Globally, Eucalyptus trees are widely used as industrial forestry plantations owing to their considerable biomass production potential and ability to serve as carbon dioxide sinks. However, their susceptibility to cold temperatures restricts the suitable areas for plantations. In Japan, the northern Kanto region, including Ibaraki Prefecture, which encompasses the University of Tsukuba campus, marks the northern boundary for Eucalyptus plantation-based cultivation. Nevertheless, the precise climatic conditions determining the feasibility of Eucalyptus tree plantations have yet to be fully explored.
