The following images show the overall health of the Robinson River. Each side of the river was analyzed independently by assessing seven different variables according to a set protocol. Sweepers analyzed canopy, buffer, bank erosion, river bed, bank cover, and bank geometry. Each variable was assigned a numerical value based on its quality, and every time there was a change in one of the variables along the river, all seven variables were reassessed and recorded. After Sweepers finished the assessment, the total numerical value of the variables was added together for each position, and using graphical analysis the points were grouped into areas of good health (green) fair health (yellow) and poor health (red).
Note: Arrow indicates direction of river flow.
