Leaves: Evergreen needles are to 1-inch long with bracts at the base. Height can be approximately 100 feet, with a trunk diameter to 30 inches. Higher up in the subalpine it's found mixed into the forest on warmer south facing slopes. BARK: Cone scales much thickened and tipped with a strong, curved spine. Characteristics: Many Douglas-fir are straight Christmas-tree shaped trees with relatively dense foliage in crown. The black spruce, the narrowest conifer, ressembles a cylinder more than a cone, whereas the white spruce is wider and is shaped more like a cone. Structure of Forest. The conical shape of conifers prevents as much accumulation as there would be on a wider shaped tree. Having a conical shape is especially useful for receiving sunlight that comes from a steep angle at these high boreal latitudes. The conical shape of the tree also helps to get the snow to fall off the tree quickly. Winter can damage trees with too much snow accumulation on a tree causing it to break off and fall down. These hardy trees survive the most grueling weather conditions where they survive in the subarctic tundra. It can be distinguished from lodgepole pine mainly by difference in form and shape of the needles and cone characteristics.

The perfect pyramid shape of spruce trees is one reason why these are popular Christmas trees . Location: Longleaf generally grows in very sandy soils. Wood and Uses Wood is moderately heavy, soft and nearly white in colour. It is now recognized that so-called climax communities in the boreal undergo an approximately 200-year cycle between nitrogen-depleting spruce-fir forests and nitrogen-accumulating aspen forests. Although these fungi are most common in the ecosystems we list them in, many Spruce trees grow in a similar shape to fir trees and they are difficult to identify by shape alone. By asking yourself these kinds of questions, you will begin to see the different silhouettes. When young, the seedlings pass through a "grass" stage for a few years in wwhich the stem grows thickness rather than height and the taproot develops rapidly.
