Abstract
BackgroundWild edible plants (WEPs) have an important role for rural communities in safeguarding food security, nutritive variation and continued earnings. Their significance, management and utilization are not fully documented. Objectives are to identify and document wild and semi-wild edible plants (WSWEPs) and their conservation status in Berek natural forest, Oromia special zone.MethodsVarious data collection tools were employed to gather data on WSWEPs. Ethnobotanical data were collected from 142 household representatives (77 men and 65 women) being at least 14 years old. Most of them (73.9%) had not received formal education. Data were analyzed using descriptive and inferential statistics, preference ranking, paired comparison, direct matrix ranking and informant consensus factor.ResultsA total of 34 useful WSWEP species belonging to 32 genera and 24 families were collected and identified. The family Rosaceae had the highest number of species (five species, 14.7%), followed by Anacardiaceae and Solanaceae with three species (8.8%) each. Growth form analysis showed that the majority of the species were trees (14 species; 41.2%), followed by herbs and shrubs (10 species each, 29.4%. These edible plants were available in different seasons; 15 (44%) of the plant species reached maturity in spring season while seven species (20.6%) were found in all seasons and eight (23.6%) species were able to reach maturity in autumn and winter. Although most of the local communities have an intimate relationship with their natural environment, there are common threats to WSWEPs and their habitat, particularly through overgrazing, fragmentation of the vegetation for agricultural expansion, introduction of exotic species, selective logging for construction purpose and charcoal making.ConclusionWSWEPs are valuable resources for improving the environment, food and nutritional security and income of households in rural areas. Moreover, to sustainably use edible plant species of the study area local communities and the Forest Administration should collaborate in managing these resources before becoming critically endangered.

Wild edible plants (WEPs) have an important role for rural communities in safeguarding food security, nutritive variation and continued earnings
Most edible plants are documented elsewhere in Ethiopia: 16 species of wild and semi-wild edible plants (WSWEPs) were recorded in Berehet District, North Shewa Zone of Amhara Region with emphasis on WEPs [57]. 10 potential but underutilized fruit trees and vegetables were found in Tigray, northern
The study area is rich in WSWEPs, with high diversity and with associated indigenous information
Summary
Wild edible plants (WEPs) have an important role for rural communities in safeguarding food security, nutritive variation and continued earnings. Their significance, management and utilization are not fully documented. Ethnobotany in broad terms is the study of direct interrelations between humans and plants [1, 2]. This includes plants used as food, medicine and building material and for any other economic application. WEPs are gathered for food, nutrition and livelihoods by different peoples around the world These plants are gathered from varied habitats like natural forests, agricultural fields, as well as disturbed areas such as roadsides and waste lands. Various studies have found WEPs a potential source of nutrition as they are in many cases more nutritious than conventionally eaten crops [6, 7]
