env.file: Environmental Layers File
In akeyel/spatialdemography: A Spatially Explicit Metacommunity Model

Description Details

Environmental settings. There should be a row for every environmental layer included in the model. In the case of pre-generated, unchanging landscapes, only the env.lbl, landscape.identifiers, and env.change.freq fields are important.

Input	Example	Description
env.lbl	mowing	A label for the environmental layer.
landscape.identifiers	M	A single letter identifier for each environmental layer.
env.type	cover	A code for the type of environmental layer. See env.type for more details.
cover.levels	0.75;0.25	Cover levels for each value of the environmental variable (separated by a semi-colon). Only applicable if env.type is set to cover. See env.type for more details.
param1	0;1	A parameter guiding the construction of the environ-mental layer. See env.type for more details.
param2	NA	A second parameter guiding the construction of the en-vironmental layer. See env.type for more details.
cond.var	landcover	If NA, the current landscape element will be produced independently. Otherwise, this generation of this environmental layer will depend on the environmental layer specified here. In theory multiple environmental layers could be specified. In practice, this functionality is not fully supported.
cond.vals	1	Indicates which values in the other layer should be con-sidered potentially suitable (this layer will be assigned values of 0 for all other values of the conditioning layer). If cond.var is NA, this should also be NA.
env.change.freq	10	Indicates how often the environment should change. A 0 turns off environmental change. There is currently no way to get an irregular change interval, or to stop environmental change mid-scenario based on this parameter.
env.change.type	swap	Indicates what type of environmental change should take place. See env.change.type for more details.
env.change.mag	NA	Describes the magnitude of the environmental change. See env.change.type for more details.
