In the 1700 and 1800s old growth white pine forests were harvested and made into masts for sailing ships. So many of these trees were chopped down that even today, only a few survive in isolated forests in Canada's parks and near the northern shores of Lake Superior. Today logging also threatens the magnificent spruce trees all across the taiga biome. These trees are valued for their strong wood fibers, which are used in making high quality paper products. Unless more paper and wood companies turn to manufacturing recycled goods, spruce trees may be gone before we know it.
