Poplar damage assessment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Poplar damage assessments were conducted by observing all of the trees along particular planting rows (transects) and counting the number of trees with each damage type.

This datatable is part of the Poplar Biomass by Allometric Equations dataset. Poplars are grown as cellulose crop at the Main Cropping System Experiment. The first rotation was planted at a stocking density of 1 tree per 2 square meter. After the first harvest the trees were allowed to coppice. After the second harvest the trees were replanted. The third rotation was planted at 1 tree per 3.6 square meter. For the first two rotations the species planted was Populus nigra x P. deltoids hybrid for the third rotation it is Populus nigra x P. maximowiczii.
