Will the vegetation come back when a fire happens using CLM5 BGC-Crop mode?

[Xueli Huo]

Hi

I never pay attention to the fire module in CLM. I was running CLM5 BGC-Crop, and the fire module is turned on by default.
My silly question is that after a fire happens for example in a grid cell, will the the vegetation in the grid cell come back or not? And what variables to check to see whether the vegetation is dead or alive (not burnt or re grow) after a fire?

Sincerely,

Good question, I assume it does come back, although I don't see anything explicit about it in the technical note. I would assume TLAI could be checked.
I will check with others.

Hi Xueli,

Yes, the vegetation in CLM grows back after fire. You can look at TOTVEGC to see vegetation carbon pools (this is for alive vegetation) and GPP to see the carbon fluxes from photosynthesis.
