Aqualate Mere is the largest natural lake in the English Midlands and is managed as a National Nature Reserve (NNR) by Natural England.〔(English Nature page on Aqualate Mere )〕 It is a remnant of the prehistoric Lake Lapworth. The Mere lies within the borough of Stafford in Staffordshire, England, some 2 km east〔(English Nature page on Aqualate Mere )〕 of the market town of Newport, Shropshire. It is within the grounds of Aqualate Hall, a country house, with a landscaped deer park. Although large in extent (1.5 km long and 0.5 km wide), the Mere is remarkably shallow and is nowhere much more than one metre deep. Aqualate Mere is an example of an esker system (rare in the Midlands) formed by glacial meltwaters during the late Devensian glaciation, about 50,000 years ago.〔(Staffordshire Regionally Important Geological and Geomorphological Sites Group - Aqualate Mere )〕 The depression in which the Mere lies, thought to be a kettle hole,〔 and the surrounding higher ground which comprises glacial sand and gravel deposits were all formed at the same time. It is fed by streams coming from the north, south and east (including Back Brook), and its outflow to the west forms the River Meese which joins the River Tern, a tributary of the River Severn. The Mere supports diverse fish and bird populations, including large numbers of wintering and breeding wildfowl and breeding Eurasian curlew and common snipe. Together with the surrounding land, it is also important for its botanical and invertebrate communities. Mammals found on the NNR include polecat, water vole and harvest mouse, together with bats such as pipistrelle, Daubenton's, Natterer's, Brandt's and whiskered.〔 Its name came from Anglo-Saxon ''Āc-gelād'' = "oak grove". == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aqualate Mere」の詳細全文を読む スポンサード リンク
