Can I make roof above pasture and keep grass ?

[Plopaplopa]

I'm tired of being assaulted by Giant Keas, so I would like to build big walls and a roof around my pasture area. Will it damage the grass ?

[Terminal]

It will not. In fact, grass will regrow in that area as long as it is not overgrazed into oblivion.

I am not entirely certain if it is the same in V.50 as it was in past versions, but ANY area exposed to the surface, even if covered up with construction later, is always considered to be outdoors for the rest of eternity. Cave Fungus won't even grow there, I believe.

Find a place that will grow cave lichens or whatever as soon as you can and dig out a new underground pasture.

Yes. Sunlight passes through constructed floors, so you can use them as a roof to protect a Surface Pasture. You can even dig down and put that Surface Pasture deep underground with that constructed floor 'roof'.

Thank all of you for the answers, gonna make that deep underground pasture after building that floor / roof
