Description Usage Arguments Value
Grows the plant community, modelling fire behaviour against a weather dataset for every age, then summarising all behaviour into risk and impact statistics. Allows trees an older age than understorey to represent lower severity fire histories

base.params |
Parameter input table |
weather |
A dataframe with the four fields: tm - Sequential numbering of the records T - Air temperature (deg C) W - Wind velocity (km/h) DFMC - Dead fuel moisture content (proportion ODW) |
growth |
A dataframe with the six fields: species - Name of the species consistent with other tables max - Maximum plant height (m) |
cover |
A dataframe with the fields: species - Name of the species consistent with other tables constant - Mean plant separation (m) that does not change with age exp_a - The first constant in an exponential function describing plant separation with tsf exp_b - The second constant in an exponential function describing plant separation with tsf |
Flora |
A dataframe with the fields: record - a unique, consecutively numbered identifier per site species - the name of the species, which will call trait data from 'default.species.params' moisture - the moisture content of the species in whole numbers (eg 1 for 100 stratum - numeric value from 1 to 4, counting from lowest stratum comp - base, he, ht, top & w - canopy dimensions for that species (m). he and ht are optional clump - mean ratio of clump diameter to crown diameter openness - ratio of gap to clump size |
jitters |
Number of repetitions for each row in the weather table |
ageStep |
The number of years between age classes to be examined |
firstAge |
The youngest age class to be examined |
steps |
The number of age classes to be examined after firstAge |
tAge |
The age of trees at the commencement of the run |
l |
Variation around input leaf dimensions |
default.species.params |
Leaf traits database |
Ms |
Standard deviation of LFMC |
Pm |
Multiplier of mean LFMC |
Mr |
Truncates LFMC variability by +/- Pm * LFMC |
Hs |
Standard deviation of plant height variations |
Hr |
Truncates plant height variability by +/- Hr * height |
a |
The number of the record to be modelled |
suspNS |
Name of the fuel in the suspended layer |
density |
density of the wood in the suspended layer (kg/m3) |
test |
An isotherm for which the height will be reported |
hKill |
The percentage of tree canopy above which a risk boundary is crossed (0 - 100) |
updateProgress |
Progress bar for use in the dashboard |
