context1: Its breeding habitat is marshes and <strong>lakes</strong> in sub-Saharan Africa. They build a floating nest in marshes and <strong>swamps</strong>, laying 2-5 eggs. This species is partially migratory, undertaking seasonal movements.
context2: The landscape to the east and west of the river is also remarkable. Peat extraction in the 17th and 18th century turned vast low-lying fens into a collection of shallow, man-made <strong>lakes</strong> and bogs. Water lilies, reeds, <strong>swamps</strong> and wooded areas have developed spontaneously from the old peat canals (trekgaten) where the peat was extracted.
