Annex 2. Table of Trees, Shrubs, Flowers and Herbs to Introduce in the Entoto Natural Park. Description of Characters of Seedlings to be Planted in the Park Area Table 1 is based on a meeting at the National Herbarium with Sue Edwards, editor of the Flora "Some Wild Flowering Plants of Ethiopia" (Edwards 1976). Some of the plants in the table are already present in the Entoto area but in various quantities. Some species belong to open areas, and some are forest plants. (A detailed inventory of the vegetation of Entoto started in October 1994.) To get an idea of what can be grown in the Entoto Natural Park, table 2 shows the composition of different vegetation stratas in the Menagesha State Forest, set together by Dr. Sebsebe Demissew at National Herbarium (published in Mountain Research and Development Studies Vol. 8, number 2, May 1988). The indigenous  Podocarpus falcatus (P. gracilior)   tree is scarce on Entoto; it seems that it can no longer give surviving progeny in t...

Biodiversity In biodiversity, the most common and straightforward misinterpretation is that it refers to a range of ecological benefits derived from a variety of lifeforms within a natural type. However, despite its simplicity, this interpretation can be downright misleading and even seriously incorrect. The reasons for the incorrect understanding of diversity in biodiversity are varied and often complicated. Still, the main one is that each habitat has its own limitations and advantages, which are definitely not suitable for interpreting as a host for foreign biodiversity. In reality, each unique habitat is often susceptible to the endemic species of its own prehistoric past, where the original Nature instead risk enduring biodiversity sensitivities, with direct limitations and vu...
