for survival and cultural understanding, has diminished. Unlike the biblical story of Susannah, where identifying a specific tree was crucial for justice, contemporary society often lacks this detailed connection, relying instead on commercial products and fossil fuels.
- Susannah's trial: Elders failed to identify tree, proving their lie.
- Modern disconnect: We buy products, heat with fossil fuels.
- Street names: We live on "Elm Street" but can't identify an elm.
7. The Enduring Spiritual and Emotional Resonance of Trees
Planting a tree is a small way of saving a bit of our planet; it is also a kind of prayer.
Personal connection. Beyond their practical uses, trees hold deep emotional and spiritual significance for humans. The act of planting a tree is often seen as an act of hope, a connection to the future, and a personal prayer for the planet's well-being, as exemplified by Rabban Yochanan ben Zakkai's teaching.
- Rabban Yochanan ben Zakkai: Plant sapling before greeting Messiah.
- Author's experience: Planting trees around his Pennsylvania home.
- Husband's role: "Just a tree in the background" but most important.
Inspiration in art. Trees have consistently inspired artists, poets, and writers, serving as powerful metaphors for life, love, sorrow, and wisdom. Andrew Marvell's "The Garden" depicts the soul gliding into tree boughs, while Tennyson's "immemorial elms" evoke timeless beauty and melancholy.
- Andrew Marvell: Soul glides into boughs "like a bird."
- William Cowper: "Yardley Oak" as "king of the woods."
- Robert Frost: "Swinger of birches" as a metaphor for life.
- Van Gogh: Tortured cypresses reaching heavens.
Modern solace. From ancient sacred groves to modern "forest bathing" (shinrinyoku) in Japan, trees offer solace and rejuvenation. The author's personal joy in planting trees, and the story of his son playing a "tree in the background," underscore the quiet, profound importance trees hold in our lives, often playing the most significant, if understated, roles.
- Japanese "forest bathing": Seeking relaxation in deep, quiet forests.
- Chinese gardens: Listening to rain on banana leaves for pleasure.
- Goethe: Explored meaning of ginkgo leaf, seeing himself as "one and as two."
