Three native species of poplar grow in Saskatchewan: cottonwood, trembling aspen and balsam poplar. They are fast growing trees that can attain heights of 25 to 30 metres (80 – 100 feet) and a diameter of 100 cm (3 feet) at eye level. The balsam polar is more slender.
Cottonwoods send forth their seeds with tufts of white fluff that form a cottony layer on our lawns each spring. Trembling aspens have flattened leaf stems that allow their leaves to flutter against each other at the slightest breeze. The sap of balsam poplar has a balsam- like scent.
These are trees of the open prairies and boreal forests. Being fast growing trees, they are also short-lived. There is no old growth boreal forest, a 100 year old tree is either a dead tree or a terminally ill tree. Forest fires are nature’s way of renewing the boreal forest, cleaning out the dead trees and the debris from the forest floor and allowing new growth to begin and reach for the sun.
These trees have been widely used in farm shelter belts here in the flatlands, protecting farm yards from the constant prairie winds. But here, as in their natural habitat, they eventually grow old and die. Fires are not a desirable event in a farm yard, so these shelter belts eventually need maintenance. And often don’t get it. The wood from these trees is of little value for lumber, or even for fire wood, providing little incentive to go to all the work needed to remove dead and dying trees. This leads to scenes such as the one I described in my last post.
Several years ago one of these big old poplars could be seen from our dining room window. It was obviously close to the end of its lifespan, one massive branch fell during a summer windstorm. The next spring, most of the branches showed no sign of life, but leaves did appear on a few branches near the top of the tree.
One day, when there was only the slightest breeze, the tree came crashing down. It was easy to understand why when I went to look: the interior of the trunk had rotted until there was not much but bark to hold the tree upright.
I wondered if some Christians might not be like that tree: still upright, showing little signs of spiritual life from the outside, but almost spiritually dead on the inside.
Wherefore let him that thinketh he standeth take heed lest he fall. (1 Corinthians 10:12)
