Controlling lippia: the role of environmental water
An abundance of water couch (Paspalum distichum) - at a vegetation survey site near Bunnor wetlands.
Lippia (Phyla canescens) is a significant weed in the Gwydir wetlands. It spreads along the ground smothering native grasses, reducing both our native habitat and our natural pastures for cattle. Water couch and lippia tend to live in the same areas. What we have found is that the delivery of environmental water can benefit water couch, allowing it to dramatically out compete the lippia weed.
