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. The yield of edible dry matter (leaves and fine stems) in the West Midlands is mostly in the range of 3–5 tonnes per hectare. It also prevents the wind erosion and excessive ground water recharge that were major environmental problems before. Recently it has been found that tagasaste can sequester carbon at the rate of about 6 tonnes CO2 equivalent per hectare per year. About half the CO2 being stored is as organic carbon in the soil and half is in the wood of the branches, trunk and roots. Tagasaste typically yields roughly 1 ton of edible material per 100mm of rain per hectare per year.
