Water Vole has been skating on very thin ice in the UK for a number of years. You and I know him as Ratty from Wind in the Willows but a rat he is not. Scarce, yes: rat, no.
In fact conservationists warned a decade ago that very soon there would be none left – extinction within the British Isles was it seems a done deal. However, the water vole has made quite a comeback in several areas, thanks to environmentalists and not least its own remarkable fecundity. The Ark in Space reports on this happy tale from the riverbank.
