| Abstract | Like other dendrochronological networks in the world, the ARCHIVES group has established a collection of sites based on a stratified sampling plan taking into account average hydric conditions (mesic
environments), in terms of exposure, and seeking to represent the major regional types of forest formations (spruce-lichen and spruce-moss forests). The distribution of sites also took into account the altitude, continentality and latitude to achieve
at best the geographic coverage over the area stretching from James Bay to Labrador and between the 53rd and 56th parallels. The homogeneity and density of the stands, the age of the trees and their physiognomy were selection criteria used to
eliminate certain possible effects such as competition during plant succession and other factors related to the heterogeneity of the sites or of the life history of trees. The area covered by the ARCHIVES network is 360,000 km2, a territory large
enough to allow the combined analysis of climate and hydrological model data and dendrochonological data. For the millennial series, subfossil trees were sampled in a set of lakes selected on the basis of catchment physiography, spatial distribution
over the vast designated area and fire history. The laminated sedimentary series of a few lakes were also used to complete the multi-proxy approach put forward in the ARCHIVES project. Finally, ARCHIVES used a complex assemblage of grid data obtained
by kriging of instrumental registers, reanalyses and modeled series. |
