Ethiopian Indigenous Trees (Amharic): Exploring the Diverse Flora of Ethiopia

List of Indigenous Trees in Ethiopia (Amharic)⁚ A Guide to Ethiopia's Flora

Ethiopia, with its diverse climatic and soil conditions, provides a favorable environment for the growth of native trees. Among the emblematic trees of this territory are Silky oak, Papaya, and Weeping fig. These trees hold great cultural and ecological significance in Ethiopia.

Ethiopias mountains are blanketed with shrubs such as pyracantha, jasmine, poinsettia and a variety of lavish evergreens. Common plants such as coriander, myrrh, cardamom, chat and caraway also populate Ethiopias diverse landscapes. Ethiopia boasts Africas only indigenous rose species...

Only some 8-10 decades ago, approximately 40 of Ethiopia was c o v e r e d b y f o r e s t s t h a t w e r e c o m p o s e d o f v a r i o u s i n d i g e n o u s t r e e species including podo, various acacia s, the African pencil cedar, wild olive, as well as many other tree sp ecies. But now the cover of real forest is less than 3, and a substantial proportion of this consists of trees of foreign origin, including the various Eucalyptus species. The importance of forests can hardly be overemphasized. The wood from the trees is used fo r fuel (either directly or after processing to charcoal), for the construction of houses, for furniture, as well as for other innumerable utilities. On top of this, many of the indigenous trees ha ve medicinal uses. But forests do not consist of trees only. They are homes for many other interdependent organisms, which cannot survive without the forests, and without which the forests cannot survive in the absence of significant human intervention. In a nat ural podo forest, for instance, animals like the Colobus mo nkey eat the fruits and process the seeds in such a way that they may germinate. Once the for est has been reduced to a few scattered trees, the animals are gone, and germination becomes more difficult or impossible. Hidden from our view, below th e ground in the forests, are other important organisms. Mycorrhizal fungi, specific for each t ree species, help the trees acquire the nutrients they need. When the last tree of a species is gone from an area, its fungus will soon disappear from the soil, and will not return by itself. Forests are important not only for the products that can be harvested from them and for the co mplex interactions they make with other organisms to build up and/or maintain the complex fabric o f biodiversity, but also for preventing erosion and for affecting the climate in a positive way. Moreover , deep roots of many tree species fetch nutrients from great depths, nutrients that can later be used by other members of the biosphere. Tr ees provide shade and variation to the landscape, and could assume econ omic importance also from the The value of trees was app reciated long ago and, as their number started to dwindle, farsig hted persons started afforestation programs. Not surprisingly, trees of foreign origin were chosen on grounds that they are easy to establ ish and are capable of growing fast. 6 Biology, uses and propagation techniques However, not all of them gave the an ticipated results. Already there are signs of tree die-backs, as well as o ccurrence of adverse effects on the natural ecosystem. Some of these problems are mentioned by the I n r et r os p ec t , w e m us t r e gr et that the indigenous trees were neglected --- to the point that the survival of some of them are now at stake and, as a consequence of the interdependence, the survival of those other organisms that have co-e volved with these natural forests. The main reason that indigenous trees were not used in the early afforestation projects is that their seeds do not germinate read ily, and that the seedlings are often not easy to establish. However, this is not always true since it is shown in this book that there are useful indigenous tree species whose seed lings can easily be raised from Ethiopia is one of the main cent ers of species diversity of the world. A large number of plant and animal species are dependent on the continued existence of indigenous forests. Although the main responsibility resides with the Ethi opian communities themselves, these indigenous forests constitute a h eritage of all humankind since we are all indigenous to planet earth. Fortunately the author of th is book, Dr. Leges se Negash, through a pioneering research conducted at the Addis Ababa University, has now solved some of the problems and worked out methods for the rapid propagation of some important indigenous trees, including Podocarpus falcatus (Thunb;) Mirb. To transmit this new knowledge to the wider communities is the responsibility of those concerne d with the rapi d disappearance of not only native trees and shrubs, but also water, soils and biodiversity. The completion of this b ook is an important part of this process, and it is my hope that it will reach a wide readership.
