The Island’s Bat Group records roosts and reports on any potential damage. Special sites for these bats include the Briddlesford Copse woodland complex, owned and managed by the People’s Trust for Endangered Species, and the populations found in the Wildlife Trust’s St Lawrence Undercliff Wildlife Reserve. 4. WATER VOLES The water vole is Britain’s fastest declining mammal species yet has a strong population on the Isle of Wight. Although the Island’s river systems are not as rich as Hampshire’s famous chalkstreams, the difference is, there are no mink. This means that the water vole is able to live in less than perfect conditions without being threatened by its non-native mainland predator. The water vole thrives in all the Island’s major river systems, including the River Medina and both the eastern and western Yar. The only threats are poor management of the rivers, which leads to the destruction of its burrows, and the lack of management of bankside scrubs and trees, which can lead to its preferred waterside habitats being left in shade. The Trust has co-ordinated two surveys of water voles with help from the Environment 54 Agency and meets farmers to talk about the management of rivers and riverside vegetation. 5. MARINE MAMMALS The value of the Island is by no means restricted to the land; its seas are home to an increasing diversity of marine mammals. Common and grey seals are commonly recorded, particularly on the Solent shore as they make their way south to the Atlantic. There are dolphins and whales too, although they are less likely to be seen close to the Island’s shore. Harbour porpoise, bottlenose dolphin, common dolphin and pilot whale are recorded most years in Island waters as they come through the English Channel looking for food. Larger whales such as Minke whale and fin whale have also been recorded, more frequently in recent times. The Wildlife Trust runs a Island Life - www.isleofwight.net
