Fagus orientalis tree's natural range extends from southeastern Bulgaria's Strandja mountain, through northwest Turkey, and east to the Caucasus Mountains in Georgia and Russia, to the Alborz Mountains in Iran. Its habitat is restricted to mountain forests, at of altitude. The Oriental beech has colonized even lower altitudes in the Strandja mountain of Bulgaria as low as above sea-level, due to the unique local micro-climate, where it forms typical "Fagus orientalis"−"Rhododendron ponticum" forests as well as with other evergreen shrubs.

Dioscorea sylvatica Dioscorea sylvatica Dioscorea sylvatica ("forest elephants foot") is a species of a twining tuberous vine that is native to Africa. It is common and widespread in forest and thicket, throughout the summer rainfall areas of East and Southern Africa. It produces a distinctively flattened caudex, often with lobes that spread out. The creeping shoots grow throughout most of the year, though each will periodically die back and be replaced from the central caudex root stock. In dryer conditions it can become deciduous. The green creeping foliage can reach 4 meters or more in height. It is an extremely widespread and
