This study was designed to investigate the diversity, conservation and regeneration of edible wild-food plants in Wisin Woodland Forest of Bullen Rural District, Western Ethiopia. A straight line method and a cross-sectional research designwas used to achieve a systematic distribution of sample plots. Moreover, some other datas were collected through semistructured interview and focus group discussions. All the variables were tested across the forest utilization zones (mountain forest and lowland reserved forest and unreserved) using one-way Analysis of Variance (ANOVA) and Multivariate analysis by using SPSS software. A total of 64 species of plants representing 21 families were identified the studied species were from the family Fabaceae (45.3%). Among the studied plant species, 31 were wild food plants. Among the studied wild food plants, the most commonly preferred species were Vitex doniana and Tamarandus indica , while Dalbelgia nitidula was the last among the first 10 tree species. The results indicated that there was a significant difference (p<0.05) in the growth forms of wild food plants among the sits. In all the sits studied, the tree species of low diameter classes were more than fourfold, compared with other classes. There was significant difference (One-way ANOVA, p<0.05) in the tree sits and this shows declining trend from the lowland forest reserve, to the mountain forest reserve and unreserved forest. The results on species diversity showed a significant difference (One-way ANOVA, p<0.05) among the three sits. The local communities surrounding the WWF are highly dependent on the wild food plants during food scarcity. The results indicated that due to the high dependency of these wild food plants, there is decreasing trend of plant resource and this has been reported by 94.4% (n=85) of the respondents.

O ipê-amarelo (Tabebuia serratifolia) é uma espécie florestal com potencial madeireiro, porém,
pouco utilizada em plantios florestais, devido à escassez de informações sobre sua produção tanto
em viveiro quanto no campo. Diante disso, realizou-se experimento com o objetivo de verificar
os efeitos da calagem no crescimento e na nutrição de mudas de T. serratifolia. O calcário foi
misturado ao solo Latossolo Vermelho distrófico de textura franco-arenosa, em sacolas plásticas
com capacidade para 2,5 kg. Os tratamentos foram dispostos em delineamento inteiramente
casualizado, com cinco repetições: testemunha (26,5%); 60%; 70%; 80% e 100% de saturação por
bases. Após 120 dias, avaliaram-se: altura, diâmetro de colo, relação altura e diâmetro, biomassa
seca e índice de Dickson. As plantas secas foram submetidas às determinações dos teores de
macronutrientes. Os melhores resultados para crescimento da T. serratifolia foram verificados
no nível de 70%, principalmente porque N, K, Ca e Mg foram disponibilizados em concentrações
adequadas, possibilitando o incremento.
