The girdled snail, is it in your garden?
Thames Water is planning to build a massive reservoir near Abingdon in Oxfordshire. It will cover four square miles and contain anything up to 150 million cubic metres of water. Dylan investigated the likely impact of a new reservoir on wildlife. Woodland and hedges will end up under water but nature is surprisingly quick to populate even the most apparently sterile of water bodies.
The National Museum of Wales is eager to track the spread of the Girdled Snail. Native to the Mediterranean it was first spotted in Devon in the 1950s. Since then it has spread as far north as Yorkshire. The Museum would like you to report any sightings so that it can chart the effect of climate change on the mini beasts in our gardens.
