An Ethnobotanical Study of Wild Edible Plants in Tach Gayint District, South Gondar Zone, Amhara Region, Northwestern Ethiopia.

Abstract

The purpose of this study was to carry out an ethnobotanical and ethnopharmacological investigation on wild edible plants and their value to households in the Tach Gayint district of South Gondar Zone of northwestern Ethiopia. A total of 175 informants (56 women and 119 males) were interviewed for ethnobotanical data, and 25 of them were key informants. Data collection techniques included semistructured interviews, guided field walks, and focus group discussions. Quantitative analytical tools were employed for ethnobotanical methods including preference ranking and direct matrix ranking techniques to analyse the data. 36 species of wild edible plants have been identified in the study area. Of these plant species, shrubs account for 15 (42%), followed by herbs 13 (36%) and trees 8 (22%). Regarding the edible parts, fruits account for 19 (53%) followed by young shoots, leaves, and flowers, 4 (11%) for each. These plant species are eaten raw (86%) or cooked (14%) and most are collected by younger people for herding cattle. According to the preference ranking analysis, the fruit of Opuntia ficus-indica is the most preferred plant species because its sweet taste. Although Cordia africana, the most commonly used multipurpose wild edible plant species, is mostly exploited due to human activity, activities such as the production of charcoal, the gathering of firewood, the construction of homes, and the use of agricultural tools all played a significant role in the plant's eventual extinction. In the study area, agricultural expansion was the main cause of putting wild edible plants in danger. It is best to cultivate and manage edible plants in a backyard garden and to perform more research on popular edible plant species.
