Abstract

The BOReal Ecosystem-Atmosphere Study (BOREAS) is a large multinational study of boreal forest interactions with the atmosphere. Carried out mainly in two study areas in Saskatchewan and Manitoba, BOREAS included a significant biometry component. This report, the first of two Canadian Forest Service reports on the dendrochronology of BOREAS samples, describes the tree allometry sampling program, and it presents the results of X-ray densitometry analyses of tree allometry samples collected in the BOREAS program. These samples are mainly cross-sectional slices of trees collected at regular intervals from the base to the top of the crown. The sampled trees come from six of the tower sites and two auxiliary sites. In all, 938 samples from 75 trees are reported on here.
