"Non-Native" Plants Are Usually No Worse than Others

professor Mark Davis on invasion biology

doc-titleImmigrant species aren't all bad
quoteHumans have been transporting species around the world, intentionally and unintentionally, for centuries. Many of the species we think of as a natural part of our landscape are, in fact, non-native. For example, the honeybee, which nearly a third of US states have named as their state insect, was introduced into North America from Europe in the 1600s. ... Whether we like it or not, the world's biodiversity is becoming globalised. We can call them aliens, exotics or biological pollution, but the fact is that introduced species are our new residents.
