tst.bci90.mult {CTFS} | R Documentation |
The structure of the CTFS Long Term Forest data set of measurements of multiple stems. In addition to the measurement of a main stem, if a tree has other stems that are greater than 10 mm in dbh, they are also measured for diameter (DBH) only. These measurements are recorded in this file. These measurements are useful for computations of basal area and biomass but are not normally used for computations of indiviual tree dynamics.
data(tst.bci90.mult)
tst.bci90.mult
and tst.bci95.mult
are subsets of the
complete multi stem data files for BCI census 1990 and 1995,
respectively. tst.bci90.mult
contains 584 records.
tst.bci95.mult
contains 548 records. Only the the multiple
stem measures of trees in the tst.bci90.full
and
tst.bci95.full
, respectively are included. The tag
number is repeated for as many multiple stems as were measured for
the main stem.
