Project Description

Case Study 5: Survey of Fauna Diversity and Geomorphology, Yarra Valley Ranges, Victoria, Australia

The Yarra Ranges National Park was created in December 1995, and spans 76,003 hectares within Victoria’s Central Highlands. This National Park has been given “the International Union for the Conservation of Nature (IUCN) Category 2 (National Parks) of the United Nations List of National Parks and Protected Areas”. By being category 2, it means that the park is primarily managed for the ecosystem conservation and appropriate recreation within it. The park is made up of wet Mountain Ash Forest and Cool Temperate Rainforest,as well as a diverse range of flora and fauna species.

 

This project examined the influence of downstream shifts in geomorphology upon the density and aggregation of select invertebrate egg masses along the upland rivers of Yarra Valley, Victoria, Australia. A trend between emergent rock density and invertebrate egg masses was established, which suggests that local processes affect the larval and adult stages of stream insects independently, and at different scales. This must be taken into account for effective management of the river’s freshwater ecology.

 

This project was greatly aided by our friends and colleagues, Dr. Barbara Downes, Dr. Jill Lancaster and Dr. Phil Marren.
