Would be nice to know how those are calculated and what the methology is.

Do you have a worldwide version?

Found this

North American boreal and western temperate forest vegetation [02_1]

cool map, putting gothenburg and its surroundings firmly in the oceanic vegetation zone, where it always has belonged.
my grandma once told me that there weren't any confiers at all along the swedish westcoast when she was grewing up, but was later introduced because of confier-plantations (that were supposed to work as a swedish wood reserve during ww2). since then, we've only had hemiboreal vegetation here, even though it dosen't reflect that in the current climate.

anyway, interesting map.

Subarctic Mo i Rana hemiboreal, Helsinki thermoboreal (whatever that means).

Otherwise I think it's quite accurate, though quite a bit crude for Finland at least.



The hemiboreal zone seems to follow quite well the darkest growing season area, and the second darkest red area follows quite well the natural habitat of maple in Finland, and where the biodiversity is high and forests mixed:


The lightest purple is the transition zone with mixed forest and subarctic forest, getting more 'pure' subarctic forms. The lightest purple is also the rough border that it's feasible to grow wheat for example. Follows quite well the prevalence area of black alder, also the original map.


Light orange and yellow is quite close to the original map, the last zone where the forests are dense and trees high, before turning to this: https://www.google.fi/maps/place/131...00b551554bad30

Quite good map otherwise except a bit crude maybe, and not taking account the many watery areas in Finland and elevation, which is generally quite low, but starts to make a difference around 63N.
