Looking after Tasmania's Environment since 1968
Strategic Planning for Willow Management in Tasmania
Contents
Acknowledgments
Introduction Why Have This Framework? Background Tasmanian Weed Management Act 1999 Purpose of the framework
Applying the Framework Framework Explained Step 1: protecting high conservation values Step 2: identifying regional priorities -The scale of the infestation -Position in catchment Step 3: identifying catchment priorities -Relative position along the river -Capacity of the system to recover" -Proximity to native vegetation Assessment procedure
Decision Making Process for Setting Priorities
Appendix I Applying the Prioritisation Process Explanation of biophysical characteristics Position in sub-catchment Position within river Recoverability of system Geomorphic condition Proximity to native vegetation - Land management impacts - Habitat connectivity Potential for works to cause environmental damage
Site Assessment Sheet Part 1. Does the infestation address a 'priority 1’ issue? Part 2. Level of infestation in association with conservation values Part 3. Biophysical context of the willow infestation
Appendix II Mapping the Extent and Distribution of Willow Taxa in Tasmania Objective Methods -General -Data collection Results Data limitations
Appendix III Willows - Weeds of National Significance Salicacaeae Reproduction Distribution Priority willow taxa Seeding willows - Salix cinerea Environmental impacts -Impacts on river geomorphology -Impacts on stream ecology -Impacts on riparian ecology Willow control
Appendix IV Willow Species Found in Tasmania Tree willows (Salix) Shrub willows (Vertix)
Appendix V Best Practice Willow Management Assessing the problems A change in approach -Post-removal management -Revegetation Areas of high conservation significance -Threatened species Local impacts on threatened species -Priority vegetation communities. -Geo-conservation sites Areas of light willow infestation
Appendix VI Future Focus Future research needs and knowledge gaps Monitoring and evaluation
Appendix VII Further Information Publications References List of contributors who provided information for the mapping process
