What can you 'harvest' with a builder?

[bbbt]

I'm a bit confused what you can or can not harvest in the game. Obviously forest/jungle/etc definitely, but I thought you could harvest bonus resources (ala stone/wheat/sheep)? Or is there just a tech I haven't unlocked yet - it's certainly not giving me the option on the sheep I want to remove.

I'm not sure if it is a tech thing, but to clear a bonus, you should see a sickle clearing some wheat as an option. If you hover over that icon there is probably not a tooltip, but I'd imagine it's there and not lit up for whatever reason. No idea why though.

That icon appears on the top bar of the builder's action window, separate from the "normal" builder options that appear off to the left (such as the bulldozer button, which is used to remove terrain features, like woods and jungle).

you have to be on your border to harvest a bonus resource, features like jungle you can harvest from anywhere, even from inside an enemy border.

There are techs required for each resource (pottery for wheat/rice, etc.)
