\textbf{Abstract}
\begin{abstract}
\normalsize{
The Vietnamese government is currently carrying out a large scale "reforestation" programme (Five Million Hectare Reforestation Program). Smallholders plant a wide range of tree species where a large part of the planting taking place today in Viet Nam concentrates on fast growing trees, aimed at producing raw material for the pulp and paper industry or woodchips. Nearly eight million people living in or near forest lands spend much of their time for their livelihood security. Poverty is fundamentally a real problem in Viet Nam, with 90 percent of the poor living in rural areas and with incidence of poverty being much higher in rural areas than in urban ones. Poverty in Viet Nam will be mainly rural for the foreseeable future. For this reason, short"=to medium"=term poverty alleviation efforts will have to be heavily focused on forest. Forest resources have served and will serve the goal of poverty alleviation. In Phu Tho province, the most common fast growing exotic species planted are Eucalyptus urophylla and \textit{Acacia mangium}. The objective was to investigate growth potentials of Eucalyptus urophylla and \textit{Acacia mangium} in smallholder plantations for pulp and paper industry .Sample plots sizes of 75 to 315 m$^{2}$ were established in the study area. On the plot following variables have been observed: height (h), diameter (DBH at \mbox{1.3\,m}), spacing, elevation, slopes, aspect at the plot centre, and the accessibility and adjacent land uses. The values obtained are estimated for stand structure, stand density, volume and above ground biomass production .The results show that, the growth of Eucalyptus urophylla and \textit{Acacia mangium} are very good performance in the study area in Phu Tho province. The diameter and height growth in study area are high. The estimated total volume and above ground biomass are also well.
