Harvesting as an Alternative to Burning for Managing Spinifex Grasslands in Australia Table 1 Species contributing to a total cumulative contribution of 90% for each treatment are listed following SIMPER routine in Primer on floristic data collected in wet and dry season surveys in 2011. The species contributing to the highest abundance is ranked “1” followed by decreasing order. M = mature, R = resprouting, and S = seedling.
