GrangardePISY

GrangardePISY, a collection of Pinus sylvestris samples from Grangärde parish is southern Dalarna 60°15′N 14°58′E AD 1366-2006 (samples from at least 4 trees: 1412-2006), by Torbjörn Axelson. The altitudes are from 150 m (Lake Väsman) and mainly about 200 m, but some smaller areas are also above 300 m and even a few around 400 m. The samples are from various sites, both from living trees and several buildings in the area. Some of the living trees have had their roots in contact with lakes (Samples with identities starting with Mal... are from around lake Malingarna and those with Korss... from around the lake Björken). The chronology is still weak for the period 1766-1802 (samples from only 6-9 trees) and before 1504 (samples from 1-9 trees.

This chronology (version from 2006) has also been used in combinations with other chronologies: BjörboGr (swed305+GrangardePISY) and SödraDal (consisting of most available samples from southern Dalarna).
