​​This study explored the ability to develop reference curves to describe exemplar age class distributions for key floodplain tree species. ​ ​​Understanding the characteristics of tree populations, such as their density, age structure, rates of recruitment (germination and establishment of new trees), growth, and mortality (death rates), are important to understanding the likelihood that tree populations are sustainable. This includes understanding the role of these processes on age class distributions. Developing reference curves – tools that help to define the acceptable limits of parameters such as age class distributions – helps us to determine the likelihood that tree populations are sustainable or may require management intervention to promote recruitment or old growth for example. ​

The Murray–Darling Basin Authority (MDBA) has today released its Constraints Relaxation Implementation Roadmap to guide governments in delivering projects that will maximise outcomes from environmental water use across the Basin.

In the Murray–Darling Basin connectivity amounts to one single idea, continuity of river flows. Delivery across the vast territory of the Basin will involve another kind of connectivity, of government with communities.

It’s not the most exciting name, but the Constraints Relaxation Implementation Roadmap is an important body of work being developed this year by the Murray–Darling Basin Authority (MDBA).

Sustainable diversion limits are how much water, on average, can be used in the Basin by towns and communities, farmers and industries.

The Murray–Darling Basin Authority (MDBA), in collaboration with state and Commonwealth governments, is working to deliver a Constraints Relaxation Implementation Roadmap.

The research focused on improving understanding of low flow requirements of environmental assets and values in a climate change context and developing a conservation prioritisation method to identify priority locations for future management decisions.

The MDBA was at the Riverina Field Days recently to share with, and learn from, the local community.

Food Next Door Co-op and local water owners support Mildura’s landless migrants and refugees to do small-scale regenerative farming.
