THE ASPEN POPLAR (Populus tremuloides) The Aspen, or White Poplar, is often called trembling aspen because its leaves have flat stems which enable them to turn and twist or "tremble" in the wind. (The Aspen Poplar grows rapidly, as much as five feet in a year so its wood is very loose-textured and rather weak. It has a very wide-spread root system and spreads rapidly by means of shoots or suckers which arise from the roots, just below ground level. This type of reproduction is especially noticeable after disturbance such as fires. The Aspen's roots can live through all but the hottest fires. The newly produced suckers rapidly fill in any open spaces that remain after the fire. The young Aspens quickly outgrow the shrubs and other vegetation around them and gradually take over the area because of the shade they cause. The bark of younger Aspens is usually a yellowish-green color. The green color indicates the presence of food-producing cells right at the surface. Aspens frequently have a chalky, whitish film on their bark, especially in winter. This film is usually whiter and thicker on the south side of the tree. The white surface serves to protect the food making cells from being heated up during periods of intense sunlight an warmer temperatures, which often occur during winter mild spells. The extra whiteness on the south-facing side helps to reflect, instead of absorb, the sun's rays. Should the food-making cells warm up too much they will start becoming active and then, when the sun goes down and frost occurs again, they would be destroyed. In a series of dry years, Aspen groves have a tendency to recede from their edges as the grassland around them competes for water. In wet years, Aspen groves may expand. Their rapidly-spreading shoots may outgrow both shrubs and grasses and eventually shade them out.
