Around the globe, natural habitats are being overrun by plant species originating from different regions.

This not only threatens natural ecosystems but also erodes cultural identity and our sense of place, says the author Professor Len Gillman. Due to the widespread planting of foreign species, plant landscapes are becoming increasingly indistinguishable among regions and countries.
