Plant Species Diversity

1. Field Crop Diversity

Ethiopia is one of the major Vavilovian centers of origin/diversity for several domesticated crops and their wild and weedy relatives. It is an important primary and secondary gene pool for many field crop species that are useful sources of germplasm for economic traits in general and sources of genes resistance to diseases and pests in particular. Ethiopia is a primary gene center for field crops such as noug (Guizotia abyssinica), tef (Eragrostis tef) and the Ethiopian mustard (Brassica carinata). Besides, field crops such as barley, sorghum, durum wheat, finger millet, faba bean, linseed, sesame, safflower, chickpea, lentil, cowpea, fenugreek and grass pea have wide genetic diversity in Ethiopia… Read more

2. Forest plant diversity

The forest resources of the country were grouped in 5 categories, namely, natural closed forests, woodlands, bushlands, plantations and on-farm trees. The current area coverage of each category is not available. It was believed that about 35% of the landmass of Ethiopia was once covered with closed forests. The revised current estimate of the closed forest cover of Ethiopia was 3.5%. The total number of woody species of Ethiopia is estimated to be 1017, out of which 29 tree species, 93 shrub species and 2 liana species are endemic. These species are represented in 104 families and 387 genera. Recently, a new tree specieshas been identified in the Ethiopian Somalli Region and has been named as Acacia fumosa…Read more

3. Horticultural plant diversity

The major horticultural plant species grown in Ethiopia are categorized in five groups: root and tuber crops, fruits and nuts, stimulant and beverage species, herbs and spices and wild-edible species…Read more

4. Medicinal Plant Diversity

Eighty percent of the Ethiopian people depend on traditional medicine for their health care (Dawit and Ahadu, 1993), and more than 95% of traditional medicinal preparations in Ethiopia are made from plant origin (Dawit, 1986)…Read more

5. Pasture and forage plant diversity

There are diversified pasture and forage resources adapted to different ecosystems of the country. Studies show that 736 species of grasses, 358 species of legumes and 179 species of browse trees recorded so far in Ethiopia. Ethiopia is known to be a centre of origin and diversity to a number of herbaceous legumes species in the genera: Trifolium, Vigna, and Lablab, among others..Read more
