Marie, good on you.
Covering pure stands of weed with old corrugated iron and sisalation wipes out both plants and seeds. For single weeds vinegar works a treat – just plain Home Brand vinegar from Coles. I pour about half a cup on the base of the plant. I do hope this is of help to you.

Introduced grasses that keep me busy here trying to keep the integrity of this property at Kobble Creek in SEQ so it stays viable for birds and all other native fauna are Molasses, Rhodes and Whiskey grass.

It’s a battle to preserve a variety of native grasses and herbs for resident birds such as Partridge Pigeon from a variety of interlopers capable at transforming our floristically diverse property to a monoculture. These weeds were mainly brought in as cattle pasture or as contaminants in cattle pasture.

According to a real estate agent properties with gamba grass infestations are not selling. Secondly, and probably a bigger issue for the cattle industry, is another weed, a Rats-tail grass (Sporobolus jaquemontia). The silica in this grass causes a condition called smooth-mouth among stock. Cattle suffering from this condiition have teeth so worn down they cannot feed properly.

Secondly, birds such as Magpie-geese favour the seed and move through the grass stripping the heads as they go. So some granivores may benefit from it, although probably not Partridge Pigeons. They feed in a similar mannter, but only on small grass taxa, such as Eragrostris spp.
