Enumerations of permanent forest plots

There are six files and a species-codes list. The format is ANSI text (space-delimited). For the P-plot the large trees (stem diameter ≥ 50 cm) alive in the first (1991) and second (2005) enumerations are given in p91lar.txt and p05lar.txt. The subplot columns (‘Col’) are numbered 1 – 33 (from east to west), and the rows (‘Row’) lettered ‘A’ – ‘J’ (from north to south: see Fig. 2a in main paper). The X- and Y-coordinates (‘EE’ and ‘NN’) are in metres from the SW-corner (origin) of the plot. ‘Tag’ is the permanent tree number, and ‘Code’ the eight-character designations of the species’ names. Almost always, the first four characters of this code are the starting letters of the genus name and the second four those of its epithet (and where species are not known to species level of the form “sp1", for example, or “spnv”). Note one line is for indeterminates “Indet”! The full list of Latin names are given in codes.txt: authorities and family names are listed in Appendix B to the paper. Recording periods for the enumerations of the P-plot, with their median dates in 1991 and 2005, the P-plot extensions around 2000, and of the NW-plot, with median date in 2003, are all to be found in the main paper. ‘Diam1' (in 1991) and ‘Diam2' (in 2005) are the tree stem diameters in centimetres. The exact heights of measurement necessarily differed across trees: these are not given here – refer to the Methods in main paper and Appendix A there for details). Where a tree had a substituted (estimated) diameter (see Appendix A for reasons and methods used) this is indicated by a value of 1 in the column ‘Substn’ (1991-measured trees only). In p91lar.txt, ‘Stat2' indicates alive (1) or dead (0) condition by 2005, whilst in p05lar.txt it shows whether a tree was a survivor from 1991 (1) or a recruit into the size class by 2005 (2). (‘Stat1' by definition was always 1.) The same system of variable names is applied for the NW-plot large trees in nw03lar.txt. Here ‘Col’ runs again east to west from subplot columns 35–49, and ‘Row’ north to south as JN–XN (see Fig. 2b in main paper; and conforming to the overall grove map in Fig. 1 ibid.): there has been no main second enumeration of the NW-plot (except for the two part censusses in 2009 and 2001 – see main paper). The P-plot extensions are in pe00lar.txt. The six extensions travel north and south of their corresponding P-plot edge positions: coordinates (‘E’ and ‘N’) are for within-subplot distances only. Enumerations of medium-sized trees (stem diameter 10 –< 50 cm) are listed in p91med.txt and nw03med.txt. ‘Col’ and ‘Row’ again define the subplots measured, ‘Code’ and ‘Diam1' have same meaning as for large-tree files. For the P-plot, ‘Stat2' indicates whether the tree by 2005 was alive, either remaining in the medium size class (1) or advancing into the large one (–1), or was dead (0). Recruitment was not recorded. The NW-plot has had no second enumeration of medium trees so there is no status column. For the P-plot where the variable ‘Substn’ has a value of 1, the tree diameter was substituted (estimated): see Appendix A to main paper for reasons and methods used.
