Brief_description
An IBA and part of the Blesbokspruit Ramsar site. Has extensive Phragmites and Typha reedbeds, also sedgebeds, wet grass, and open water with floating-leaved vegetation. Good numbers of Glossy Ibis, Yellowbilled Duck and Redknobbed Coot occur all year; Squacco Heron may be quite common in summer. Hottentot Teal and Spurwinged Goose numbers peak in winter. A good selection of rails occurs, and Spotted Crake is also recorded. Purple Heron, Little Bittern, Grass Owl and Marsh Owl also occur. Increases are apparent in the number of species (summer and winter) and total count (summer). Blesbokspruit is severely threatened by discharge of mine water which drastically increases total water volume, maintains artificially high water levels in the dry season, and contains many pollutants, including salt. The CWAC site known as "Marievale Area B" is the area opened up due to the spraying of the reed beds to manage the the reed encroachment. This includes sections A, B, C, and D.
