Abe Bailey Nature Reserve, Protected area in Gauteng, South Africa.

Abe Bailey Nature Reserve is a protected area near Carletonville in Gauteng combining wetlands, bushveld, and grassland habitats. The landscape includes several zones that visitors can explore along walking trails through different ecosystems.

The reserve is named after Sir Abe Bailey, the South African mining magnate and politician, and lies beside Khutsong township on the West Rand near Carletonville. The sources record no founding date or founding organisation, so its early administrative history is not documented here. It now falls under the Merafong City Local Municipality in Gauteng and covers about 4,200 hectares.

The reserve takes its name from Sir Abe Bailey, the mining magnate and politician who funded its purchase; the land lies beside Khutsong township on the West Rand. Birders gather at the wetland each year when thousands of flamingos stop over for a few weeks, and the reserve is one of the few recorded breeding sites of the yellow-billed stork outside the Okavango Delta.

The reserve lies beside Khutsong on the West Rand, near Carletonville, and covers about 4,200 hectares, so allow time to move between the wetland and the highveld grassland. The wetland attracts thousands of flamingos for a few weeks a year, and the osprey is a summer visitor, so timing a visit to those seasons matters.

The reserve's wetland is one of the few places outside the Okavango Delta where yellow-billed storks have been recorded breeding. Thousands of flamingos also gather there for a few weeks each year, and the summer-visiting osprey and African fish eagle are regularly seen.
