Treeshave been growing on our planet for about 390 million years, in what is called the Middle-Late Devonian period. Those trees did not look much like the trees in our woods today, but they did meet a definition that paleontologists use describing a tree as a plant with a single stem that can attain larger heights because they have specialized cells. Trees were small back then.
Nowadays we know how big the family of trees has become, and how big the trees have become. As recently as 2006 a coast redwood, Sequoia sempervierens, was discovered growing in Redwood National Park in California by two naturalists, Chris Atkins and Michael Taylor. That newly discovered tree was measured at 379.7 feet. It was forest ecologist Steve Sillett who climbed to the top of the tree and dropped a tape to the ground. A very long tape measure. To prove it we can all go to the National Geographic website or You Tube and search for Steve Sillett Redwoods and see the film.
In ancient times, when people depended on agriculture and the forests for sustenance and shelter, they knew the names of the different trees. They created relationships between trees. The Celts considered that the oak, ash and thorn made up a sacred trio with powers to heal.
Massachusetts has its share of ash trees. We had a row of ash trees on the road to our house in Heath. We saw lightning scars on their bark, proving their power to attract lightning. As a practical note, both ash and thorn, make good, hot, burning firewood.
Finally, the third of the sacred circle, the thorn. We use the full name, hawthorn. This tree, Crategeus, is known for its large sharp thorns. However, C. viridis, Green Hawthorn, has few thorns. You can see these thornless trees locally at the Energy Park. The Greeks and Romans associated the hawthorn with weddings and babies. Brides and their attendants carried hawthorn blossoms. These trees were often planted by holy and healing wells in England. Homeopaths consider the hawthorn a powerful medicine and use it for heart tonics.
There are many ancient stories about the trees that are familiar to us, like the oak, ash and thorn. However, when we talk about trees today, we talk about their beauty and value to the environment. Trees breathe in carbon dioxide and breathe out oxygen. In forests tree roots help rains seep into the ground where they are taken up into the tree and then release that filtered water as vapor and oxygen. Trees also cool our neighborhoods and cities because of the shade they throw and because their transpiration of water also cools the air. We can treasure parks with large trees and leafy canopies that shade us and cool us during the summer.
During our first winter in Heath the heavy snows blew and fell on our road, sometimes making it impassible, even for the town plows. During our first spring we began to plant our windbreak. We planted several varieties of conifers in three staggered rows alongside the road to catch the snow. This kept our road from being a giant snowbank. The town crew appreciated it.
