Assessing Fruit Tree Species Diversity in Home Garden Agro-Forestry and Their Role Supporting Local People’s Livelihoods in Burie District, Ethiopia

Clearing of natural ecosystems and land degradation due to unsustainable agricultural practices are becoming threats to the sustainability and productivity of agricultural systems in Burie town administrative, Amhara National Regional State, Ethiopia. The aim of this paper is therefore to assess the fruit tree species diversity in home garden agro-forestry and their role for supporting local people’s livelihoods in Burie town administration. Cultivated plants of 72 home gardens were surveyed and critical information were collected through questioner and focus group discussion from 12 households. Fruit tree species diversity (expressed in species richness and evenness) in home gardens in the study sites was determined using the Shannon-Weiner Index. The study basically considers the human consumption fruit trees species. A total of 18 fruit tree species represented by 9-genera and 7-families were recorded in home garden agro-forestry within the three wealth status (poor, medium, and rich) of the selected respondents commonly. From all wealth categories, the highest Shannon diversity index was recorded in rich and the lowest was in poor class category. Similarly, the highest species evenness was recorded in rich wealth category. However, there was no significant difference among rich and medium wealth categories for species richness. The study also revealed that age, land hold size, education status is the cause for species diversity in addition to the wealth status in the study area. Older respondents had significantly higher species richness and diversity than youngsters. It has been also found that almost all (100%) of the sampled households harvest and use at least four types of home garden products for various purposes. Lacks of management practices were the factors which puts the species diversity in question in the studyarea.
