List of references useful in southern and central Scandinavia

List of available Pinus references useful in Scandinavia

Baltic sea

• Swed022 ITRDB: swed022w.rwl Gotland 1128-1987, Schweingruber. A very useful reference. Unfortunately the youngest part, after about 1850 too narrow.

• SE005 (Gotland 1124-1987). Included in "Project EXTRATERRESTRIAL" [1] This collection seems to be based mainly on the same samples as Swed022, but measured independently and with other identities. A lot more samples from recent trees are included.

• Swed302 ITRDB: swed302.rwl info Nämdö in Stockholm archipelago 1583-1995, by Lars-Åke Larsson. A good reference with good correlations towards the Gotlandic references. Also single trees are often datable between Nämdö and Gotland.

• Swed313 ITRDB: swed313.rwl info Rälla Tall on the island of Öland, south east Sweden, 1858-2006 by Torbjörn Axelson. Good correlations towards Stockholm area, for instance Swed308 as well as to the quite nearby SE003.

South east Sweden, low elevations

• SE003 (Högelycke outside Nybro, south east Småland 1662-1998, Lunds Universitet. In "Project Extraterrestrial"[2]. Useful start for dating not too old samples from the region.

• Swed304 ITRDB: swed304.rwl info Sisshammar, Tyresta, Stockholm. 1661-1910, by Tomas Andreasson. Samples from an old farmstead.

• Swed308 ITRDB: swed308.rwl info Saltsjöbaden, east of Stockholm, by Lars-Åke Larsson AD 1733-2003. Also earlywood and latewood measurements are available.

• BratPISY BratPISY-rev. Mälardalen 1153-1904 "Washed version of the meancurve published by Alf Bråthen available here. Segments with low correlation values towards other, sometimes rather distant references like SE005 and SE007 removed, and an error in the oldest part is corrected.

• swed310 ITRDB: swed310.rwl info, Bettna Södermanland, (1661-1753), 1819-1997, (thin, only 0-7 stems), by Lars-Åke Larsson.

• Swed307 ITRDB: swed307.rwl info Lerbäck north of Askersund, 1778[1811]-2004, by T. Axelson. (The oldest part 1778-1811 consists only of 4 samples from the same tree, and is not representative).

Central Scandinavia (Southern Swedish highlands included)

• Swed309 ITRDB: swed309.rwl info, Aneby, Småland, (1744-)1784-2003, (1-)3-11 trees per year, by Lars-Åke Larsson and Per Zackrisson.

• 5church Chronology based on samples from five medieval wooden Churches in Småland and southern Östergötland AD 989-1344, by Lars Löfstrand publiched in the book: "Medeltida träkyrkor" ISBN 91-7192-544-9. Digital version

• Swed305 ITRDB: swed305.rwl info Björbo, Dalarna 1450-2002, Torbjörn Axelson.

• FlodaSn another referens from the same area as Swed305 by T. Axelson, AD 1405-2005. Probably a bit narrow because of too hard selection. The "thickness" of this collection is very varying. [3]

• GrangardePISY. Grangärde socken, South western Dalarna, 1366-2004, by T. Axelson. May be used alone or combined with other references. [4]

• SE007 Master chronology for Dalarna, 931-1888). Publiched by Lund University in the Project Extraterrestrial[5]. Very useful and surely "thick", except for the part before about 1040 wich seems to be based on very few samples only.

• Prostparken, Svärdsjö, Dalarna A sandy ridge, 1664-2005, by Bertil Israels. [6]

• Bingsjö-PISY, Northeastern Dalarna (relatively high elevations], 1400-1859, by B. Israels. [7]

• Swed023 ITRDB: swed023w.rwl Jämtland, Schweingruber, 1107-1291, 1316-1827. Note! This collection also contains some PCAB samples. The same material is available also though WSL Dendro Database, Switzerland. http://www.wsl.ch/dendro as JAEMTUA_190_PISY_R.tuc with the PISY samples only.

This article or section needs translation

• 2008 har H. Linderholm på ITRDB publicerat ett större antal tallkurvor för Sverige, en del av dem från tallar som vuxit på myrar. Dessa kan antas avvika mer eller mindre kraftigt från tallar på fast mark, och kan vara av intresse för att datera prov från träd som vuxit på liknande mark, och som ofta kan vara svåra att datera mot standardkurvorna. I listan anges tidsintervallet och intervallet med minst 4 provers djup. Se Swed314-328.
