Willow Warriors have five goals that help us prioritise our activities and these are included in our funding applications and are listed in no specific order:
• Controlling willows in areas of high conservation value. "Controlling" includes mapping and treating willows and monitoring for reinfestation. By "high conservation value" we not only refer to World Heritage Areas and National Parks, where gaining consent to treat the willows is easiest, but also private and public owned land that contains endangered species or habitats or unique surroundings.
• Controlling seeding willows because they can spread across catchments by wind blown seed re-infesting new areas which could have previously been mapped and treated. Whilst monitoring for re-infestation by fragile willows usually involves checking one or two hundred meters of river downstream of a fragile willow. Monitoring for re-infestation by seeding willows can involve distance of 50 kilometres or more in all directions or just the direction of the prevailing wind due the seed set months of October and November
• Controlling willows in areas to protect downstream or adjoining areas of high conservation value.
• Mapping willows by taxa along rivers in South East Australia to complete the taxa data being collected for the national willow mapping project. This will improve the community’s ability to prioritise willow control activities and upgrade the level of enforcement on the high risk taxa.
• Undertaking activities that allow volunteers to combine their enjoyment of adventure paddling and touring with conservation activities.
Willow Warriors have two projects that do not involve seeding willows. The first is the treatment of crack willows on the Goobarragandra River where they impact on the habitat of the Tumut Grevillea and the Booroolong Frog. The second is the treatment of crack willows on the Wingecarribee River where they impacted the unique rock canyon of Wallaby Rocks and also the Wollondilly River where they impact the Greater Blue Mountains World Heritage Area.
Apart from these our current projects involve mapping willows by taxa and where we have consent treating seeding willows as we go and making sure we cover National Park Estate where ever possible.
As we verify and update the willow mapping by taxa we will be able to amend the following regional prioritisation matrix and focus activities on controlling the high priority taxa in each region.
