Abstract
Bullen district is noted for its rich diversity of plant species apart from wetlands to flood plains serving the habitat requirement of several inhabitant communities and is unique in its nature by having rich diversity of wild edible plants A number of cultivated tuber food plants such as Qocho Dioscorea cayenensis Anchote Coccinia abyssinica Sekuar Dinich Ipomoea batatas Dinich Plectranthus edulis Zingibil Zingiberof ficiaale and Godere Colocasia esculanta etc having their wild relatives such as Colocasia esculenta Curcuma bulbifera Dioscorea prehensilis Dioscorea hispida and Dioscorea oppositifolia etc are present in the district The present survey encompasses documentation previous of wild tuberous plant species belonging to family and genera tabulated with botanical name local name and family habit and habitat mode of consumption and medicinal uses
Highlights
Plants provide food and medicine besides protecting the environment and are very important for survival of peoples
Western region of Ethiopia is rich in the floral diversity of roots and tubers
The hotspot contains a large number of wild relatives of cultivated tuber crops as well as many under- exploited tuber crops known to tribals
Summary
Plants provide food and medicine besides protecting the environment and are very important for survival of peoples. The Ethiopian flora has approximately 6000 species of higher plants of which about 10% are endemic.[9,10] The country is known as the biodiversity hotspot and center of origin and diversification for a significant number of food plants and their wild relatives.[11] The wide range of climatic and edaphic conditions permitted the growing of a variety of wild food plants.[12] Some studies in Ethiopia indicated that many rural people are endowed with deep knowledge on how to use plant resources This is true with regard to the use of medicinal plants[13] and wild edible plants that are consumed at times of famine and other hardships.[7] In this regard, the elder community members are mostly the key sources of knowledge about plants.[7]. This study was designed to identify and document wild edible tuber plant species,[8] identify and record the parts and mode of consumption of wild edible tuber plants,[7] evaluate the exploitation and conservation status of the species, and[15] assess threats on the wild edible tuber plant species and recommend the possible management scenarios for their conservation
