But the climate has heated up at an accelerated rate and now it might be more sympathetic to this trees native conditions. It may indeed, but that doesn't mean it will inevitably become a problem here. Over long time spans, you get more and more species and species mixtures evolving that are highly specific to particular locations and habitats and which can do this because they are isolated Then when we come along and mix them with each other you get species warfare and you end up with fewer species as one species replaces others either directly through competition or indirectly through habitat loss/change (e.g. Rhodendron ponticum in SW Ireland are replacing Oakwoods and all the mosses and liverworts that live in them). That is backwards evolution towards the kind of species mix you get in supermarket carparks. Disgruntled of Dublin There are only two sides in species warfare. The human species on one side against which nothing can prevail, and everything else on the other. http://www.patternliteracy.com/exotics.html http://dtheo.org/AABGAPaper.htm http://dtheo.org/NativesVs.Exotics.htm http://dtheo.org/BookOrder.htm Some good points but you completely ignored the point I was making and I can answer all of the points in the above with these: http://www.hoganstand.com/HomePage.aspx http://www.youtube.com/watch?v=0130j5UVpbQ http://www.arachne.com/ http://www.jackiehealyrae.com/ In particular I recommend the sections from the GAA and Jackie Healy Rae; they have comments dotted around their web sites about the effects of aliens on hurling pitches and roadside dancing in Kerry.
