Platypus Population Assessment - Broken Creek

This report is to help the GBCMA develop an informed and sensible plan for managing the platypus population in Broken Creek over the longer term, by (1) providing an overview of the distribution and regional significance of the Broken Creek platypus population, and (2) suggesting some management options that could be implemented to help protect the population.

Introduction to the Riparian Restoration Experiment

The restoration of riparian zones is being carried out across streams throughout Australia, costing millions of dollars annually. These efforts are motivated by an understanding that the overall health of our streams is intimately linked with condition of the riparian zone. However, the magnitude, rate and timing of ecosystem recovery once restoration activities have commenced is far less certain.

There is also a need to better understand the specific mechanisms involved in recovery and the key factors that might indicate success. In most cases the responses of a stream to riparian rehabilitation are not monitored, and where monitoring is conducted no consistent methods are used. With the support of the Murray-Darling Basin Commission, and CMA's, a team of scientists are addressing this knowledge gap. The project is called the "Riparian Restoration Experiment".

Broken River and Broken Creek, Monitoring Native Fish

Knowledge of the status of native and introduced fish communities is important in managing natural resources. This knowledge is required to make decisions about whether management actions (e.g., habitat rehabilitation or increased fish passage) are required and what needs to be implemented to provide desired outcomes. The existence of baseline and continued monitoring is also vital to investigate the effects of management actions.

In the Broken Creek a study was undertaken between Nathalia and Numurkah to:

• collect baseline fish data;
• assess upstream fish movement as a continuation of the lower Broken Creek fishway program; and
• identify areas with the potential for habitat rehabilitation.

In the Broken River a study was undertaken upstream of Shepparton to:

• provide information on the distribution, diversity and abundance of fish and;
• establish whether instream barriers continue to restrict fish movement.

Mid Goulburn River Health Report

The Goulburn Broken Catchment Management Authority (GB CMA) contracted Charles Sturt University's Institute for Land, Water and Society (ILWS) to explore landholder and wider community values, perceptions, priorities and actions in relation to management of the riparian zone of the Mid-Goulburn River. This research was intended to support the implementation GB CMA's Regional River Health Strategy.

The research team had previously conducted similar research in the GB CMA region in 2001 (Curtis et al. 2001). These data provided an important baseline against which to compare changes over time in aspects of landholder management of river frontages.
