This study was undertaken in Duguna-FangoWoreda of Wolayta Zone, in Southern Nations, Nationalities and Peoples Region to assess role of land restoration practices, to the regeneration of native woody flora in the Woreda. Both primary and secondary data were collected and purposive sampling technique was employed to select sample kebeles from 26 total kebeles of the Woreda. For regeneration status assessment, a total of 32 20m × 20m sample plots; 16 plots in the area exclosures and 16 plots on the adjacent abandoned land were taken, from which seedlings and saplings of native tree/shrub species were counted and recorded on the data collection sheet. Qualitative data of household survey was analyzed by interpretation and narration while quantitative data was analyzed by using descriptive statistics. The findings of the study indicated that Area enclosure, soil and water conservation and agroforestry practices were the major restorative practices undertaken in response to the land degradation. The total area of land held for restoration in the study kebeles comprised 1250 ha. From this almost 70% of the land area was rehabilitated through SWC activities and tree plantation with the seedling survival rate of 86%. A total of 340 individuals of different naturally regenerated woody plant species were recorded and whose density was 28.3 and 13.7 per ha of seedlings and saplings in area closures respectively. Similarly, 12 and 8.6 per ha of seedlings and saplings were recorded on adjacent abandoned lands in four study kebeles respectively. The difference in species density, diversity, richness and similarity in terms of seedlings was highly significant (t=3.89, df=3, p=0.03) and saplings (t=6.71, df=3, p=0.007). The forest cover of the study kebeles which was 623 ha in 1986 increased to 1148.05 ha in 2018 due to the implementation of restorative practices.
