LandR
packageUtilities for 'LandR' suite of landscape simulation models. These models simulate forest vegetation dynamics based on LANDIS-II, and incorporate fire and insect disturbance, as well as other important ecological processes. Models are implemented as 'SpaDES' modules.
LandR
packages use the following options()
to configure behaviour:
LandR.assertions
: If TRUE
, additional code checks are run during function calls.
Default FALSE
.

FireDisturbance()
simulates post-fire mortality, serotiny and regeneration sequentially occurring after a fire.
Post-fire mortality is assumed to be 100% (stand-replacement). The serotiny and regeneration
algorithms are based on those in LANDIS-II Biomass Succession extension, v3.2.1, with modifications
Requires the following objects in sim
(passed as sim$*
):
@template FireDisturbance.
For any given burnt pixel, the function begins by killing all cohorts
(i.e. removing them from cohortData
). Then it activates serotiny for
serotinous species that had been present pre-fire, and reprouting for reprouter
species. Whether a species successfully regenerates via serotiny or resprouting
depends on its traits (whether it is serotinous, resprouter, both or none;
species
table), pre-fire cohort age (in cohortData
table), its light/shade
requirements (species
table) and its local maxB
(speciesEcoregion
)
table (see Scheller & Miranda, 2015 and Scheller & Mladenoff, 2004 for details).
Unlike in LANDIS-II Biomass Succession extension, v3.2.1, here we allow serotiny
and resprouting to occur in the same pixel to reflect the competitive advantage
of reprouters. However, for a given species only serotiny (takes precedence)
or resprouting can be activated.
The species
table must contain the columns:
sexualmature
– age at sexual maturity
postfireregen
– post-fire regeneration strategy ("serotiny", "resprout" or "none")
shadetolerance
– shade tolerance value relative to other species.
resproutage_min
, resproutage_max
– minimum and maximum age at which species can repsrout
resproutprob
– probability of resporuting success (before light/shade suitability is assessed)
FireDisturbancePM()
simulates partial post-fire mortality, serotiny and regeneration
sequentially after a fire. The level of mortality depends of fire severity,
and, by default, follows the mechanisms in LANDIS-II Dynamic Fire System v3.0.
Serotiny and regeneration algorithms algorithms are based on those in
LANDIS-II Biomass Succession extension, v3.2.1, with modifications (see FireDisturbance()
).
Requires the following objects in sim

):
@template FireDisturbance

fireRSORas
(Critical spread rate for crowning)
fireROSRas
(Equilibrium Head Fire Rate of Spread)
fireCFBRas
(Crown Fraction Burnt)
minRelativeB
Rasters of fire behaviour properties (fireRSORas
, fireROSRas
and fireCFBRas
)
can be calculated using the cffdrs
package.
The species
table must contain the columns:
firetolerance
– fire tolerance value relative to other species.
longevity
– maximum species age
sexualmature
– age at sexual maturity
postfireregen
– post-fire regeneration strategy ("serotiny", "resprout" or "none")
shadetolerance
– shade tolerance value relative to other species.
resproutage_min
, resproutage_max
– minimum and maximum age at which species can repsrout
resproutprob
– probability of resporuting success (before light/shade suitability is assessed)
PeatlandThermokarst()
simulates tree cohort survival/mortality after
peatland permafrost thermokarst. The level of mortality depends on species
tolerance to thermokarst, determined by the thermokarsttol
trait column
in the species
traits table. At the moment, this level of tolerance is used
as the proportion of a cohort biomass that survives (is kept) when a pixel undergoes
thermokarst. This is similar to the partial disturbance effects used in LANDIS-II Biomass
Harvest v4.0. Requires the following objects in sim
(and passed as sim$*
):
thawedPixIDs
treedThawedPixelTableSinceLastDisp
wetlands
cohortData
pixelGroupMap
rasterToMatch
species
speciesEcoregion
inactivePixelIndex
The species

The function will create sensible parameter ranges for A, k and p parameters
of the Chapman-Richards and Logistic growth curves and attempt to run a
forward step-AIC procedure to add covariates to the linear component of the
model (on the A parameter – the asymptote). The maximum number of covariates
to add is determined by maxNoCoefs

