Creat a new patch

[SelenaChou]

Dear all,

I am using CLM5. Spatial land surface heterogeneity in CLM is represented as a nested subgrid hierarchy in which grid cells are composed of multiple land units, snow/soil columns, and patches. I find that at most 79 types of patches are used in CLM5, including not_vegetated, trees and crops. I wonder if I add a new patch and set new rules in each process for this patch? Has anybody made a similar attempt?

Generally, we recommend "taking over" an existing plant functional type, rather than adding an entirely new one. There is some discussion of this here:

How to add a new Plant Functional Type to CLM?

I am trying to define a new Plant Functional Type (PFT) in the land cover. I only want to plant this species in a particular area, so I thought directly change the existing PFT may not work, instead, I would need to define a new PFT. I checked the "PCT_NAT_PFT", which seem to be fully occupied...

Thanks, Oleson! That helps a lot!
