REGENERATION of degraded areas in regions of marginal rainfall is a slow process under the best of conditions, but on the Ord River Catchment, where much top-soil had been removed, the problem was unusually severe.
In many areas top-soil will have to be rebuilt before vegetation can be re-established.
This will be a long, slow process and regeneration will proceed through gradual plant succession from the "pioneer" annual species through to the permanent and more productive perennial species needed for a stable catchment area.
