MAPPING OF HIGH PRIORITY WEEDS

The Sydney Metropolitan CMA, together with the Sydney Weeds Committees, is currently coordinating a project to map the distribution and density of selected high priority weeds in the region.

Click on the links below to see the latest maps showing the locations of high priority aquatic weeds in the Sydney region. They have been compiled from existing maps and information collected over the last 5 years by councils and state agencies, and are being used to guide the project's more detailed mapping.

The project involves surveying and mapping, in cooperation with land management agencies, to produce up to date SMCMA-wide digital information of the distribution and density of five priority weeds: Ludwigia peruviana, Ludwigia longifolia, Salvinia, Senegal Tea Plant and Water Hyacinth. Alligator Weed is also being mapped throughout the Sydney and Hunter regions under a separate DPI project.

Mapping is being carried out in accordance with the recently developed Regional Weed Mapping Guidelines, and because these guidelines have been based on the National Weed Mapping Standards, all mapping works will be able to be shared at a State and National Level.

A contractor has been engaged to carry out the project and will be liaising closely with all relevant land management agencies in the Sydney Metropolitan region – including local councils, and state and federal government agencies.

Land managers will also be encouraged to participate in FREE GIS Weed density mapping training. It is hoped that through the combination of training and participation in the project, land managers in the region will have the capacity to carry out similar mapping independently in the future.
