This database contains the data deriving from a continous inventory in a ten year span in permanent sample plot of poplar stands in northern Italy.

It contains dendrometric information such as tree diameter at breast height and at 5 metres above ground, total height and total volume as well as the volume at 5 metres above ground.

It contains the planting year and the measuring year for each individual and for each permanent sample plot are shown the UTM coordinates in the ED50 reference system.

数据集涵盖测树学相关参数，具体包括树木胸径、离地5米处直径、总树高、总材积以及离地5米处材积。
每株林木的定植年份与调查年份均有记录，各永久样地的通用横轴墨卡托（UTM）坐标采用1950年欧洲大地基准面（ED50）参考坐标系，相关数据亦同步收录。
