Right now, at 6 mbar CO2 and waay subantarctic temperatures you'd be hard
pressed to have any detectable (that's a far cry from terraforming) microbial
activity. Notice that any detectable (assuming, the methane is biogenic)
activity comes from the few first km of submartian rock.

Most of it is underground. Any life capable of living on the surface (i.e.
not under ice) would be wonderful to behold, but I'm not counting on it.