A logical indicating whether some internal tests should be run to

Default: |
This function regenerates pixelGroup
s in situations where
disturbances are not stand-replacing and create survivor and dead
cohorts in some, but potentially not all, pixels of a pixelGroup
. This is
necessary to prevent reintroducing dead cohorts that were not affected
in the other pixels of the same, original, pixelGroup
.
ATTENTION This function alone will not generate final pixelGroups
,
and will likely need to be followed by an updateCohortData
run.
The function:
creates a table of undisturbed pixels, and disturbed pixels with dead and surviving cohorts
but not new cohorts (e.g. from serotiny/resprouting) – these are added by updateCohortData
;
generates pixelGroups
considering these dead and surviving cohorts – this ensures that
we account for cohorts that died in some but not all pixels of a given pixelGroup
;
then removes dead cohorts (as they should not be in tables for downstream
functions like updateCohortData
) and recalculates pixelGroups
– this ensures that
pixels that became similar/dissimilar after the death of some cohorts can form new pixelGroups
.

Simulate seed dispersal using user defined function. This is a "receiving pixel" focused
dispersal approach.
It is the "potentially receiving" cell that looks around itself for potential seed sources.
If it finds a single seed source, that passes the probability function described by the
dispersalFn
.
If this passes a comparison to a uniform random draw, then the receiving cell is deemed to have
a "successful" dispersal for that species.
This function can therefore only be used for a relatively specific situation
where there is a yes/no returned for each potential receiving cell, i.e., not abundance.
This function is also not cumulative, i.e,. there is no higher abundance of seeds received if
a receiving cell has lots of seed sources around it vs. a single seed source.
The difference will come with a higher probability of successfully receiving a "seed".

dispersalFn
(temporarily unused as code is converted to Rcpp – the default dispersalFn
is hard coded within the spiralSeedDispersal
function that uses C++) must be an expression
that returns a probability distribution.
Because it is a dispersal kernel, it must be a probability distribution.
The expression that can take an argument named "dis" (without quotes) as this will be
calculated internally and represents the distance from the initial (receiving) pixel
and all active pixels within that cluster of active pixels.
LandR includes the Ward()
kernel as defined in the LANDIS-II documentation.

establishprob
This section takes the cover as estimated from the mature tree cover and
partitions it between resprouting and seeds Unfortunately, establishment by
seed is not independent of resprouting, i.e., some pixels would have both
Since we don't know the level of independence, we can't correctly assess how
much to discount the two. If there is resprouting > 0, then this is the
partitioning:
establishprob = f(establishprob + resproutprob + jointEstablishProbResproutProb)
If jointEstablishProbResproutProb
is 0, then these are independent events
and the total cover probability can be partitioned easily between seeds and
resprout. This is unlikely ever to be the case. We are picking 50% overlap as
a number that is better than 0 (totally independent probabilities, meaning no
pixel has both seeds and resprout potential) and 100% overlap (totally
dependent probabilities, i.e., every pixel where there is seeds will also be
a pixel with resprouting) This is expressed with the "* 0.5" in the code.

the column name to use from |
and only for the following speciesTable$Area
s:
Boreal Shield West (BSW);
Boreal Plains (BP);
Montane Cordillera (MC).
Note that BSW and BP areas correspond more closely to the region considered in Table 2 of Burton & Cumming (1995), while MC will correspond to both tables.
Of the above species, shade tolerance values are changed for Abies spp, Picea spp, and Tsuga spp to better reflect the western boreal.
When different longevity/shade tolerance trait values exist for a given species, the minimum
value across Area
's (BSW, BP, MC) is kept.
ATTENTION: if none of species in species
are from BSW, BP or MC area this function will not
change any values.
All other species/Area trait values follow Dominic Cyr and Yan Boulanger's trait values (https://raw.githubusercontent.com/dcyr/LANDIS-II_IA_generalUseFiles/master/speciesTraits.csv).
