Open woodlands are scattered around the plains, particularly on higher ground and around water. Dominant species include River Red Gums in wetter areas, and Grey Box and Yellow Box in drier areas. In open woodlands, the trees are not overlapping, or very tall, and the understory is made up to grasses and herbs not shrubs. Most of the woodlands have been cleared for agriculture or fire wood. This has caused a decline in habitat for native birds, animals and flightless birds.
