I'm awaiting more articles from Dr. Petty.
As I think I mentioned in an earlier email the NT Government has declared
that Gamba grass is out of control from Darwin to Katherine. They are
fighting a rear guard action trying to prevent it moving further south. The
situation may have been made worse by the loss of Indigenous rangers from
key parks - they tell me that weeds were under control before they resigned,
but not now.
