Western Red Cedar – Biodiversity   Western Red Cedar does not grow in pure stands – it shares the forests with a huge range of other species. The forests are home to roughly two thirds of the 140,000 species of plants, animals and invertebrates estimated to occur in Canada.     Forestry companies achieve biodiversity through specific reforestation:         #  Using native species.       #  Following the classification system.       #  Avoiding genetic engineered products.       #  Applying the latest science.      Native Species In order to retain the natural biodiversity of each forest region in Canada, harvested areas are regenerated with native tree species. More than 30 different species of trees are planted in the various regions to ensure that reforested areas are as diverse as the forests that were harvested.   Classification System British Columbia has developed a classification system that allows resource professionals to base decisions on detailed information about climate, soils and characteristic vegetation in each of 14 unique ecosystem zones. In the past, it was not uncommon to log Sitka spruce or hemlock and replant the harvest area with Douglas-fir because of its higher commercial value.   Genetic Engineering British Columbia does not use any genetically modified or genetically engineered trees. Its seed and seedlings come from natural wild stands or seed orchards that promote desirable traits from natural stands.   Applying the Latest Science Where forest companies were once encouraged to clean up harvest areas, forest professionals know that debris such as the stumps, branches and fallen trees left on the forest floor after harvesting are critical to manage biodiversity. They provide habitat for plants, animals and insects, and a source of nutrients for soil development.
