This study assesses the effectiveness of three combined techniques (subsoiling, seeding, and mulching) for the restoration of degraded tiger bush in western Niger, a region particularly vulnerable to land degradation. Four 150 m² plots were established: subsoiling alone (SL), mulching alone, a combination of subsoiling + seeding + mulching (SL+E+B), and an untreated control plot. Subsoiling was repeated over three years (2016–2018), while mulching and seeding were applied at the beginning of the experiment. Vegetation was monitored over five years using floristic surveys and dendrometric measurements. The main results indicate a significantly higher plant density, increasing from less than 1 plant/m² to nearly 6 plants/m² in the SL+E+B plot; a notable improvement in floristic diversity, with higher Shannon and Simpson indices, indicating better species distribution; and increased sustainability of restoration effects in the SL+E+B plot, where vegetation persisted and diversified over the monitoring period. These findings suggest that combining multiple land management techniques is essential for the durable and optimal restoration of degraded ecosystems in the Sahelian context.
