Abstract

Sustainable management of economically and ecologically important tree species such as Faurea rochetiana merely depend on acquiring reliable information on growth dynamics and structure in response to the changing climate. Formation of the growth ring boundaries is pre-requisite for conducting several denroclimatology studies. Hence, the objective was to verify the formation of growth ring boundaries of F. rochetiana. Fifteen sample discs were examined for macroscopic and microscopic wood anatomy features and compared with IAWA list of microscopic features of hardwood identification for wood anatomy characterization. The result revealed that the studied tree had indistinct growth ring boundaries. Consequently, the studied tree is not a potential candidate for further denderoclimate studies.   Key words: Wood anatomy, growth ring, South Omo, Faurea rochetiana.

Highlights

Ethiopian dry forests are habitats for many endemic plants and animal species which has a varied ecological, social and economic importance (Lemenih and Bongers, 2011, Worku et al, 2011)
For instance climate change has a considerable effects on includes growth rates and dynamics of many plant community, composition, and distribution of plant populations (Siyum, 2020)
The objective of this study is to characterize the macroscopic and microscopic wood anatomic features of F. rochetiana, so that it is potential for further dendroclimate studies can be checked out?

Summary

Introduction

Ethiopian dry forests are habitats for many endemic plants and animal species which has a varied ecological, social and economic importance (Lemenih and Bongers, 2011, Worku et al, 2011). Despite, these forest resources are being highly destroyed due to agricultural expansion, human-made fire and illegal harvest of woods, over grazing and climate change related threats (Atmadja et al, 2019, Lemenih and Kassa, 2011). For devising successful strategies for these forest resources, acquiring reliable data on for instance growth rates, population structure and, the climate-growth relationship is important (Rozendaal and Zuidema, 2011; Worbes et al, 2003)
