Hi! Tony, It is not all, but some specific Eucalypts. Some of the Mallees - these are multi-trunked trees that grow from a lignatuber, which is the famed "Mallee Stump", the preferred fire wood in the drier areas. In my area the Sugar Gum, E. cladocalyx, will allow no pasture grasses to grow under them, but some native grasses will. The is some times used in property planing and management. A strip of mallee a chain or so wide will stop most weeds invading, while a stand of sugar gum can form a fire break for grass fires.
