The Tree of Heaven has the potential to seriously damage the biodiversity of Britain, and we only have to look at Japanese knotweed to see the consequences. Brought over in the 1700s, Japanese knotweed is the UK' s bestknown invasive plant, it wreaks havoc with our wildlife, and our infrastructure. It seems that the Tree of Heaven is set to do the same. Like Japanese knotweed, it' s spreading out from London as its seeds are blown along our railway lines. So what does this mean for the future of the landscape of Great Britain? Very, very significant changes, I expect. These nonnative organisms moving into our landscape mean massive change. We' re going to see a landscape that' s going to have fewer species in it, many of them will be incredibly successful but it will be at the cost of many many other things. And that loss of diversity will have a real impact on us and our wellbeing, because speciesrichness is massively important for all of us and for our agriculture. |
