The Greenery of Winter

As we approach the winter solstice, much of the Temperate Zone landscape appears to be lifeless.  Brown, dry grasslands, barren deciduous trees and leafless thickets dominate the scene while the refuse of the growing season blows across our fields and lawns.  Fortunately, an exception is provided by the conifers, the evergreen trees and shrubs that adorn our parks, suburbs, farmlands and forests.

Here on our Littleton farm, we have a mix of conifers, including junipers, pinon pines, Austrian pines and a few spruce trees.  Providing greenery during the winter months, they also attract a wide variety of birds that utilize their shelter and feast on their berries and nuts.  Among these residents and visitors are red-breasted nuthatches, bushtits, cedar and Bohemian waxwings, pine siskins and other more common species.  The presence of these conifers also increases our chance to see mountain birds that may descend to lower elevations in winter; these include northern goshawks, Steller's jays, mountain chickadees, red crossbills, Cassin's finches and, in some years, evening grosbeaks.

The use of conifers for Christmas trees, wreaths and garlands, stems from the rituals of ancient man, who considered them signs of perpetual life and used them to fuel winter solstice bonfires to coax back the life-giving sun.  Even today, when we understand the solar cycle, the greenery of conifers offers hope through the dark, frigid months of winter.
