In contrast, the similarity of the hydroseeded area was 45.5%, while the drill seeded area was the least similar to the control area (0%). This suggests that the sapling planting method was the most successful rehabilitation method. However, the study will be continued to include more rehabilitated areas and allow more time for vegetation recovery in rehabilitated areas
