Re-seeding wild plants

[schizmo]

You can plant your own trees in any growing zone, and the Strawberries are the same as the wild Raspberry bushes. Aside from maybe Agave (I haven't had much experiences on maps with Agave), every useful plant can be planted by the player, even dandelions. I'm not sure what it is that you are all looking for, except maybe grass? Planting haygrass is more effective for feeding animals and natural grass is more dangerous than anything because it's highly flammable, so aside from aesthetics you really shouldn't worry about it too much. If you leave it alone, it will grow back within a few seasons anyway

Strawberries are different in a crucial aspect:  they don't self-spread beyond their planted areas, neither do dandelions.  It isn't really practical to farm the entire map when its been de-foliated by events.

This severely limits foraging for untame herbivores, which in turn means limited hunting for untame carnivores, and your map winds up largely lifeless.

Lack of meat (beyond whatever you already have tamed) can then become a significant effect.

And no, even after many seasons, maps with hills, mountains or boreal maps with waterways never regrow foliage in the interior because the seed distribution doesn't cross those barriers.
