A player, 8 July 2007
cartographers has the action Recon open:Bow this card:target a province, during the first battle that takes place at that province, negate the [b]effects[/b] of the first reaction or terrain action taken by other players there
1.If I'm attacking and i take the first action, they reinforce the gates, its negated via cartographers, than, after my action, they play a terrain, is the terrain negated?
2.When the terrain is played and its effects are negated, does that mean that it is discarded or that it does nothing except for be a terrain(as in i couldn't play one or my opponent couldn't play a second one)?

It's "or," not "and". No.

The former. (Fixed.)
