The Overberg Crane Group works to protect Blue Cranes and other threatened big birds in the Overberg, Western Cape of South Africa. The Group was launched in 1991, when Blue Crane numbers declined rapidly, partly as a result of poisoning. Today around 25,000 Blue Cranes remain in the world - most of them living in the Overberg. In 2014, the Overberg Crane Group changed its Constitution to also protect other threatened big birds, like Secretarybirds, Denham's Bustards, Korhaans and a number of raptors. The Group works to protect these birds by ensuring their habitat is protected, by collecting data and information on numbers and population trends, and by raising awareness with key stakeholders and partners, like landowners and other important players.
