National weed risk assessment of willows in Australia

The National Willows Taskforce has commenced a national weed risk assessment of willows in Australia in order to objectively prioritise willow species, groupings and locations for coordinated control programs at the regional, State/territory and national levels. This process utilises published literature and expert opinion on the biology, ecology and current and potential distribution of each willow.

Given that there are over 300 willow taxa world wide, with a complex variety of species, subspecies, varieties, hybrids and cultivars, it is not feasible to assess the weed risk of all willow taxa individually. We have therefore adopted an objective process to determine which species or groupings of willows will be assessed. This list was developed in consultation with the nursery industry, through communication with willow growers (from Aussie Plant Finder) and the Nursery and Garden Industry Australia's e-newsletter.

Developing willow management priorities

This project, which addresses high priority actions in the National Willows Strategy, was sponsored by the Australian Government Department of Environment, Water, Heritage and the Arts and Department of Agriculture, Fisheries (through the Defeating the Weed Menace Program) and administered by the Department of Primary Industries Victoria on behalf of the National Willows Taskforce.

This extensive resource will assist land mangers in developing willow management priorities by:

determining the current distribution of naturalised willow taxa,
producing risk assessments and interactive maps of the current and potential distribution of all willow taxa present in Australia for state and national planning,
developing a national prioritisation matrix based on risk and feasibility for coordinated control; and
establishing a process for monitoring change across Australia.

National Willows Program Resource Kit

The following 6 resource sheets together form the National Willows Program Resource Kit. The kit provides important information for managers on mapping, willow identification and the willow sawfly.
	This resource kit was developed through funding from the Australian Government's Defeating the Weeds Menace Program for a project titled 'Developing Willow Management Priorities from the Local to the National Level'. The priorities and distribution maps developed for each region and State/Territory through the mapping and weed risk assessment components of this project will be posted at this site by March 2008. See Resource Sheet 1 for details on how you can become involved in this important project.

A tribute to the late Kurt Cremer

Willow infestation in our streams and rivers might not have been recognised as such an important natural resource issue today if not for the work of Kurt Cremer, who sadly passed away on 2nd June 2005 after a short illness.
