a - biomass estimate includes only trees and is based
on allometric equations from: Brown, S.B., A.J.R. Gillespie, and A.E. Lugo.

b - biomass estimate includes all trees and shrubs >
1 m in height and > 1 cm in DBH; biomass based upon allometric equations
generated by sampling 126 trees.
c - biomass estimate based on the total harvest of plots,
with allometric equations used for trees.
d - biomass estimate based upon the total harvest of plots.
e - some data on nutrient concentrations and/or cycling
available for this site
f - disturbance was slash-and-burn agriculture, typically
carried out with 2 years cropping followed by 5 years of fallow.
g - site was burned 4 months after being cut; no wood was removed.
h - disturbance was slash-and-burn agriculture, with a
one year cropping cycle beginning with maize, then rice, then cassava and bananas.
i - approximate longitude.
j - approximate latitude.
k - altitude ranges from 200 to 500 m.
l - GSP estimated by assuming 75 mm precipitation per
month during the 4 month dry season.
m - soil order designation not available; assigned for
this compilation based on published description (excerpted in "Soil Description"
column).
