From MARK EDWARDS
My photograph showing dead trees and the effects of salinisation did
not match your caption, which said that trees had been planted to turn Australian
salt lands back into productive use. (In Brief, 9 February). You should
have used my picture that showed live trees planted by Alcoa, as part of
its Land Care programme. The trees ring the affected land, lowering the
water table and cutting the flow of salt to the surface.
