Abstract
Botanical gardens are playing a great role in our planet to protect and conserve the biodiversity of the world. Especially it protects plants and animals those exposed to be extinct. Botanical gardens also help to balance the ecosystem of the world. Gullele botanical garden is a newly established botanical garden in Ethiopia that is located at the North Western part of Addis Ababa. As other botanical gardens, the Gullele botanical garden is used to grow and display plants primarily for scientific and educational purpose. It also includes herbarium, lecture rooms, laboratories, libraries, museum and experimental plant research rooms. The comparative studies of the survival pattern of the planted tree species in Gullele Botanical Garden (GBG) on Hamle 22/ 2011 E.C. ( July29/2019 G.C.), to identify the survived and not survived planted tree species in the botanical garden. During planting trees there were sixteen different types of tree seedlings with 4627 in total population. The thesis was identifying the total number of tree species by their scientific & local name and registered the survived planted tree species in the study period (October—April 2011E.C.). The paper also contains the survival percentage of each tree species and the growth rate of eight tree species in the study period of time. Overall survival percentage of each planted tree species and relative growth rate in height of eight indigenous tree species measured in the study periods. The aims of the botanical garden were replacing the eucalyptus trees by the indigenous plant species such as Acacia abyssinica (Bazragirar),Podocarpus falcanus (Zigba), Millettia ferrgunia (Birbira), etc.. The thesis paper contains five chapters, the introduction, review literature, methodology, results, discussion, conclusion and recommendations. The introduction part contains, the definition of botanical garden, the role or benefits of plants, the problem of destructing plant species, measures taking to protect plants, the significance of the problem and the objectives of the study.
