Oct 1, 2024 · Forest regions are geographic areas with similar dominant tree species. Forest composition classifies trees by genus. Plant hardiness zones indicate where plants are best suited to the climate. Canada’s forests are classified in four main ways: ecozone, forest region, forest composition, and plant hardiness zone.
The majority of dominant and codominant trees are Douglas-fir, while the intermediate and suppressed trees are primarily shade tolerant western hemlock. Therefore, healthy trees in the small diameter classes (6-10 inches) may survive over time, even though they are surrounded by large trees.

Jun 16, 2022 · To define “predominates”, it means that the species prevails or is superior over the other species in terms of numerical advantage or control. For example, in wet woodland in western Europe, the dominant tree is alder (Alnus glutinosa). Some seafloor communities are dominated by brittle stars.

5 days ago · A forest is a complex ecological system in which trees are the dominant life-form. A forest is nature’s most efficient ecosystem, with a high rate of photosynthesis affecting both plant and animal systems in a series of complex organic relationships.

In general, LCR will reflect crown class, regardless of species. Trees growing in the dominant crown classes tend to have the longest crowns overall, followed by trees in the codominant, intermediate, and suppressed crown classes respectively (Table 5.3).
