Lewis at woodlands.co.uk tells us about the exotic (alien) trees which are familiar in our British landscapes. Lewis tells us how many of these trees arrived during colonial times when great houses and gardens were built. He doesn’t mention how much of that wealth arose from sugar cane plantations in hotter climates than our own, worked by slaves.
Being a set of islands, it’s no surprise that we have alien trees. Many have become naturalised here. Many are beautiful. Many form part of our hedgerows, many produce timber. Some have become invasive, disrupting ecosystems and spreading diseases.
