Résumé

The relationships between site quality indices (SQI) (estimated height at age 50) of black spruce and Jack pine and site characteristics were investigated over a large territory in the boreal forest of Quebec. The relationships with degree-days (DD) and parent material, which are considered as permanent site factors, were significant for both species. Linear regressions with these two parameters as independent variables explained about 40% of the variability in site quality indices for black spruce and Jack pine. The addition of soil chemistry and biological data to this model indicated a significant contribution of exchangeable Mg concentrations or Al:CEC molar ratios in the forest floor and lichen cover to the prediction of site quality indices. Inclusion of these variables increased the model R<sup>2</sup> up to 60% for both species. Whether these variables reflect permanent site conditions or conditions related to the history of the sites is unknown. © 2004 Elsevier B.V. All rights reserved.
