Outline of Final Research Achievements

The objective of this study is to clarify the water use strategies of trees in arid environments using soil/stem water monitoring and stable isotope ratio analysis of water. The plants used for data collection were Prosopis juliflora (mesquite: invasive) in Sudan and Tamarix ramosissima (tamarisk: invasive) and Prosopis pubescens (screwbean mesquite: native) in the United States. The results from America, Sudan and Japan clarified the various unique water use characteristics of each species.
