Fears brumbies are contributing to blue green algae in NSW Kosciuszko National park

There is concern wild horses in Kosciuszko National Park are contributing to blue-green algae in dams and streams in the New South Wales Snowy Mountains.

Colin Sinclair has been fishing in the high country since the 1960s and said he has only seen blue-green algae the area in the last five to seven years.

He said it is not killing fish, but is visible.

Mr Sinclair attributes the blue green algae to very high summer temperatures, especially over the 2018/19 summer, and questioned whether brumbies are enhancing the bacteria in the water.
