![]() ![]() The story of the roach is a good example. Mink, zebra mussels, Japanese knotweed, roach, gunnera, New Zealand flatworms, to name just a small selection.īut there is a shortage of hard scientific evidence showing large scale environmental or economic damage resulting from these ‘plagues’. There have been many horror stories about invasive species in this country in recent decades. ![]() This is all very interesting and it’s relevant to conservation in Ireland. He goes further and suggests that many of the horror stories about invasive aliens are invented by scientists trying to raise research grants to study the species in question. He sets out to show that this is not only largely untrue, the reality is the we are often confused about what is native and what isn’t (which is the point of the question about where camels belong). This assumption is reinforced by the fact that the adjective “invasive” is often attached to alien species. One of these assumptions is that “native” species are always good and “alien” species are always bad. Dr Ken Thompson is a fine scientist, but he revels in attacking some of the more complacent assumptions of orthodox science. ![]()
