Prioritising the value of information for the management of Moira Grass (Report now available)

We have led a value of information project to help managers of Moira Grass determine which information should be collected as a priority. The team worked very closely with domain experts to design and complete this project. Our findings indicate that management strategies targeting grazing (61% increase in total extent; 46% increase in Moira grass cover; 42% increase in thatch depth) and flood duration and depth are most likely to improve the restoration of Moira grass at the Barmah Forest (See Executive Summary below for more information).

We have learned a lot during this project on the strengths and weaknesses of Value of Information. We will aim to publish these lessons learned in the academic literature.

Executive summary:

Barmah Forest is a Ramsar listed wetland complex in the Murray–Darling Basin of Australia. Barmah Forest supports the largest area of Moira grass (Pseudoraphis spinescens) plains in the Murray-Darling Basin and is amongst the most southerly distribution of the species in Australia.

The plains are recognised as part of the Ramsar ecological character description of the forest. Reduction in the area of Moira grass plains has been one of the most significant long-term ecological changes within the forest. The causes of decline are uncertain Read more

Riparian restoration mitigates impacts of climate change

Chrystal Mantyka-Pringle (CSIRO postdoc in the team) worked in collaboration with the University of Queensland, Griffith University and the Queensland Government, to better understand the combined effects of climate change and land-use change on freshwater biodiversity. Read more

About

The Conservation Decisions team (CSIRO Land and Water) is a multi-disciplinary group with expertise in ecological modelling, systematic conservation planning, ecosystem services, applied mathematics, artificial intelligence, and decision theory. We’re pioneering techniques in optimal resource allocation, cost-effectiveness analysis, expert elicitation, value of information, multi-objective optimisation and adaptive management. We apply our expertise to diverse problems to inform the recovery of endangered species, management of pests, invasive species and diseases, design of conservation reserves, medical decision making, freshwater resource management and the prioritization of threat management to conserve biodiversity in a rapidly changing world. We solve pressing global decision problems. We do this by connecting big and small data with decision science to determine what actions to take, when and where to get the best outcomes for our bucks, while taking into account the many other competing needs of society.
