15187: Onground action protecting the aquatic biodiversity of the Margaret River

    The river pools of the upper Margaret River are one of the most important aquatic habitats in south-western Australia due to their exceptionally high proportion of threatened aquatic fauna. This environment is under increasing threat from invasive species and reduced streamflow. 

    This project undertook an on-ground, strategic approach to protect the critically endangered Hairy Marron (Cherax tenuimanus) and threatened native fish species including the Balston's Pygmy Perch (Nannatherina balstoni) and the Western Mud Minnow (Galaxiella munda). The project included continuation of successful 'fish downs' of introduced Smooth Marron (Cherax cainii) and a control program focusing on the introduced Eastern Gambusia (Gambusia holbrooki). The project activities were delivered by contractors under the supervision of CCG staff and assisted by local volunteers. Volunteers were selected from those trained as a local Hairy Marron Volunteer Team during previous fish down activities and to further increase the skills and knowledge of this team.
