Reporting non-native invasive species (NNIS) is a powerful tool for identifying potential problems and seeking action as soon as possible. It is therefore important to follow a few simple guidelines when reporting incidents.

  1. Report the NNIS location as soon as possible with a brief but accurate description (no more than 1000 characters).
  2. Do not make any derogatory comments or use inappropriate language (see the Disclaimer at the bottom of this page).
  3. Before you report a new NNIS, be sure to check it has not been reported already. If it has, you can update the existing report.

All NNIS locations are shown as coloured icon markers on a map where the colour plus 2 or 3 text characters indicates the species. A NNIS report may consist of more than one report and can be updated at any time. For example, a photograph may be added after the main report has be submitted, or additional reports added at a later date when necassary.

Existing NNIS reports can be viewed by clicking/touching the appropriate marker (or selecting from the drop-down list) to display the report page. From this page, the Update menu displays a form to create an additional report.

New NNIS reports can be created by selecting the New Report on the menu. Clicking or touching the map displays an arrow marker on the NNIS location. If required, the map's Zoom options (+ and - buttons at the bottom right of the map) can be used to increase or decrease the zoom level for higher accuracy.

The report form contains six fields to select/complete:

  1. Invasive Species Type: (defaults to Asian Hornet).
  2. Catchment: If appropriate select the catchment area.
  3. Water Types: If appropriate select the water type.
  4. Severity: Select one of five categories.
  5. Set Marker: marker points left or right.
  6. Description: e.g. extent, problems caused or action taken etc.

If one or more photographs are to be included, these should be uploaded before the report is submitted. Photographs can be added by selecting the Add Image menu. Ideally, photographs should be taken in Landscape mode.
