It is also part of the Lee Valley Ramsar Site and Special Protection Area, and is owned and managed by the Hertfordshire and Middlesex Wildlife Trust.〔(【引用サイトリンク】url=https://rsis.ramsar.org/ris/1037 )〕 The site is a former gravel pit, which has been restored to become a wetland nature reserve with two lakes, Great Hardmead Lake and Hollycross Lake. It is internationally important for wintering wildfowl, and is Britain's most important site for dragonflies. It also has large communities of damselflies and breeding birds. Plants include marsh dock and hairlike pondweed, both nationally rare. Amwell has a quarter of all British species of molluscs.〔(【引用サイトリンク】title=Amwell )〕〔 There is access from Amwell Lane and the site is open at all times.〔 ==See also== *List of Sites of Special Scientific Interest in Hertfordshire 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「Amwell Quarry」の詳細全文を読む スポンサード リンク
