a - site included in foliar nutrient subset
b - some data on nutrient concentrations and/or cycling
available for this site
c - biomass estimate includes trees, shrubs, and ground flora;
tree estimate uses allometric equations from: Freedman, B., P.N. Duinker., R.
Morash, and U. Prager. 1982. Canadian Forest Research Center Information Report
M-X-134.
d - biomass estimate based upon allometric equations (dry weight
on [(Diameter)2 x (Height)]) generated from 44 sampled trees.
e - biomass estimated by sampling several trees of average
size per stand and multiplying their averaged weight by the # of trees per hectare.
f - biomass estimate based on allometric equations (dry
weight on Diameter) generated from 75 sample trees.
g - biomass estimate does not include branch weights.
h - biomass estimate includes trees and understory; tree biomass
based upon allometric equations (dry weight on Diameter) generated from approximately
250 sampled trees.
i - biomass estimate includes only trees > 2 m in height;
biomass based upon allometric equations (dry weight on Diameter) generated from
200+ sampled trees.
j - biomass estimate includes shrubs.
k - biomass estimate based upon allometric equations from 2
papers by R.H. Whittaker and G.M. Woodwell: (1) 1968. Journal of Ecology
56: 1-25; 1971. (2) Pages 159-175 in Proceedings of the Brussels Symposium
1969. UNESCO, Paris, France.
l - biomass estimate based upon allometric equations from:
Tritton and Hornbeck. 1982. USDA Northeast Forest Experiment Station General
Technical Report NE-69. 46 pp.
m - biomass estimate based on allometric equations generated
by sampling 10-20 trees per species per location.
n - biomass estimate based on the total harvest of 100
m2 circular plots.
o - biomass estimate includes trees only.
p - soil order designation not available; assigned for
this compilation based on published description (excerpted in "Soil Description"
column).
q - the 1 and 3, 8 and 11, 13 and 16, 18 and 21, and 23
and 26 year old plots are the same plots resampled after three years.
r - the 55 year old plot is the same plot as the 40 year old
plot, sampled 15 years later.
s - authors list disturbance as "accidental burning or
wartime felling"
t - disturbance consisted of clear cutting and whole tree
removal followed by 3 summers of herbicide application.
u - approximate altitude.
v - approximate longitude.
w - approximate latitude.
x - altitude ranges from 15 to 170 m; authors list 90 m as
average.
y - altitude ranges from 400 to 700 m.
z - altitude ranges from 500 to 650 m.
aa - closest climate station was 2 degrees east and 3
degrees south of site.
bb - closest climate station was 3 degrees south of site.
cc - GSP estimated by assuming an even distribution of
precipitation throughout the year.
