Effect of Hydroelectric Power Development
Since the Black Stilt nests on the braided rivers beds of the South Island, it is threatened by changes in river flows as a result of new hydro dams and changes in flow regimes for existing dams.
The Upper Waitaki Power Development posed a threat to the habitat of the black silt. A program was set up to lessen this threat. The Black Stilt population on the river beds varies with the river level. Changes in the level of Lake Benmore, which caused corresponding changes in the deltas of the incoming rivers, affected the local population of Black Stilts.
