Ailanthus altissima: "toxic tree of heaven"
In article , "Des Higgins" writes: | | It is actually undoing millions of years of evolution by letting species mix | willy nilly. In some places, yes. In the UK, not really. There are a mere handful of plants (and PERHAPS two land vertebrates) that have survived from 11,500 years ago. All of the rest have colonised or been introduced by man (and we don't really know which, in most cases). It is true that introducing plants from outside western or northern Eurasia 'undoes millions of years of evolution', but that applies to fewer plants than most people realise. It doesn't apply to Rhododendron ponticum, for example. Regards, Nick Maclaren. |
