Info

The catchment is located in the Mpumalanga and Gauteng provinces, and species protected in both these catchments have been included. Species referred to as protected in this section are species protected according to the Mpumalanga Nature Conservation Act (Act no 10 of 1998) and the Gauteng Nature Conservation Ordinance (Ordinance 12 of 1983). These species may not be killed, removed, moved or disturbed in any way without permission from the Mpumalanga Parks Board or the Gauteng Conservation Directorate. The distribution ranges of some of the species were included in a separate shapefile. The distribution of the mammal and bird species was based on museum records. The quarter degree grids in which the species were recorded were noted and the possible occurrence of the species was based on these records. Where a species was observed in a number of quarter degree grids close together it was assumed that the species can also occur in the grids located between the recorded occurrences. It should also be taken into account that the museum records indicate historical location and that the habitat for the species may have been destroyed in the past. The species mentioned in each of the quarter degree grids are therefore only a possible indication of the species distribution. Inclusion of a species in a grid does not insure that the species occurs in the grid and exclusion does not ensure that it does not occur in the grid. Wetland Database for UORC - 18 -

Occasionally forages along sandy coasts. Usually breeds colonially on mudflats in large pans. Fast-flowing perennial streams, rivers and estuaries, usually with dense marginal vegetation. Usually perches low down on the banks of streams, often on exposed roots. Requires riverbanks in which to excavate nest tunnels. Midland and highland grassveld, edge of karoo, cultivated land and edges of vleis. Nests in both moist situations in vleis which have short grass cover and in dry sites far from water, usually exposed places such as on hillsides; forages in grassland, cultivated and fallow lands; roosts communally in the shallow water of pans and dams.
