Key facts

• The coniferous forests on the pacific coast of North America were thriving long before the Alps had risen - 20 million years ago.
• The coniferous forest is home to giant redwoods - which grow to over 100m in height.
• The Sequoia Tree is one of the largest living organisms, at 90m tall and 1m thick, and it can live for over 3000 years.
• In the mid-19th century, the coniferous forests attracted loggers and the redwood were reduced by 90%.
