 Though it can grow up to 5 metres in height, when managed for grazing it is kept to less than 2 metres in height.On the poor white sands in Western Australia tagasaste has increased the animal carrying capacity from 1 to 2 dry sheep equivalents, with annual pastures to 8-10 dry sheep equivalents (~ 1 cow) per hectare with mature tagasaste.This is roughly a tenfold increase in soil fertility-based carrying capacity.
