Vast forests of pine trees can be found in many different regions, from the snowy mountains of North America to the open plains of Europe. These hardy evergreen trees can grow in environments that many others can’t, favouring acidic or sandy soils and rocky regions at high altitudes.
When exposed to plenty of sunlight, pines can grow up to a towering 80 metres (262 feet) and live for hundreds of years. One bristlecone pine in California is thought to be 5,000 years old, making it one of the oldest trees in the world, but most are cut down long before they reach this ripe old age.
Although pines are native to temperate regions in the Northern Hemisphere, some species have been introduced to southern continents as a valuable source of timber, an industry worth billions of pounds. The young pines that don’t go on to become fence panels and furniture usually end up as Christmas trees in homes across the world. Over 77 million pines are planted for this purpose each year, and take six to eight years to reach optimum Christmas tree size.
However, when left to their own devices, pine trees grow to have long, slender trunks – almost unrecognisable as the same trees we decorate with tinsel and fairy lights – and use pine cones to reproduce. Each tree uses both male and female structures to create the next generation.
