Issue 4 Controlling Lippia: the Role of Environmental Water

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.

Issue 3 Waterbirds in the Gwydir

To the west of Moree the land gets flat, very flat. So flat that the Gwydir River disperses into several channels and flow paths, forming the Gwydir wetlands. These wetlands support some of the largest breeding colonies of waterbirds in Australia and include areas that are listed as Wetlands of International Importance (Ramsar convention).
