During the period 2003-2020 I have don quite a lot dendrochronology in Grangärde and Säfsnäs, Ludvika Municipality, Dalarna. Historical timbers from meny buildings as well as from some living trees have been sampled, in most cases with Haglof increment borers 5.15 mm, usually scanned in 2400 dpi, and than processed with CooRecoorder and CDendro from www.cybis.se. The two locations are less than 40 km apart, but differs in altitude about 200 m in average, and the practical work has shown that two separate reference chronologies often are useful at least for difficult samples. Therefore I now have assambled two new pine (Pinus sylvestris) reference collections out of this material, one representing the lower area around Grangärde and the lakes Väsman and Bysjön (155 m.a.s.l) (60.24, 14.97), from living trees or logs from buildings, which I expect being cut in the near surroundings, and therefore rarely from altitudes above 250 m.a.s.l. The other collections is from living trees and logs in buildings from at least 300 m.a.s.l and up to 470 m.a.s.l. within or near the border of Säfsnäs parish (60.14, 14.48). The correlations pattern maps below visualize how the Säfsnäs collection generally gives lower corr values towards south east Sweden and slightly better towards central (and northern) Scandinavia, while Grangärde has the opposite tendency. My suggestion is that what is seen is that Säfsnäs collection has a stronger temperature signal (T) and a weaker precipitation signal (P) while Grangärde has a weaker T and a stronger P. The Björbo collection (ITRDB:swed305) (~30 km north has a mean altitude in between) gives a more balanced picture (not shown).
