add_connected_constraints

Add constraints to a conservation problem to ensure that all selected planning units are spatially connected to each other.

add_corridor_constraints

It is important to maintain connectivity between reserves. However, some areas are more difficult for species to traverse then other areas. As a consequence, even though reserves may be connected, species may not be able to move between reserves if the areas connecting them are barriers to dispersal.

This function adds constraints to ensure that corridors connect reserves and that individuals from all species can utilise the corridors. Friction Raster-class objects area used to show each dificult areas are to traverse.

add_locked_in_constraints

Add constraints to ensure that they are prioritized in the solution. For example, it may be desirable to lock in planning units that are inside existing protected areas so that the solution fills in the gaps in the existing reserve network.

add_locked_out_constraints

Add constraints to ensure that certain planning units are not prioritized in the solution. For example, it may be useful to lock out planning units that have been degraded and are not longer suitable for conserving species.
