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
