Abstract:
Die Tabelle enthält den monatlicher Umfangszuwachs (Mittelwerte für die Arten) von etwa 260 Bäumen 12 häufiger Arten im ECSF-Gebiet. <br/>
Pro Art wurden zwischen März und Juni 1999 17-30 Stämme mit Dendrometerzuwachsbändern ausgestattet. <br/>
Diese werde seitdem im monatlichen Rhythmus abgelesen. <br/>
Angegeben sind für jede Baumart jeweils der Mittelwert für jeden Untersuchungsmonat für den Zeitraum Juli 1999 bis Januar 2003. <br/>
Die mechanischen Dendrometerbänder sind aus Aluminiumblech und wurden im Eigenbau hergestellt. Die monatlichen Messungen erfolgen auf 0,5mm genau. Soweit die Dendrometer noch funktionsfähig sind laufen sie noch (Stand September 2004), werden allerdings seit Mitte 2003 nur noch vierteljährlich abgelesen
Additional Infos:
This dataset has been migrated from the previous FOR402 Database to the FOR816 Database.<br/>
This has been done by the Central Datamanagement Z1/FOR816.<br/>
Please keep in mind that the migration included all avilable metainfomation which were accessible from the FOR402 Database but it can't be guaranteed that thematic missinterpretation occure in the data/attribute description.<br/>
There has been no further disciplin specfic control. In any case of ambiguity contact the dataset creator.
