Dereje is a botanist working on plant biodiversity in different ecological systems (including sacred sites). Currently, he is studying towards a PhD, quantifying the impacts of climate and land cover / land use change on forest biodiversity and carbon storage in the Jimma Highlands of Ethiopia.
Dereje has many years of teaching experience, and has worked as Research and Project Assistant for the Biocultural Diversity Project (Ethiopian Wildlife and Natural History Society). His Masters research was on the Floristic Composition and Ecology of Bibita Forest in Southwest Ethiopia, in which 196 species of plants were identified, of which two species were new records (Ipomoea involucrata and Harungana madagascariensis) for Ethiopia.

PhD title: Impact of Climate and Land Cover Change on Forest Biodiversity and Carbon Storage in Jimma Highlands, Ethiopia
Supervisors: Prof. Ensermu Kelbessa, Dr. Robert Marchant, Dr. Tadesse Woldemariam
Funding: Ministry for Foreign Affairs of Finland (CHIESA Project)
The purpose of this study is to determine the impact of climate and land cover change on forest biodiversity and develop regional species distribution model. It is also to estimate the carbon storage of different land use types in Jimma transect based on the above ground live biomass and upscale it to the landscape level.
The specific objectives of this study include:
Transects will be established and botanical assessments conducted. Additional occurrence data of the species that occur in the study transects will be collated from herbarium specimens, in order to constrain the climatic niche of the species. Maxent and Garp tools will be used for modelling the species distribution. Data for the determination of carbon storage in different land use types will be collected from 1 ha plots, stratefied by biome type. R-Statistical software will be used for the analysis of carbon storage under different land uses. Canopy structure and leaf area index (LAI) will be also determined, using a hemispherical camera system and Sunscan delta-T device.
