N2 - The distribution of floodwaters and their average recurrence interval (ART) on the lower Balonne flood plain in semiarid Queensland, Australia, was mapped using 13 Landsat thematic mapper (TM) images. The vigour of vegetation growth was also mapped from a normalized difference vegetation index (NDVI) transformed "reference image" showing average pixel value between images captured over a period of nearly 10 years. The area of each NDVI class in each ARI zone was calculated. The largest proportion of vigorous vegetation occurred where flood frequency was between 1.25 and 1.75 years. The smallest proportion of vigorous vegetation occurred where flood frequency was low. Vegetation with very low growth vigour was common only where flooding occurred more frequently than once per year. Possible explanations for this relationship include reduced plant vigour due to soil anoxia, the impact of disturbance frequency on plant productivity, and pixel mixing at the vegetation/water boundary
