| PostTreat_1969.csv |
\Data |
Comma-delimited ASCII text (CSV) file containing data collected after the stand was treated, but before detailed measurements began. It has a row for each plot followed by a count of trees on each plot in each height class. The height classes missing the decimal point since that does not work well in variable naming. Thus ht_05 is a count of trees in the 0.5-foot height class and ht_135 is the count of trees in the 13.5-foot height class. |
| PreTreat_1968.csv |
\Data |
CSV file containing data collected before the study treatments were applied. There is one row for each plot with columns for each of the 25 milacre plots which were used to sample the stand. Each milacre has a count of all trees found (all_?) and a count of trees found that had started height growth (htgro_?). |
| study320.csv |
\Data |
CSV file containing tree measurements recorded on direct-seeded longleaf pine plots where trees were thinned in 1969 using several different levels of thinning (Study 3.20). Data such as diameter at breast height, tree height, height to base of life crown and crown class were measured and recorded every 5 years starting in 1974. |
| study_320.shp |
\Data\PlotLocations |
Shapefile (and associated files) containing approximate location of each plot in Study 3.20. |
| Data_and_Study_Description.pdf |
\Supplements |
Portable Document Format (PDF) file containing a short summary of Study 3.20 and a complete list and description of the variables included in the data file study320.csv. |
| Establishment_Report_320.pdf |
\Supplements |
PDF file containing a scan of the actual establishment report "Precommercial thinning direct-seeded longleaf pine on a medium site," which includes maps and description of the experiment. |
| Progress_Report_320.pdf |
\Supplements |
PDF file containing a progress report as of 1975 for this study, "Precommercial thinning direct-seeded longleaf pine on a medium site." It includes much of the establishment report and also some preliminary results. |
| Study_320_Plot_Map.pdf |
\Supplements |
PDF file containing a printed map of the plot layout. It is mainly a drawing of what is in the shapefile with some background graphics. |
