Brief_description
Farm dam with fringing reeds and formerly up to 25% cover of floating alien Parrot-feather Myriophyllum aquaticum. Attracts a reasonable selection of waterbird species, none in large numbers; commonest species in summer are Egyptian and Spurwinged Geese, and Blacksmith Plover; in winter Cattle Egret, Yellowbilled Duck and Redknobbed Coot; small numbers of Ethiopian Snipe occur in summer. Decline evident in number of species and total counts; reason suggested (G. Lamont) for this is recent removal of Parrot-feather manually, and of this and other fringing water plants by herbicide. Although Parrot-feather normally considered a threat (e.g. see Paarl Sewage Works), observations at Klavervlei suggest it may attract birds by providing cover and harbouring invertebrate food. African Jacana no longer occurs but was formerly seen on Parrot-feather, as was single Baillon's Crake; Ethiopian Snipe, Black Crake, Purple Gallinule, Moorhen and Redknobbed Coot were probably attracted to it, and any unusually high numbers of Spurwinged and Egyptian Goose and Yellowbilled Duck tended to concentrate among it.
