Wet and dry

An important concept to understand about many inland wetlands is that they have a wet and dry cycle. Both are important to the health of the wetland and both can last for months or even years.

The plants and animals are well adapted to such conditions. Most wetland plants have resilient seeds or spores which lie dormant in the dry ground waiting for the next wet cycle. Reeds have underground storage roots called corms from which the reeds re-shoot after fire or drought. The two dominant eucalypts, the River redgums and Coolibahs, produce flowers and seeds which germinate following wet cycles. The mature trees however can survive long dry cycles.

Frogs, tortoises and yabbies dig themselves deep into the mud and are dormant until the next wet cycle.
