Addressing feed supply and demand through total grazing pressure management

Total grazing pressure (TGP) influences the demand for forage by all grazing animals (both domestic and non-domestic) relative to forage supply. Successful rangeland management relies on managing grazing pressure from non-domestic herbivores, adjusting livestock numbers in response to available feed and strategically resting pastures. A central tenet in TGP management is achieving the balance between supply and demand for feed, and avoiding an imbalance occurring when feed demand exceeds feed supply. This imbalance can be detrimental to livestock productivity and animal welfare and damage resource condition.

Despite the past R&D in TGP management and the recent uptake of exclusion/TGP fencing across some areas in the Southern Australian Rangelands there is a gap in knowledge for viable TGP management options for maintaining or improving livestock production and resource condition. In addition, there is an inability to identify when an imbalance between feed supply and demand occurs. Industry knowledge and technical expertise is currently fragmented across different jurisdictions preventing the sharing of information. This current operating environment of the Southern Australian Rangelands is precluding the capacity for industry to make informed decisions about cost effective, practical solutions for TGP management. An inadequate understanding of TGP management solutions is preventing sustained productivity growth and threatens the pastoral industries ability to adapt to climate variability through the effective management of all herbivores.

This project used a coordinated approach at the national level to capture common issues in TGP management. It was undertaken as a partnership between four states (Queensland, New South Wales, South Australia and Western Australia). This ensured national and regionally relevant information and context was captured on TGP impacts, opportunities and management and to identify key knowledge gaps, providing an opportunity to deliver production gains to more than 1.9 million km2 of Australian rangelands.

A key feature of this project was to ensure a synthesis of information drawn from science and practice. Consultation at the regional level was undertaken to capture local knowledge through a formal industry and stakeholder survey (n=266) across the Southern Australian Rangelands. The project design was able to identify existing and new regional producer networks, scientists and extension agencies to identify a community of practice to support future MLA Research, Development and Adoption (RD&A) in TGP management. Our approach aimed to strengthen the ability for MLA to target RD&A investment with the greatest benefits at property and regional scales and outline opportunities for RD&A co-investment.
