Permanent and temporary plots in unthinned Pine stands
Description
Appendix 3. List of materials for chapter 3 of dissertation.
Appendix 3 has been scanned to PDF from physical copy, encoded run adobe character recognition and corrected by visual inspection.
Later copied and pasted to Excel, where it was sorted into spreadsheet columns and rows by Carl Vigren.
Geographical region south: counties A - U.
Geographical region north: counties W- BD.
Excerpts from the English summary:
"In chapter 3 a material is analysed, which consists of 680 revisions of both permanent and temporary plots.
The only uniform information given about the establishment of the stands in this material is whether the stands
are planted or not. Stand age varies in the material between 12 and 260 years, top height between 2.5 and 27.9 meters
and stem number per hectare between 173 and 34'917. The material is given in table 3.1. Some important stand variables from each plot and revision are listed in appendix 3.
Permanent and temporary plots differ systematically, especially in higher stands.
