[Dataset:] Data from Tree Censuses and Inventories in Panama

Abstract: These are results from a network of 65 tree census plots in Panama.
At each, every individual stem in a rectangular area of specified size is
given a unique number and identified to species, then stem diameter measured
in one or more censuses. Data from these numerous plots and inventories were
collected following the same methods as, and species identity harmonized with,
the 50-ha long-term tree census at Barro Colorado Island. Precise location of
every site, elevation, and estimated rainfall (for many sites) are also
included. These data were gathered over many years, starting in 1994 and
continuing to the present, by principal investigators R. Condit, R. Perez, S.
Lao, and S. Aguilar. Funding has been provided by many organizations.

Description:

marenaRecent.full.Rdata5Jan2013.zip: A zip archive holding one R Analytical
Table, a version of the Marena plots' census data in R format, designed for
data analysis. This and all other tables labelled 'full' have one record per
individual tree found in that census. Detailed documentations of the 'full'
tables is given in RoutputFull.pdf (see component 10 below); an additional
column 'plot' is included because the table includes records from many
different locations. Plot coordinates are given in PanamaPlot.txt (component
12 below). This one file, 'marenaRecent.full1.rdata', has data from the latest
census at 60 different plots. These are the best data to use if only a single
plot census is needed. marena2cns.full.Rdata5Jan2013.zip: R Analytical Tables
of the style 'full' for 44 plots with two censuses: 'marena2cns.full1.rdata'
for the first census and 'marena2cns.full2.rdata' for the second census. These
44 plots are a subset of the 60 found in marenaRecent.full (component 1): the
44 that have been censused two or more times. These are the best data to use
if two plot censuses are needed. marena3cns.full.Rdata5Jan2013.zip. R
Analytical Tables of the style 'full' for nine plots with three censuses:
'marena3cns.full1.rdata' for the first census through 'marena2cns.full3.rdata'
for the third census. These nine plots are a subset of the 44 found in
marena2cns.full (component 2): the nine that have been censused three or more
times. These are the best data to use if three plot censuses are needed.
marena4cns.full.Rdata5Jan2013.zip. R Analytical Tables of the style 'full' for
six plots with four censuses: 'marena4cns.full1.rdata' for the first census
through 'marena4cns.full4.rdata' for the fourth census. These six plots are a
subset of the nine found in marena3cns.full (component 3): the six that have
been censused four or more times. These are the best data to use if four plot
censuses are needed. marenaRecent.stem.Rdata5Jan2013.zip. A zip archive
holding one R Analytical Table, a version of the Marena plots' census data in
R format. These are designed for data analysis. This one file,
'marenaRecent.full1.rdata', has data from the latest census at 60 different
plots. The table has one record per individual stem, necessary because some
individual trees have more than one stem. Detailed documentations of these
tables is given in RoutputFull.pdf (see component 11 below); an additional
column 'plot' is included because the table includes records from many
different locations. Plot coordinates are given in PanamaPlot.txt (component
12 below). These are the best data to use if only a single plot census is
needed, and individual stems are desired. marena2cns.stem.Rdata5Jan2013.zip. R
Analytical Tables of the style 'stem' for 44 plots with two censuses:
'marena2cns.stem1.rdata' for the first census and 'marena3cns.stem2.rdata' for
the second census. These 44 plots are a subset of the 60 found in
marenaRecent.stem (component 1): the 44 that have been censused two or more
times. These are the best data to use if two plot censuses are needed, and
individual stems are desired. marena3cns.stem.Rdata5Jan2013.zip. R Analytical
Tables of the style 'stem' for nine plots with three censuses:
'marena3cns.stem1.rdata' for the first census through 'marena3cns.stem3.rdata'
for the third census. These nine plots are a subset of the 44 found in
marena2cns.stem (component 6): the nine that have been censused three or more
times. These are the best data to use if three plot censuses are needed, and
individual stems are desired. marena4cns.stem.Rdata5Jan2013.zip. R Analytical
Tables of the style 'stem' for six plots with four censuses:
'marena3cns.stem1.rdata' for the first census through 'marena3cns.stem3.rdata'
for the third census. These six plots are a subset of the nine found in
marena3cns.stem (component 7): the six that have been censused four or more
times. These are the best data to use if four plot censuses are needed, and
individual stems are desired. bci.spptable.rdata. A list of the 1414 species
found across all tree plots and inventories in Panama, in R format. The column
'sp' in this table is a code identifying the species in the full census tables
(marena.full and marena.stem, components 1-4 and 5-8 above). RoutputFull.pdf:
Detailed documentation of the 'full' tables in Rdata format (components 1-4
above). RoutputStem.pdf: Detailed documentation of the 'stem' tables in Rdata
format (component 5-8 above). PanamaPlot.txt: Locations of all tree plots and
inventories in Panama.
