The selection of the regional laimax as the laimax values used further is done in the [initmanage.c function](https://gitlab.pik-potsdam.de/brunel/lpjml-med/-/blob/main/src/landuse/initmanage.c) depending on the LAIMAX_REGION configuration.

## Tree density
As well as the laimax per cft and the default irrigation system, tree density is given per region.
Below, the file [manage_morocco_treedensregion.par](https://gitlab.pik-potsdam.de/brunel/lpjml-med/-/blob/regional_laimax/par/manage_morocco_treedensregion.par) which gives the tree density per region for Morocco. (only possible for one country run so far)
