“…C. abyssinica, C. africana, C. alliodora are species that have wood utilized in production of high-quality furniture and other objects and domestic utensils. It is highly valued commercially in Ethiopia, and it is also a native species of Saudi Arabia and tropical Africa (Derero et al, 2011).…”

Juniperus procera is economically highly important but threatened tree species. It is the only species among 67 taxa in the genus Juniperus that naturally grows in Africa and south of the equator extending up to 18°S in Zimbabwe. Ethiopia is assumed to host the largest J. procera populations, which are also believed to have high genetic variation owing to their wide ecological amplitude. This study assessed genetic variation at AFLPs of J. procera populations in the Ethiopian highlands. In the study six populations, namely Chilimo, Goba, MenageshaSuba, Wef-Washa, Yabelo and Ziquala were included. A total of 20-24 trees from each population were investigated based on 128 AFLP band positions. AMOVA revealed that most of the variation (94%) resided within populations of J. procera suggesting extensive gene flow among populations which is attributable to the outcrossing mating system and effective gene transport mechanisms of the species. However, genetic differentiation among populations was still significant (P \ 0.05), and the differentiation was significantly (P \ 0.05) correlated with geographic distance. All population pairs were significantly (P \ 0.05) differentiated except for Menagesha-Suba and Wef-Washa. These two populations also showed the highest gene diversity (H j = 0.301 and H j = 0.297, respectively). These results are in accordance with historical records that claim the establishment of the Menagesha-Suba juniper population as plantation of seedlings from Wef-Washa back in fifteenth century.

“…The other negligible challenges of seedlings plantation in this work was those seedlings that died or at risk while transportation for plantation. The aforementioned constraints are similar to those facing the forest development in Ethiopia as noted by Derero et al (2011) which include: transportation of seedlings, poor seedling quality and inappropriate silviculture, poor research extension linkage and poor coordination in the sector.…”

The study was conducted to explore the growth and survival rate of the native tree species of Ethiopia, Olea africana and Hagenia abysinicca in Lake Haramaya Watershed, Eastern Ethiopia. Three sub watersheds of Lake Haramaya Watershed, namely, Bachake, Damota, and Tinike were selected purposefully on the basis of their extreme degradation and nearby vanished Lake Haramaya. In each sub watersheds, a total of about 12 main standard quadrats have been applied and the required data has been recorded. The result of the study indicated that O. africana performs well at Damota sub watershed, accounting 38% of survival rate followed by Tinike sub watershed having a survival rate of 37%. Only 29% of the total planted O. africana were survived at Bachake sub watershed. Furthermore, it has been revealed via this study that about 55.6% of H. abysinicca survived at Damota sub watershed. Comparing the survival rate of the two species, H. abysinicca better withstand and grow under an extreme pressure of local peoples intervention at all sub watersheds. Therefore, the study shows that growing and maintaining of these two endemic trees in all sub watersheds were difficult task unless much awareness will be made. Lastly, the study encourages mega projects on growth and survival rate of other native trees species and explores the challenges associated with growing these trees in the study area in specific and in Ethiopia in general.
