SCGLR (version 1.1)

genus: This is the data to be included into the package

Description

genus gives the abundance of 27 common tree genera in the tropical moist forest of the Congo-Basin and 40 geo-referenced environmental variables on one thousand 8 by 8 km plots (observations). Each plot's data was obtained by aggregating the data measured on a variable number of previously sampled 0.5 ha sub-plots. Geo-referenced environmental variables were used to describe the physical factors as well as vegetation characteristics. 14 physical factors were used pertaining the description of topography, geology and rainfall of each plot. Vegetation is characterized through 16-days enhanced vegetation index (EVI) data.

Arguments

gen1
to gen27 are the abundance of the 27 common genera on each plot
altitude
is the above-sea level in meters
pluvio_yr
is the mean annual rainfall
forest
forest type classified into seven classes
pluvio_1
to pluvio_12 are the monthly rainfalls
geology
is a 5-level factor giving the geological substrate
evi_1
to evi_23 are the means over 10 years of the enhanced vegetation indexes for each successive 16 days period using MODIS images
lon
and lat are the longitude/latitude of the plot centers
surface
is the surface of the sampled area contained in each 8 by 8 kms aggregated plot
