Table. 1. Table 1 gives some numeric summaries of the P.R. data. The
1,2 3 under the "study area"column are the three CWD (Vogt
et al) plots in each of the sites. The # of trees is obvious. The mm
of growth is radial growth. The
basal area increment is the amount of basal area added by the
accrued growth expressed as a percent of the original basal area.
The mm/2 months is the 8 month growth
total derated to a 2 month growing season basis for comparison to
Hubbard Brook.

Table 2. Table 2 is the raw data for each of the plots. The first # is the tree tag #. The 4 letter code is
the species code. (I would like to replace these with the official codes used by the P.R. research
group - if someone will give them to me.). The third number is the diameter of the tree at the band (
which is more or less at dbh). The next number is the cm of dendrometer band
expansion(circumference). The last number is the mm of radial growth. Our species are:
Cecropia peltata CEPE
Sapium SASP
Unknown XXXX (We have no clue! Help!)
Dacryodes excelsa DAEX
Manilkara bidentata MABI
Inga fagifolia DISP
Casearia sp. CASP
Syzygium jambos SYJA
Ochroma pyramidale OCPY
Roystonea borinquena ROBO
Sloanea sp. SLSP
Buchenavia capitata BUCA
