Preliminary results of comparing biologically rehabilitated areas, where three different methods were applied at the same time, to background control showed that sapling planted area greatest similarity (75%) and no difference in vegetation cover biomass (t = -0.88, p 0.40; t -0.22, 0.83) with control. In contrast, hydroseeded was 45.5%, while drill seeded least similar (0%). This suggests plan...
