Tree stem growth data

Sixteen small files provide the stem diameters (‘Diamp’, cm) at the start of intervals (p), absolute growth rates, agr (‘Agrp-q’, cm/yr), and – as appropriate – species’ codes (‘Code’). The format is ANSI text (space-delimited). Fourteen files concern one or more of the three main caesalp species (Microberlinia bisulcata, Tetraberlinia bifoliolata and T. korupensis), for different time intervals and different size classes as uniquely indicated in their file names. Mean (± SE) of the agr-values are those given in Table 8 of the main paper. The two remaining files concern ‘other’ (Az) species measured in the P-plot and at the Isangele Road (IR) site for all large and some medium trees respectively. The former has species’ codes; the latter not because identifications were not certain. The Az mean (± SE) agr-values appear in the main paper text. A small script in R (agr_in) allows all of these files to be easily read into data-frames. To find relative growth rates, rgr, the time intervals will need to be applied to agr-values, and the resulting increments used to find final diameters and hence the rgr-values. The interval lengths are given in Table 8 ibid.
