Is there an easy way to remove ground clutter?

Im working on adding a mountain range and the ground clutter is super anoying to manually delete one by one. Is there a quick way to remove all ground clutter in a sector?

 

That's something i'd like to know too. Only thing i can think of is putting in a really big facade then filling the sector with a terrain type.

 

I ended up using the "edit terrain" button and carefully added a thin layer of water to remove the clutter.

 

I prefer generate maps with water ground.
If you want to delete ALL (I said ALL) scenery, ground, npc, items, traps, ... in a sector, use "delete sector" option (right click on the ground). Be very careful, it deletes ALL and save immediately without asking you.
This is (i thing) the only way to delete scenery, ... without do it manually.

 

I actually tried that. It asked me if I wanted to delete, but once I clicked yes nothing happened.

Edit:

Or more specifically, the shrubs and trees which I wanted gone didn't get destroyed.

 

Okay, I understood the matter. Personally, when I destroy a sector, only water still remains but it's because I always generate maps with water tiles type. So I guess you generate with grass (or someone like that) so it removes the sector to its original tile type. So the only solution seems to be use the "terrain" tool and add water (but it's hard to use). :roll:
