## Wood Specific Gravity for Tropical Tree Species

### Description

This dataset contains information a subset of the full data set of the wood specific gravity (`wsg`) for tropical tree species for calculation of above ground biomass. Only species found at the CTFS site, BCI, are included in the file distributed with this package. Species name codes as found in CTFS datasets, full latin name for Family, Genus and Species, the CTFS site the species has been recorded at and the level of identification used to assign a wood specific gravity.

### Usage

    data(wsg.ctfs)

### Format

A data frame with 5761 observations on the following 7 variables.

`wsg`
  a numeric vector, wood specific gravity
`idlevel`
  a character vector, level of matching wsg with species name
`site`
  a character vector, CTFS site for species
`sp`
  a character vector, CTFS species name code
`genus`
  a character vector, latin genus
`species`
  a character vector, latin species
`fam`
  a character vector, latin family

### Details

This data file is used for the analysis of above ground biomass in particular with the function `biomass`. It is the parameter `wsgfile`.
