Prioritization of patches
Description
Prioritization of patches according to individual contribution to overall connectivity.
Usage
patch_imp(landscape, metric, vector_out = FALSE)
Arguments
landscape |
Object of class "lconnect" created by |
metric |
String indicating the connectivity metric to use in the prioritization. |
vector_out |
TRUE/FALSE indicating if the resulting spatial object should be recorded to file. |
Details
Each patch is removed at a time and connectivity metrics are recalculated without that specific patch. Patch importance value indicates the percentage of reduction in the connectivity metric that the loss of that patch represents in the landscape. The current version only allows the use of IIC or AWF.
Value
An object of class "pimp". This object is a list with the following values:
landscape |
Spatial polygon object of class "sf" (package "sf") with cluster identity and importance of each polygon. |
prioritization |
Vector with patch importance in percentage. |
