Issue 41 Species Benefits of Widespread Inundation in the Gwydir Warrambools

Hydrology is the study of when, where and how galie (water) is delivered into a bagaay (river) channel, floodplain or warrambool (wetland). The Long Term Intervention Monitoring and Flow-MER projects have tracked natural flows and releases of Commonwealth water for the environment into the Gwydir River since July 2014. This delivery of galie directly impacts galie quality and through this defines the living conditions for aquatic species, including gunambaay (waterbirds) andvegetation.

Issue 34 The Lifecycle of Marranii-maa (Dragonflies)

Did you know that there are over 300 species of dragonfly in Australia? These species are divided into eight families, two of which (Hemicorduliidae and Aeshnidae) occur within the Gwydir Wetlands State Conservation Area. We study these as part of our Food webs indicator because they can tell us a lot about the health of our waterways. In Issue 34 we explain the importance of invertebrates and the dragonflies lifecycle.
