Red Squirrel Population

I am grateful to my hon. Friend for attending the debate, because, as I well know, the Isle of Wight is an important reservoir of red squirrels. It is fortunate in being separated from the mainland by a stretch of water, which I think is why red squirrels have been saved there. The grey squirrel was introduced in the 19th century as an ornament to estate gardens. No doubt that was thought to be a good idea at the time, but since then the grey squirrel has spread and now it is causing or is likely to cause an environmental disaster for our native red squirrels. The issue of alien species has come to the fore in recent years. Throughout the world, there are a number of examples of what we have seen happen in this country. Apart from the grey squirrel, we have the American mink, which has caused considerable damage to our rivers, and foreign fish and shellfish species have also been introduced. Not the least among the vegetation that has been introduced into this country is the humble rhododendron, which many people admire hugely. One admires rhododendrons when one sees them in formal gardens, but in parts of the west of Scotland, as I am sure the Minister knows, they are spreading and causing great problems. The problem of alien species is not unique to the UK; it occurs all over the world. The Australians are trying to eliminate European foxes, which were introduced to develop fox hunting in Australia. That puts me in a slight quandary, as I am rather fond of fox hunting, but I can understand the reasons for what the Australians are doing, because European foxes have done a lot of damage in that country. In another example, the New Zealand authorities are making a substantial effort—quite successfully, I believe—to eliminate the possum from the New Zealand countryside.
