Grass not growing back?

[Florius]

I'm not sure if this is a bug or just something missing or whatever, but I noticed that in 2 games I had poisoned ships, and after that the grass died, which I read in the changelog. That's all fine and fun, but after I destroyed the ships, the grass hasn't grown back yet. And I am playing for 2+ (in game!) years!
So is it a bug, or...?

I have noticed grass takes an asinine long time to grow back. Flashstorms leave scars on the landscape for years. I think it's partly because animals eat the grass and slow down the spread of grass

Same with me. At year 3 I had just NOTHING growing in the middle of my map. At year 12 it is the same.

And here is my bug report:

Apparently grass only grows from other grass sending flying seeds in random adjacent tiles (5 tile range), so if something burns enough of it, events animals etc, you can make an entire area barren. I agree it can easily get to the point where it's frustrating. Even if animals eat everything, grass should grow back kinda randomly on appropriate soil, maybe triggered by rain, I dunno.

And animals will eat the newly sprouted grass very quickly after an event. So yes it takes a long time for grass to return.

It also grows off the edge of the map I believe

This, grass growth should be triggered by rain (if it isn't already). The option to plant grass seeds would be nice too.

personally i think the solution is an animal eating grass has a decent chance to sow a seed when doing so, a lot of seeds travel on hungry animals IRL.

I agree, New grass should come from:
Adjacent tiles of grass
Animals which spawned at the map edge (only "sowing" one or two tiles at random intervals)
Random encroaching from the map edge
Colonists spreading seeds? (would certainly help to maintain a pasture)

Grass in Rimworld spreads from other grass. The range is only about 2 squares. I had grass grow back after poison ship.

In the meantime, you can plant dandelions, then delete the growing zone. Dandelions are the only plant you can sow that spreads outside growing zones.

Or just massively increase the grass seed spawning and growing speed.

Would be super OP because animals feed on it.

Spawning some random plants all over the map sounds like more reasonable thing.
