Species table for the SWO variant of the CONIFERS growth model

Description

These are species codes used for the SWO variant of the CONIFERS growth model.

The swo data frame has 38 rows and 13 columns.

Usage

data(swo)

Format

This data frame contains the following columns:

idx
The index of the species code that is used within the CONIFERS source code.
code
The alpha-numeric code that is used during data input, normally in the field data recorder. These are used in the summaries and outputs rather than the species names.
fsp
The functional species code (found in the coefficients) that is used to project the plant record. Every species code is mapped to a single functional species code. See another manual page.
name
The long name for the plant species.
organon
The code that should be used to export the species to the ORGANON growth and yield model. See http://www.cof.orst.edu/cof/fr/research/organon/index.htm for more details.
cactos
The code that should be used to export the species to the CACTOS growth and yield model. See http://www.cnr.berkeley.edu/~wensel/cactos/cactoss.htm for more details.
fvs
The code that should be used to export the species to the FVS growth and yield model. See http://www.fs.fed.us/fmsc/index.php for more details.
endemic.mort
is a percent for the endemic mortality, where (0.002) means that two tenths of a percent of the trees of that functional species type will be "killed" for each year of projection.
max.sdi
is the maximum stand density index the functional species can obtain before competition induced mortality is applied.
browse.damage
is a percent for the browse damage, where (0.002) means that two tenths of a percent of the trees of that species type will be "killed" as a result of browse damage.
mechanical.damage
is a percent for the mechanical damage, where (0.002) means that two tenths of a percent of the trees of that species type will be "killed" as a result of mechanical damage.
genetic.worth.h
is the average expected level of gain, expressed as percentage, for diameter at a given age. Values are bounded by 0 and 20.
genetic.worth.d
is the average expected level of gain, expressed as percentage, for diameter at a given age. Values are bounded by 0 and 20.

Details

The dataset is similar to the swo.txt file that is distirbuted with the GUI version of CONIFERS. A species lookup table is nothing more than a data.frame with specific column names.

Examples

library( rconifers )

# load the Southwest-Oregon species coefficients into R as a data.frame object
data( swo )
#view max sdi
swo$max.sdi
#change the max sdi for Douglas-fir to 600
swo$max.sdi[1]<-600

## set the variant to the SWO variant and use the new Douglas-fir max sdi
set.species.map(set.variant( 0 ))
