This post follows last week’s post: The Forest Has a Heart?
In 2016, Zlinszky (Zlinszky/Molnar/Barfod) and his team released another study demonstrating that birch trees go to sleep at night (now we know that all trees – at least all the trees that have been studied so far – do sleep at night).
Trees follow circadian cycles responding primarily to light and darkness on a daily cycle. The researchers believe the dropping of birch branches before dawn is caused by a decrease in the tree’s internal water pressure while the trees rest. With no photosynthesis at night to drive the conversion of sunlight into simple sugars, trees are conserving energy by relaxing branches that would otherwise be angled towards the sun. Trees increase their transpiration during the morning, decreasing it during the afternoon and into the night. There is a change in the diameter of the trunk or stem that produces a slow pulse. During the evening and the night tree water use is declining, while at the same time, the stem begins to expand again as it refills with water.
When trees drop their branches and leaves its because they’re sleeping. They enter their own type of circadian rhythm known as circadian leaf movement, following their own internal tree clock. Continue reading “Trees Sleep? by Sara Wright”
Every morning I walk to the river in the velveteen hour between the vanishing blue night and the coming of the first scarlet, pink, lavender, purple or golden ribbons that stretch across the horizon. Sometimes clouds with heavy gray eyelids mute first light. Either way all my senses except that of sight are on high alert; a deep peace embraces me in the dark. My body knows the way. I murmur to the willows as I pass through the veil and under their bowed bridge. Their response is muted, a song beneath words.
Tomorrow is Tu B’Shevat, the New Year of the Trees, or their birthday. It is the day of the year when all trees, regardless of when they have been planted, turn another year older. The rabbis standardized this day in an effort to minimize complexities, since in the land of Israel, fruit can only be eaten from trees that are four or older (Leviticus 23-25). Tu B’Shevat, then, on a practical level, marks how old fruit bearing trees are. 
For almost 35 years nature has been my sacred place. As an 8-year old, I started to pray to Mother Earth even though the protestant tradition in which I grew up only recognised ‘God the Father’. I went outside in my inflatable rowing boat to seek solitude (as an only child in a quiet family!) on a small island in the lake of our local park. I practised rowing and walking quietly to not break the sacred silence. I collected herbs to brew infusions in my little thermos flask with boiled water brought from home. I sung to the moon, and danced my love for all creation back through my moving body. Over the last 15 or so years, I spent many days and nights at Neolithic monuments, dreaming in ancestral burial mounds, time traveling in stone circles in Cornwall, Wales, Scotland, England, Ireland and Brittany. This nature-based practice evolved naturally, and later incorporated my training with the Scandinavian Centre for Shamanic Studies and the School of Movement Medicine. Nature is where I reconnect most easily with the Sacred, and listen to the whispers on the great web of life in which all of nature is a great teacher. Nature, for me, is a strong place of prayer, solace, awe, reverence, gratitude, joy, guidance, reconnection, healing and transformation.

This morning the sky was on fire before dawn even as I approached the river whose ripples reflected a purple so deep it was almost inked in charcoal – In the Bosque I noticed that one mule deer had used a juniper to scrape his antlers. Otherwise the Earth emanated precious predawn stillness except for the sound of receding river waters slipping over cobbled stones. It was mild; I thought today might be the day…
