Weed management strategies that incorporate an understanding of landscape scale ecological processes

Do natural ecosystems benefit from the management of Weeds of National Significance?

Weeds pose a significant threat to natural ecosystems in Australia and consequently large quantities of resources are spent each year to manage them. Amongst these, species identified as Weeds of National Significance (WoNS) are particularly important. The capacity of weed management programs to contribute to biodiversity conservation in Australia has not been comprehensively assessed. This publication is one of a suite of 13 produced as part of a folder showcasing (more)...

Elucidating relationships between disturbance and invasion in riparian zones

This project sought to develop improved riparian weed management strategies by analysing the linkages between disturbance from flood events and both weed invasion and tree recruitment in riparian areas. Analysis of an existing dataset containing assessments of vegetation variables from 23 rivers across Victoria resulted in the development of predictive models relating the number of eucalypt and acacia seedlings at a site to the number of parent trees, the amount of bare ground, the catchment management (more)...

Optimising management of core mesquite infestations in Australia

Mesquite (Prosopis sp) is a highly invasive shrub that forms dense thorn forests in semi-arid and arid Australia. Several mesquite taxa (species and hybrids) are invasive in Australia, with core infestations occurring in the Pilbara, northern Queensland and south-west Queensland. This project team conducted a three-year field study to test whether the invasiveness of mesquite, and its response to biological control, differs with taxa and climate (between region and years).

Developing a model for environmental weed management in fragmented landscapes: A case study

This project is focused on landscape scale weed management in South East South Australia. It is designed to test the scientific merit, acceptability and usefulness of a new integrated planning tool that takes account of the interactions of weeds and natural systems across entire landscapes. The management tool has been developed to assist in prioritising environmental weed management actions based on the risks posed.
